Floor paint primer should be carefully as follows: according to the material to be coated with the appropriate primer, the general use of the provisions is that the floor coating needs to use white-dry paint, steel oral need to use anti-rust (anti-corrosion) primer, cement oral need to use alkali-resistant primer; Should strictly comply with the use of seating product technology precondition of the main agent. Mix with the curing agent, make the primer and mix well, if necessary, finish after ripening.
The drying time prescribed by the technique of the seating product used and the better painting barrier shall be followed to implement the construction of the next coating; the primer shall be released with the exclusive release agent, and the parameters of the release agent shall not exceed 5% of the total leading amount; the painting control points and procedures of the relative product expression book shall be strictly complied with; the primer shall be coated uniformly, completely, and not. There should be symbols such as leakage and stacking. The pretreatment of substrate should be strictly respected from the foregoing related premises.
Primer is a coating in the coating system in the middle or under the surface layer, or directly coated in the oral coating of the substrate. Primer must have good support for the substrate, and has good adhesion and mechanical strength, as between the oral coating and other coatings, can make a stable connection between the two. A stable covering layer.
Primers have strong anti-rust ability (for steel) and filler surface ability (for cement-based surface). Epoxy resin primers, polyurethane primers, ethylene resin primers, etc. are more commonly used in floor coating. The more commonly used application of floor primers is brushing and roller coating, brushing is especially suitable for edges and corners and other complex parts of the style. Construction. Roller coating is suitable for large area construction.
