Hi all, will epoxy work on a 3/4 T&G OSB attic floor. Very hot in summer and cold in winter. I'am planning on keeping my rideing mowers and such up there and need to protect my floor some how.
Thanks

yes - not an issue - think wooden boats, truck beds, etc. Lots and lots of folks have wood floored 'spaces' that need epoxy chemical protection.

note less coverage is the rule on wood floors , especially with seams and grooves. Note that 1 gal of any liquid only files 6 sf at 1/4 inch deep -

Depending on the flex of the floor. A lot of bounce will create micro cracking in the epoxy. You might consider crack chasing the joints and pre filling them with epoxy. Level out and let dry. Then go over the whole area. This will give a cleaner finish. You are going to loose about 1/4 of the thickness applied due to saturation into the plywood. If you are looking for just a protective coat then no problem. If you are wanting a nice finish, I would suggest applying 2 coats, first being a filler and then a clean final coat. Sand between applications. Not sure how tight the OSB board you are installing is but I'd figure about 100 sq. ft. per gallon on filler coat. Final coat will vary depending on how open the OSB is/was. I always suggest 3/4" (a/b) grade plywood or MDF board. Tighter surface finish.

I have used the one part epoxy paint from home depot on osb floors in my attic and in my tool shed where I keep my riding mower. It has held up really well and is only about $40/gallon. They can also tint it to whatever color you want.

Thanks guys for all the info.From what I can tell this will be more durable than using a porch paint.

Iam not worried about the look, just want to protect the floor.
So one coat should work using about 9 gal.

Pauloman Did you mean 60 sq. ft. or was 6 correct? I would need 150 gal.
for my 900 sq. ft.:shocking: unless you mean put it on alot thinner?

Don't cheap out on the epoxy. Use a 100% solids. You can go with a pigmented epoxy or, if the surface of the OSB looks good, consider a clear 100% solids epoxy. It will highlight the wood grains, textures and give an unique finish. Another thing, pigmented epoxies normally cost a couple bucks more on the gallon. Your call, Good luck.

Would your E100-uv1 be what I would be looking for?
Thanks

Not unless you have direct sunlight. If no unfiltered sunlight hitting it then our E100-PT-1 would be the best route. You know, since you are not out for pretty, We have an underlayment epoxy that is 100% solids at a real reasonable price. It has no clarifiers in it, so it is not "water clear" like our other epoxies..... and I would put them up with anything that is sold on hear for clarity. In fact the UL-7 epoxy is clearer than some of the epoxies being relabeled and sold here. It's really a small world out here guys as there are not many actual manufactures.

Here is the deal. It is only sold in 15 gallon kits. It is used mostly for quartz applications and for epoxy mortars. (We have our installers mix their own and not overcharge them for something so stupid as putting a little sand into the epoxy.....sheesh). Anyway, being just over $37.00 a gallon, it is one hell of a deal. Just saying.....

The E100-PT-1 series epoxy is $155.00 per 3 gallon kit putting it at $51.00 per gallon. The 15 gallon kit price puts it at $48.00 per gallon. The 165 gallon kit goes for $32.60 a gallon.
