Hi all, i hope your all having a good evening, i just have a few small question, i am tiling a shower, and i have had the room plasterboarded and plastered about 2 weeks ago, i was just wondering do i need to prime the new plaster...

What adhesive is best to use?
Which grout?
Where do i get this stuff from in Hampshire
Do i need primer?

How long do i need to let the primer dry if i do need it?

Many thanks

Hi...

This depends on what tiles you are using..

Im using 300mm x 200mm White Ceramic Tiles

My personal prefrence is mapei P9 cement based but for that size tile a D2t adhesive will suffice and most dispersion adhesives require no priming to plaster as long as you brush it down first....

The plaster and porous biscuit help the adhesive loose moisture....along with exposure to air...

Adhesive type will depend on size of tile Mosaic - travertine - porcelain -etc.
Go for fully waterproofed adhesive and grout and make sure the shower corners are sealed against cracking.
You may want to consider tanking the walls!
I always prime new paster walls to contain the dust and allow the moisture in the adhesive to grip both surfaces. The primer type should be discussed at point of sale with adhesive choice.

In Hampshire I would have gone to Tanrae tiling 34 years ago but now I suppose its Topps. Now in the North East you've got .............
