See Here for First Review: Penofin Exotic Hardwood Stain Review
Only Penofin’s Hardwood wood stain can penetrate dense hardwoods that need nourishing and stabilizing. This unique formula penetrates deep into the wood fibers and does not create a surface film. Unlike high-solid wood stains that simply coat the surface, Penofin’s Hardwood Finish, using sustainably harvested Brazilian Rosewood Oil, is the choice of wood experts who know that wood penetration is key to longevity and beauty. Penofin allows the wood to breathe, important in working with exotic hardwoods such as mahogany, teak, Ipe, Brazillian Redwood, and many other species. Only Penofin Penetrating Oil Finish can meet the needs of hardwood in fiber protection, penetration, stabilizing, and nourishing.
Important Note: Testing for Exotic Hardwood Deck Stains
Exotic hardwoods such as IPE are extremely dense and difficult to penetrate. These wood types, when stained will always fade faster the other woods such as Cedar, Redwood, and Pine. Testing will be changed to 1 year instead of 2 years for exotic hardwoods.
Penofin Hardwood Wood Stain Scores (1-10)
Appearance After Initial Stain Application: 10
In our opinion, Penofin stains give one of the best-finished appearances to wood once dry. The IPE was highlighted beautifully with natural reddish-brown colors.
Preventing UV Graying at 1 Year Mark: 2
The Penofin retained little to no color after a year on the Ipe. The customer called us after 6 months and said the stain had disappeared in the sun and turned black in shaded parts? We inspected and agreed with the homeowner. Penofin explained to us that IPE needs to be reapplied every 3-6 months if you want to retain color.
Wear/Tear and Peeling: 8
Penofin has always had great penetration abilities, even on exotic hardwoods. There was very little wearing.
Cost Per Square Foot: 7
One gallon was used for the 300 sq. feet. Each gallon costs about $48. Great coverage but on the costlier side.
Preventing Mold/Mildew/Algae: 4
The Penofin had darkened considerably. A good amount of this was due to mold growing. Little black dots were very noticeable in the wood grain.
Ease of Application: 7
The reason we gave the Penofin a 7 here is not due to the application but rather the smell. Penofin applied easily but the odor is horrible. Makes your eyes water! If not for the smell, we would have given this a 9 or 10.
Color Shifting (darkening) after 2 Years: 2
Penofin has an issue with turning brown or even black in color after exposure to the elements. We have seen this on numerous decks stained with Penofin through the years. On this IPE Deck, the color had faded significantly in the sunny areas and turned dark brown in the covered areas.
Difficulty of Reapplication: 8
Should not be hard to remove the darkened Penofin with a stain stripper and a light pressure washing.
Overall Score Penofin Hardwood Stain at 1 Year Period: 6
It is really too bad that Penofin has an obvious issue with darkening as it is a beautiful product when first applied. Research online shows numerous complaints on this subject. If it could somehow fix this issue, it would score much better.
The results with the second review were worse than the first. Could be changed in UV exposure and wood type.
