Pointless IMO.I was just planning on using the leftover tanker for around the kitchen sink. HONEST!
If you look on the BAL web site it gives approximate coverage for all their products;How much should I buy of each, please?

A 20kg bag will cover approx 8sq/m of wet wall or 10sq/m of dry wall. So is thats a 6ft x 6ft room x 7ft high? If so & assuming you have wet walls, you will need 1 x 20kg bag & 1 x 10kg bag.Bathroom is 6 feet x 6 feet x 7 feet?
A 5 litre tub mix will do around 3.3 sq/m on a dry wall application which unfortunately sort of puts you in the middle; a 2 ½ litre tub will give you another 1.6sq/m. Ether that or but a 10 litre tub but you will then have some left over.Kitchen tiles being used are 3/4 square meters.
