The 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 load to which it will be subjected after system installation.
The substrate must be structurally sound. Loose or unsound concrete should be removed & made good. Surfaces must be entirely free of oil, grease, paint, corrosion deposits, dust, laitance, curing compound residues, or other surface deposits. Repair to the substrates, filling of blowholes/ voids and surface leveling must be done before coating application.
The preferred method for surface preparation of concrete is captive blasting. This produces a well-prepared laitance-free, the vacuum-cleaned surface to produce a lightly exposed aggregate surface. Alternatively, the use of light mechanical scabbling, grit/shot-blasting, or grinding with a diamond disk, followed by vacuum cleaning can also be utilized. Surface irregularities must be ground down or filled out with RepairPro EP FC/ RepairPro EP FCB or repair materials from RepairPro range.
Priming/ Sealing/ Basecoat:
FloorPro PU-ED requires priming. Based on the project requirements, the floor should be primed with FloorPro Primer SF. Apply FloorPro Primer SF to the prepared surface at an application rate in the range of 0.15 to 0.30 ltr/ m². Quantity will depend on surface texture and porosity. Whilst FloorPro Primer SF is still wet, blind with the required size of FloorPro Anti-Slip Aggregates at an estimated rate of between 0.6-1.0 kg/m², leave to dry for 16 hours @ 35º C. Prior to the removal of excess FloorPro Anti-Slip, Aggregates ensure that the grains are firmly embedded in the primer. Apply FloorPro EC 200 or FloorPro PU-ID as a basecoat to the primed surface broadcasted with FloorPro Anti-Slip Aggregates at an application rate in the range of 0.2 to 0.5 litre/m², per coat depending on the size of FloorPro Anti-Slip Aggregates
