I am very relaxed and I am sorry you think I am being anal I am just asking you to clarify a few points in your general statement. when I was reading it it came across as a load of nonsense. When you are talking about limited bed depth for ready mixed adhesives and there are the same sort of limitations fore most cement based adhesive. Then you go on to say “ If I was to hazard a guess at bond strength comparison then I'd say a fully set dispersion adhesive would be greater but that's just my guess.” so are you talking about ready mixed or cement based ?? The other thing that I am confused about is “however I have seen what one of these jobs looks like after a few years... Not so good, tiles have been sucked back on to the profile of original substrate instead of the initial flat plane as how they where initially installed.” are you saying that the ready mixed adhesive sucked the tiles back that far over a period of years??
I have over the last 20 odd years fixed tiles of the correct size with ready mixed adhesive and I have had to bed out using it and I have never in all that time come across an instance where the tiles have sucked back that far that they followed the original profile of the wall.
Thought I was being clear, I'd say a fully dried ready mixed bed would have a higher bond strength than a fully dried cement based.... Just a guess mind!!
yeah, that's what I'm saying, tiler used tubbed adhesive putting one big dollop at each end of the ceramic tile, the tiles where split with an aluminium horizontal pencil border, I had a look at the job and remember being very impressed at how flat they where, really was quite a tidy finish. Over the next few years it was very apparent that something was happening to the tiles, they where not flat anymore and this was made very noticeable against the straight border, when you looked down from a more acute angle you could see they where not flat anymore. The job looked very DIY after 1+ yrs .... What's your expert reason for this Delano? Could it be that the big dollops of adhesive had shrunk over time?
