Usage SummaryBlank space if empty.
PreparationBlank space if empty.

The following steps are recommended for best results.

  • Use a product such as BEHR PREMIUM® NO. 64 Wood Stain & Finish Stripper to remove loose wood fibers, latex, oil-based and 100% acrylic coatings on new or weathered wood.
  • BEHR PREMIUM® NO. 63 All-In-One Wood Cleaner MUST be used following NO. 64 to clean, brighten & neutralize wood.
  • When NO. 64 is not needed, use a product such as NO. 63 to clean and brighten the wood surface and to remove light to medium exterior stains caused by mold, mildew, algae & fungus.
  • On new wood, use a product such as NO. 63 to remove mill glaze and open the pores of the wood. Rinse thoroughly and allow to dry before coating. Lightly sand to remove remaining wood fibers/fuzz.
ApplicationBlank space if empty.

For best results, a pad applicator is recommended over large areas.

  • Must apply between 40-90˚F (4.5-32˚C). Do not use if rain is expected within 24 hours. The wood surface must be completely dry before application.
  • Intermix multiple containers to ensure color uniformity. DO NOT THIN PRODUCT.
  • Stir product occasionally throughout application. Test product for penetration and color on a small hidden area before proceeding.
  • Use a nylon/polyester brush for areas requiring more accuracy. Use of rollers should be limited to rough surfaces only.
  • Use 3/8” nap or longer when appropriate. A high quality pump sprayer with a variable tip or an airless sprayer with a .015 - .019" tip may be used.
  • Work in small sections lightly saturating the surface and immediately back-brush or use pad applicator to eliminate puddling, remove excess and evenly distribute the finish.
  • Maintain a wet edge when applying. Apply product end-to-end or to board lengths to prevent lap marks.
  • Over application of finish will lead to surface failure including peeling and cracking. Avoid applying finish too heavily. For optimum performance, coat all six sides of wood.

Rated 4 out of 5 by from nice wood finish! This finish is wonderful, great coverage and worth every penny!

Rated 5 out of 5 by from EXCELLENT and SUPERIOR Stain for exterior stain This is the best stain I have used to date. Goes on thick and penetrates every Crack and crevice.Awesome product. One coat and done. Fence came out perfect. The stain is pretty good stuff. Take your time, prepare your surface, follow the instructions. Sometimes the "best" isn't always the best! I recommend this over the premium product.

Rated 5 out of 5 by from The beast I ever used ! Bought this on the reco of the Home assistant. Went on easily, covered beautifully and dried like satin. Looks beautiful and the uniform of color has gotten us nothing but compliments. Rain beads up and dirt washes away.

Rated 5 out of 5 by from I love this stuff! I am a (frustrated) amateur when it comes to staining wood. I have tried a half dozen different stains, and was not especially satisfied with any of them (not Behr products). However, THIS one is the only one to totally satisfy me with regards to ease of use, ease of clean-up, and beauty of finished product. I have used the cedar naturaltone and the redwood. I used the stains to treat plain pine wood for raised garden beds and it worked perfectly. The beds look like more expensive wood at a fraction of the cost. They are protected from water, sun damage, and mildew (OK, confession: mildew is not much of a problem here in Arizona!) I highly recommend this product, though I can't comment on its durability yet as I've only used it for the last 2 months.

Rated 5 out of 5 by from Would recommend I have used Behr products in the past, Behr never fails me, good coverage goes on smooth out last other brands

Rated 4 out of 5 by from Great coverage and color We used this to stain our cedar fence and LOVE the color. We used the clear tone two years ago, and it is doing a great job. Took off 1 star because although we followed directions and thoroughly coated everything, there are a couple maintenance spots. But overall very happy with it and will purchase again!

Rated 1 out of 5 by from VERY Misleading I wanted clear. It wasn't clear. It dried as CARAMEL. The can says CLEAR. My deck project is not what I'd hoped. I am so adaptable but this, so very disappointing.
Date published: 2020-06-11
Rated 4 out of 5 by from Natural look I have a porch, screen porch, and deck, all stained with Behr Transparent waterproofing wood finish. It is easy to apply. Looks great after 2 years on the low traffic area. The high traffic area is fading after 2 years.
Date published: 2020-06-02
Rated 5 out of 5 by from Very good protection at a very good price Just finished protecting my expensive outdoor teak furniture (table for 12 and with chairs, and a bar with chairs as well) with this product and got a reliably good result. I have used this product (in a pre-tinted mild cedar color) before for the same purpose, and its nice when you only have to use it once every 3 years - easy to use and easy to clean up.
Date published: 2020-06-01
Rated 4 out of 5 by from Looks beautiful I enjoy the look, just wish it would last longer. The sun seems to really torture my deck.
Date published: 2020-05-31
Rated 3 out of 5 by from Great at first I followed all the rules. Pressure washed the deck 3x sanded twice with actual pro level machines and applied exactly as recommended. Now about 16 months later it’s chipping and wearing quickly in a low traffic area deck. I was hoping for more longevity.

Rated 5 out of 5 by from Never Peels! I'm a very busy handyman doing decks alomost exlusivly, these Behr deck exterior stains are the products I always talk my customers into using for ease of maintenace and application. I have never had a peeling problem with any of my customers decks or porches. These products "to me" are the leading deck products to reach for when staining exteroir wood. My personal property I have four buildings with cedar sidng, pine siding and wood decks, all have Behr exterior stains, I built this place in 1984 and this place still looks awesome....

Rated 5 out of 5 by from 'Behr' - strongest in the woods! I purchased Behr Transparent Waterproofing to cover a 28 year old deck. The comments from everyone who has seen the 'weathered' 28 year deck was, "WOW, when did you get a new deck" Obviously, I was transparent and told them I had a Behr help me finish it.
