Low Odour Liquid Applied Roof Membranes

One of the main challenges facing the use of solvent based liquid applied waterproofing, in various refurbishment situations, still relates to the odour emitted during and for a period after application, which is a result of the product’s drying and curing processes. This posed a significant product development challenge, to achieve a successful outcome without compromising other aspects, such as how the products handle on site or what reinforcement can be used.

Through careful engineering and true innovation, Sika have developed low odour systems using patented technology to enable use on highly sensitive sites, such as hospitals, food manufacturing plants and schools.

Sika research and development

Decothane Ultra

Sika have been manufacturing high performance protection and waterproofing systems for over 50 years. In that time, our pioneering research and development has ensured continual advancements in the technology and production of Decothane Ultra, our flagship product.

Through our history, these product advancements to Decothane have been customer focused and driven to meet market demands. Decothane Ultra is a high performance, polyurethane coatings, which rapidly become resistant to rain damage, is cold-applied and cures to form a completely seamless waterproof membrane. These product benefits have enabled liquid waterproofing to become the fastest growing sector of the flat roofing market.

Decothane Ultra establishes a new benchmark amongst single pack polyurethanes and presents opportunities for architects, specifiers and contractors, to use liquid waterproofing within these niche and specialised markets.

Decothane Ultra Basecoat

Decothane Ultra Basecoat is a 1-part, low odour, cold-applied, elastic, polyurethane base coat. It incorporates Sika's unique i-Cure technology. The introduction of this brings several important benefits, including:

  • Lower embedment rates, at 1 l/m2
  • Ease of application (year-round), even at lower temperatures
  • Faster break-down of Reemat glass fibre matting
  • Faster cure
  • On smaller sites, there is the possibility for same day overcoating
