New product 'virtually odourless and solvent-free'

Preston, UK-based Sika Liquid Plastics, specialised in cold-applied liquid roofing membranes, has expanded its Sikalastic range with the addition of Sikalastic STP, which it claims to be a “virtually odourless, solvent-free and rapid cure wet-on-wet system.”

Based on Sika patented technology originally formulated for the sealants market by Sika’s chemists in Zurich, the solvent-free formulation was developed and refined by Sika Liquid Plastics’ UK R&D team in Preston. 

“The result is a high performance cold-applied liquid roofing membrane that provides virtually odourless application and proven high performance,” Sika Liquid Plastics said 29 Jan.

Sikalastic STP is based on a hybrid technology that is solvent-free and can be used for both new build and refurbishment projects, including overlay installations.

The cold-applied liquid membrane is rollered onto the prepared substrate and a polyester fleece membrane is laid onto the wet membrane, with further liquid Sikalastic STP applied onto the wet reinforcement fleece before the membrane is allowed to cure.

“Once fully cured, it forms a high performance, seamless and elastomeric waterproofing membrane that is fully-bonded to the substrate,” the company added.
