With any specialist sealant and bonding application the preparation of the joint is as important, if not more so, than the correct application of the sealant itself. 

Thorough cleaning of surfaces is essential for the reliable bonding of certain Sika adhesives and sealants. Therefore, Sika supplies special products with optimised adhesion to a wide variety of materials. Our range includes activators and primers for porous and non-porous substrates for all your sealant applicator needs.
