BS 8204 Part 6 Synthetic Resin Flooring Type Categorisation

FeRFA No Type Description Duty Typical Thickness
1 Floor Seal Applied in 2 or more coats. Generally solvent or water borne LD > 150μm
2 Floor Coating Applied in 2 or more coats. Generally solvent free LD / MD 150 - 300μm
3 High build floor coating Applied in 2 or more coats. Generally solvent free. MD 300 - 1000μm
4 Multi-layer flooring Aggregate dressed systems based on multiple layers of floor coatings or flow-applied flooring, often described as sandwich systems MD / HD > 2mm
5 Flow-applied flooring Often referred to as ‘self-smoothing’ or ‘self-levelling’ flooring and having a smooth surface MD / HD 2 - 3mm
6 Resin screed flooring Trowel-finished, heavily filled systems, generally incorporating a surface seal coat to minimise porosity MD / HD > 4mm
7 Heavy duty flowable flooring Having a smooth surface HD / VHD 4 - 6mm
8 Heavy duty resin flooring Trowel-finished, aggregate filled systems effectively impervious throughout their thickness. VHD > 6mm

LD – light foot traffic, occasional rubber tyre vehicles, MD – regular foot traffic, frequent fork lift truck traffic, occasional hard plastic-wheeled trolleys, HD – constant fork lift truck traffic, hard plastic wheeled trolleys, some impact, VHD – severe heavily loaded traffic and impact


Substrates in contact with the ground must incorporate a functional damp proof membrane in accordance with CP102 or, in the case of basement floors, BS 8102. The base should have a relative humidity at the surface of no more than 75% when measured according to BS 8203. See data sheet for full preparation guidance.

Substrates must be clean, dry and free of surface laitance and contaminants such as dirt, oil, grease, poorly bonded coatings and surface treatments. Inadequate preparation will lead to loss of adhesion and failure. In coatings, there is a tendency for the finish to mirror imperfections in the substrate. Grinding, or light vacuum-contained shot-blasting, is therefore preferred over planing for these systems.

Mixed material must be used immediately. (minimum 15°C). Apply with a medium pile simulated sheepskin roller, working well into the surface, taking care not to exceed the coverage rate. Edges and difficult to reach areas may be applied thinly by brush. An anti-slip finish may be achieved by broadcasting the first coat to saturation, with kiln dried silica sand at 3 - 4 kg/m2. Allow the first coat to cure for 24 hours at 15°C (or longer in colder temperatures) then remove all excess sand with a stiff broom and vacuum. Apply a second coat to encapsulate the grains.
