Many users think that the construction of epoxy floor, that is, land cleaning and finishing, and then directly roll on the top coated with epoxy floor paint on the line? Actually not! Epoxy floor paint construction, not just land painting! In essence, the construction of the right way floor paint and "floor painting" is very different, more and more is the base management and implementation. Workmanship.
Requirements for concrete land: concrete is required to be flat and compact, strength requirements are not less than C20; land flatness is usually required to drop within the 2M boundary less than 2 mm; if the drop is large, the floor coating should be thickened to reduce the drop.
If the land to be coated is in the basement and other areas, the groundwater level is high, the concrete floor should be waterproof; the newly poured concrete dried up for at least three weeks, the moisture content is not higher than 8%.
Base surface is the basic quality of all the terrace items, not reaching the above criteria of land, need to implement the following procedures: processing objectives: to increase the flatness of land seats, remove floating layer and dirt, to obtain a uniform rough surface for coating adhesion.
Requirements: Arrive on the land solid, no sand holes, holes, and at the same time dry, clean, no dust, oil, cement sand and other debris. Procedure: Choose land grinding machine seat grinding - dust absorption - repair large holes, dents and cracks. Old paint layer (1 mm thickness below the old paint layer can be used diamond cutter), because of the high cost of handling, if customers do not require seating to remove old paint, only remove loose old coating, remove surface oil and debris.
