Properties:
Combiflex PK is High performance cold applied single component waterproong membrane, specially designed from a blend of special resin and rubber, reinforced with special water repelling fillers, minerals stabilizers and gelling agent. Combiflex PK can be applied over several types of substrates as waterproong and protective coating for concrete and masonry.
Areas of Application:
- Suitable for waterproofing and protection for wet areas, kitchens and substructures.
- Vapor barrier coating for walls and floor.
- Waterproofing system for shaded or tiled roofs.
- Waterproofing for polyurethane foam slab.
- Waterproofing for polyester built up roofs.
- Maintenance of existing roofs, masonry and concrete walls.
Advantage:
- Single component, easy to apply, no need for mixing or heating; saved labor costs.
- Elastomeric bridge minor cracks which may occur in concrete substrate.
- High tensile strength and elongation.
- Excellent adhesion to substrate.
- Highly elastic product and cures to rubber like membrane.
- Can withstand severe causes of expansion, contraction and deck movements.
- Highly resistant to oxidation, UV light and ozone.
- Non-cracking.
- Resistance to peeling, chipping and/or separation and longer life.

No need for primer coat prior to applying the Combiflex PK
No need for primer coat prior to applying the Combiflex PK. If needed, and in case of dusty surface, a prime coat can be applied by diluting 75% Combiflex PK & 25% water and applying a prime coat. Wait for the coat to dry prior to application. Apply two coats at rate of 0.8-1 kg/ m2 to provide a total thickness of minimum 1.5 mm. Stir the contents of drum thoroughly to remove all sediments. Apply material to achieve required thickness at an interval of 24 hours at room temperature. At joints and detailing, apply a layer of mesh reinforcement while the first coat is wet. If needed you can apply the mesh reinforcement all over the application area. Allow 24 hours for curing.
