Technical Manual – Section 8 Rapid Drying Lightweight

cement:sand screed and the lightweight aggregate may increase the indentation value obtained with the BRE screed tester. A ‘no-fines’ screed is made using a 1:4 mix by weight of Ardurapid 35 cement with 4/8mm Lytag (equivalent to 1:8 by volume) i.e. a 25kg bag of Ardurapid 35 cement with 4 x 25kg bags of 4/8mm dry Lytag.
