Tiling kitchen - painted surface, help! - TilersForums.com

[LJG7777]

Hi all,

I know this has been discussed previously but I need help with my specific job...

I want to tile in my kitchen between the wall units and the work surface. It's a new build so I'm sure it's plasterboard painted with magnolia emulsion. My tiles are 100x200mm and will be 5 tiles tall.

What would be the best way to go about this as I'm reading conflicting answers elsewhere? I don't want to fix a tile backing over my current wall for decorative reasons and am worried to sand the paint off as I'm assuming the plasterboard was painted directly and not skimmed over, i.e I don't want to end up sanding the paper underneath. It's too hard to remove and replace the current plasterboard as the units are attached through it and there are around five electrical sockets to deal with.

What would you do based on the above?

Hi.
so they are definitely not skimmed walls ,just drylined and emulsion? , is the paint matt and porous?

Hi, I'm just guessing that they haven't been skimmed however I wouldn't know unless I sanded an area to see. The paint is definitely matt emulsion.

Ok. Try and see if you can wash the paint off.

Just used a non scratch scouring pad from the sink, it came off quite easy. See pic - that is a skim showing through isn't it?

It does yes. Clean it off and leave to dry.
do you intend to use a tubbed adhesive or bagged

Tubbed.

Tubbed.

Ok , no need for primer then. Adhere to the drying times before grouting.
