Remove dirt, grease, curing residues and coatings that block absorption. Leave the concrete clean, dry and absorbent; check uniform wetting with a light water spray.

Mix 1 part Salt Hard+ with 4 parts C² Hard or C² Super Hard, not water. Stir before and during use and apply within 24 hours. Work at 4–35°C and keep the surface above 4°C for 8 hours afterwards.

On horizontal concrete apply one coat that remains wet for a few minutes; broom out puddles. On very porous concrete apply a lighter second coat 5–10 minutes after the first has penetrated. Dense surfaces need one coat; remove excess.

Touch-dry in about 1 hour. Protect from rain for at least 6 hours and traffic for 24 hours. Water repellency continues to develop for up to 14 days.

Clean tools with fresh water before the product dries. Immediately wash splashes off glass, aluminium and other adjacent surfaces.
