Comfort Flooring – Part One
‘Comfort flooring’ or ‘liquid vinyl’ resin systems have been growing in popularity in recent years. These types of resin floors are generally a modified FeRFA Type 5 flow applied system, comprising a primer, a flow applied ‘body coat’, optional surface sealer and may include a rubber underlay and associated adhesive and pore filler. This type of resin flooring aims to offer the user the comfort properties typically provided by cushion vinyl, with the additional benefit of providing a seamless hygienic floor. Comfort flooring is monolithically bonded to the substrate and therefore removes the need for welded joints. Resin flooring can also be overlaid at the end of its life span unlike vinyl which needs to be removed and disposed of.
These type of systems generally obtain their resilient properties from the ‘body coat’, which is usually a flexible 2 – 4 mm flow applied two-part resin self-smoothing material, and often may incorporate a filler component to increase the overall thickness of the system. Some ‘body coats’ are inherently colour stable and may be given a clear coat for scratch resistance or left un-coated. . The non-colour stable grades are usually specified with a thin colour stable top-coat. A slip resistant topcoat is also an option. Comfort Flooring systems may have a shorter lifespan than other Type 5 systems due to the relatively low thickness of the topcoat. Systems incorporating a underlay mat require an adhesive to bond the mat to the substrate and a pore filler to grout any holes between rubber crumb particles. The body coat may be specified in two thinner applications (for example 1.5 mm each) to improve smoothness and reduce the risk of protruding rubber particles affecting the surface finish.
