How TO USE
Substrate Preparation:
All substrates must be sound, dry, free from grease, dirt, or other contaminants, and must be reasonably smooth.
Priming:
A layer of primer should be applied to the prepared surface. The primer helps to improve the adhesion between the membrane and the substrate.
Torching Equipment:
Fire safety is the most fundamental while applying bitumen membranes. The torch equipment must be in good working
condition and properly connected. Make sure there are no gas leakage and a sudden gush of fire.
Installation:
The bituminous waterproofing membranes are unfolded on the site and laid firmly on the surface slowly while torching its underlayer (torch layer).
Bonding:
The seams and edges of the membrane are sealed using the torch equipment or propane torch to melt the SBS-modified bitumen on the edges of the membrane.
This helps to create a continuous and waterproof surface.
Storage:
Membranes delivered to the site are to be stored in a covered area or be covered with a protective sheet until
required for installation. Rolls are to be stored vertically to prevent damage to the ends.
Cementitious waterproof coating is a breathable, seamless coating used to provide positive and negative side waterproofing protection on concrete and masonry surfaces. They prevent damage from water infiltration and resist mold and mildew.
