Penofin Blue Label Wood Deck Stain Review 3.6/5 (7)

Penofin Blue Label Stain Review

Penofin Blue Label Stain Review

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 Scores (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 it’s 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. Very small amount of wearing was only visible on the horizontal parts (cross beams) of the fence.

Cost Per Square Foot: 8

– Penofin Blue Label costs about $35 a gallon. Less expensive then the Penofin Red Label but the Blue Label (550 version) does require 2 coats of stain. We used 5 gallons of the Blue Label for our 600 feet (square) of fencing for the two coats.

Preventing Mold/Mildew/Algae: 8

– The Penofin Blue Label does a decent job with mold prevention. The only noticeable mold was at the bottom of the fence where the wood faces north. In this area there was mold and green algae growing.

Ease of Application: 8

– The Penofin Blue Label is “thin” and applies easily with our pump up sprayer. We tarped all the grass along the bottom of the fence and sprayed the stain up and down. Very little need to back wipe as the Blue Label absorbed into the wood quickly. First coat absorbed to the point where the stain color was very light. The second coat of stain really gave the enhanced look we wanted and evened out the appearance. Second coat applied twice as far as the first coat.

Color Shifting (darkening) after 2 Years: 6

– Penofin Blue Label did darken in the sunny areas. This seems to be normal for Penofin as the stain itself darkens. The Blue Label does better then the Red Label Penofin version though. We suspect that higher usage of trans-oxides means the probability of the stain darkening in color increases.

Difficulty of Reapplication: 7

– A quality wood deck cleaner should be able to revive the wood color. A stain stripper should be used if the Penofin has darkened considerably. For our test fence we felt a good cleaning would be enough for reapplication without the need for stripping.

Overall Score Penofin Blue Label Wood Deck Stain at 2 Year Period: 7.75

– Penofin Blue Label is a decent wood stain. We really like the colors that Penofin makes and the way the stain absorbs into the wood. In general the better a stain absorbs, the better it works. What we do not like about the Penofin Blue Label was the average UV resistance and the darkening that can happen after 2 years of sun exposure. Penofin Wood Stains have a strong odor as well that can take 2-3 days to dissipate.

    So far I've used about 20 gallons of the blue label cedar tint on our house and a couple of larger boat interiors.
    Here's my experience re fir floors. I thought penofin was a sealer so I rubbed in two coats. A year later I put my ski machine on the floor with sweat flying all over the place. No biggy I thought. It's sealed!
    When later I went to clean it up, the spots wouldn't come up. They'd permanently marked the floor. I sanded with 80 grit & finished with 120 on a palm sander. They seemed to disappear. Then I Re oiled and varnished. A lot of the spots magically returned.
    Is penofin a sealer? Not against sweat. The perspiration etched into the wood like it was sitting beneath the oil.

    That's been my experience. Maybe they should add a 'sweat' disclaimer to the can. Had I know, I would have varnished the floors instead, also easier to clean up.

    I have a 2 week old, cedar fence, rough sawn. Live in the Pacific Northwest, so..lots of rain in the winter/fall/spring but lots of sun in the summer. Went to my local lumber store and they suggested Penofin Red Label. Per the review on this website, it sounds like Red Label has more of a reputation of darkening over the years compared to Blue Label. My questions are:
    1) is Penofin a good stain/sealer for the PNW?
    2) should I use Blue label or Red label?
    3) is it too early to stain my fence? or should I wait?

    • Summer, you can use Penofin for any wood but is does seem to darken quite a bit from mold and such. I would use Blue over the Red. Rough wood can be stained right away.

  3. Pam says:

    I did not wipe after applying. What do I need to do to get the tackiness off?

  4. Fred says:

    Tempted to use Penofin blue on some outdoor cedar furniture. Applied some to a sample piece, and typical softwood blotching was evident. Any thoughts? Maybe thin out some clear and use it as an exterior wood conditioner? I may or may not varnish over it, leaning to not.

    • Never varnish outside wood. It will peel. We do not use much Penofin die to the issues they have with darkening.

      • Fred says:

        Even with a marine spar varnish / urethane?

        Do you have a preferred way to color outdoor cedar that is easy to maintain and doesn’t blotch out? (include product names?). Preferably one that’s available in quarts ..

        I can’t believe how hard it’s become to put a competent coating on outdoor things.

    I have cedar siding (and a couple log supports). 4 years owned and did nothing. Color is dark in the shade, grey in the sun. I like a dark brown with red, so I'm thinking the blue label (I'm in Calif) would be best for me because i like darkening instead of lightening over time. Place is huge so can only do one side at a time. Cannot sand (thin cedar). Can lightly wire brush – what is my best prep? The incense cedar logs were peeled 2 years ago and have mold, so I'd use up the Cabot problem solver I have on hand, unless advised not to.

    Separate question – what prep uses the least amount of water? – water restrictions here. Wish I could just use our air compressor.

    • You cannot prep with cleaner/brighteners without using a lot of water. Do not wire brush or use anything metal. Light sanding you really be the only thing you can do.

  7. Pete says:

    I have a part of my cedar fence that needs to be stained and I'm out of the lighter colored red label Penofins but have some darker colored Penofins left over from another job. Can I mix some clear Cabots deck stain wtih this to lighten it up a bit for an obscure part of the yard?

  8. Jean says:

    I live in Maine by a lake under pines, there is not much sun. I am siding my house with white cedar. This Blue Penefin looks like the best choice. How does it last in a cold climate? Do I need to be concerned about mildew given the lack of sun?
