Caltech LOW (Low Odour)

Caltech Warm Roof


CaltechLOW is a one component, cold-applied, solvent and isocyanate free liquid roof waterproofing system based on silane terminated polymers. It cures to form a seamless and durable waterproofing solution for exposed roof areas and structures.

Ideal for projects in more sensitive areas such as hospitals and schools due to the low odour properties the system has.

Key Features & Applications

low odour cold applied waterproofing system

  • For roof waterproofing solutions in both new construction and refurbishment projects.
  • For roofs displaying complex detail areas, even when accessibility is limited. 
  • For cost efficient life cycle extension of failing roofs. Applications scenarios sensitive to chemical handling and odour concerns.

Characteristics and Advantages

  • CaltechLOW is a single component product that requires no mixing therefore is easy to use and ready immediately.
  • Fully Cold-applied so requires no heat or flame.
  • CaltechLOW is solvent and isocyanate free, non-toxic and VOC compliant - providing a low odorous solution.
  • Provides excellent adhesion to most substrates (see table within product datasheets).

Application Details

  • When prepearing substrate the surface must be sound, of sufficient strength, clean, dry and free of dirt, oil or grease.
  • Dependant on the substrate the area must be primed.
  • Correct primer must be used on the relevant substrate (see product datasheet)
  • Once primer has cured CaltechLOW is applied along with the F-Mat reinforcement Fleece.
  • Apply further coat of CaltechLOW over the F-Mat. Caltech LOW is a wet on wet system.

Quick Tip

Benefits of LOW?

CaltechLOW contains no
toxic components or
isocyanates therefore providing a low odorous solution to certain projects that may be sensitive such as near or around operating theatres or primary schools for example. The wet on wet application also allows for a speedy and efficiant installation.
