FAQ

Yes, generally speaking, plastering is cheaper per square meter for larger surfaces. Plasterers can work faster on larger surfaces without much setup and dismantling time. This results in less time spent on installation, cleaning, and minor finishing touches, resulting in lower labor costs per square meter.

Sauce-ready This means the wall is neatly finished and ready for painting. Small imperfections or slight undulations are permitted and may become visible in bright light or spotlights. This finish is particularly suitable for light colors and is the most economical option.

Smooth plasterwork This is a smoother, more luxurious finish. The walls or ceilings are made extra smooth, making imperfections virtually invisible. This type of plasterwork is ideal for low light, large windows, or dark paint colors and ensures a perfectly smooth finish.

Spachtelputz is a commonly used decorative plaster for interior walls. It consists of synthetic resin and fine stones (usually 1–2 mm), which creates a light grain texture. It is applied wet and then hardens to a strong, durable finish. Spachtelputz is a good choice if you want a smooth, but not completely smooth, wall. It requires little maintenance and is a durable finish that will last for years.

The drying time for plaster is approximately one day per millimeter of layer thickness. In most cases, the plaster is sufficiently dry to paint or wallpaper after 7 to 14 days, provided the room is well ventilated and the temperature is normal.

Plastering a house takes an average of 1 to 5 business days, depending on the size of the house, the condition of the substrate, and the type of plastering. An apartment or terraced house is often finished within 1–2 days, while a larger house or a completely new build can take 3–5 days.

Old plaster doesn't always need to be removed. If the existing plaster is secure, doesn't sound hollow, and has no cracks or loose patches, plastering over it is usually straightforward. If the plaster is damaged, loose, or damp, it may need to be partially or completely removed to ensure proper adhesion and a smooth finish.

For new plasterwork, use paint suitable for freshly plastered, slightly porous surfaces. Always wait until the plaster is completely dry (usually 7–14 days) before painting, and apply a primer for a smooth finish. The most common option for interior walls is acrylic latex wall paint.

No, plaster doesn't always need to be painted. Smooth plaster can also be left untreated, but it will then be more susceptible to stains and moisture. In most cases, plaster is painted anyway, because paint provides protection, an even color, and easier maintenance. With decorative plasters like spachtelputz, painting is often unnecessary because they are already applied in the desired color.

Plasterwork is somewhat resistant to moisture, but not completely waterproof. In dry areas like living rooms and bedrooms, this isn't a problem. In damp areas (bathrooms, toilets, or kitchens), it's important to let the plaster dry thoroughly and finish it with a moisture-resistant paint or coating. For areas with direct water contact, such as showers, standard plasterwork isn't suitable, and tiles or a special waterproof finish are better.

Properly applied plaster lasts an average of 20 to 30 years. Its lifespan depends on the quality of the plaster, the substrate, and how well it is maintained. In dry areas, plaster often remains good for decades, while moisture, cracking, or a poor substrate can shorten its lifespan. Regular painting and timely repair of minor damage significantly extends its lifespan.

Yes, plaster can be susceptible to cracking, especially due to substrate movement, temperature fluctuations, or excessively rapid drying. This is more common in new-build homes or at transitions between different materials. With proper preparation, such as applying reinforcement mesh, good ventilation, and sufficient drying time, the risk of cracking can be significantly reduced.

Yes, make sure the space is empty and clean, electrical outlets are clear, and any loose paint or wallpaper is removed so the plasterer can start work straight away.
