Primer now or just before tiling

[kiteboy]

Hi all

Hopefully have a tiler comming this Wednesday to make a start on kitchen tiling

Was going to prime today onto a gypsum screed with Bal APD but not sure if I should wait to just before tiling or not

Was going to do a 50:50 first coat today then maybe wait until the day before starting before doing the neat coat???

Would like to do it all now really so I know its done but not sure if it should be done just before tiling or not

Thanks all

Has the laitance been removed?

 

[kiteboy]

Yep.....had a pro out to remove the top layer for me

I would do the priming just before you tile. Allowing adequate time for it to dry which won’t be long with APD.

Apd is good to go neat on gypsum screeds. It's an excellent primer for them too

would i be ok to do the 50:50 coat now then the neat coat on the day the tliling starts

I would let the tiler do it, then he would be happy its done to his liking

Is the tiler using BAL adhesive?

 

[kiteboy]

No hes not using Bal.....i was going to say use that anyhyfix i think its called......so primer is less of a concern i take it as it wont attack the screed like a cement based adhesive

ufh?
uncoupling being used?
type of tile?

 

[kiteboy]

Yes ufh ......not uncoupling it......porcelian tile 600 x 600

 

[J Sid]

heating been commissioned?
screed been tested for a it being dry? By who?
why no uncoupling membrane? Your choice or tilers recommendation?

You shouldn't need to get so involved really If the tiler is competent he will take care of everything. Deffinately don't prime it as that could cause a discrepancy if anything does occur down the line.

Unless the tiler has asked you/shown you what to do u would leave it to him to prepare it

Warning bells are well and truly ringing if you need to specify materials and carry out the prep for the tiler.
Be careful!
