BS 8204-7:2003

Screeds, bases and in-situ floorings. Pumpable self-smoothing screeds. Code of practice | Status: Confirmed, Current

1 Scope This part of BS 8204 gives recommendations for materials, design, work on site, inspection and testing of pumpable self-smoothing screeds (often known as “self-levelling screeds”).

NOTE There are two principal types of pumpable self-smoothing screeds, one predominately based on cementitious binders and the other predominately based on calcium sulfate binders.

The recommendations cover the use of pumpable levelling screeds and pumpable wearing screeds in buildings. As a levelling screed, the screed is intended to receive floor coverings such as:

1. a) textiles;
2. b) linoleum;
3. c) polyvinyl chloride;
4. d) rubber;
5. e) cork;

or rigid floorings such as:

1. f) wood block and strip;
2. g) ceramic tiles;
3. h) natural stone;
4. i) synthetic resin wearing surfaces.

As a wearing screed, the screed is intended to provide a wearing surface itself.
