Weber PR360 preparing anhydrite ,right or wrong

[chequers]

Hi all
Ok went for weber plus adhesive with Ad250
I have prepared the floors and started with the primer Weber Pr360. I understood that one 5 kg container would do approx 25 sq m at 0.2kg per sq metre however i am still on my first container having done over 100 sq m. It says for Anhydrate to water 3 or 4 parts to one part PR360 ,seems a lot of water to go into the floor.Any thoughts on this have you used it before ,going to have loads left ?

Thanks

You can only go with Weber spec.... each manufacture has different products/procedures for Anhydrite prep.

If you have done 125m2 and still got leftovers then you aint used enough.....
