WC-5 is a heavy bodied, water based, vinyl acrylic mastic, for use over all types of insulation systems, both indoors and outdoors. It can also be applied as a protective coating over masonry surfaces and a variety of other substrates. WC-5 is suitable for application by brush, trowel, or spray (application method should be specified when ordering). After drying it becomes a tough, flexible, color retentive coating which is resistant to weather, alkalis, oil, grease, moisture and mechanical damage. Its normal recommended dry thickness for full scale outdoor protection is 1/16 in but it also provides excellent protection at thinner thicknesses. A minimum dry film thickness of 40 mil is recommended. WC-5 should not be applied where it will be subjected to continual standing water. WC-5 must be protected from freezing during storage. It must be protected during and after application, from precipitation, freezing, oil, grease and foot traffic until thoroughly cured. WC-5 is breathing type mastic which allows water vapor to pass through it. This is a benefit because residual water trapped underneath the coating is allowed to escape in the form of water vapor. WC-5 should not be used over a low temperature system unless a vapor barrier is present. WC-5 is USDA acceptable for use in meat, poultry and food processing plants.
