Absorbent mineral substrates like concrete:
Very porous: up to 20% with RUST-OLEUM 160 Thinner.
Normal porosity: 10% up to 30% with RUST-OLEUM 160 Thinner.
Power floated (slightly porous): 20% up to 40% with RUST-OLEUM 160 Thinner.
Brush: Use natural long bristles brushes.
Roller: Use medium pile, 12 mm, perlon or polyester rollers.For textured surfaces use long pile 14-18 mm rollers.
