Sika Liquid Plastics has expanded its successful Sikalastic range with the addition of Sikalastic STP; a virtually odourless, fast curing, wet-on-wet system.


Based on Sika patented technology originally formulated for the sealants market by Sika’s chemists in Zurich, the formulation has been 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.


Pete Hollingworth, Head of Sales at Sika Liquid Plastics explains: “We already have a very successful low odour solution with Decothane Ultra. Decothane is celebrating 30 years’ of innovation this year and Decothane Ultra’s virtually odourless application and high performance have made it a popular choice with specifiers, contractors and end users alike.“For some applications, a wet-on-wet system may be preferred and Sikalastic STP means that we can now offer a wider choice of low odour cold-applied liquid membranes to suit all preferences and site conditions.”


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

The system has been developed to help contractors minimise time on site, enabling fast track completion and single process installation, backed by Sika’s trusted technical support, robust guarantees and installed through Sika Liquid Plastics’ Contractor Network.

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. Due to the speed and ease of application, there is potential for one day application on smaller roofing products.

Pete adds: “At Sika Liquid Plastics, product development is an ongoing process, driven by the needs of specifiers, contractors, building occupiers and both our natural and built environment. Not only is it vitally important to develop innovative products, we must consider, faster, more efficient and user friendly products for our network of approved installers."


Alex Coward, Research and Development Manager at Sika Liquid Plastics comments: “Innovation is key to Sika's strategy and our global R&D presence means that we have our finger on the pulse of the very latest cutting-edge technologies. In Preston we have the Global Technology Centre for Liquid Applied Membranes and the combination of our coating expertise as well as collaboration and knowledge sharing with our Corporate R&D team in Zurich has allowed us to develop an exciting new product for the market. Sikalastic STP expands our range of products and adds something a bit different for our valued contractor network. We very much look forward to seeing it grow.”


Sika Liquid Plastics has a cold-applied liquid solution for every project, no matter the budget or complexity.
