Removing tile adhesive from a concrete slab.

    Howdy.

    I am in the process of tearing up the old tiles in my downstairs. For the most part, the adhesive is coming off the slab fairly handy but the hallway was better bonded.

    I am using a scraper and a kango.

    Anybody any experience on this though ? Arms are in bits from scraping the slab and it's a dusty affair.

    Would boiling water do anything to the bonded adhesive on the slab?

    More detail might help. Ceramic/quarry/porcelain or vinyl tiles? What are your plans?
    If you're retiling, maybe putting down some self-levelling compound might cover up the adhesive traces.

    A wide bolster chisel and a lump hammer?

    Ultimately what happened was that a shoddy job 8 years ago has lead me to this problem.

    Slab was a new build home. Adhesive used was sub par, grout space was around 1mm and they were tiled UP TO the skirts and consequently I came home one evening in November to two tiles in the kitchen "tented" up on each other. I cut their grout out and removed the tiles and once I did the entire floor failed. Years of pressure built up was released and the tiles all broke their bond with the adhesive.

    Got a few surveys done and result was the DPM was fine, house was clear of pyryte and blame was laid on the adhesive.

    So I've removed every single floor tile now. They were cereamic. Most of the adhesive is brittle and is coming away handy enough but the hallway seems to be a different batch and is well bonded to the floor.

    Plan is to scrape the concrete back to build condition, prime it and re tile the kitchen / hallway.

    WIll those machines make short work of the adhesive over a kango ?
