The many colors of this non-glossy, satin finish coating provide an attractive finish on numerous types of applications.

Recommended To Use With #1107 Epoxy Primer

This aliphatic moisture cure urethane is excellent for both exterior and interior use. The hassle of mixing is eliminated when you use DuraThane XL; this one-component product makes application a breeze. Offering high chemical resistance and strong resistance to abrasion, DuraThane XL is a coating that goes the distance. And, offering improved cleanability, this urethane coating has taken yet another step toward ultimate convenience. DuraThane XL also provides a significant degree of flexibility.

In order to ensure the best possible adhesion to the floor, we highly recommend that you use Superior Industries’ #1107 Epoxy Primer before applying DuraThane XL. #1107 Epoxy Primer is a two component, low viscosity epoxy primer that forms a tough but flexible film. This high solids primer offers excellent penetration and superior adhesion. It is moisture tolerant and stress relieving, featuring very low VOC’s, low tensile modulus, and high tensile elongation. #1107 Epoxy Primer is very resilient and will bring about strong adhesion when used in concert with DuraThane XL. #1107 Epoxy Primer is available in both 3 gallon kits and 15 gallon kits.
