Dosage:400mlRetanol®Xtremepermixtureinstandardscreedpump(mixingvesselwith250lgrosscapacity)
Important note: cement quantities below 62.5 kg and/or dosages below 400 ml do not bring about a greater increase in
strength than with screeds without Xtreme.
Fill the floor screed conveyor to about one-half with sand and the entire amount of cement as usual, add Retanol® Xtreme to
thefirstmixingwater(usually5–10litres)andthenfilltheconveyorcompletely.Insodoing,graduallyaddtherequiredamount
