    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.

    Anhydrite screed & Laitance removal

    We had a 50mm anhydrite screed down over a DPM around 100 days ago. For the first 50 days the conditions were far from ideal for drying @1mm/day (early Feb, definitely no where near 20 degrees air temp, fresh plaster throughout, room open to elements). After around 50 days we comissioned the UFH...

    Tiling onto a concrete screed, but there's a crack by the door....

It also sounds pretty hollow. I know I could...
