Is this classed as slurry? And how many would we need for 24metres

logo

Our advice: No, this is specifically designed for use with Porcelain slabs. 1 x 12.5kg bag of Mortar Additive (6:1 mix) will cover approximately 2m2 at 25mm thickness so you would require x12 bags.

The ratio 6:1 is that one bag to 6 shovel off sand.. and how many slabs could you lay with this ratio (per bag)

logo

Our advice: The ratio would be 75kg sharp sand per 12.5kg bag. The coverage provided depends on how thick you plan to set the mortar.

How many bags to cover 16 square metres at 25 mm thick
