[mikedavey]

When i went back the next day i touched one of the tiles & it just fell off. I was horrified & was really wooried all the rest will fall off very soon. What did i do wrong? I'm having to use no more nails now.

Can anyone help me please?

use mosaic fix for them...or white star...in future backerboard is better than plywood.....Gaz
BAL Mosaic-Fix Tile Adhesive

Are they porcelain tiles

 

[mikedavey]

No, they are ceramics

Never heard of Bal Bond or Blue Star
When tiling onto plywood I always use Mapei Kerraquick - cementious flexible adhesive. Never prime. Never fall off. You shouldnt need to prime plywood if using flexi - think that is your problem

balbond sbr aids in the adhesion process..it is the blue star or the tile type to blame here....me thinks..

Blue star is not suitable for plywood....Gaz

 

[DHTiling]

exactly gazza................white star is good for ply on walls etc...but if its porcelain then switch to powdered flexi gear.spf...

throw the ply away make it out of plaster board

A good tiler will always make sure that he is familiar with the products that he uses and their limitations. All manufacturers supply technical specifications for their products. Most manufacturers have a technical helpline if unsure.

I've almost finished the whole job though........Is it a matter of time till the rest fall off?

 

[Perry]

how well fixed is the panel and what size ply ? havent used ply on bath panel for 20 years it doesnt work very well

 

[mikedavey]

I only used ply as it had ply fitted before. I replace it cos the old piece was ruined during removing the old tiles. I screwed it approx every 300mm along the lengh, top & bottom of the panel.

 

[DHTiling]

how thick is it mike...

 

[Perry]

how thick was it 12 mm ?

what the ply Dave

 

[Leatherface]

Always preferable is "No More Ply" cement based board.
Very rigid and only 6mm thick

 

[DHTiling]

[Perry]

It may be because your adhesive was drying before you got to put a tile on it. As a rule, only spread enough adhesive that you can cover with tiles in 30 minutes.

Also, from time to time, stir your adhesive bucket to keep the top of your pot nice and damp..... (no innuendo's please....lol)

Dave it would be cheaper :lol:

[CptPugWash]

or do a runner :ninja:

 

[robbo]

If you are using Bal products go to the www.powerspeconline.com it will tell you what Bal products to use on the substrate you have.

Blue star would have be fine although not ideal as white star or D20 would have been better.The problem has stemmed from the application of the bonding agent SBR onto the face thats receiving tile as with blue star this is not required although its recommended to be used on the sides and back. My advice would be to contact the technical helpline, on 0845 600 1 222
