Acrypol TS Humidity Primer 18kg

Moist surfaces are troublesome when treated with any synthetic resin, both because of immediate adhesion difficulties and problems arising afterwards because of the upward water pressure. In many cases, material and time constraints force applicators to work on less-than-optimal support conditions, and a moisture-addressed product is needed in order to:


- Minimize adhesion failures.

-Avoid blistering due to the water pressure from below (support saturation)

-Avoid air bubbles, due to the water vapour pressure which cannot be released (mostly encountered inelastic membrane treatments.

-Incompatibility of the support with one-component, moisture-cured polyurethane resins.


TS Humidity Primer is the best solution as a primer for waterproofing or flooring polyurethane application on supports with moisture content greater than 4%.


Nevertheless, this product is not useful when moisture has a freatic origin, with pressures greater than 1,5 N/mm2. TS Humidity Primer is a 2-component, water-based epoxy resin. Components, once mixed, are totally compatible with moist supports, and the resulting polymerized product is a crystalline material with high adhesion and tensile strength. It effectively blocks residual moisture flow and prevents blistering of the polyurethane coating applied on top.


This product is useful for any kind of waterproofing project, involving polyurethane sealing, such as:

-Roof and wall refurbishments.

-Waterproofing treatment of tanks and other water management facilities.

-Floorings in moisture-affected environments.
