Tiling on skimmed plasterboarded walls

[Hulloo]

Hi, im tiling one feature wall in my bedroom. The wall has been boarded and skimmed. it measures 2.35m high x 3.6m wide. the tiles measure 50cm x 17.5cm. What would be the best way to tile this (i.e priming and adhesive etc....). it is NOT a shower wall or in a moist room or have and water on it. please advise thanx

What are your tiles made of? It's worth bearing in mind that the maximum recommended weight for skimmed plasterboard is 20kg per m2.

they are ceramic.....and come in a box of 15 which covers 1.31 squared meters and the box weighs 26kg...

Assuming your wall is all over the place as its been skimmed there will likely be high and low spots so you will prob have a challenge getting the tiles flat! Having said that mapei kerraflex maxi allows adhesive bed not exceeding 15mm so this will give you half a chance if you a very good diyer! And prime with acrylic primer first. Most importand not to exceed the weight limit of 20kg pm2 for that wall though!

A bit too heavy then by the time you factor in adhesive. You could remove the skim for more hanging strength.

what a shame you had it skimmed , plaster board is a much better surface to tile and takes a lot more weight

Thin ceramic! How straight is wall?

quite straight.............

 

[charlie1]

Quite straight? Over 1800 level how much gap can you find? Are the tiles ceramic ?

If answers are ... Hardly any (2-3 mm) and yes then I would prime with acrylic primer then tile with cement adhesive!

Why do you assume that.....

Generally up here the plastering work can be very iffy in my experience, if I go to a job and informed its been plastered I really do expect the worst! Is much rather do my own prep work

I'd use a slow setting adhesive such as Adesilex P9 and prob an 8mm notch trowel. Once you've put a couple on, pull one off to check you're getting decent adhesive coverage. If not use a 10mm notch trowel. Prime first with Mapei Primer G, NOT pva.

your tiles/addy/grout will take you of the weight limit.a slightly thinner tile would be ok.
