T & G vs. Regular 23/32 Plywwod

I'm not a carpenter but I am pretty handy. I poured a concrete T foundation and I am installing a 12X18 Ft floor over 2X8X12 Floor joists spaced 16" on center. I bought 9 sheets of 23/32 4X8 plywood but I'm having second thoughts because everything I read talks about T & G subflooring. Can I use the the standard 23/32 X 4X8 plywood or do I need to use 23/32 4X8 T & G Plywood ?
Asked by: Orca
Better water resistance, stain repellant, more rigid and can be used without 'squeaking' up to 24 OC joists. My current project is a 112 year old Craftsman style farm house and barn etc. this is the only exception (other than required code materials) where we are not using the original materials refinished. The original pine planks had long rotted and been covered with six or more layers of flooring and pressboard or plywood adding up to almost 4" thick of declining floor needing removal and replacement. The 24" OC joists are sound and our choice of 23/32 4x8 Premium T&G so far is the right choice for a heavy radiant floor heating system and 3/4" bamboo hardwood and period tile flooring and fixtures. But be sure to use ring shank nails AND a quality construction glue to be sure it doesn't 'pop' and start squeaking during expansion and contraction conditions. We see -20F to +115F deg around the seasons with severe winds so we think about everything!

how well will this resist moisture in a kitchen setting. Yes it will be covered by linoleum.

is this water resistant
Asked by: Fishy
Product is probably too rough under linoleum\sheet vinyl, would telegraph texture and seams through the sheet goods.Seams have built-in gap to allow for expansion. Would need to be skimcoated or covered with lauan. It is designed to be subfloor material. Moisture resistance would be similar to OSB or ext. grade plywood.

Can I ceramic tile directly to sheathing

Asked by: Rb
I installed tile directly to ext. plywood that was nailed every 4" and in the 20+ years that passed, never a single issue. NEVER. However, this product is NOT plywood as some call it. If the glue in this is not ext. then do not get it wet.

Rated 3 out of 5 by from Compared to Advantech This product comes up on the HD website when you search Advantech. Granted it does not say it is the Advantech brand, it is clearly suggested that it is at least comparable. The 'Pro' at the store actually said it was the Advantech product. I would agree with remodel1, it is not Advantech. It is not water resistant treated with waxes and resins, the chips used in the material are larger that those in Advantech. Smaller chips lend strength to the product. I was using it for the floor in building a small workshop, which will be ok. I would spend the extra $5/sheet if putting it in a house, especially for hardwood. There doesn't appear to be $3/sheet extra quality between this premium T&G, and the non-premium(grey edge).

Rated 3 out of 5 by from not advantech I was using this stuff right beside advantech this stuff did not lay is flat was not as strong of is stiff . I try to use a crow bar to remove a nail that bent when I got in to a floor joist went I pulled on the bar it went though the premium subfloor I could not believe it. Next time it will be advantech.
