Hi am new on here. Go a customer who requires karndea laying on existing polished porcelain floor in a bathroom. As the tiles aren't porous is there a specific glue needed to do thus.
Use a grit primer and let it fully dry before the NA. You can use it without a primer but if they're polished then I'd take the extra precaution. I've sometimes scratched them up before to give a key
Thanks for that, I did contemplate having to put something on the tile first wasn't sure if there was a primer out there that would do the trick.
