QUV Testing Results

The different deck materials were tested in the ACCELERATED WEATHERING CHAMBER to determine the amount of discoloration of the wood when exposed to continuous cycles of light, dark and high humidity.  Our formulation of shades has been made with the finest transparent oxide pigments to give the stains their true colors while maintaining their resistance to light discoloration. We have added to this formula the same UV inhibitors found in premium automotive paints.


​SUMMARY: All tests were done in clear and shaded varieties on Douglas Fir, Redwood and Cedar

Coating failure determined by water absorption and color shift from coated un-exposed wood samples.   QUV is a comparative test and does not replicate specific hours of exterior exposure. Test concluded at 1000hrs exposure
