• Over underfloor-heating systems installed to the heating-system manufacturer's instructions and project design

For professional use only. FORCEM screed is not a standalone waterproofing membrane or final wearing surface. Apply only when ambient and substrate temperatures are between 5C and 30C. Maintain the 5:1 sand/aggregate-to-binder ratio by weight. Do not add Portland cement, lime, gypsum, other binders or unapproved admixtures. Do not exceed the required total water content, retemper the mix or use material after its working time. Do not use fine sand alone or contaminated, saline, clay-bearing or excessively fine aggregate. Do not bridge active cracks, structural joints or movement joints. Minimum thickness: bonded 10 mm, unbonded 40 mm, floating 55 mm. Do not install floor coverings until curing and residual-moisture requirements are achieved, measured with an approved calcium carbide (CM) test. Protect from rain, frost, strong wind, direct heat, rapid drying and premature traffic. Use ACTFLEX 300 only where specified and do not add it to the full standard water quantity.
