Browning as a substrate for tiles?

[mscg]

have been rendering up stone walls with BALS rapid set render -working out rather expensive! Is browning plaster a good replacement - its cheaper and builds up depth easilier. To be tiled to travertine afterwards - any views appreciated

No mate, The browning is,nt suitable. What about standard render 4-1 sand and cement would be a lot cheaper

 

[Gazzer]

No not suitable.

No, Browning/Bonding coats are unsuitable for tiling onto.
They are too weak, and too porous. They need to be covered with a finish coat before tiling to.

But in your situation, again, I think this will be unsuitable. The weight limit for plastered walls is only 20kg per sqm. It is very likely your Trav' will exceed this.
The other problem you would have is the drying time. There is a 4 week drying period before plaster can be tiled to.

Whereas BAL Quickset Render can be tiled after only 2 hours.

Needs to have finishing plaster on top to make suitable for tiling.

cant you dryline it ??

 

[mscg]

I could well do as there is a fair depth to make up in places - what board could you recommed given its got to hold 400 x 400 travertine? - I would have to dot an dab the boards

You're welcome, mate.



One more point, if you are going to go down the road of standard S&C render, you must leave it for 2 weeks minimum before tiling.
