Sika-Trocal has launched a new spray-applied primer, which 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% and helping to significantly 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 roof 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.
S-Vap 5000E SA FR and Primer 610 are the latest high-quality, cost-effective additions to Sika Trocal’s exemplary roofing range.
