Tiling bonding

[Gazzer]

No I mean the plaster was that dry coat stuff. When I asked him he said it was a bit like hardwall but was for damp walls. The guy seems to know his stuff all right

So basically you dont know what you are tiling to ??

A good reputation takes years to achieve, a bad one minutes and can last a life time.....Fail to prepare, prepare to fail.
Always know what you are doing and never take other trades word for it, when it fails, it will be your head on the chopping block, not theirs.

I had never heard of this backing plaster that's why I asked on here. When a plasterer gives advice (well the proper ones anyway) you know it's going to be good owing to the high skill level of their job

ive met many plasters that still think its fine to tile on to under coat gypsum plaster, there famous saying is 'just p.v.a it'......hence my sarcastic comment...

how big is this job?......and how long have you been tilng?, knowing about the correct primers to use really is basic stuff...

Waterproof adhesive ? Epoxy is it ?

Flexi ? Adhesive? No backerboards ? direct to timber ?

You really need to start all over and 1st question is....What is this plaster on the wall? If its a backing plaster then it is no good to tile to.

It's that thistle dri coat mentioned in that PDF u posted. According to the plasterer and your PDF I can tile it :mad2:

I'm just asking some advice guys

 

[Polishtradesman]

I tell you what Bungle. You call yourself tiler and ask to use PVA back of tiles. You want to use wood glue to tile and you call me rubbish??? I have never heard such an idiotic way to recognize someone skills. Your building knowledge is a rubbish.

From the PDF
Overview
Thistle Hardwall is a gypsum undercoat plaster for use on
most masonry. With a final coat of Thistle Multi-Finish, it
provides a smooth, inert, high quality surface to internal
walls. The combination has superior impact resistance, earlier
surface drying, a higher than normal resistance to efflorescence,
and gives a durable base for the application of decorative
finishes.

Tiling
Tiles up to 20kg/m2 can be applied directly to the Thistle finish.
If plastering to provide a background for tiles, avoid polishing
the surface. Polished plaster surfaces should be roughened
and a suitable primer used. Tiles should not be applied
directly to Thistle undercoats, with the exception of
Thistle Dri-Coat.

he proberly told you to p.v.a it as well !!!, if its bonding plaster then it needs to be skimmed..

I guess you know much better british building materials then me. However, skim is another coat and it is smooth. Thinking reasonably it is always better to prepare surface, using as less coats as possibly and it is better to tile non smooth surface then smooth. It is good tread, i learn onother thing with it, lets discuss.

You said it was hardwall...you didnt mention Dri Coat....2 different things ????

This is Dri Coat Broken Link Removed

I asked him what type of plaster it was and he called it that dry coat stuff. I asked him what that was and he said it was similar to hardwall plaster but for damp walls. He told me I could tile it, I suppose he didn't want to bamboozle me with all the technical plastering stuff.


I did say it was dri coat halfway thru the thread :mad2:
can I take it the plasterer is correct ?
