I am considering moving into my cousin's old trailer but would like to take out the old carpeting and floors which are a little gross... i was considering using vinyl tile throughout the entire house (i'm not a big fan of carpeting anyway) but was surprised at how expensive the project could become... i found a very nice commercial grade tile (the type you'd see in hospitals or schools) at a really great price, but it isn't self-adhesive... i'm prepared to do the work, but i need to know if it is safe to use the adhesive on a pressed wood floor... what are your thoughts?

by pressed wood i'm referring to partice board... i'm not sure of all of the technical names for things, but the wood is the kind you'd find in those furniture kits that are laminated, not the kind of wood with large chips... please educate me on the proper terminology...

install 1/4 plywood first.

There are several types of composite and fiberboard.

medium density fiberboard (MDF) is made of refined fibers and is often used in furniture and mouldings. It has an extremely smooth sanded surface. It is paintable if primed and is often veneered.

Particle board: looks like granules of wood the size of kitty litter all glued together and pressed. Very heavy, not structually strong. In furniture we call it explodoboard. Tends to be absorbant. See a lot of this as underlayment because its cheap, but it does not hold nails well and can't be used for hardwood floor. Mastics work better if not aqueous mix.

Oriented strand board OSB: wafters glued together. Used for sheathing, roofing and subfloor. Tends to be too rough for underlayment and does not hold glue well. Need to apply plywood or luan underlayment on this.

Hope this helps.

of the different types you listed, it sounds most like particle board - looks almost like large pieces of sawdust... so you're saying that i should be able to use a mastic on this and then apply the tiles???

Particle board accepts most mastics and adhesives well. Thin water or solvent based mastics can soak in and be ineffective. In the case of contact cement, just pre-coat the board, allow to dry, then put the adhesive coat on. Thicker mastics (ones applied with a trowel rather than a brush) do not have a problem. Adhesive on particle board can fail because the board is actually weaker than the adhesive, but for a tile floor, this is not a problem. Be sure surfaces are clean, use no water, pre-seal in the event the adhesive is thin.

after doing a bit more research online i'm seeing more and more people discouraging the use of vinyl tile on particle board... i'm getting nervous... i'm wondering how nice sheets of plywood would look if sanded, stained and treated... is that even a possiblity for flooring, or would it look horrible??? is it even possible to attach plywood (perhaps a luan or something) to particle board??? i'm afraid to make a move in any direction without knowing that there is an option that would work without a hitch... (p.s. i really hate carpetting)

1/4 multiply would be best.

stain it! might look good!

some cork floors look like OSB!!

now you've got me thinking... i never thought of using OSB, but that could look really cool as a floor... you probably wouldn't be able to stain it, though, could you??? i think i remember hearing that OSB was treated to be waterproof... is that correct???

we're ripping up the carpet in the house today and i'll find out exactly what's under it (though i'm sure that it is particle board all the way through)... i've decided that i'm going with the vinyl tiles, so here are a couple of last minute questions:

which would you recomend? luan or plywood? ins and outs with each?

how do you apply the luan or ply to particle board? nails? screws? is there a pattern to follow?

if i find out that there is vinyl sheeting under the carpet (a real possibility with mobile homes) should i take it up or could i apply the luan/ply directly over it?

i'm getting excited!

plywood the whole way, Luan is cheaper, but you get what you pay for...let the big box stores use the Luan.

Yes install the ply over the existing (possible) vinyl.

not sure exactly how to set it.

I agree plywood is superior to luan. Attachment would be with liquid nails floor and subfloor glue reinforced with either screws or ring shank nails.

I'm a little puzzled why you are not considering a laminate for this application. It could be floated on an acoustic pad without worrying about attachments and underlayments and there is a lot of variety. Also, look closely at the particleboard. It is most likely an underlayment, not a subfloor. If it terminates next to walls, cabinets and doorways (i.e. does not run under), it can be removed and replaced with plywood. But laminates and floating floor applications are by far the easiest.

well, the vinyl didn't go across the house, and most of the floor is, in fact, particle board... i'd really like to ask the differences between the luan and the ply... why would luan be so bad??? my budget is getting smaller and smaller and am already paying quite a bit on the tiles themselves... i'd hate to make a mistake using luan, but i'm not sure if i can afford the plywood... could you tell me the ins and outs???

thanks!!!

Luan is not a structural board, but is made with a very smooth finished face that will work well under vinyl tile. The alternative would be A-C plywood, and you are right, the costs (3X greater for plywood) are not justified for the difference in quality.

Is plywood better? yes, because it has structural qualities.

Will you ever notice the difference? no, because you will get a smooth finish to lay the vinyl on, and the structural difference between 1/4 ply and luan are insignificant.

Good luck on the project, it will work out fine.

okay - to catch you all up...

i've decided to go with the luan - there is no telling how long i'll actually live in this trailer and also, well, it isn't my trailer... i don't have enough money in my budget for plywood, and i'm not worried that the immediate results will differ too much...

BUT more problems arise:

after pulling up all of the carpet (and boy was that gross) i discovered two problems in the particle board flooring: the bathrooms... these people were morons for putting carpet directly over particle board in bathrooms... well, one of the bathrooms is not so bad... just some damage along the edge of one wall... the other, however, has a large area behind the toilet that is sunk in a bit... i'd say that the level in the "sink hole" is about one inch below the rest of the floor, but definitely not any deeper than that... it's crumbled a bit... looks like there must have been a toilet overflow at one point... so, the question is: is there any way to fix this before tiling since i'd imagine that you can't put tile over a floor that isn't level... again, i plan on laying the luan over all of the particle board... is there a way to level it under the luan??? i'd almost like to replace that particle board in the bathroom with ply or something, but i have ABSOLUTELY no idea how to do something like that... please offer your suggestions... thanks!
