Application Method
Applications

Thick-Kote™ is formulated for easy application by brush or trowel, but can also be sprayed if needed. Its recommended dry thickness ranges from 40 mils to 63 mils depending on the degree of protection required, and when properly applied within this thickness range, it provides excellent protection from the elements, other sources of water, and physical damage over a wide range of temperatures. These dry film thicknesses are achieved at a wet application of four to six gallons per 100 sq. ft. Thick-Kote™ should not be applied where it will be subjected to continual standing water or where the requirement is for a vapor barrier.
