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.

- Applications
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 fullscale 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. WC-5 should not be applied where it will be subjected to continual standing water.
