    Can NA be used over existing plywood floor with old adhesive residue? I would normally ply over again but it will take too long and haven't enough time in the job, safety floor is to go over prep
    If I have to use a flexy screed which one will give best results?

    Cheers

    It's to go over residue adhesive from old linoleum, that's why I thought NA is the ardex flexy around about the same price as NA I Know it's not in the trade section so no prices:)

    You could add fibres to NA to make double sure !
    I think it would work a treat

    Ardex na CAN NOT BE USED OVER OLD ADHESIVE RESIDUE that is water sofenable. Lino adhesive is water sofenable.


    So no you cant use NA or any others i know of.

    What area is it. Its just as quick to ply and feather. Shorter drying time so get on with fitting flooring same day.

    I didn't know that & Ive had training at forbo but I suppose they where only teaching us how to lay it !
    So all Lino adhesive need to be completely removed before a screed is applied ?
    I always scrape up as much as I can of any adhesive but there's always guna be a small amount of residue
    What other adhesive fall in to this category ?

    almost all adhesives that are 1 part. All water based that you can wash off your trowel anyway.

    can you wash it off with water ?

    Or when its dry is it soft or does it become soft if it gets wet?
