Hi everyone, hope you are all well.
Two questions:
I want to tile over electric underfloor heating cables / Ditra Heat with 600x600mm large format tiles (9.5mm depth tile). My question is the adhesive that I have got which is the correct one for underfloor heating is 8 months old but on the manufacturers site it says ok to use up to 12 months old from date on bag but I'm a bit scared of using just in case it won't set properly. The adhesive has been stored in the house so at right temperature etc. Do you think I would be ok to use this as I have 15 x bags and really don't want to throw them out but at the same time don't want the job not right. Reason for age is because my mum and dad passed away recently so everything came to a stand still but now I want to get back to work and finish the job off.
Also I did some tests a few months ago to see what coverage I was getting and found I could get 90% coverage if I used a 20mm U notched trowel on floor and on back of tile which I know is a lot of adhesive but anything less did not give me the coverage required. I also use a 12mm square notched with 6mm on back of tile but it only gave me about 75% coverage. So would the 20mm U notch on both back of trowel and floor be ok. The adhesive can go to 22mm depth.
Many thanks in advance.
Gary.
