UV Resistance of Water Based Finish

Question

Are water-based finishes such as water-based polyurethane as UV resistant as the corresponding oil-based finishes?—Bob Jarratt

Answer

Jim Morris replies: The difference between water-based resins and solvent-based resins are very minute as far as UV protection go. The manufactures put UV blockers in the finishes to give them more protection from the sun, so in general they’re both the same. You have to read the labels of the finish to find which ones have the UV blockers in them.
