Application
Dilute according to substrate absorption and roll on with a wool roller; concrete can be coated neat. Two coats on highly absorbent substrates. Levelling can start once the surface is damp but free of standing liquid.
Substrate preparation
The substrate must be sound, flat, dry, clean and free of cracks, oil and release agents. Shot-blast loose or heavily laitance-covered surfaces; damp substrates need a moisture barrier first.
