Penofin Blue Label Review 2026
Penofin Blue Label Stain Review
Penofin Blue Lable continues to have issues with darkening or turning black on a vast majority of wood decks and exterior wood.
Penofin (PENetrating Oil FINish) Blue Label preserves and protects exterior wood. Using trans-oxide pigments, Penofin Blue label retains the wood’s natural colors while penetrating deep into the wood fibers. Use Penofin Blue Label on fences, decks, and unfinished exterior wood siding.
Note: For this test, we used the Penofin Blue label on a vertical fence in Texas.
Penofin Blue Label Wood Deck Stain Rating (1-10)
Appearance After Initial Stain Application: 9
– Penofin stains always present some of the most natural-looking wood. The Cedar color used highlighted the grain without adding too much orange or yellow tones. Penetration into the fence was excellent.
Preventing UV Graying at 2 Year Mark: 7
– After 22 months we evaluated the Penofin Blue Label on the fence. Color retention was decent as the Blue Label had only lost about 30% of its original Cedar color.
Wear/Tear and Peeling: 9
– Excellent penetration into the wood means very little peeling. The Penofin Blue Label deserves a high score for this. A very small amount of wearing was only visible on the horizontal parts (cross beams) of the fence.
