Surface Preparation
Clean the substrate thoroughly to remove dust, oil, grease, and loose particles. Repair any cracks or voids for a smooth and uniform surface.

Priming
Apply a compatible bituminous primer (0.3-0.4 liters per square meter) evenly using a brush, roller, or spray. Allow the primer to dry completely before membrane application.

Membrane Installation

• Unroll roofing felt and align it on the primed surface.
• Heat the underside of the membrane using a gas torch until it becomes tacky.
• Press the membrane firmly onto the substrate and smooth out air pockets.
• Overlap adjacent sheets by at least 75 mm on the sides and 100 mm at the ends to ensure proper sealing.

Corners and Details
Pay special attention to edges, corners, and penetrations by reinforcing with additional membrane layers or sealing tape for a watertight finish.

Finishing
For exposed areas, apply a reflective coating like aluminum paint to enhance UV resistance. For trafficable areas, overlay with tiles or a concrete screed for added protection.

Precautions

• Avoid overheating the membrane during torching to prevent damage.
• Work in well-ventilated areas to minimize exposure to fumes.
• Use appropriate personal protective equipment, including gloves and goggles.
• Store the product in a vertical position, away from direct sunlight or heat.
• Follow the manufacturer's application guidelines for optimal performance.
