Interesting post guys. I know that most adhesive manufacturers encourage mixing of different products to different tasks e.g.
- Using thick bed self level compound in one floor area , and
standard (cheap) set in another.
- Using standard setting floor adhesive in kitchen to save costs, but extra fast rapid set for washing machine or fridge floor area.
If you should not mix their products they normally state that on packaging. However no one recommends different manufacturers products used for tiling same area.
Also note comment from Stewart about different attitudes of different tilers to laying floor tiles. Two considerations here - do what you have to to make a good installation, then do what you can to do it as quickly as possible. Now that does depend on the size and type of room. If tiling a small bathroom, including cuts around toilet and sink pedestal I always dry cut first - I was taught that you lay the whole tiles first, then you know you can get the cuts spot on. For larger rooms I tend to lay all the whole tiles from centre to edges in quadrants. Then cut edge tiles and lay all in one go. I find that more accurate and quicker for me - again taking the way I was taught - making cuts from surrounding whole tiles.
