Air Barriers Get Revamp


New formulations of two air and waterproof barriers mean easier application, according to the products’ manufacturer.

R-Guard Cat 5 and R-Guard Cat 5 Rain Screen, liquid-applied barriers from Prosoco Inc., have both been reformulated, the company says, so that they’re easier to roll on than in the past. Prosoco notes that this will be especially noticeable in low-temperature application situations.

About the Products

R-Guard Cat 5 is described as a one-component air and waterproof barrier that creates a seamless elastomeric weatherproofing membrane. R-Guard Cat 5 Rain Screen is an air and water-resistive barrier, for use in the construction of rain screens.

Both products are solvent-free, isocyanate-free and phthalate-free, and are touted as capable of standing up to the heavy rains and 155 mph winds of a Category 5 hurricane.

Faster Cure Time

Prosoco notes that in addition to improved rheology, the new formulation offers a quicker cure time than in the past.

According to Prosoco, both products cure in wet conditions and on damp substrates.

The products can be used in conjunction with previous formulations.
