Hello,materials needed for above tiles.I presume main bathroom and ensuite are upstairs on timber floor.Floor should be WBP screwed down every 10 inch's.For timber floor you need flexible adhesive.On the walls its best use poweder wall adhesive (NOT RAPID SET) rather than bucket adhesive.A lot better quality for a few euro more.Not all tile shops sell powder wall adhesive. Tubs and tiles will stock it.
1. Kitchen floor and downstairs bathroom floor - Two 20kg bags of rapid set adhesive. (one bag does 6 yards)
2. Bathroom and ensuite floor - Two 20kg bags of flexible rapid set adhesive.
3. Kitchen wall/above bath and shower wall - Three 20 kg bags of poweder wall adhesive.(one bag does 8 yards). Tubs and Tiles brand is Dunlop wall and floor adhesive in a blue bag.
4. 10 kg of white grout. (1 kg does 4 yards)
5. 10 kg of grey grout. ( 1 kg does 2 yards)
Follow these amounts and you wont go wrong.
