Sika-Trocal has launched a new spray-applied primer, which it says dries almost instantly, speeding-up the installation of Trocal’s S-Vap 5000E SA and the new S-Vap 4000E SA FR by up to 50% – helping to reduce time and costs on site.
Primer 610 has been specifically developed to attain superb bonding strength, whilst being quick and easy to apply. The primer comes in a 19.66kg pressurised canister that covers approximately 180m² to 200m². On average its price per metre costs as much to buy as Primer 600. However, its faster application and drying time makes Primer 610 cheaper to use.
The tooling includes a unique long-life rubber hose that requires virtually no flushing through. Its speedy application is enhanced by using two nozzles – one on the applicator gun and the other immersed in a solvent tin.
The pressurised canister significantly reduces waste as all of the adhesive is forced out of the canister. Once empty, it can be easily decommissioned by using a special punch to push in the valve.
S-Vap 4000E SA FR consists of a polymer modified bitumen with a glass-fibre mat reinforcement and an aluminium foil as top layer, its simple and quick installation is due to it being self-adhesive. Ideal for a range of substrates, it can be used as temporary waterproofing for up to four weeks during the construction phase until the Sika-Trocal roof system is required to be completed.
The Sika-Trocal Insulation is then mechanically attached through the S-Vap 4000E SA FR and the appropriate Sika-Trocal membrane finishes the system. S-Vap 4000E SA FR then acts as a high performance vapour control layer.
