Base surface floor paint repair method

Abstract

The invention discloses a base surface floor paint refinishing method. The refinishing method comprises the following steps of: 1) cleaning a base surface requiring construction; 2) spray-coating the base surface with a cement hardener; 3) pouring self-leveling mortar on the base surface and leveling the self-leveling mortar; 4) after fully drying the self-leveling mortar, coating the self-leveling mortar with an epoxy primer paint; 5) after fully drying the epoxy primer paint, coating the epoxy primer paint with an epoxy top paint, thereby realizing the aim of refinishing. The refinishing method has the advantages of being simple in refinishing technology, easy to realize, high in construction efficiency, good in refinishing effect, less in possibility of shrink and crack, high in mechanical strength, resistant to abrasion, resistant to corrosion and the like, the refinished paint can stand crushing and rubbing from normal vehicles and the service life of at least five years can be guaranteed; the method is especially applicable for refinishing old garages, production workshops, warehouses, offices, laboratories, reference rooms, hospitals, basements and the like; and wide popularization and application are benefited.

Description

technical field [0001] The invention belongs to the technical field of base surface repair, and in particular relates to a base surface floor paint repair method. Background technique [0002] Floor paint has the advantages of strong penetration and excellent adhesion to cement, high hardness, good mechanical strength, wear resistance and corrosion resistance. It is mainly used for cement floors that need to be purified, such as production workshops, warehouses, offices, laboratories, reference rooms, hospitals, basements, etc. [0003] In some underground garages, after the floor paint has been put into use for a period of time, the floor paint will frequently fall off. In most cases, there is a certain relationship with the base surface treatment. [0004] According to the standard process, before the construction of floor paint, the requirements for the base surface are very high. The compressive strength of the base surface is greater than C25, the surface tensile stre...

Problems solved by technology

[0007] There are two traditional methods to deal with the pulverized base surface. One is to shovel off the pulverized layer until it reaches a solid base surface, which is labor-intensive, time-consuming, costly and inefficient, and will bring great inconvenience to the owner; It is to use a large amount of epoxy primer for repeated penetration, and the reinforcement effect is good, but a large amount of epoxy primer will produce a lot of unpleasant smell, and when using epoxy primer for reinforcement, the dryness of the base surface is required Extremely high, not conducive to improving construction efficiency
