- Applications
WC-7 is suitable for application by brush, trowel, or spray (application method should be specified when ordering). Its normal recommended dry thickness for full-scale outdoor protection is 1/16” (63mils), but it also provides excellent protection at thinner thicknesses. A minimum dry film thickness of 40 mils is recommended. When dry, it provides a tough, durable, flexible film which affords excellent protection from the elements, other sources of water, and mechanical abuse at a wide range of temperatures. WC-7should not be applied where it will be subjected to standing water or where the requirement is for a vapor barrier.
