Does anyone have a good recommendation for floor finish products for mechanical rooms that are slab-on-grade and also for composite decks above occupiable space? For slab on grade, I am considering either a hardener or epoxy/urethane system. For composite deck locations I am definitely looking for something that can also act as a “waterproof membrane”. Thoughts?
Brian,
The first one that comes to mind is by Dex-o-tex at http://dex-o-tex.com/products/WaterproofingDecking.
Look for the products with M-E prefix

I second Wayne’s post.
We’ve used the Dex-o-tex ME coatings often and even in mechanical rooms above surgical suites. Be sure to specify cove bases with the membrane running up the wall.
I will third the Dex-o-tex recommendation, knowing that there are many equals.
But above grade, you need to think beyond a simple floor coating to also include containment curbs and a review of the waterproofing rating of the fire-stopping solution you are using at the floor penetrations to build a complete passive barrier against OOPS!.
Traffic deck coatings may be considered as well.
Looks like we actually have consensus on something.
Any suggestions about slab on grade?
Steven - Great point about the fire-stopping issues. I hadn’t thought about that.
How good a vapor retarder/barrier is there below the slab on grade? Unless there is a positive vapor barrier, I’d stay away from epoxies, as they are moisture-sensitive. Also, both urethanes and epoxies can act as a vapor retarder, trapping moisture within the slab. I think your idea of a hardener is a better solution.
