Before the construction of epoxy flooring, which base surface should be done well for employment before the construction of epoxy flooring, which is the condition for guaranteeing the construction quality of the flooring, and also one of the key control points of construction. What is the employment of the base surface? (1) The surface roughness necessary for the demand of the base surface, raising the adhesion coatings adhere to the floor, depending on. The use of polar groups in coatings and verbal branches of floors for interacting with machines is emphasized. After grinding and sandblasting, the verbal area will become rough and the verbal area will increase markedly, which will increase the confrontation area between coatings and floors and the use of machine interacting, and increase the adhesion of coatings.
(2) The matching between the new coating and the bottom layer in the maintenance project, touching the abnormal treatment of the old coating, it is still the department's maintenance to make clear whether the overall situation of the new coating can go out together or not. If it is protective coating, when the new and old coating matching is appropriate, it is advisable to consider maintaining the invalid old coating, so as to further strengthen the overall protection talent of the coating; If the decorative properties are the main objective of the painting project, the old coatings should be removed altogether. Or after polishing the old coatings, scrape and smooth the putty to ensure the flatness of the substrate.
(3) Do a good job in the clean employment of the lower floor, in view of the poor compatibility between oil and water and paint, if there is oil stain and water in the floor orally, it is difficult to construct a continuous coating, even if it becomes a perfect coating, it will greatly reduce the adhesion and make the coating too early and lonely; when there is dust and gravel in the floor orally, it will make the coating pitting and make it urgent to change。 Appearance: When the floor is verbally uneven, with pits, voids, cracks and so on, it will affect the appearance quality of the coating, and it can not be painted at all when the situation is urgent。 Therefore, before painting, the floor should remove the dirt from the base surface, strengthen the adhesion of the coating to the ground, extend the service life of the coating, and fully extend the decorations and safeguards of the coating。 Flat construction also means the same。 Only in every clean, flat and empty mouth can the construction quality of the floor be guaranteed。 The painted floor is smooth, flat, elegant and has excellent ornamental functions。
