How to use

PRIMING

Apply Polyprime SB (Solvent based primer) @ 4-6 m²/L by brush, roller or spray. Allow the primer to dry prior to the application of the membrane.
Easyfelt P4160 membranes are installed by using a cylinder fed propane gas torch. Heat is applied to both the roll and the exposed laps of the membrane being overlapped onto. Caution: Do not over torch the membrane as this will expose the reinforcement and cause damage to it.

TORCHING

Easyfelt P4160 membranes are installed by using a cylinder fed propane gas torch. Heat is applied to both the roll and the exposed laps of the membrane being overlapped onto. Caution: Do not over torch the membrane as this will expose the reinforcement and cause damage to it. 

UP STAND

An appropriate flashing membrane (Bituplus G) shall be lapped with the base membrane and taken up on the parapet wall and tucked into a groove cut into the concrete. The grooves will be sealed with a suitable mastic (Bitumastic).
