The new BS 8204-6 (following the FeRFA Guide) states in section 4.2 that: “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 product to be selected is entirely suited for the conditions both during application and in subsequent service”.
Consideration should therefore be given to whichever of the following are applicable:
- intended use of the synthetic resin flooring including the type, extent and frequency of trafficking;
this can be categorised, as follows
Light duty (LD) – light foot traffic, occasional rubber tyred vehicles
Medium duty (MD) – regular foot traffic, frequent fork lift truck traffic, occasional hardplastic-wheeled trolleys
Heavy duty (HD) – constant fork lift truck traffic, hard plastic wheeled trolleys, some impact
Very heavy duty (VHD) – severe heavily loaded traffic and impact
- type of loading, static or dynamic, and severity of impact;
- details of all chemicals, including those used for cleaning or sterilising, which could come into contact with the floor, and extent, frequency and temperature of spillage;
- temperatures that the flooring is required to withstand in normal service or as part of the cleaning operations and whether exposure is by radiant or conductive heat or by direct contact;
- colour, uniformity and retention, aesthetics and decorative effects;
- extent to which the flooring will be exposed to direct sunlight or ultra-violet light;
- appearance and quality of finish;
- need to reduce risk of osmosis;
- compliance with hygiene or food industry requirements;
- special requirements, such as slip resistance or static controlled characteristics;
- expected life of the flooring;
- thickness of flooring to be installed;
- time available for the application and curing of the flooring;
- age, specification where known and nature of the base, including information about any previous use of the floor which could affect adhesion, and any preparatory treatment required.
Types Of Synthetic Resin Flooring
Synthetic resin flooring is classified into eight specific types, each exhibiting its own particular performance characteristics. A variety of synthetic resins, typically epoxy, polyurethane and methacrylate, can be formulated to produce the different resin types. BS 8204-6, Section 6.2 (following the FERFA scheme) classifies the types, varying in thickness and surface finish, as follows:
|1||Floor Seal||Applied in two or more coats.
Generally solvent or water borne.
|LD||up to 150 µm|
|2||Floor Coating||Applied in two or more coats.
Generally solvent free.
|LD / MD||150 µm to 300 µm|
|3||High Build Floor Coating||Applied in two or more coats.
Generally solvent free.
|MD||300 µm to 1000 µm|
|4||Multi-layer Flooring||Aggregate dressed systems based on multiple layers of floor coatings or flowapplied floorings, often described as ‘sandwich’ systems.||MD / HD||> 2 mm|
|5||Flow Applied Flooring||Often referred to as ‘self-smoothing’ or ‘self-levelling’ flooring and having a smooth surface.||MD / HD||2 mm to 3 mm|
|6||Resin Screed Flooring||Trowel-finished, heavily filled systems, generally incorporating a surface seal coat to minimize porosity.||MD / HD||> 4 mm|
|7||Heavy Duty Flowable Flooring||Having a smooth surface||HD / VHD||4 mm to 6 mm|
|8||Heavy Duty Resin Flooring||Trowel-finished, aggregate filled systems effectively impervious throughout their thickness.||VHD||> 6 mm|
Some of these types of flooring may be produced with special decorative effects by the incorporation of coloured particles or flakes in the surface. Terrazzo-like finishes (ground exposed aggregate) may be produced from certain trowel-applied floorings of Types 6 and 8. Slip resistant or anti-static/conductive versions of all these categories may also be available.
The following tables have been produced to explain the relationship between the properties available within a particular flooring type and the conditions under which that flooring type will be applied and used in service.
