Application : Brush,roller or spray. STIR THOROUGHLY BEFORE USE. Seal new or bare surfaces with a thinned first coat of Dulux Trade Evolve Matt (up to 1 part clean water to 5 parts paint). The normal finishing process is 2 full coats of Dulux Trade Evolve Matt but on previously painted surfaces in good condition where similar colours are used, 1 coat may be sufficient. For best colour consistency, purchase sufficient tinted paint for each job at one time from the same source.
