SELF-SMOOTHING FLOOR SCREEDS, FLOW-APPLIED AND FLOWABLE RESIN FLOORING
Although the term 'Self-Leveling Floor Screed' is most frequently used to describe flowable resin floor screeds, it is not strictly true; so 'self-smoothing', 'flowable' or 'flow-applied' are more accurate descriptions. The term self-levelling suggests that it is possible to pour the resin screed on to an unlevel surface and it will hide all of the imperfections to give a perfectly level floor. However, surface potholes, undulations and out-of-level floors should be repaired/addressed prior to applying a flowable screed, because it will simply follow the profile of the floor, smoothing itself over the profile of the undulations.
The Resin Flooring Association categorises two types of flowable resin flooring:
Resuthane SL is a three-part polyurethane flow-applied resin floor screed that comes in two grades. SL 23 is laid at 3mm and SL 45 is laid at 5mm.
Pumadur SL is also a three-part polyurethane flow-applied resin floor screed that is laid at 2-3mm. It has high chemical and abrasion resistance suitable for medium duty applications.
Pumaflow is a three-part flow-applied epoxy resin floor screed laid at 2-3mm with a smooth gloss finish. It suits medium duty applications, has good chemical and excellent abrasion and wear resistance.
Resuflor DM is a three-part flow-applied epoxy resin floor screed laid at 2-3mm to provide a smooth gloss finish. It provides a robust chemically resistant surface that is also decorative.
Resuflor Crystal Bright (CB) an epoxy self-smoothing screed giving the same high quality technical performance as Resuflor DM, but also offering a superior stunning colour palette offering intensity and vibrancy sought by designers, with a smooth gloss finish. Laid at a minimum of 3mm.
Resuthane Crystal Bright Self Levelling (CBSL) a polyurethane self-smoothing flow-applied flooring screed laid at 3mm. The Crystal Bright colour range offer a superior choice of vibrant intense colours, and the resuthane system gives a smooth matt surface finish.
Resustat SL23 is a four-part polyurethane electrostatic dissipative self-smoothing flooring. It is designed for areas that require anti-static, hard-wearing and chemically resistant floor surface - such as pharmaceutical production, electronics manufacturing, explosives factories, operating theatres, food processing, tv studios and chemical plants. It is laid at 3mm thick and provides a seamless, smooth matt finish. Resustat SL23 meets the performance requirements of BS 2050 for industrial floors. The Resustat SL23 Anti-static Flooring System has an electrical conductivity leakage resistance of 5 x 104 to 108 ohms when tested to BS2050/1978.
