Rough plaster

[brendanbreeze]

Hello all

Very new to tiling (recently done a 4 week course) and went to price a job up yesterday. It's a small bathroom and the guy wants all the floor and walls tiled. The walls have recently been plastered but not to a smooth finish, in fact there very rough. The ceiling has been finished perfectly smooth as I'd expect. The guy who done the plastering knew that the walls were to be tiled so is that why he's left them as they are?

I will have to smooth it down in some places as there are some lumps that would be impossible to tile over. This is not a major problem but just wondered if this type of plaster finish is ok to tile on? I hope I've explained myself well enough. Cheers, Brendan.

It is rough or is it uneven, It should just be ruff surfaced to give you a good key, if plaster is too polished youd find yourself having to sand the surface to get a key, if its uneven however so much so that you wont get a level finish then maybe more work needs to be done with it.

By the sounds of it the plasterers left the ceiling smooth becuase he knows its getting painted and the walls rough to give you a good key as he knows its getting tiled.

Thanks for the reply.

I hoped that would be the case. but it ireally is pretty rough and just looks like it's been done in a hurry. I guess it is un-even too, especially round the window reveals and will definately need sanding down all over as I ran my fingers across it and small grit size pieces were coming off.

do you know if it is a sand and cement or a gypsum basecoat?

No disrespect to plasterers but never tell them it's getting tiled....:lol:...the phrase OH!! the tiler will get over that with Xtra adhesive...:mad2:

 

[brendanbreeze]

not too sure really, but it's dried to a kind of pinky brown colour.

it sounds like bonding plaster, in which case, it is not suitable uneven or flat to tile onto. See if you can find out the substrate for definite
