While in earlier years the Raspasertapete still belonged to the standard in the flat, this is replaced more and more by the rolling plaster. You do not have to be fidgety when applying roller coats, it is suitable for the walls as well as for the ceiling of any room and can be provided with attractive structures.
Rolling plaster also applicable indoors
Contrary to widespread views, plaster is not only something for exterior walls, but also brings out interiors very well. The plastering of walls and ceilings inside is not difficult, because the rolling plaster can be applied just as easily as you paint with paint. Even with wallpaper as a substrate, it is often possible to apply plaster, but this depends on the condition of the wallpaper. With a prior check of the substrates, it is easily possible for you in home work to beautify your walls and ceilings with plaster and to paint this independently. The plaster does not have to remain in its original color, you can apply it with tinting in the desired color or later paint over with emulsion paint.
Material and preparation
You need this:
- sufficient amount of roller trim
- Roll or puff brush to apply
- Primer for walls
- Putty and spatula
- narrow brush for corners
- Electric drill with whisk
- masking tape
- Telescopic handle for paint roller
- Scraper for paint roller
- Roll for primer
- Brush for primer
- Tinting color if required
- Vat for color if required
- in case of structural request: brush, pea-roll, sponge
- Brush for the wall
Before you can start painting, you must prepare the room accordingly. Remove all pieces of furniture from the wall and bring them to the middle of the room or out of the room. Carefully cover all furniture still in the room with masking foil and glue it to the painter's crepe. Remove the frames from sockets and light switches and glue them off as well. Windowsills, door frames, ceiling lamps and strips, as well as the floor when painting the ceiling must also be covered. Before you can apply the primer, the wall must be free of dust and debris. To do this, brush vigorously with a hand brush over all surfaces.
The preparation of wall and ceiling
Before you can start applying rolling plaster, you must ensure a firm, level surface. Wallpapers can be overcoated with roller coats if they are absorbent and sticky. With a simple test you can check the wallpapers for their quality. Use a sponge to apply water to some areas of the wallpaper and wait a few hours. If the wallpaper begins to ripple, remove it completely because it is unsuitable as a base. If the wallpaper remains in its original form, you can start applying the rolling plaster.
Tip: Wallpapers should be painted over once with roller plaster. If there is already a layer, remove the wallpaper.
For walls without wallpaper, it is important to level them first. Drill holes, dowels or hackers in walls and ceilings must be filled with putty before you can paint over them. Stir the putty according to the instructions and pour quickly into existing holes. Be sure to smooth out excess putty with a spatula to leave a flat, paintable wall. It must take at least two hours, so that the filler can dry. Existing nails of pictures or dowels of other fixtures must be pulled out of the wall prior to processing the putty.
In order to be able to apply the roller plaster evenly, priming is required in most cases. For this, a "plaster base" or "quartz ground" is best suited. First apply the brush to the primer at the corners and edges of the room and then prime the walls and ceiling with a roller. Apply the plaster base comprehensively and generously to provide a stable surface. A layer of primer is sufficient, only with heavily soiled walls by nicotine a second coat may be required. The drying time of Putzgrund is on average six hours, but may vary slightly by the ambient temperature. Check at an invisible location if the plaster base has already dried completely.
Tip: In very cold rooms, it is advisable to install a fan heater to speed up the drying time.
Apply rolling plaster
Prepare rolling plaster for use
Before starting work, make sure that you have sufficient rolling plaster available. Should your material run out in the meantime, there could be structural differences on the wall and ceiling. If you use tinting paint, you need to place the rolling plaster in a large vessel (tub), so that you achieve a uniform coloration of the entire material. If you would mix later color again the danger would be great that you will not achieve the same color result and there will be differences on the wall. The rolling plaster must be creamy and stirrable before you can apply it. Put the agitator on the drill and stir the plaster for a few minutes on slow speed. Only when the rolling plaster has achieved a noticeable consistency, it is suitable for painting the walls.
First, paint corners and edges
If you want to paint not only the walls, but also the ceiling, this comes first. This is important as otherwise the walls could be dripped later. To completely cover the corners with plaster, paint them with a brush / puff. When applying, ensure a uniform thickness of the layer and distribute the rolling plaster quickly. Roller shutter boxes or sockets and light switches that are embedded in the wall are also painted over with a brush so that you can achieve a flush result.
Tip: To paint the corners, a paint tray is recommended in which you pour the required amount of roll plaster and are thus more flexible.
Paint the ceiling with roller finery
Depending on the room height, you may need a telescopic handle in order to be able to apply the ceiling inside with roller plaster. Screw this onto your roll and lay the scraper ready. Before the first ink pickup, moisten the roll well and wring excess water. Carefully dip the roller in the paint and make sure it is evenly covered with the material. Wipe off any excess plaster on the scraping grid before you start painting. In the distribution of the rolling plaster, the so-called cross technique is used. Swiftly roll the roller horizontally, then vertically along the ceiling and work from side to side. By using the crosswise application technique, no visible application edges are created, but a uniform, even result. Paint the ceiling in one operation and do not interrupt your work, otherwise structural differences may occur. Make sure that you use the same amount of roller plaster everywhere and that you do not have any thicker or thinner areas left over.
Paint the walls with roller plaster
After the ceiling has been painted, the rolling plaster is applied to the walls. Pick a wall face to start with. Spread the rolling plaster from top to bottom, using the cross technique as much as possible. To avoid structural differences, you should always finish the wall before you take a break. When you move to the next wall, you can take a short break, but it should not take more than 15 minutes. Make sure that the plaster is applied evenly in all places, usually a coat is sufficient as the wall has been optimally prepared by the previous primer.
Structural ornaments with rolling plaster
Roll plaster is ideal for decoration with structures. If you so desire, you can not spend more than ten minutes between the application and the decoration, otherwise the rolling plaster will have become too firm. You can bring in structure with sponges, brushes or even a pea-hole roller. So that the structure is even, do not work in the Kreuztechnik, but drive the wall in layers from top to bottom (pea-hole roller). For somewhat uneven structures, you can use the brush or a sponge pattern in the plaster at your leisure. Also, color effects can be achieved with paints and paint in retrospect. For the application of paint, however, the plaster must first be completely dried.
