    Screed & wet UFH issues.

    I went to see a floor on Saturday. Roughly 12sqm of screed with wet UFH in a ground floor extension. The screed went down last week. The surface of the screed was very rough and I could scrape up parts of it into my hand (very sandy). I could see and feel spongy insulation, as some of it was...

    Priming screeded floor

    I am looking at tiling porcelain wood effect tiles and wanted to use Ardex x7 onto a sand/cement screed. I called their tech helpline today to see if Ardex P51 should be used. The advise given was no primer is needed just clean floor hoover etc. Does this sound right?

    Anhydrite laitence removal

    Yes it's that damned gypsum screed! The builder assured me it's been sanded & laitence removed all bar one room. I'm on site today and they've got a guy using an electric hand sander with 80 grit paper. I don't think that's manly enough, how can I tell if the laitence has been taken down...

    What is the best adhesive to use for porcelain tiles onto screed

    We have around 50m2 of 120cm x 20cm porcelain floor tiles to lay onto 75mm screed. I understand the tiles should not be laid for at least a couple of weeks after pouring the screed and using ditra matting or similar would be wise. There will also be wet underfloor heating which we may turn on...

After around 50 days we comissioned the UFH...
