Jotun Mur Acrylic Topcoat is a silk matt, very weather and alkali resistant water borne acrylic paint for masonry with a very good adhesion. It contains fungicides to combat surface fungi (black spots). Jotun Mur Acrylic Topcoat is recommended on untreated or previously painted masonry outdoors (not on lime rich plaster), and it is particularly well suited for concrete. It is also recommended for cement based building boards (not Supereternit), that are primed with Jotun Mur Acrylic Primer. Bricks must be plastered before painting.
