How to make wall tiles porous

Hi i would recommend that you use a different adhesive, you could use a good clear silicone quite effectively or something like Evostik contact adhesive, simply apply a coat of the adhesive to the wall tiles & a coat onto the back of the S/Steel sheet, allow it to dry 5-10mins & then lift the sheet into place on the wall. Once the 2 pieces meet though they will stick immediately and you wont be able to move it about, so check it is a good fit prior & maybe make some tap marks on the wall or the worktop to line it up, you could also use some 80 grit sandpaper to create a key on the ceramic tiles, but depending upon how strong the surface is it might not make any difference, hope this helps

Maybe get a ceramic drill bit and drill a few holes in them

you can get a paint to make the tiles pourous,but I would take the tiles off where needed then you would have a pourous surface to stick your stainless steel splash back too.hope this helps.marks maintenance services

You do not need to make the tiles porus, just use silicone as said,or use Siroflex grip and grab.
