hi there.
is there a reference guide or website etc that shows the amount of adhesive and grout needed for an certain area of tile.
i know you learn it instingtivly with experience.
i might only be doing a hand full of tile in one go so not mixing too much is important.
there are a lot of variable i know but a rough guide would be nice

thanks alan

Packaging on the bags will give you a rough guide .

unless your using bal grout, there specs seem to be way out...lol

i used a small bag of addhesive lately.
it said it would do 3m2 but struggled with 1m2

it depends on size of grout line , depth of adhesive, thickness of tile and size of tile, a small tile obviously has more grout lines. its always best to buy extra or a bigger bag to make sure you don't run out

im not too woried about the grout as its easy to mix another wee bit but addy is a neusence to have to mix more of. PITA when your short just enough for the last tile or two.

As a rough guide, a 20 kg bag of adhesive will do 4/5 m2 for floors using a 10mm round notch trowel and back skimming the tiles or 7/8 m2 on walls using a 6mm square notched trowel. As for grout, it's different every time depending on tile thickness, joint width and tile size, as Andy has already said, whatever BAL claim on the back of their bags, half it!
