Fixing to Calcium Sulphate Screed & drying times

[Cat]

Ajax - after reading your post with your obvious, indepth knowledge of the science behind the substrate - yes, PVA does sound a bit Heath Robinson. Have to move on and not worry about this advice or I won't sleep at night!

But a tiler should always check for laitence, don't you agree Ajax..?:smilewinkgrin:

Hi Dave - I have read the floor finishes advice from some of these companies found on google - and it does mention polyurethane or acrylic primer. I can't get any joy from my screed company and my tiler is really trying to find out as much as he can from lafarge etc but as self builders we need to really be happy with our methods ourselves also.

Thanks for your help. Cat.

loos like these peeps did>>>> lafarge gyvron calcium sulphate company.

Negative good buddy - I know for a fact that this particular organisation would not recomend PVA. (assuming spelling error on Gyvron of course otherwise I in trouble)

Broken Link Removed

I am guessing ready mix supplier - would be interested in knowing whom.

Thats what i thought...thats who you work for isn't it..?..thats why i hoped you seen this and corrected who advised pva ffs...


The question now is getting this floor prepped and tiled correctly...

Cat..get your tiler to join our forum and then the info can be given DIRECT to him so he can absorb it at first hand...

Hi Ajax - not your company at all so no worries there. Obviously not going into details - guys were great - screed is great - floor is flat - just need to get the 'bloomin tiles stuck to it...

Absolutleytootley Dave.

BS8203 - code of practiv for resillient floor coverings

"the screed should be sound, clean, dry and free from dust and contaminants likely to affect adhesion of the flooring"

ergo Laitance should be removed prior to the application of tiles. If no laitance is present there is no need to remove it. - Screed might need sanding for other reasons of course e.g. removal of mortar or plaster snots, plasterboard addy, expaning foam deposites and such likes.

did i attach that pic correctly - not sure

Hi Dave - yes, agree just need to get the solution now - on my recommendation my tiler has been a member of the forum since I joined a couple of months ago. As a self builder and project managing, I need to be sure that everyone is happy with the plan - if I've managed to get the house up I'll get the floors down! I'll be collaborating with the tiler and I'm sure he will get involved in the thread when I speak to him so that we all know the best route.

Cheers, Cat

I wish to remain silent on the grounds I might incriminate myself - thought it was supposed to anonymous

but seriously if it helps the industry get things right I am happy to help cos Anhydrite Screeds aint going away (not if I have my way anyway)

I agree

Cat..get your tiler to join our forum and then the info can be given DIRECT to him so he can absorb it at first hand...

good idea

Ajax - thanks for the laitance pic - no, my floors didn't have a skin on like that and are all smooth and clear. Really useful though to have a picture - makes all of these terms come to life.

Cheers, Cat
