Directions for use

• Remove salt efflorescence, dust, loose parts and standing water from the surface
• Apply on a closed surface; if necessary fill holes and joints with a fast setting cement-based product or polyurethane foam
• Apply at substrate and ambient temperatures above 5°C
• Application on humid surfaces allowed, but remove standing water
• Do NOT add water or solvents
• Do NOT apply in full sunlight
• Do NOT apply during rain
• Apply in two layers (airless spray or roller); apply second layer after first has dried
