• Prevents discolouration & flaking caused by salt, metals and frost.
• Prevents the penetration of adhesives / silicone with slabs 
• Makes cleaning easier 
• Protection for subsequent work, such as painter, carpenter, etc. Does not replace the need of covering against mechanical damage! The drying time is approx. 1 hour. The curing time is 24 hours. 

Can be diluted 1:3 with water. 1 litre is sufficient for up to 50 m², on all sides 20 m², depending on the absorbing properties of the sub-surface.
