Polyguard's Water Based Activator™ is a custom formulation designed to increase the adhesion of our rubberized bitumen membranes in cool weather.

Being that our compounds are blended with high quality rubber and asphalt, they are effected by temperatures below 55°F. Like other products containing rubber and/or asphalt (tires, roads) they harden as temperatures decline. Our patented compound formula is no different, and during cold seasons, tack decreases with the temperature.

Our Water Based Activator™ is a contact adhesive which allows contractors to apply the products down to 35°F (1.5°C) in colder climates.

Water Based Activator™ is roller applied to the substrate (brush applied to the laps) and allowed to 'tack', then the membrane can be installed per instructions. Water Based Activator™ stays tacky for hours, allowing contractors to apply the activator to the duct and piping substrate hours before the membrane is applied. Since this is a water based product, it does not 'flash off' and must evaporate to a tacky state; this requires more time, and is dependent on atmospheric conditions (humidity).

Water Based Activator™ is also used on the bottom of large ducts to enhance the adhesion of our membranes to the substrate prior to pinning. If working in an area where solvent based products are allowed, please see our SB Activator.
