Tiling on fresh one coat plaster

[smith_21]

i want to skim my kitchen walls with one coat, as the surface is bad, how long realistically should i wait to tile with 200x100mm johnson tile, people say at least a week, is a week minimum

In my experience there is no set time for leaving new plaster, depends how thick it's put on and the temperature in the room. It will be obvious from a visual point of view when it's dry. As it's drying out it will start to look patchy, just wait until all the damp patches have gone and it is a consistent colour.

Rule of thumb is 1 day per mm, but that varies on temperature etc, as said, you'll see when it's drying / dry.

If its to tile on, how about skimming with a bit of rapid instead?
2-3hrs and you're away

Its all been said above really, you should be able to see when it is dry by the colour of it. If you have the choice, leave it as long as you can to be safe. Good idea above, if its a small area using a rapid set powder adhesive to skim the walls could save you a lot of waiting time.

what's the point of skimming on the tiling area? And if the surface is that bad are you sure it's suitable for tiling?

I was thinking the same thing.

If practical, I actually replace plasterboard prior to tiling.

If it is a solid wall, you could skim the area to be tiled with rapid set as suggested, or if it is sound, level but just not looking great and would hold the tiles just tile over it.

I have actually rendered walls specifically for tiling before now. On one job where I was renovating a house I stripped out and re rendered a whole wall in the bathroom that was to be tiled floor to ceiling. I didn't skim it as any tile adhesive will stick like wotsit to a blanket to the wall.

4 to 1 sand cement render with lime if the wall calls for it - works a treat. Level off with a good straight edge to make the tiling even easier!

I just use a plasiciser for adding to the render

It is called making good to tile too..ffs.. what all tilers do when a substrate isn't flat enough to tile too... but not with a bonding coat...

One coat is good stuff for squaring up walls ive used it quite a lot with no probs but i wouldnt use it any wet areas as i wouldnt any gypsum plasters remember it needs priming if you are using bagged addys.
