Tile on painted palaster skim and laminated wood

i searched and found an answered thread

we have a dot/dab plaster board and skimmed wall behind a sink on a worktop and each side are laminated wood end panels
NOW my wife painted all that earlier in year - BUT now she has got some tiles - just 150x150 cermic mat , and we are only going up 1 tiles -
along the plasterboard and out eachs side on the laminated end panels

I was going to get some SBR and then i though OH its been pained and laminted and so what now

I guess i need to rough up , maybe sand to get the adhesive to grip
we have some
Mapei Waterproof Fix & Grout Tile Adhesive

its only a utility room so not a big deal (although its getting that way now)

Now as a tiler, I would normally never support such an unprofessional act as using tile adhesive as normal on the skimmed wall, and use “ sticks like sh*t ” ( other grab adhesives are available. ) on the back of the tiles that are landing on the end panels

oh wow THANKS - i can take the adhisive back then and use pgb (ct1) or ?
i also have to put a black trim around

what as an unprofessional act , sticks like sh*t ” is that any good, i used years ago for some wood onto a concrete floor and it was useless

4 tiles on both sides on the laminate
and the rest across the back, so also on the plaster board

Use the tile adhesive for the plasterboard
Use a grab adhesive for the laminate

Ensure you leave the spacers in for long enough for it cure/ dry before removing them.

Use the tile adhesive for the plasterboard

Probably a side effect of a problem with surface prep; i used the same onto an anhydrous screed rather than mechanical fix, to ensure I didn't hit any underfloor heating pipes in the screed, and it worked a treat.

SticksLike is my go-to construction adhesive these days. Awesome stuff

Have also seen hot melt glue used to good effect in a similar scenario

I'd tickle it with a grinder and a diamond wheel, just to rub through the paper/paint and expose the plaster core, rather than tile onto painted plasterboard

I certainly wouldn’t be taking a grinder and diamond wheel around the top of my worktop and behind the taps.
For one row, ( of lightweight ceramic tiles) only 6” high, if you must take some paint off, I’d just scratch it with a 6” piece of wood with a few screws put through it to make a ‘scratch comb’.

( EDIT : just take the adhesive back and use the ‘sticks like’ for the whole lot )

thanks - we sanded down the whole thing - and also have some adhisive - so will get some "Stick like " thanks

Yes it isn't the first time you've made public declaration of your competence level with that particular tool..

The main point was a recommendation to abrade the surface rather than tile onto painted board, and not specifically that one must use a grinder to do it.
