BS 8204-3:2004 + Amendment 2:2011 Screeds, bases and in situ floorings. Polymer modified cementitious levelling screeds and wearing screeds. Code of practice

BS 8204-3 gives recommendations for the design and installation of trowel finished polymer modified cementitious levelling screeds and wearing screeds. It applies 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.

BS 8204-3 does not apply to unbonded screeds, floating screeds, pumpable self-smoothing screeds, or those laid monolithically. It also does not apply to two-component aqueous thermosetting polymer dispersions.

This standard has been amended to include updates made to other cement and aggregate standards.
