GarageFloorGuy is right about many contractors getting blind sighted by some potential sale. However, the flooring contractor I mentioned here is hardly the type to do that. In fact, from what I have learned from working with Wolverine Coatings, most of their contractors are highly educated and committed to customer satisfaction. In fact, The pro floor coating contractor who installed the Wolverine Coatings Corporation products over the wood floor is well aware of, and extremely knowledgeable about, wood floors and coating them. Just as a quick background, the owner of that company has a Bachelor's Degree in Civil Engineering, he is a PE (Professional Engineer... kind of like a designation like accountants get when they become a CPA), he holds every certification you can get from NACE and SSPC, he is one of the few IAAPA certified engineers in the world, he also holds every designation by ACI (American Concrete Institute)... and... if that is not enough... his degree came from MIT. The guy is incredibly sharp and an expert who thoroughly researches and flat out knows his stuff. This certainly isn’t his first wood floor job, and won’t be his last.
Just as an aside, another pro who does large commercial jobs, and who has experience with all the major suppliers in the game, coated the wood floors in his personal residence, his choice for the job? Wolverine Coatings Corporation products.
Yes, a wood floor will expand and contract, not unlike a concrete substrate. If it gets wet, wood will probably expand more, fortunately a good epoxy coating will encapsulate the wood and keep it from becoming that wet, that’s one of the reasons to coat it to begin with. There are plenty of applications with resin over wood – pretty much every bar with a wood bar top has it epoxy resin coated, and a lot of boats have coated decks and wood work.
Is every epoxy suitable for wood application? No. But BondTite 1101 is, as is EnduraShield 2254 over BondTite 1101. Eric at Wolverine Coatings Corporation has developed AHC Technology which allows BondTite 1101 to do a few tricks a lot of other epoxies just can’t do.
Likewise although a lot of other epoxies are hard, but they’re also brittle, so they have very little tolerance for movement. Again, BondTite 1101 is not like all other epoxies. Even after curing it remains relatively flexible. This certainly helps on a floor when something is dropped on it, but it also helps on wood as it expands and contracts.
On this plywood floor you could v-groove or router a groove along the seams where the sheets meet, fill with IntegraFlex 1921, then BondTite 1101. Once the BondTite 1101 is down you can continue with the floor as you desire or just leave the clear finish although you would see the IntegraFlex 1921 underneath it. If you wanted a solid color look, just put down some LiquaTile 1184 over the BondTite 1101 primer and maybe add an EnduraShield 2254 clear coat. To reduce slip and fall potential, add a bit of SuperGrip 850 to the final clear coat. You may even decide to flake the floor.
