New thought on plywood deck coating

[bonz_d]

As I'm game to sometimes try something new I came across this and was wondering what anyone here thinks Has anyone tried this stuff on anything?

Anyways I'm thinking of trying it on the plywood decking I'll be replacing over the winter in my Alumacraft and depending on how it looks not putting any other coverings over the top. Like carpet or vinyl

Ayuh,... It appears to me, to be the next step in the formulation of pick-up bedliner coatin's,...

I've seen samples of it at Lowes. I've considered redoing my utility trailer floor with it as a test. I've seen it applied on a couple of decks, and it seems pretty nice. Not slick when wet, and has a nice finish.

I wouldn't coat bare plywood w/ it. As an alternative to using nautolex, maybe, over the sealed plywood.

In a boat, over plywood, the product isn't going to perform exactly the same as it does on dimensioned lumber on a deck, IMO.

Jasoutside used DeckOver (HomeDepot & Behr's version of the same type of product) on his now topless Islander project. I don't recall it going on the Jet he sold or the SeaNymph he still has (maybe still has ??). He put multiple coats of epoxy on the plywood 1st as a sealer and then applied the DeckOver.

It hasn't seen water use yet, may not in 2015 either, so no 'in use' input about longevity. But he's been working on and around the DeckOver on his boat's deck for over 18months, IIRC. I don't recall any complaints.

If I wanted to go through the expense and trouble of sealing the ply with epoxy then I would just as much spend the money on treated marine plywood that was originally used...... About the same cost with a whole lot less work, mess and much safer to use.

Why would you say it will not perform the same on ply as lumber? From what I've read either would have to be clean, dry, and be able to absorb water before it's applied.

Bedliner wasn't engineered to be absorbed it was intended to be applied directly to metal.

The decks I've seen it on were regular lumber both pressure treated and natural wood. I may be wrong, but I thought this product sealed the wood making it water proof, and was UV resistant.

That would be my impression.

It isnt the top side surface water resistance that concerns me.

Like you, i've never put it on sealed or unsealed plywood or put it in a boat.

I have used the DeckOver on a project that was NOT its intended purpose. Against my recommendation, what was coated wasnt sealed, although i suspect the rest of the prep work wasnt done to what I specified either.

Surface water wasnt the problem that lead to failure. It was moisture from below that basically pushed (lifted) the coating off. It started w/in days of final application.

If the prep work had been done right, AND a sealer had been used, i believe the chance of success would have been much higher or i wouldnt have made the recommendation to use it when i was asked.

I have lots of experience building & rebuilding decks. Even those that are inches off the ground have air flow in & around them. So if by some chance the backside gets wet, it can air dry. The product is intended to allow for expansion and contraction but isnt particularly aggressive in how firmly its stuck, IMO.

In a boat, i am fairly confident that at some point unsealed plywood (esp edges) will come in contact w water. And even if you store yours bow up and drain plug out, it wont be dry as quick or as well as a deck would, and it wont be evident that the coating is letting go immediately and when it does it'll be in a finished boat. And if wet, when its subjected to heat and humidity any minor flaw can become a much larger problem because the air under a bubble will expand. Again in a finished boat.

i dont recommend marine ply for boat builds because its expensive and i can recommend good alternatives that cost less. Some protect more then others, but what i recommend is only slightly more expensive then other less sealing methods.

i dont understand why the $100+/- to seal ply or $200 to foam a boat arent worth it.

Thanks for in input!

For one I have found a distributor that I can get treated marine ply for only $16.00 a sheet more than Premium ACX ply. Which would be the same ply Alumacraft used when they built this boat 26 years ago. I also think it would have lasted much longer if it had been properly cared for. Where does the foam thing come from?

From what I've read on this Restore product is that the wood has to be completely dry then treated with a primer otherwise it will blister and peel. Prep work is very well stated from Rustoleum. From what I read it will not adhear to a nonpourous surface. So applying over sealed wood. like epoxy, would not work. In their FAQ there are many asking about what you describe and from Rustoleum it all goes back to prep work or the wood being wet before application.

I do not disagree on the point of water intrusion, it still happens with epoxy encapsulated wood. But I do not want to turn this into another argument of epoxy vs anything else. Already been down that road. So please let's stick to the question at hand.

The plywood that was original from Alumacraft was 1/2'. Not 5/8" or 3/4" and as Lund did in many hulls was to build the hull, lay the decking and then build all other structures above the decking and actually used the decking for structural reinforcement. So w/o drilling all the rivets out of the hull to remove the helm, livewell, rod box, flotation boxes and another storage box I need to be able to slide the plywood out from under those areas and then slide the new back in.

Then in using this product my intention was to apply it the same way that everyone else is doing with the epoxy. To all sides.

I saw the product a year ago and went "OMG" what a great solution. Emailed them directly and they responded "will not adhere to fiberglass." You should do the same.

 

[bonz_d]

they responded "will not adhere to fiberglass." You should do the same.

What?!!!! I believe I already stated that.

This was discussed a while back on another thread. Consequently, My Daughter spent a LOT of money on this "JUNK" to "RESTORE" her Deck 2 years ago. She Power Washed her deck. Meticulously did all the prep work as instructed by Rustoleum (And ME!!!) and after the first summer of use it was peeling and popping off like Popcorn in a Microwave!!!! I wouldn't recommend it AT ALL!! I saw the prepped deck, the Primer put down and the Final Coat applications and can assure you it was all done "By the Book". If it does this on a Porch Deck, I can only imagine how it would perform in a boat. That's just this Old Dumb Okies Opinion, Others may Differ!!!

 

[bonz_d]

Sorry, I did not see that other thread or I would have read it. Thanks Wood I was hoping someone would respond that had actually used this product and what their results were. Question, was that the 10x or the 4X that she used? Do you think the problem is because of the thickness of this product and the way it is applied?

 

[kcassells]

What?!!!! I believe I already stated that.

Oh Yes you did, sorry. But who doesn't seal their deck? I misread.

 

[Trooper82]

I have used the 10x....been on the porch since spring....and the peeling has already started....never again....and never ever in a boat....just my two cents....

 

[Tnstratofam]

I'm glad people take the time to respond to these threads even when a subject has ben brought up before. I had seriously thought about using this product on my utility trailer. In the store the product looks pretty solid. Of course it's gonna look better there. They're trying to sell it. I don't know how well the decks I saw it on are holding up. They were at customers of mines homes, and I see them once or twice a year. I will be sure to pay attention to how they are holding up. Thanks for starting this thread, and thanks for the responses.

 

[bonz_d]

Thanks for the response Trooper. Guess if this stuff is that difficult to get put down and doesn't adhear well then I will have to reconsider use.
Looks like a nice product, guess it's too bad it doesn't perform the way they advertise it.

 

[sphelps]

Was thinking on using this over my cooldeck on my pool . But after Troopers and Woody's experience with it I may need to rethink .. It may adhere better to concrete .. :noidea:

 

[bonz_d]

I will readily admit that I am not a chemist or a coatings guy but I'd seen an ad and it caught my interest. It's nice to have a forum were we can come and bounce ideas. I'm not one that is adverse to trying new things or buck the system as it were. I was pretty confident that with all these members that there would be at least a few that have had experience with this product.

Thanks, everyone!
