Application advice
Proper substrate preparation is essential for achieving a uniform ultra-matt finish. New plaster or plasterboard surfaces must be dust-free and completely dry. Any repairs should be made with suitable fillers, then finely sanded. On older surfaces, clean and remove all traces of flaking or chalking before applying the paint.
Apply Dekso 1 Ultramat at a minimum temperature of 10°C and relative humidity below 80%. Work with a paint roller or spray gun depending on the surface area. The paint is touch-dry after 1 hour at 20°C and 60% relative humidity. Allow 4 hours between coats. The surface will reach its final hardness and resistance after 28 days of complete curing.
This paint to mix allows you to choose your colour from the Flügger 32 and Flügger 80 colour charts. Ensure you order the required quantity in a single tint to guarantee colour uniformity across the entire project. Available sizes: 0.75L, 3L and 10L.

Pro tips
The classic pitfall with an ultra-matte paint of this quality is underestimating the importance of consistent application. Unlike a satin finish that forgives minor cross-brushing defects, ultra-matte reveals even the slightest brush marks or poorly blended roller passes. Always work in complete zones and cross your strokes quickly without going over the paint once it starts to drag.
Another practical tip: for large wall surfaces, use a short-pile paint roller (5-6 mm) that minimizes texture and maximizes the velvety finish. And above all, never overload your roller. With a theoretical coverage of 8 m²/litre and abrasion resistance class 1, this paint applies in thin, even coats. This achieves an extra-robust surface that tolerates spot cleaning with mild detergents and a non-abrasive sponge, while maintaining its flawless matte appearance.
FAQ
How many coats do I need on fresh plaster?
On properly prepared and dusted fresh plaster, two coats of Dekso 1 Ultramat are generally sufficient for a uniform result. Allow 4 hours drying time between coats at 20°C. If the substrate is very porous, an appropriate primer may be recommended to optimise coverage.
Is the ultra-matte finish truly washable?
Yes, despite its ultra-matte finish, this paint offers wet abrasion resistance class 1 according to EN 13300 standard. It tolerates spot cleaning with water, a mild non-abrasive detergent and a soft sponge or brush. However, avoid intense rubbing which could create local gloss marks.
Can I tint this paint in any colour I want?
Dekso 1 Ultramat is a tintable base compatible with Flügger 32 and Flügger 80 colour charts. At Pygmalion, we mix your chosen colour directly in store. Order the total quantity needed in one go to guarantee perfect colour consistency across your entire project.
Is this paint suitable for ceilings?
Absolutely. Its 100% acrylic formulation and ultra-matte finish make it an excellent choice for ceilings. The non-reflective finish masks minor imperfections and avoids unsightly light effects. Its H10 coverage class reduces the number of coats needed, even on lighter backgrounds.
How long should I wait before cleaning the painted walls?
The paint reaches full hardness and final abrasion resistance after 28 days complete drying at 20°C and 60% relative humidity. It is advisable to wait this period before intensive cleaning. For light spot cleaning, you may intervene earlier with caution.
