Behr "Deck Over"- First use and Review

I've always been skeptical of "miracle" products but I had a chance to use this one and I was almost speechless when I was done. Wood check gaps and splits up to about 3/16" were filled in (even on vertical surfaces!) as if they'd been caulked. When I was done the old deck looked almost new :cool:

I tried a roller but this ain't paint, it's more like heavy slick mud and the roller slid without depositing anything so in the end I brushed the whole deck instead. For the wider cracks I brushed cross-grain to fill them, then laid a dry smoothing stroke along the grain to finish. It dries fast in the heat and sun but I was able to keep up with it. It's heavy on the brush, about double what a normal brush full of paint weighs and gloppy but it spreads well though again that's about twice what painting takes. 5 gallons is supposed to cover 375 SqFt with 2 coats but I did about the same in one. Cutting in close is a royal pain because of the thickness of the mix but a slight amount of water mixed in helped considerably.

I did another deck with this stuff yesterday with it in cheap-rental-marginal condition, and once again the results looked amazing. It's a textured finish meant for floors but it works great on rails and pickets too. The texture looks like fine sand but isn't really abrasive to the touch. I don't know how durable it is yet- that remains to be seen- and of course it's not intended to fix any structural issues with the wood but if I were going to 'flip' a house with a weathered old deck I'd use this in preference to replacing the weathered but sound wood.

If anybody here has any tips on applying this stuff I'm all ears- that customer has a lot of old decks and he's as impressed with the results as I am so there will be more in my future. I'd like to roll it rather than brush it even if I have to lay it off with my brush after rolling. Even with all my brushing experience this stuff is a real chore to use but it performs miracles. I never thought I'd say that but it's true!

BIL installed it on his deck last year. I saw it this past summer and it has held up so far not that a year is a real test. His experience sounds like yours. He painted everything, deck, railings and pickets. His deck is PT yellow pine about 20 years old never stained as far as I know. A big deck,I think he said he spent over $1000.

I wonder if a fine toothed trowel will help spread it around?

I have used this product. It is definitely easier to use if you can stay out of the sun. The cool and higher humidity of the early morning also works to your advantage. I would not use DeckOver on the balusters and trim. Behr makes matching color solid hide stains which go further and brush far easier. I would also consider doing all the gaps between the decking lumber first with the solid hide stain. This allows the application of DeckOver much easier as you only have to deal with coating the actual top surface. Application is with a good quality 1/2 inch roller cover. Granted, it is more like "steam rolling" than traditional paint rolling. You want to do just a couple boards at a time and do the full length of the boards. This allows you to keep a "wet edge"and improve the final appearance of the product.

My DeckOver has gone through two winters now. If you get through one wet winter, you should be able to enjoy several years before re-coating is necessary. If a decking product is going to fail, if will usually do it after the first winter.

Houston, you're killing me! Thanks for the laugh this morning ;)

I tried a 1/2" nap roller but it just slid no matter the various pressure I tried. I'm thinking a loose-knit sleeve for block filler might work but it might just slide along worse. And board edges were a bugger with this thick stuff. Next round I'm going to take the time to try all my other roller sleeve options. The second deck did show me that it likes specific brushes, so far a Purdy XL medium stiff is the clear winner going 50% farther per brush-full with less spreading needed. Some brushes were much like my roller; the product didn't want to leave it and go onto the surface.

My big landlord customer bought this stuff cheap- he's got an 'arrangement' for getting mis-tinted paints at unbelievable prices; he'd die before spending the retail price on this. Thinning helped immensely but reduced the color coverage so it was only a partial solution as I get one shot at these, no time or money for a second coat, just a touch-up when I'm finished.

Good to know it seems to last, that is the biggest problem we have with deck/porch paints. Wouldn't be a problem for most folks but a lot of what I deal with is stuff in marginal condition where we're trying to get as many years from it as we can and with this filling the weather-checks it should keep more water out of the wood gaining that. Now if I can only find an easier application method- this much heavy brushwork doesn't set well with me at my age!

Update on my OP:

It seems the first bucket of this stuff might have been old, frozen, or otherwise mistreated. It also seems the workability is related to the tinting. I've used 4 colors so far and they all handle differently but some roll out OK. What I'm finding now is that when applied by roller, you lose a lit of the crack-filling ability even when tolled dripping wet. Brushing it in across the grain fills the cracks best, then you smooth it with the grain for best appearance. Nothing I tried with the roller gave me results much better than a good paint does. I tried 3/8" to 3/4" naps and from lightly loaded to dripping wet. I also tried full-strength to a few percent of water added. Nothing seemed to fill the wider cracks more than a normal paint would.

So in conclusion, this product does what it says when brushed, but is not worth the extra expense when rolled.

Phil,

The videos show it brushed on first to fill the holes then rollered to even out the top coat. That worked well on my deck.

Re: Behr "Deck Over"- First use and Review

I didn't watch the vids Paul, but I see no point in 'backrolling' when brushing correctly will achieve the same results and you're already there with your brush. Do remember that I'm also doing this in one coat, not the recommended two, which I think is more realistic for what many people will do with this or any other paint product.

Folks will always try to avoid extra work when the first round seems to do the job well enough- I know that I do as long as I'm certain the results of that approach are going to be acceptable. I'll always do whatever is necessary and I'm always the hardest worker on a job, but actually I'm inherently a lazy sort who works so hard only because that lets me finish sooner so I can be lazy again sooner :p
