Hi all, I've been reading all the advice I can find on this forum over the past few months and it's been really useful so thank you! I'm planning on glueing down an engineered wood floor in the living room of our 1950s ex council house. I pulled back the carpet and found old marley tiles stuck down with black bitumen adhesive on top of a concrete slab. I've had them tested and they have been found to contain white asbestos. House has a dpc but is over 60 years old, had no problem with damp but have decided to put down a liquid dpm just in case. Decided to use Ardex products and have been in contact with one of their reps for some advice, they've recommended the following: Remove marley tiles (with the adequate precaution) scrape up any of the adhesive that's soft/sticky NA over the concrete and any remaining adhesive. DPM 1C R3E sand blind NA Glue down engineered wood after 48hrs Just after some clarification to whether I've interpeted their advice correctly and that this sounds like the correct approach. Anything in particular I should watch out for? Any recommendations for the adhesive to glue down the engineered wood over the final coat of NA? Ideally I wanted to use another Ardex product so that I'd know it'd be compatible but it seems like they no longer make their version. I'd really appreciate any advice.
