2K Epoxy Dust Sealer Matt Finish

Substrate Preparation

Prepare the substrate by either light vacuum shot blasting / or grinding and remove rough contamination by grinding (as required). The surface must exhibit a minimum compressive strength of minimum 25 N/mm² and adhesive strength of minimum 1.5 N/mm². The surface must be clean and free of dust and loose particles. All traces of contaminants, including oils, fats, grease, paint, chemical and laitance should be removed. Any cracks or damage should be properly remedied prior to application.

Application Instructions

Prior to application, the material should be heated to an ambient temperature (air and floor temperature).

The A component should be stirred for 1–2 minutes before added entire contents of B component and mixing for further 2–3 minutes. Use a slow speed drill and helical spinner, taking care not to entrain air. Subsequently the mix can be diluted with unto 10% water (maximum) into the first coat only. The material should be sieved by pouring into another container (either with a paint filter with 0.6–1.0mm mesh size, or with a household sieve with inlaid fly screen or similar fabric, mesh size <1mm). We recommend the application by equal batch numbers. The product is poured immediately onto the prepared surface and applied with a roller or rubber squeegee. A seconded coat is normally recommended. Pooling should always be avoided as this will lead to variations in the visual appearance of the cured material. In order to ensure a fast evaporation of the water, the relative air humidity should not exceed 85% during processing and curing. Air circulation is recommended however drafts should be avoided. Direct sunlight, high temperatures and low humidity cause rapid curing and should be avoided as otherwise it may lead to skin formation, approaches or visible rake marks. We recommend the application by equal batch numbers and it is also important to keep a wet edge between two pours of material as they will otherwise be visible.
