Liquid Waterproofing Glass Coatings

Sika’s Decothane Clearglaze is an anti-shatter waterproof coating for glass and rooflights. This clear aliphatic, polycarbonate polyurethane glass coating forms an effective barrier to water penetration and the ingress of atmospheric chemicals. Its transparent finish renders it suitable for applications where it is desirable to retain the appearance of the underlying substrate.

Decothane Clearglaze is particularly suitable for protecting porous stone, decorative aggregate panels and brickwork against water penetration and subsequent frost damage. The cured membrane enhances natural substrate colours -producing a “wet look” finish.

It is also suitable for use as a waterproof coating over glazing and rooflights. Combining toughness with excellent adhesion, the coating provides an alternative to replacement of glazing and glazing bars (dependent on condition).
Decothane Clearglaze has moisture-triggered curing which means it does not foam when excess moisture is present. It has a ‘wet-look’ finish when applied to porous surfaces and does not discolour with age or prolonged UV exposure.
