Update 2019 on Penofin Red Label
Penofin continues to have issues with darkening or turning black on a vast majority of wood decks and exterior wood.
Penofin (PENetrating Oil FINish) Ultra Red Label wood and deck stain contains a Brazillian Rosewood Oil that allows the stain to penetrate deeply into the wood. Formulated for maximum protection for all types of exterior wood. Penofin Ultra Premium Red Label is perfect where rain, wind, snow or high elevations are encountered. Trans-oxide pigments offer 99% Ultra Violet Radiation protection
Penofin Ultra Red Label Wood Stain Scores (1-10)
Appearance After Initial Stain Application: 9
– Penofin Ultra in the Western Red Cedar color has a beautiful appearance when dried. One of the best stains we have tested when it comes to penetration into the wood and highlighting the natural wood tones.
Preventing UV Graying at 2 Year Mark: 7
– At the 2 year mark, the Penofin Ultra Premium stain did an adequate job of preventing UV graying. The high solids of the trans-oxide pigments absorbed the UV radiation, preventing the graying of the wood. About 70% of the color remained since initial application.
Wear/Tear and Peeling: 8
– The Penofin Ultra had little to no peeling on the surface, We expected these results since the stain absorbed so well into the cedar wood. There was some wearing on about 5-10% of the decking surface mostly in the traffic areas.
Cost Per Square Foot: 7
– Penofin Ultra costs about $45 a gallon. This is on the high side of quality deck stains. The square footage was not what the manufacturer claimed of 200-300 feet. Square footage was closer to 150 sq. feet per gallon. We used 6 gallons for the 800-foot deck and trellis.
Preventing Mold/Mildew/Algae: 6
– The Penofin Ultra seemed to attract a decent amount of mold spores even though the deck was in full sun. The mold was only visible on the horizontal decking surface. On inspection. the mold was growing in the stain and could not be cleaned off with a wet towel.
Ease of Application: 8
– The Penofin Red Label applied very easily to the surface. We watched the stain absorb into the wood within a few minutes of application. We used a stain sprayer to apply then back wiped with an exterior stain pad. The final result was an even beautiful finish. One issue was the smell. Penofin has one of the worst odors of all deck stains tested.
Color Shifting (darkening) after 2 Years: 5
– Penofin scored the lowest in color shifting as the finished achieved a “brownish” color after the 2-year mark. This issue was only on the flooring while the vertical wood railings and trellis did not darken. A good deck cleaner should be able to revive the color when it is time to reapply.
Difficulty of Reapplication: 7
– Since Penofin had “darkened” in color we would suggest that the stain is removed with a stain stripper followed by a wood brightener. This would not be a difficult strip, though. Since Penofin penetrates so well, it will come off rather easily with a standard deck stripper.
Overall Score Penofin Ultra Premium at 2 Year Period: 7.14
– Penofin Ultra scores high in a few areas and most importantly has one of the best-finished looks of all stain tested. We were disappointed in the color shifting after two years and the smell during application. We would expect a high-quality stain to not darken in color. Our result though may not be the norm as Penofin products clearly have devoted customers who continue to use their products.
