This matt varnish is really dull. This sets him apart from the many semi-gloss products on the paint market. I have thus painted a 50 sqm wooden ceiling which was very yellow. Actually, I originally wanted to remove the wooden ceiling and replace it with a plasterboard ceiling. Only, I've seen some DIY ceilings that are not really attached well, the shocks simply shine through etc .. So I have changed my mind, and painted the ceiling. The visual impression is almost a painted with white latex paint ceiling. However, I had 3x emphasize in order to achieve a truly comprehensive surface. The edge coverage is great, the course is uniform. I could dilute the paint a little, especially when job role well. Only when processing there is a slight smell of paint, which is then already after 2-3 hours away. Disadvantage without penalty: the price ... :-)). The paint is better than cheap products from the hardware store or discount store. I suspect that the paint not so quickly changed in color (yellowing).
