Coverage rates for R-Guard products will vary depending on surface porosity, moisture uptake, and other factors. OSB, CMU and some gypsum sheathing products are highly absorbent and require additional material to achieve hide and the necessary mil thickness for a pinhole-free barrier. In those cases, more than two coats may be required. Actual application rates must be determined through field mock-up applications.

We are always here to help by phone or in the field. Call us for additional support or to locate an authorized R-Guard distributor.
