Precautions for Epoxy Floor Coating Construction
In practical construction, epoxy floor paint can adjust the fineness of sand based on the thickness of the mortar layer. The mortar layer can be shaped multiple times or formed in one go. Primer formula for floor coating: for dry surfaces; resin components: epoxy resin, xylene, n-butanol. Hardener: polyamide, xylene, n-butanol. For wet surfaces; hardener components: alicyclic amine, ratio, resin components, hardener components. Some manufacturers directly use polyurethane prepolymer diluted with solvent as a moisture-curing sealing primer for epoxy floor paint, which is used on dry substrates, yielding excellent results. Epoxy floor paint not only seals the substrate but also enhances the adhesion between the substrate and the coating. The intermediate coat can level the substrate and perform further processing; on the other hand, epoxy floor paint can increase the film thickness, improve load-bearing capacity, corrosion resistance, and extend the service life of the coating. In the construction of epoxy factory floor paint, it is generally insufficient to only apply the topcoat; a primer and intermediate coat are also required. When epoxy is shaped multiple times, the fineness of the sand usually decreases gradually from bottom to top. The mortar layer has good mechanical properties; for solvent-free or low-solvent mortar layers, the compressive strength can reach 80 MPa, far exceeding that of ordinary concrete.
