The “Risky” Waterborne Roof Coating “Shoulder Season”

By William A. Kirn, RRC Technical Director National Coatings Corporation

It doesn’t require looking at the calendar or the trees changing colors to realize that as roofing contractors, we are entering the “shoulder season”. Fall months (and Spring) bring unique challenges for applying waterborne roof coatings. Early morning fog and overnight dew can wash away or serious damage an otherwise excellent roof coating application. Waiting for the weather to improve delays the project completion (and getting paid). Applying coating only in late morning and early afternoon, is still labor intensive and costly. Applying additional thinner coats is also costly. Solvent borne coatings are less vulnerable, but are more costly and carry fire and odor hazards and concerns. However there is a family of waterborne roof coating products that can solve these problems:

National Coatings Corporation has developed a family of waterborne roof coatings that “set” quickly after application and resist the damaging effects of dew, light rain and fog. Even though the relative humidly is high and the coatings are wet, they develop a “structure”, preventing wash off. This is caused by a novel “quickset” chemical reaction incorporated into the coatings.

THESE PRODUCTS ARE:

AcryShield A600 Premium elastomeric roof coating. Fast-setting version of A500, for resisting early wash-off associated with heavy dew and light rain.

AcryShield A610 Premium elastomeric roof coating. Fast-setting version of A510, for resisting early wash-off associated with heavy dew and light rain.

AcryShield A640 Elastomeric roof coating. Fast-setting version of A400, for resisting early wash-off associated with heavy dew and light rain.
