Where To BuyThe long-term durability of any resin floor system is determined by the adhesive bond achieved between the flooring material and the substrate. It is most important therefore that substrates are correctly prepared prior to application. These should normally have been placed for at least 28 days and have a moisture content of less than 5%. The compressive strength of the substrate concrete must be at least 25 N/mm² and its tensile strength must be at least 1.5 N/mm². The strength of the substrate must also be suitable for its final use and the types of loads to which it will be subjected.
The substrate must be structurally sound. Loose or unsound concrete should be removed and made good. Surfaces must be entirely free of oil, grease, paint, corrosion deposits, dust, laitance, curing compound residues or other surface deposits. The preferred method for surface preparation of concrete is captive blasting. This produces a well-prepared laitance free, vacuum cleaned surface to produce a lightly exposed aggregate surface
