Plywood or Advantech?

[COACHJEFF]

I build houses and love advantech for my work. We sank a peice into the lake for 6 months and could have used it on a home. I wonder what results would be if we had removed allowed to dry and resank many times over??? My original question is truely motivated by my lack of KNOWLEDGE reguarding camper floors an marine plywood. I
want to use the right product.

I don't think I would use AvanTech

Q. Can I paint AdvanTech subflooring and sheathing panels?
AdvanTech panels can be left natural, stained, varnished or painted with oil or epoxy based paints or oil based primer and latex paint. Water seal is not recommended. AdvanTech panels are not recommended for exterior siding or other applications that are permanently exposed to the weather.

Please someone sell it to me! I have to buy subfloor within a week!

I believe this applies to the sheathing and not the actual subflooring since there is only reference to the sheathing. I laid 2 layers of oil based paint over mine and had no issues.

I guess we will all know which material is the correct one in 40 years. 2 years is not a proving ground and either is 10 for that matter. When Airstream started using chip board as it's floor I doubt seriously that they ever dreamed it would fail like it did. They used it to save money on construction and it came back to bite them, big time. Having worked in wood most of my adult life, I have incredible doubt as to the use many of you are putting this product to. You can show me studies all day and night, but there is no way that compressed, chopped up wood is going to out preform cross laminated plywood sheets.
Time will tell for sure who is right. I would hate to have to redo it all just to save a couple hundred bucks today.
This thread has run it's course for me. I hope you find the product you feel comfortable with. Good luck to all of you with your floors.

Cool. Did you get the meranti like Frank suggested? I tried to get it when I purchased my flooring, but none to be found.

just to add. Meranti is a tree like fir or oak. It is a tropical mahogany though it is not a true mahogany species. Luan is a very close cousin. Many know luan as underlayment for vinyl flooring. Meranti is used because it has very straight fine grain. There are other species of wood used in marine plywood. Oakum is the most common one used. Beware or the splinters in meranti. They are very easy to get and will begin festering within 8 hours

CoachJeff, you made the right choice!! Like I told you in the PM. I have sold and used sheathing products for thirty years and a good quality(A/C) douglas fir plywood is the best product for your application. OSB is OSB--some mills put more glue in it and the rest is MARKETING!!!!
