Mixing latex with rapidset adhesive

[postie]

Hi all
Going to lay a slate fireplace soon but when i read the label on the liquid latex it states that you have to mix the whole bottle with 4 kg of adhesive but i don't need anywhere near this much,but guessing on what quantities to put in is also dodgy or do you mix the lot regardless.

usually you mix it on a 50/50 basis,but depends on the make..i use bal AD1 and this is a 50/50 mix.......if in dowt ring the tecq line number on the bottle.........dave..
