Hi everyone,
I have a quick question about a job im going to start.
I am tiling a large porch and will be tiling on tiles,do I need any special adhesive for this?
The porch is outside and the tiles are ceramic/porclain.
thanks for the help guys.

Just make sure you clean the tiles first using sugar soap make sure the existing tiles are sound use a brick and scour the existing tiles so the adhesive grabs the tile you can get porcelflex adhesive this is a 1 part cement based flexi adhesive for porcelain tiles that should be fine.Cheers Mick.

Mapei kerakwik could do the job, just depending whats available in your area

if its a floor use a grinder and rough up the exsisting tiles (alot), then sugar soap and clean thoroghly, and then use keraquick as suggested already by whitebeam...jobs a good en!

Ultratile were working on some addy for this last time I was in their lab. NOt sure if they have something available but may be worth a call

thanks for the advice guys,will take note of all your advice

bonding tile on tile is simple if done correctly - " if you can stick to the bottom of porcelain you can stick to the top of it !!! --- if it's clean that is !!!

1/. wash down with sugar soap to remove any laitence - ( not visable ) if this is on a floor, be very carefull it is very slippery.

2/. Mapei kerabond plus & isolastic

provided the original tiles are stuck, knowledgable adhesive manufacturers like Mapei & Laticrete have been doing this for over 30 years - no problems & they will normally warranty in writing if you need it --- Although Mapei are famously slow to put pen to paper over here lol
