Bostik CemenTech C1 Duo Crystallized Waterproofing Mortar 25Kg 

GZ Industrial Supplies is the Distributors of Bostik Adhesive Products in Nigeria. This Bostik CemenTech C1 Duo Crystallized Waterproofing Mortar is a cement based, one-component, brush consistency, light-red colored powder sealing slurry that is reinforced by polymeric additives, and used in the solution of problems arising from capillary effects. It is used in both positive and negative side of waterproofing of garages, terraces, foundations and basements. CemenTech C1 Duo creates crystals that don’t melt within water when it reacts with water and renders the concrete water-tight permanently upon penetration of these crystals into the capillary vessels of the concrete.

    After researching various waterproofing options for my outdoor deck, I decided to go with Bostik Cementech C1 Duo based on positive reviews, and I'm glad I did. It's been several months since I applied it, and my deck still looks as good as new. Even during heavy storms, there's no sign of water penetration. Definitely worth the investment.
