Hi Guys
Hoping some of you can give me some advice on a job i have booked in for kitchen floor tiling.
The customer floor has had a self leveling compound (Mapei Restoration)laid down over the top of bitumen. Few concerns i have is that on part of the floor a hole has appeared around 100mm in diameter also the guy who laid it had come back on the customer request to redo some it as it wasnt level down one end of the kitchen.
Now the guy has over mixed it as you can see in the photos their was air bubbles in the mix also cracks have appeared.
Their is no UFH under the screed the screed i was told has been down for 6 weeks , other than the hole that appeared the rest of the floor does seem pretty solid. I was already going to put down decoupling membrane ie BAL or Ditra but i dont want to fix this down if the screed is not good enough and possibly needs redoing. Thanks

Arditex na is a great product . You will do no harm in priming and it will actually stop the substrate absorbing moisture so keeping it live for longer to help with the levelling .
