10、 ii BSI 28 November 2001 Foreword This part of BS 8204 has been prepared by Subcommittee B/544/6. It gives recommendations for floorings based on liquid synthetic resin binders, in which curing takes place by chemical reaction of the resin components, applied to a direct finished concrete slab, fine
11、 concrete screed, polymer modified cementitious screed or existing concrete floor and finished to the required level. The other parts of BS 8204 are the following: Part 1: Concrete bases and cement sand levelling screeds to receive floorings Code of practice; Part 2: Concrete wearing surfaces Code o
12、f practice; Part 3: Code of practice for polymer modified cementitious wearing surfaces; Part 4: Code of practice for terrazzo wearing surfaces; Part 5: Code of practice for mastic asphalt underlays and wearing surfaces. As a code of practice, this British Standard takes the form of guidance and rec
13、ommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for th
14、eir correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations Summary of pages This document comprises a front cover, an inside front cover, pages i to ii, pages 1 to 24, an inside back cover and a back cover.

16、the compound on which the first resin floorings were based. Many different types of resins are now used to manufacture resin floorings but the one common feature is that a polymerization, or curing, reaction takes place in situ to produce the final synthetic resin finish. Synthetic resin flooring is
17、 available in a wide range of thicknesses from thin floor seals to heavy-duty industrial protective coatings. The resulting flooring can provide a seamless surface with greatly enhanced performance compared with the concrete base on which it is applied. Concrete wearing surfaces give satisfactory se
18、rvice under many industrial conditions but become less effective where there are specific requirements for chemical resistance, hygiene, cleanliness, and resistance to high impact or abrasion. The main properties of synthetic resin floorings can be summarized as follows: a) a strong permanent bond t
19、o the concrete base; b) resistance to a wide spectrum of aggressive chemicals; c) impermeability to liquids; d) toughness, durability, resilience and resistance to impact or abrasion; e) hygienic and easily cleaned surfaces; f) resistance to cracking; g) low applied thickness; h) rapid installation
20、and curing with minimum disruption to normal operations. 1 Scope This part of BS 8204 gives recommendations for the design and installation of in situ synthetic resin flooring used internally in buildings, where they are bonded to direct finished concrete slabs, fine concrete screeds and to existing
21、 concrete floors. The installation of resilient sports surfacings based on synthetic resins is not covered by this code of practice. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this British Standard.

29、 support for a screed or flooring 3.2 flooring uppermost fixed layer of a floor that is designed to provide a wearing surface 3.3 direct finished base slab base that is finished to receive directly the flooring to be applied without the need for a levelling screed 3.4 levelling screed screed finishe
30、d to obtain a defined level and to receive the final flooring 3.5 synthetic resin reactive organic polymeric binder for a flooring system comprising one or more components which react in situ at ambient temperature 3.6 departure from datum deviation in height of the surface of a flooring layer from
31、a fixed datum plane 3.7 surface regularity deviation in height of the surface of a flooring layer over short distances in a local area NOTEThis is sometimes referred to as flatness. 4 Exchange of information and time schedule 4.1 General Consultation and exchange of information between all parties c
32、oncerned with the building operations should be arranged, so that each party has full knowledge of the particulars of the flooring work and is able to cooperate in producing the necessary conditions to complete a satisfactory job. Some of the items listed in 4.3, 4.4 and 4.5 may need special precaut
33、ions or procedures and responsibility for these should be determined in advance of the work. 4.2 Selection of flooring to be applied It is essential that, in the design and construction stages, there should be full consultation with the manufacturer of the synthetic resin flooring to ensure that the
