The perils of ready mixed adhesive.

[hitbit]

Hi and thanks for the reply.
Will take your advice and avoid Unibond ready made adhesives. I did leave an expansion joint between the wood and concrete.
The floor area is 18 sq yards. approx 15 is concrete and 3 locked down 18mm marine ply which has been in place for approx 8 years. The area has never suffered from any dampness whatsoever. The area was very uneven as it was originally 3 small rooms with dividing walls which I have now removed. I have covered the whole area with a latex based leveller which has removed most of the unevenness but there are a couple of spots which would need more than 3mm of adhesive. The tiles I intend to use are ceramic 450mm x 450mm. I am here in Dublin Ireland and so do not have access to anything like the huge range of products available in the United Kingdom. B and Q here do stock some Unibond products so I would welcome your advise on their powered ones as Unibonds website is very poor offering little or no advice on their products or how to use them. There are suppliers of BAL products and again I would appreciate your advice regarding same.
I have successfully tiled walls in the past using much smaller tiles and ready mixed adhesives but would really like the experience/satisfaction of tiling this floor myself. I really appreciate your taking the time to help me with same.

Hi Martin, when you say there are a couple of spots that need more than 3 mil of adhesive, what trowel size do you have in mind?
Have you got a tile giant near by?

Hello Newbie here.

Perils of ready mixed very interesting indeed. I would appreciate any suggestions/help with the following. I intend to lay 450mm x 450mm ceramic floor tiles on a mixed surface of concrete and timber both of which have been covered with a layer of self levelling compound. I have been told tyhat I will still need to use a flexible adhesive over the timber. Is there a powder adhesive which can be used over both surfaces. Would Unibond Tile On Floors all purp[ose adhesive be suitable.

Thanks

If you mix a bag of standard set addy and use a 6mm trowel, it will go twice as far as a bucket addy and is therefore more cost effective.

I use a minimum of a 10mm trowel on walls (exept kitchen splashback with small tiles) - you cant do this with tubbed addy.

The best thing about tubbed addy is you get a grouting bucket after you have used the adhesive :lol:

Hi Diamondtiling,

There are a couple of spots which are approx 3mm. I was thinking mabey a 6mm trowel and using Bal PTB Flexible.
I would welcome your comments, and advice on the best manual method of mixing powder adhesives, ie powder into water or water over powder
