Anhydrite or Concrete - dont know

[Dumbo]

That's expensive for what it is

looks like a screed layence has settled on surface like anhydrite i would sand off as this is loose and will not secure the adhesive or slr and must be removed before tiling

From what I have learnt over the past 48 hours that is also my thinking, its like some areas were wetter than others and its just pools of cement dust gone hard in those areas, if it comes off then I will take it off. Am I ok with the primer I plan to use, reason being its what the local supplier stocks

She got them at half price. So not the price on the website as they have gone back up now

all screeds whether sand cement or anhydrite have latence on the surface this is the water that comes to the top when tampering or trowing the product and should always be removed

If its barratts outside London and its a house it is probably self compacting concrete. Not only would it have laitance it will also have a curing agent on it. As with all screeds and concretes it should be mechanically abraded prior to bonding floor coverings.

For anyone who cares or was unaware or for future reference, the term "ceramic" can be confusing. We commonly know it as a glazed clay tile, but its also a description used in the industry as an umbrella term for any clay product that goes through a firing or kilning process, which also includes porcelain (glazed, double loaded, twin charged and full bodied), quarry tiles and several forms of terracotta.

As you were

I dont actually know what the difference is in terms of working with and I am still unsure why a previous poster said they were not suitable for the floor. And why choose a porcelain tile over a "normal one" as also am I right to think I will be needing a 8mm wheel for my Bellota cutter as it only came with a 6mmm and I have tiled a bathroom - floor to ceiling with that little fella

EDIT - just seen the
Tile water absorbtion experiment
so water proof is 1 reason to use porcelain over ceramic

 

[Filip]

Just received the box info dont know what that tells us but the tile defiantly says porcelain on the bottom

Size of the wheel is irrelevant so long as it is sharp.
