Penofin Oil Stain Review

Penofin Blue has a small odor. This product is easy to apply and absorbs well into the wood. The initial appearance looks pretty good, but not great. The instructions stress wiping the stain after applying to reduce sticky finish. Even though the finish looks OK, who really wants to wipe their entire deck after staining? 14 month weathering results were the worst of anything we tested.  Severe failure, graying, color loss and mildew growth were all terrible.

    I applied the blue Penofin stain to my new deck last summer. This spring now the appearance is horrible. All kinds of gray coming through and Discoloration. It is so disconcerting because I worked so hard at it. Also, at $50 a gallon I didn’t receive the quality I thought I was. The original appearance was fantastic but did not last at all. The product will cause spontaneous combustion also. In the hot sun the sponge I was using actually started burning which was quite weird. Very volatile.
