A liquid roofing and waterproofing system, which was the first of its kind to be launched in the UK, has turned 20.

KEMPEROL 2K-PUR, which is manufactured by Kemper System, has retained its unique market position over the last two decades. It remains the only cold liquid-applied wet-on-wet waterproofing product in the UK which is sustainably sourced, solvent-free and completely odourless.

Manufactured using an 80 per cent castor-oil formula derived from sustainable sources, the liquid system bonds directly to the substrate forming a seamless, elastomeric waterproof membrane that cannot delaminate and is UV stable.

Stuart Hicks from Kemper System said:

“The 20th anniversary of Kemperol 2K-PUR is a major milestone and demonstrates our forward thinking commitment to innovation, quality and sustainability.

“The system has stood the test of time with a proven 20-year track record and continues to be one of the most popular and sought-after systems for all sorts of projects. Its unique qualities make it ideal for waterproofing buildings where environmental considerations are a priority or for occupied properties when the work has to be carried out without disruption from strong odours.”

Kemperol 2K-PUR is applied using a reinforcement fleece, which has recently been upgraded by Kemper System. The new fleece is perforated as part of the production process rather than needle punched post manufacture. This makes it stronger and greatly reduces the formation of air bubbles under the fleece allowing the resin to saturate the fleece more quickly and improving the speed of application.

“As the liquid waterproofing industry continues to grow, it is vital that we keep innovating and providing the highest quality products to meet our customers’ demands,” continued Stuart. “The launch of the new time-saving fleece keeps Kemperol 2K-PUR ahead of the game and is another major benefit for roofing contractors. Its design enables them to apply the liquid resin very quickly and easily, helping them to work even more efficiently.”
