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.
APP Modified Bitumen Membraneis installation process involves surface preparation, priming, cutting and positioning, heating and bonding, sealing, and the installation of a protective layer. Careful attention to each step is necessary to ensure a high-quality and long-lasting waterproofing system.
