THE WECKMAN ANTI-CONDENSATION COATING OFFERS AN ALTERNATIVE TO ROOF COVER SHEETING – IT IS OVER 30% MORE ABSORBENT

WECKMAN anti-condensation coating provides effective protection against moisture developing on the underside of roofing sheets. Separate roof cover sheeting may not be required. Compared to anti-condensation sprays, our coating offers excellent absorption properties: up to 900 g/m2 on a horizontal surface (water).
The coating is available for models W-20R, W-45ER and W-45JR.
