/ FeRFA: Resin Flooring Association: Product Types

Synthetic resin floorings can be divided into different types varying in thickness and surface finish:

Type Name Description Duty Typical Thickness
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 – 300 µm
3 High build floor coating Applied in two or more coats. Generally solvent free. MD 300 µm – 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 > 2mm
5 Flow applied flooring Often referred to as ‘self-smoothing’ or ‘self-levelling’ flooring and having a smooth surface. MD/HD 2mm – 3mm
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 4mm – 6mm
8 Heavy duty Resin flooring Trowel-finished, aggregate filled systems effectively impervious throughout their thickness. VHD > 6mm
Duty Key
LD [Light Duty] Light foot traffic, occasional rubber tyred vehicles
MD [Medium Duty] Regular foot traffic, frequent fork lift truck traffic, occasional hard plastic-wheeled trolleys
HD [Heavy Duty] Constant fork lift truck traffic, hard plastic wheeled trolleys, some impact
VHD [Very Heavy Duty] Severe heavily loaded traffic and impact
In general terms these categories of flooring are listed in ascending order of durability. However the actual life in a particular installation will depend on the product formulation used, the quality of the substrate and the degree of severity of the service conditions. Please refer to FeRFA’s ‘Guide to the Selection of Synthetic Resin Floors’ (ISBN 0 9538020 3 5) for further information on the features and characteristics of the floor types. Some of these categories 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 5 and 8. Slip resistant or anti-static/conductive versions of all these categories may also be available.
