base coat should do about 1.5 m a bag, the top coat should do 4 m2 a bag and the chippings will cover 3m2 a bag.
You have to mix topcoat with chippings aswell so you will allow extra topcoat. usually 3 chippings to 1 bag of topcoat.
Mix the whole lot (35m2) of roughcast up in a big bath or something to ensure the colour is equal throughout your elevation.
