[Diamond Pool Finishers]

you are jumping to to many conclutions dim , dot and dab, screed breaking up, wot next!!!!

 

[murf]

steady on gooner. Are you sure you'r not a millwall fan?

Gooner, sit down, have a rest and chill out. Firstly no one is jumping to any conclusions, that would be the case if I had simply stated one problem and one method to resolve it, however as I asked Adrian to check out the theories I was offering I believe that would come under narrowing the problem down. Hollow tiles are usually the result of dot and dab fixing, no enough coverage with a trowel or a suspect screed. I have as you have asked me to do re-read your reply and Yes you do actually say the words "but PVA is ok m8".
In regard to your point about coffee, I dont drink the stuff and fail to see its relevance, I have never starred in any programmes with Kermit or Miss piggy so how coulod I be a muppet? I have never met Jim henson and I believe he is actually dead.
I do hope this clears things up for you and allows you to calm down.

hi adrian 2009 couple of questions how long did the builder leave (render)cement to dry befor tiling . is there a perimater expansion joint and just how soft is the render (can you dig a hole using keys :8:

 

[Adrian2009]

I dont remember how long was left for concrete to dry out, but am guessing around 2 weeks with conservatory roof on for at least a week.

Also, not sure but dont think screed was added, concrete was left with even enough surface.

Concrete is very hard and even with small 1/2" chisel it takes a heavy blow to break surface.

hi tiles may have been put down to early on concrete needs time to cure (dry out) has a expansion joint been left between tiles and exterior walls :8:

 

[Adrian2009]

yes there is a joint between tiles and wall, filled with grout

 

[diamondtiling]

thats not an expansion joint mate, it should be a manufactured expansion joint, it allows for movement and helps to eliminate cracks etc

 

[jay]

hi that joint should be filled with silicone that why your edge tiles are lifting off .the floor tiles need to move (expand) if they cant move sideways they move up or lift could also be not letting slab cure lack of primer but sounds like lack of expansion :8:hope that helps
