plastering interior walls with interior plaster

Plasters are wall coverings made of plaster mortars or similar coating materials. A distinction Interior plasters for the design of interior walls and exterior plasters for plastering facades. Interior plasters are applied on the ceiling or wall surfaces in the interior and consist of one or more plaster layers in different thicknesses. The different types of plaster meet - depending on the composition - building physics in the first place and of course aesthetic tasks.

plastering interior walls with interior plaster

After plastering can be painted or papered, but there are also decorative plasters in different colors, which are becoming increasingly popular as an alternative to wallpaper or paint. The finish is pleasantly easy in most cases: the decorative plasters can tinted different colors, applied with a paint roller or trowel and finally structured with different techniques and be designed.

What types of plaster there, how they are processed and then made are described in detail on this page.

Technical principles

Basically plasters must be adapted to the existing subfloor. The rule is: "soft to hard", The hardness of the individual layers should thus outwardly, i.e. decrease towards the surface. This is especially true for mineral plasters on solid walls. If this principle is adhered to, drying stresses and thermal expansion can be absorbed by the teeth and there are no cracks. To a lesser extent occurring fissures are sometimes but still can not be avoided, causing no structural damage.

In thermal insulation renders and plasters on thermal insulation systems the prescribed rule does not apply. Here movements are captured by a soft intermediate layer. Adhesive, insulation board, reinforcement and plaster - - When using a composite thermal insulation system, all components should always come from a single vendor. Only if tested products are used in combination, the building approval is secured.

Basic plaster or decorative plaster?

are primarily basic plasters from decorative plaster to distinguish. Yourselfers often approach the subject plastering with some respect. Here, at least a basic plaster by skilled handymen can easily be applied on their own performance. The order of decorative plaster is not rocket science.

While basic plasters are used to pave surfaces, decorative plasters are then applied to the attractive wall decoration. So for example, should a masonry are provided with a decorative plaster, must first with a base coat or all joints plasterboard a flat surface to be created. Thereafter, in accordance with primed and then the decorative plaster, such as roll Putz or Reibeputz applied.

Testing and pre-treatment of the substrate

The condition of the substrate is for nosing essential. Therefore, the first step is the thorough examination of the plaster base: it must reasonably just, sufficient dry, frost-free and absorbent be and may not sanden still chalks. Calcium deposits, salt efflorescence, mold covering and loose or crumbly parts are removed. The components must be protected against rising and extrinsic moisture. Mineral substrates are visual inspection, wipe sample and Scratch checked with a sharp object on carrying capacity.

All loose parts and sanding surfaces are completely removed. To be plastered surface is then cleaned thoroughly with a broom or brush. The sinterskin in new concrete surfaces is removed with a wire brush or a wire brush. Cleaning-friendly surfaces are brickwork, Kalksandsteinwerk, hollow masonry block, as well as absorbent concrete, plaster difficult substrates are slightly absorbent, e.g. smooth concrete. the respective preparation is selected according to the substrate and of the following cleaning order. A primer or treatment with a junction is in many cases necessary, for example, if the substrate is very absorbent, such as plasterboard or strongly SANDET / chalk.

mineral plaster

Natural building for a comfortable living environment

For centuries, mineral plasters serve as a wall coating for buildings and have lost none of their significance to this day. On the contrary, the qualities of the material mineral plaster are more in demand than ever.

According to DIN 18550 mineral plasters next aggregates, such as sand or flour, different binders can as building lime, lime / cement mixtures, cement, gypsum or clay, included. are divided mineral plasters - depending on the composition and material properties - in various types of plaster: exterior plaster, interior plaster, upper and lower plaster. These plasters are generally suitable for indoor use and many also for outdoor use. Whether a plaster is suitable for outdoor use, is critically dependent on the information contained binders.

Interior plaster, exterior plaster and special plasters

in the outdoors the plaster extreme weather conditions must be able to withstand in particular moisture, extreme temperature fluctuations and hard UV light. Therefore, external renders need special weather resistance, as they have based plasters based on lime cement or cement, have.

For the interior come other binder systems in question, which bring many environmental building benefits. Above all, plaster, gypsum-clay, clay and hydrated lime plasters must be indicated here. Plasters can be used very diverse. In the concealed, they are grateful surfaces for painting and wallpapering, as decorative plaster form an attractive visual interface.

typical Basecoats are Machine gypsum plasters and gypsum plasters hand. Machine gypsum plasters are used in large areas, because they are the most economical solution. Hand plasters are ideal for renovation or plastering smaller areas.

To optimize the plaster for your respective properties are added to your part of the manufacturer special additives. These give them in terms of workability and functionality characteristic features. a special shielding plaster can be produced gypsum with the high-performance material carbon, which is used wherever the shield electrical and electromagnetic fields is necessary, for example by the combination of the classical building material. are another example of functional plasters Plasters to improve the room acoustics, which are often used as decorative plaster because of their appearance.

Roll plasters and rubbing plasters

Grater plasters have a coarser grain than the fine roll plasters - up usually from 2 millimeters. Their structure they obtained by rubbing the final reared on grain strength plaster. In this case, result depending on the direction of movement, different structures that can extend circular, horizontally or diagonally. Reibeputz available on synthetic resin or mineral based. (How different from synthetic resin plaster Mineral plaster is bechrieben in more detail below.)

Alternatively, the walls can also trowel and roll Putz shape. Here, a trowel or a paint roller for structuring is used. Irregular surface structures that still yield a uniform pattern, are the attractions of this plaster. is achieved the desired effect by the rolling plaster first applied and is then machined with tools such as trowel, brush, foam or structural role.

Before plastering the wall, you should practice on a sample surface. For that you use for. B. Remainder of particle board or plasterboard. In this way you can easily determine whether your idea of ​​a "ideal structure" can be put into action. Here you can experiment unencumbered and without time pressure. To get later on the wall a uniform structure, you should always apply only as much cleaning as can be processed within the open time (about 15 minutes depending on temperature and humidity). In related areas you should continuously wet-on-wet work, i the plaster is already being applied before the other layer is dried. The color scheme can be done by then recoating with emulsion paint.

First, the wall using the whisk must be mixed lump-free. mature briefly and then stir again. raise the plaster with a trowel and then customize at will. When using rollers track structure is rolled for rail with an even pressure through the fresh reared plaster. In free design any patterns are pressed by using various objects on the plaster surface, turned, rubbed etc. Creativity knows no bounds.

the fresh plaster surface is individually structured by crisscross, horizontal, vertical or round rubbing with a plastic smoothing or wood float. Mineral decorative plasters can be colored with standard solid colors and paint over. Some roll plasters can be applied with a paint roller and offer by coloring with pigments an easy, fast and versatile type of wall design.

Processing of cotton plaster and wall decals

Processing of cotton plaster and wall decals

Cotton plaster is ecologically and offers the ease of processing many more advantages. We explain step by step how it is applied and can be combined well with wall decals.

Processing of cotton plaster and wall decals

Apply Reibeputz

The processing of decorative textured plaster is much simpler than the application of a basic plaster. If you have mastered the essential handles - and that does not take long - then this task is not heavier than usual home improvement activities such as painting or wallpapering.

preparatory work

spackling flaw in the wallA decorative plaster can not compensate for holes, rough bumps and other imperfections. Therefore such damages must be previously closed with a repair putty.

First check the wall and fix problems with the strength, absorbency, flatness or damage - what to consider and how best to proceed, we have described above.

Now cover the area thoroughly with foil, regardless of whether you plastered outside or inside: plastering is quite a dirt-intensive work. Indoors, it makes sense to attach the cover with masking tape to the skirting boards, so they can not slip.

You can then treat to be plastered walls with plaster base. This is a pigmented primer that produces a uniformly colored surface. This is important because in structures formed by rubbing a grained plaster can shine through the color of the background. Many rendering bases also contain silica sand or similar blends that create a rough surface. Then the cleaning grain when rubbed rolls significantly better than on a smooth wall. In addition, the plaster base adheres to substrates such as wood, metal or plastic, so that can also include shutter boxes and similar elements in the plaster in this way.

The plaster base is coated on the surface with a roller or brush, at edges and corners with a brush. He then left to dry according to manufacturer's instructions. Since you usually are not exactly up to the light switch and renovating. zoom brush ä., you can now to such elements and to door frame sticking a strip of masking tape, which is removed after plastering.

Mix Reibeputz

Stir flush with agitatorcan be prepared by mixing the plaster with a drill and a mixing paddle. Which provides for the machine, however, a heavy burden. Better to get a special agitator ahead.

A mineral textured plaster is available as a dry ready-mix in the bag or bucket, which must be mixed with water before processing. Practically, when the ready-mix comes right down the drain, then you can use it to mix and always has a clean mixing vessel. Otherwise, use a mortar tub that you should clean before each new approach, because remnants of the previous approach can lead to lumping and premature, partial hardening of the plaster.

Mix water and dry mix according to manufacturer's instructions. For this purpose, is a drill with mixing paddle. Both the agitator and the machine must be robust enough, because the resistance during agitation can be substantial. When in doubt, save your drill and rent for tool hire an agitator, which is designed precisely for such tasks.

The attaching of subsets can be tricky, because when transporting the plaster ingredients may have been separated. Refrain better prepared or stir at least the dry mixture before removing a subset thoroughly dry through.

Put on more than the amount that can be used within the manufacturer's specified so-called "open time". Do not add a tinting pigment, if necessary. Let then mature for a few minutes the plaster according to manufacturer's instructions.

plastered wall with Reibeputz

Now it gets serious: First Name Use the stainless steel trowel a chunk of plaster from the bucket to the trowel and drag with inclined trowel from the bottom to the top of the wall. If you have raised 1 to 2 square meters, hold the trowel at a more acute angle to the wall and pull the plaster sharply across the grain contained from.

You almost automatically achieve a uniform layer thickness: She is always determined by the cleaning grain. If you are working with multiple people, you can divide the individual steps with each other and are significantly faster progress.

take plaster from the bucketThe mature plaster is taken with a ladle of em bucket and are then wages of a trowel. Be sure to use only tools of stainless steel.Apply the plaster on the wall deiWith inclined trowel of Reibeputz is drawn from bottom to top of the wall. Then pulling it sharply across the grain.

structure Reibeputz

If the plaster attracts, so an initial set, its surface becomes dull. This is the starting signal for patterning. For this purpose, edited Reibeputz with a plastic float which has a slightly rough surface. The float move it flat over the wall with light pressure. By this movement, containing grit rolls through the plaster, leaving behind cavities.

The type of movement thus determines the plaster structure. You can work with large circular motions, rub or only vertically, horizontally or diagonally crosswise. Important: Even if you plaster of two or three, should rub only one of you in the same room or at least on the same wall. Everyone finds it its own rhythm, and it shows as an individual "signature" of the plaster structure also. After rubbing possibly attached masking tapes should be deducted before the plaster hardens completely.

Incidentally, lubricates the plaster when rubbed, then is probably still too much of it on the wall. In this case, you should pull off again sharply with the trowel across the grain to remove excess material.

Here's how: movement creates structure

By rubbing with the plastic trowel, more precisely, by the rubbing direction, determine the subsequent Aussehen.Je after rubbing direction arises another decorative pattern.

Tips for working with textured plaster

  • Only use tools made of stainless steel, otherwise the danger is too great that Kellen and smoother rust and leave stains in the plaster.
  • Clean used tool before breaks and at the end, rinse immediately with clean water. Later, the cleaning is virtually impossible to remove.
  • Work especially if you have scratches or other fresh injuries on the hands with gloves. The fresh plaster can be very aggressive here.
  • If you stop working before a break or at the end of the day, you should have an unfinished wall plastered ready always to the next corner of the room or the next interruption by a projection or a niche. Plaster must be applied on the surface always fresh to fresh - the previous section is dry already (to), you can see the approach later inevitably.
  • If you guzzle the first time or are a while out of practice, you start to work in a place to which one does not see at first when entering the room. The area behind the door is suitable for mostly very good.

Roll cleaning process

Who exercise in painting with the government should transform used little if he wants to apply roll plaster. However, unlike ordinary wall paint then stand here open numerous possibilities for designing the surface. More on that in the following instructions.

Materials and tools

  • Putzgrund
  • roll Putz
  • Possibly. Pigments for tinting
  • Possibly. Repair Putty
  • Paint rollers for applying
  • grates
  • Tools for structuring how finish roller, brush, trowel, sponge or brush
  • cover
  • masking tape
  • Drill and mixing paddle

preparatory work

Roll cleaning, apply on tilesDepending on the product, you can even paint over tiles with Roll plaster. Here's diligent work so particularly important: The joints must be completely ausgespachtelt, an adhesion-promoting primer ensures that the plaster keeps properly.

As described above, first check the ground for defects on its suction and capacity and treat him accordingly as needed.

Now Cover the floor and in the space remaining furniture with foil. So that the film does not slip, fix them most about the baseboards with masking tape. Also, door and window frames must of course be taped. Sockets and switch covers take off best - before turning off the power and have them implemented by an electrician working on the electrical installation at the slightest uncertainty!

Now swipe against the surfaces to be plastered with plaster base. It makes for a uniform adhesion of the plaster, compensates for different absorbency and creates a uniform color surface.

Apply the plaster base on larger areas with the role, on the edges of use a brush. Let the plaster base, then according to the manufacturer dry. Usually sufficient for a few hours.

Apply Roll Putz

Roll Putz to get ready in the bucket. Since individual components fall in the storage on the bottom of the bucket, others rise to the surface, the cleaning before use must be stirred thoroughly again. In return, a drill with mixing paddle is good, running at low speed.

On this occasion, you can also color the rolling plaster. Use only part of the system pigments from the same manufacturer or tinting colors that are recommended by the manufacturer of the plaster. Mix long and hard until a completely homogeneous mass has formed colored and uncolored find any cleaning amounts more in the bucket are - especially on the walls of the bucket along this danger.

Roll the plaster, you can now apply as a more viscous wall paint. Moisten the role at the beginning slightly and take roll plaster from the bucket. Roll then fed the plaster as the painting briefly about one grates and bring and evenly on the wall.

Be sure to always work wet-on-wet and apply the plaster evenly as possible pace and even thickness. Brush the roll on the wall is not completely dry, but take time again new plaster. Before you take a break, you should always work to the next wall boundary, so that one sees no later approach.

Apply Roll Putzthe plaster can be easily rolled up to the prepared wall. For corners and edges take a brush.Apply roll plaster for twoIf you work in pairs, one person can continue to apply the plaster, while the other already structured.

Edit Roll flush-surface

After applying the plaster surface looks rather rough. If you like rustic, it can be like that. If not, however, lend themselves to numerous possibilities to design the structure according to your taste. The simplest method is to revise the surface with a matching finish role. Here, you can hardly go wrong and there is a finer plaster structure.

Other possibilities brush, brushes or sponges. Even with a plastic spatula, the plastered surfaces can be processed. Use caution to work, because the rolling plaster layer is thinner than traditional decorative plaster, which can be quite safely structure with bold trowel momentum.

Are you unsure how the surface works best, just try different techniques previously made on a large board to which you apply a coat of plaster roll.

Roll cleaning structure with the finishing rollerIn the simplest case, you roll over the plaster just finish with a roller that there is the manufacturer of the roll plaster. This results in a uniform fine surface.structuring roll cleaning with a brushCreative is it when you bring a tool of your choice here with a flat brush, structures according to your personal taste.

Tip: Roll plaster applied on wallpaper

You can also apply to an existing wallpaper roll plaster. This renovating falls easily later if you want to make your walls from scratch again. However, the wallpaper musss be it moisture-resistant adhesive. You can test this by moisten them with a wet sponge in several places. Raises the wallpaper here after a few minutes of exposure bubbles, then it is not suitable as a cleaner surface.

Mineral plaster or synthetic resin plaster?

Whether you prefer synthetic resin renders or mineral rolling or rubbing plaster depends on whether you prefer a crack-bridging properties and the readiness for use of plastic plaster, or if you put more emphasis on higher breathability and a natural indoor climate of mineral plaster.

Plasters mineral based contain lime and cement and are therefore less sensitive to mold. In addition, the moisture penetrates through and is discharged outside. Therefore, the variety of spaces is high humidity. Whichever you choose, the processing (except for the attaching) is no different. 

However, you should wear gloves during processing, as this plaster can due to its alkalinity cause irritation. He is also difficult to apply than the relatively user-friendly Synthetic resin plaster. This also includes lime and cement, but is partly made artificial resins, so-called. Polyester resins. With its ease of processing it is suitable for home improvement without extensive previous experience in dealing with plaster.

Synthetic resin renders are indeed mostly available as white plaster, but can easily with high quality emulsion paints in all desired colors simply painted or dyed directly with color pastes. High-quality synthetic plasters are very durable. With a grain size between one and five millimeters they allow, regardless of the overpainting almost unlimited design possibilities. The smaller the particle, the finer the structure. By the respective grain size to the film thickness defined in the application.

Synthetic resin plasters are suitable for indoor as well as outdoor use and convince with crack-bridging properties and use skill. From the fireplace apron, a balcony walls up to the front or to the living room wall all surfaces can be plastered so tasty - at an attractive price. The plastic plaster can be processed as a scratch coat, textured plaster, pitted, spray plaster, plaster roll, Buntsteinputz or free-style.

High-quality synthetic plasters are permeable, so water vapor permeable. The wall is breathable, humidity can be absorbed and released again. The result is an ideal indoor climate. Prerequisite for a perfect result when working with synthetic resin renders besides some craftsmanship preparing the walls, such as with primer. It makes the surface grip and reliably prevents slipping of the plaster.

The latest generation of synthetic resin plasters can be solved from the wall again without any problems. Simply spray with water and remove without leaving any residue after five minutes. So are plastered interior walls in apartments no problem if the apartment must be passed renovated in the exodus.

Thin plaster and putty plasters

thin plasters arrived in recent decades by changes in the design. Exactly sized plane, level stones, bonded with thin-bed mortar, or even concrete prefabricated elements do not require thick, uneven balancing layer of plaster more. A thin plaster is mainly used for optimization of the surface quality and is applied in only one layer.

Even thinner is to use the smoothing plaster. This mineral material can be extended even to zero. String plasters are fine-grained, are thinly applied with a paint brush and then patterned with a brush or brush. Roll as plasters have a fine marble grain and maintain their structure through the respective the brush, trowel or a machining with rollers or rolls.

The dry mortar based on gypsum is sprinkled into clean water and stirred to form a homogeneous, plastic mass. After mixing, the mortar is fired up with a trowel or mounted with the Aufziehbrett, wherein a strong pressing against the plaster base for the full-surface adhesion is required.

Then, the plaster is leveled with a smoothing board or grapeshot and perpendicular and aligned distributed. With the onset of stiffening the cleaning surface may be coated with the grapeshot and the trowel to remove marks and grades. then the plaster sufficiently stiffened, it is easily angenässt, felted with the sponge float and then smoothed with a trowel.

For the exhaustion of the corners using a Eckspachtel or Eckhobel. If a felt structure will be created, nachgefilzt the surface structure with a fine sponge float again after felting and a certain service life. When a mineral decorative plaster or ceramic tiles to be applied to the plaster, the surface may not be felted or smoothed. It is only withdrawn with the Traufelrücken to get a firmer and rougher surface structure. When mixing and applying plaster for thin plaster is analogous to manual cleaning.

professional advice

Remove immediately after plastering the tapes again. The still soft plaster dissolves easily and the tape leaves the desired exact (possibly different color) line.

to remove plaster walls takes time unnecessarily. Who inking the plaster before application works not only faster, but also gets a better result. The finished surface is much less susceptible to shock and damage, because with solid-colored plaster little quirks are not visible as white spots.

Plaster manufacturers offer slightly soluble granules color, opaque their renders. The flush-tinting paints or pigments can be easily dosed are light-fast, smudge-proof and suitable for indoor and outdoor.
