Blocksil® HD

The original Blocksil with all its unique features. This is better used as a fleeced system when the substrate requires that little extra strength due to poor substrate conditions e.g: cracks, bridging and joints onto adjoining structures etc.

Can be over coated with all the products in the Blocksil Range. Preparation for this coating is to remove all lose flaking coating and rust. Does not have to be taken down to clean steel, will tolerate rusts, and can give up to 20 year corrosion resistance. 


Blocksil Ultra Protector reacts with the surface it is applied to and provides very high bonding strength on the surface. It generates a very thin, transparent coating with high impact strength that is resistant to alkali, corrosion and dirt.
