How to use SBS Modified Bitumen Waterproof Membrane

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.
