Solvent Based Bitumen Primer - fast dry-ing, solvent based low viscosity bitumen primer for bituminous waterproofing membrane

A solvent based bitumen primer prepares a surface before a bituminous membrane is installed. The solvent carries bitumen deep into the surface then evaporates quickly, leaving a thin bitumen film. That film gives the membrane something to bond to, which is a required step in most concrete waterproofing systems.

Priming stops the membrane from bonding to dust or loose surface material. Concrete is porous, so an unprimed slab absorbs adhesive unevenly and creates weak spots. A waterproofing primer binds and evens out the surface, so the finished membrane holds firmly across its whole area rather than in patches.

Yes. SmartCare Bitushield Primer SB 2 is suitable for concrete surfaces, terraces and other construction materials. Terrace waterproofing benefits most, as the slab faces heat and movement that put stress on the bond. The primer's low viscosity helps it soak in and grip the concrete properly.

Yes. It is fast drying, so the membrane can follow soon after priming, which helps on tight GCC programmes. The non-oxidised bitumen film resists breaking down over time. Cold application also means no heating equipment on site, making it practical for busy UAE projects where speed and safety both matter.

No. It is cold applied, so no heating is needed at any stage. The product is used as supplied on a clean, dry, sound surface. Avoiding hot work removes fire risk from the priming stage and lets the team start straight away without waiting for equipment to warm up.

The primer creates a bitumen rich layer on the concrete, so the membrane bonds to a compatible material instead of a dusty mineral surface. Low viscosity allows it to enter fine pores and lock into the substrate. The result is a stronger, more uniform membrane to concrete bond across the area.

A bitumen primer is a preparation coat, while a bituminous waterproofing membrane is the waterproofing layer itself. The primer is thin, quick drying and cannot stop water on its own. The membrane is thick and reinforced. In a correct system the primer goes down first, then the membrane follows.

SmartCare Bitushield Primer SB 2 is a fast drying, solvent based, low viscosity, non-oxidised bitumen primer for bituminous waterproofing membranes. It is cold applied and improves adhesion between concrete and bitumen based membranes. Use it on concrete surfaces, terraces and other construction materials as part of a GCC waterproofing system
