I have has converted the pergola to living room and end up now facing problem on the tile, as the original tile no longer in production (the house already 5 years old), and not able to find similar or nearest to existing tile

One option was to replaced all the tiles with new one and problem solve. But now my contractor was saying just lay it on top of it instead of hacking it away
1) The existing floor tile is very hard and difficult to hack
2) The hacking with take at least 3 days for the 430 sf area
3) Base on what he done and expirence some far (he already almost 50+) , that no problem and no complained even was bungalow.
4) As long didn't use China tile than no problem

I also checked with two tile shop, which also indicated that OK if the SUSU dont mixed with water, and i convert the message to him, and he indicated that 1) will put a layer on top (some glue type) and overnight 2) than lay all the tiles on top and not one sure step on it till next day. 3) It is OK to add water into the SUSU

Now
1) ANyone have expirenced than he / she house new tile lay on top of old tile?
2) Any advise on the SUSU issue ( Add or not adding water?)

This is small area that been converted



* I may raised this question somewhere on forum, hence sorry if it indeed happen

I remember i did that last time but is for my bathroom only. So far ok and nothing happen.

Get the right adhesives. It is due to the glazing on the surface of the tile that make bonding difficult.

Susu is white color latex based admixture that helps bonding. Check if he is sanding off the surface of the old tile?

basically is ok if not done on a flat or even surface.

eg: should hack flowerly marks on the tiles itself to have a rough surface and apply the suitable adhesive cements or mixture as the foundation before lay the news tiles over it. after flowerly marks was done make sure the floors is flush with water to wash the debries off the surface before lay the foundation and leave overnights. it may last longer and this is not suitable for crowded walkways for examples shops corridor........and etc

hack it off is always the best solutions.

i have mine done at bathroom wall..so far ok..2 yrs+

just wanted to ask whether retiling over existing tiles is ok for wall tiles as well?thinking of redoing my kitchen wall without hacking to save time....wonder whether it will drop off after a while...

I'm endup paying another tile specilist to do my job due to
1) Expirence: Tile over tile can't work on 2x2 due to the edge design
2) may not be balance and may injure the leg
3) Need really expirence sifu to do it, as it may other problem such lke tile pop up which will impacting the whole Floor
4) 2 x 2 tend to impact of whether, as accoridng to the manifacture lot of people having such problem, may cause tiles pop up.

Hence after get the specilist advice and price seem OK. I put the job from existing contrctor and hacked whole kitchen / living room tiles out.

My tiles sifu tell me ...the ONLY reason the contractor want to lay over tile is ..SAVE WORK and TIME for them...
owner will regret few year later...

the tiles will pop up, cause my friend have facing this problem. dont care about the sifu... all they just think to save their own.

Also, a advise given was for those 2x2 tile, you need to put a layer on the tile itself (Susu + cement) and leave it at least an hour or a day, than only put into the floor...
but it need to pay extra or you has informed / discuss before hand.

Hi there,

Technically speaking, it wouldn't works.. Reason being there is not holding grip between the old tiles and the new tiles...

Added on June 9, 2011, 8:47 amHi there,

I not too sure what actually u mentioned here, but from technical point of view (CEMENT + SUSU) before laying is necessary...

Just some hints when you speak to your Tiles Specialist, are they laying in DRY-Method or WET-Method.

The cement sand base @ screed most be done properly with all level well indicated. For better outcome, the moisture content of the base screed most be as low as possible.

For 2' x 2' tiles, the real way of laying was to use Teethed Trowel method instead of Butter Method. But I have not seen anyone in Malaysia using this method as far from my past experience.

For 2' x 2' tiles, try to get those reliable quality tiles. Just my own experience, my tiles crocked after couple of years due to in-stable moisture content and atmospheric temperature.

sl2007,
you seems to know a great deal about tiles and tile laying.
there are some tiler who uses teethed trowel method but pricey lor. and i obviously prefer dry method of laying. you got any good tilesman to recommend? planning reno in aug.
planning to get guocera wall tiles and mml floor tiles.
thanks.

no problem for that area. ive done it on a 15m long corridor before. heres wad they shud do. pour susu+adhensive cement 10:3 n make the surface coarse using trowels or just broom. leave it over night. make sure the new floor height isnt too high as the screeding might be a problem if they mix in too much sand (might be too hollow) if its just directly on top of the old tiles, it shudnt be a problem with the right cement mixture used.

Hi there,

Thanks for your compliment.. Let me check for you, actually I just back from oversea.. So majority of my contact "cabut" order.. Hahaha

A) the base or original tile must be done in proper workmanship.

B) the mixture u mention doesn't seemed to follow any reference Standard.. (e.g BS, ASTM or etc)

C) I'm sure u need to form some key on the original tiles prior laying the new layer of screed.
