Just did my front porch deck, rear deck, and swimming poll deck in Olympic Elite, bought at Lowes. So far it looks good,been about 6 weeks now, will know better next summer. I have used a lot of different treatments over the last 20 years, never found anything that lasted beyond 3 years. I would stay away from Thompson water seal, doesn't seem to last more than a year, but that's just my opinion. A must is a good clean surface before applying.
I've been doing a lot of research in preparation for doing my deck. (If I research long enough, maybe I'll put it off until next year. LOL.) Here's what I've found.... Stay away from Behr products. User reviews are terrible. The best ratings I've found are for a brand called "Defy". Seems to the best rated of anything out there. Unfortunately you have to order it via internet. That having been said, I've not used it yet, so I don't have first hand experience. We've use Sherwin Williams Deckscapes twice and I'm not impressed so far.
Did two sets of deck railings with Behr last summer. Applied great not a blemish to be found so far.
Also, used Behr DeckOver on decking last summer. He had Olympic on prior that was beginning to fail after about 5 years. Wood was also beginning to check. DeckOver worked great and not a blemish. Only complaint is that I picked a dark color and the dog's dusty footprints show easily.
Read good things about Silkens but is expensive. BTW: Behr isn't cheap but I am very pleased.
I wouldnt waste your money on that bear deck over paint, my dad used it and my friends dad on both of their decks and they starting to chip and flake off, and does not seal cracks like the commerical shows unless your putting sevral coats on. I wasnt even remotely happy with the 2 in 1 paint and primer when i used it in my house. As for the deck depending on the wood if its new or in good condtion id go with semi but i like the look of the grain of the wood.
My deck and dock at the shore take a beating and stains and Thompson's water seal were not cutting it anymore. I used Rustolium deck restore and was very happy with how it turned out.
I think issues those have with this and the Buhr were due to not prepping as recommended. We power washed, sanded and used filler in wide cracks but the rolling part was a piece of cake.
you do need to coat twice but the result was a lot better than I thought they would be. It didn't turn out looking like LumbeRock or Trex but it dose look good.
There is about 50 colors they offer.
No matter what you use if your going to pop open the can and start rolling its going to fail.
Many times stain failures are do to poor prep. Failure to let pressure treated dry will create bubbles and cracks. If any moisture is present before applying or shortly after application will result in failure.
If the checks/cracks are too big no deck restore will work. On my deck at home, the pressure treated 2x6 were never treated and after 20+ years, no restoration was going to work. I had to strip all the decking and I put down composite. The decking I put DeckOver on was protected, although it was beginning to show a lot of wear. It had small checks and two coats of DeckOver did a great job with no signs of deterioration. It appears to be a very substantial coating.
It was interesting to see how the galvanized nails/fasteners had corroded over the years. Some had all but disappeared.
I also looked online and found Defy products had good ratings. I bought a 5 gallon bucket and it lasted well for 4 years. I need to seal again this summer and plan on using it. I found a place on the internet that ships free and plan on getting it there.
Deck stains can protect a wooden deck and concrete deck pretty good for over 20 years, but they don't seem to protect themselves very well. Been painting wooden decks and concrete decks for years. Repeat and repeat.
I use CWF with a cedar tint to coat my house siding, which is Tongue & Groove cedar. For my wooden deck, I use Olympic Maximum Stain, which is a cover stain, not transparent. It's pricey at over $30 per gallon, but a good stain. I also like that it is a latex base. I do this every 3 or so years ?
I use TWP 1500 series on my deck and house. Made by Ametco can I bought online. It came out of Georgia. It has been on the house (board and batten hemlock) for 2 years and is still beading water. I ended up putting 33 gallons on the deck this year. (Wood aged for 2 years before treating it)
Most deck stains fail within 4 years. They are designed to do so. The key to a properly formulated stain is it to erode and not flake. The wood benieth deterieates and when the stain lasts longer than the wood it flakes. Idealy the wood and stain erodes at the same rate. BHER deck stains are good. If I were choosing I would look for a stain with the highest VOC levels. They will be your best.
