Anhydrite Screed Tiling

Crazy price! I can get them for about £12 on ebay. make your own box from wedi / kerdi board. Save a packet!
 
I would prime all screeds personally. I agree from a compatibility perspective anhyfix does not cause an issue but it will help act as a dust suppressant. Prime plus or similar diluted 2 or 3 to 1 with water. Leave overnight to dry and tile. No need for ditra .
 
How did you get on with the unit? I am thinking of buying the same one. Just started a new thread with C/A screed issues.

I decided to make my own in the end and followed the advice and it worked a treat. Think all in cost me £30 so was worth the risk. Must be a massive mark up on these units for what is really a very simple design. Will post some pictures when i get a minute
 
Firstly have you removed Laitence so floor looks like sand and cement screed opposed to the power float effect it starts with ?
If so there as previously stated no need to prime with gypsum based adheshive as it doesn't t react with screed as cement based does ! But I'd give it 1 coat 1-1 with water to stop it dusting up whilst working on it !
If you are unsure of moisture content the screed supplier can come out and do a carbon bomb test and that's final !!
The digital hygrometers aren't as accurate I've invested a lot of time and money on a floor grinder and associated kit to prepare these floors and have done quite a few up to 300m2 total ground floors ! Good luck and enjoy doing it ! Dave
 
Anyone got the link to thread about making the boxes? Think it involved routing out ? I’ve got two of the units and need to make the boxes, I don’t own a router
 
@impish would be the man for that I think.
I didn't route anything. As long as you use 10mm board, just cut (or drill) a hole to suit the stat and seal it in with something suitable.
Just make sure you don't gloop up the holes in the unit with sealant as you'll wreck the measurements.
 
Any specific dimensions required ? I’ve got some 10mm board and some ct1 I’ll get them knocked up this weekend
 
I made these 3, in a hurry as you can probably tell! I've tested them along side a couple of F Ball ones and they read exactly the same. They cost about £15 each, the backs were hacked out with a router bit in a bench drill

You must seal it to the floor using a water free system such as poly butyl tape. Don't use Silicon or decorators filler

Is that because it gets a reading off the moisture in the Silicon ? Anything else you can other than the tape ?
