Use of this document

As a code of practice, this standard takes the form of guidance and recommendations. 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.

Any user claiming compliance with this standard is expected to be able to justify any course of action that deviates from its recommendations.

The provisions in this standard are presented in roman (i.e. upright) type. Its recommendations are expressed in sentences in which the principal auxiliary verb is “should”.

Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.

Contractual and legal considerations

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard cannot confer immunity from legal obligations.

Introduction

The term “resin” is derived from “epoxy resin”, the compound on which the first resin floorings were based. Many different types of synthetic 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 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 service 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 strong permanent bond to the concrete base;
resistance to a wide spectrum of aggressive chemicals;
impermeability to liquids;
toughness, durability, resilience and resistance to impact or abrasion;
hygienic and easily cleaned surfaces;
resistance to cracking;
relatively thin applied thickness;
rapid installation 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, based on liquid synthetic resin binders in which curing takes place by chemical reaction of the resin components, used internally in buildings. The synthetic resin floorings are bonded to direct finished concrete slabs, polymer-modified cementitious or fine concrete screeds and to existing concrete floors.

Annex A gives recommendations for the design and installation of resin terrazzo flooring.

Synthetic resin floorings applied to other materials such as timber or metal are not covered by this code of practice.

The installation of resilient sports surfacings based on synthetic resins is not covered by this code of practice.
