Hi, am thinking of overlaying my 4-room kitchen & toilet wall/floor tiles.

What type of adhesive will my contractor be using or should I look out for?

Does he need to hack holes in the walls for what he said is "stronger grip" for the tiles? If so, does it require any permit from HDB?

Thanks.

The wall needs to be roughen or splatter so that there is grip for the adhesive and the tile. There are a lot of brands in the market, don't really know what is a good brand. It is workmanship also.

Oh..so that means need to roughen walls. One of my friend told me if hacking then need permit cos noisy...but overlay don't need permit. So does roughening walls need permit?

Thanks.

I do not think so roughening of walls needs permit. You can check out the hdb website: http://www.hdb.gov.sg/fi10/fi10324p.nsf/w/...ng?OpenDocument

Or best check with your Reno contractor, he should know best.
