    When Ive stuck down engineered wood in a room where 1 half is concrete and the other is floor boards I put down 6mm ply and latex up to it.

    If im fitting solid oak wood block would I need to use a thicker ply? If so is there a better method than ply and latex?

    Dont think thicker ply is needed, how thick is the solid wood block?

    Havnt seen it yet but Im thinking it will be 10mm or 15mm? I need to put a dpm down first over the screed but wanted to make sure 6mm ply was suitable for solid wood block. Havnt stuck down solid over timber for as long as I can remember

    6mm is fine.

    i would suggest you plywood the wood section and then do a full screed over the wood and concrete section with Fibre reinforced screed.

    Would you do that in 1 screed or build up to the ply first, then flexable over the lot?

    Is floating it not an option? Ive floated a few solids after much debate from the companys who make the flooring. Alot of them are recommending floating with there solids. What does the wood gurus of the forum think?

    almost all failed solid wood floors we see are floated.

    Its not a recommended method of install in the u.k.

    Should give you a idea, sometimes you can do it one. Other times in 2 lots.

    I dont like floating solids anyways but this is wood block so it needs to be stuck, sanded and finished mate. Just wanted to check on here if there would be any problems with the strenght of the ply under solid wood block or if the movement over different subfloors would be an issue.

    what kind of failure? Only ask because personally i think solid wood failures is down to poor/wrong installation, usually joiners doing it with there paslodes. :lol:

    normally gapping and broken tongues etc.

    Dont get me wrong, it is possible to float solids but i would recommended you use a underlay system, like elastilon.

    Solids just have to much movement over the seasons that normally can break down the pva etc.

    cool, i dont float anything over 15mm thick, its basically a last resort when cost/time and subfloor issues are too great.
    This is an area that can maybe be added to the customer section, knowing the product that your planning on buying. Pros and cons of wood,laminate,lvt,types of carpets etc etc.

    fLOATING SOLIDS ARE POSSIBLE IF THE SUBFLOOR IS DEAD FLAT.
