• 91.060.30 Ceilings. Floors. Stairs

This part of BS 8204 gives recommendations for the design and installation of trowel finished polymer modified cementitious levelling screeds and wearing screeds, where the proportion of polymer solids based on the mass of dry cement is at least 4 %, as bonded screeds applied to direct finished concrete slabs, fine concrete screeds and to existing concrete floors within buildings.

This British Standard does not apply to unbonded screeds, floating screeds, pumpable self-smoothing screeds, or those laid monolithically, neither does it apply to two-component aqueous thermosetting polymer dispersions.
