Epoxy floor paint is a more beautiful paint. In the middle and late of the last century, many clean workshop floors began to appear, known as "epoxy floor paint". This floor paint has the advantages of seamless, convenient maintenance, anti-corrosion, dust-proof and low maintenance cost. With anti-skid property, parking lot ground must have a certain degree of roughness, general cement ground is difficult to meet the requirements. Below we will "epoxy floor paint features and base treatment" to understand in detail. 【环氧地坪漆的基面处理】
[Base treatment of epoxy floor paint]
1. Cement mortar or concrete base must be firm, compact and flat. The gradient and strength of base should meet the requirements. There should be no sand, shell, crack, honeycomb linen and other phenomena. The strength of the base material must be greater than 2Mpa. The strength does not meet the requirements. After curing, the epoxy resin coating will open the base surface and cause peeling. For base cracks and honeycomb linen surface, epoxy mortar or epoxy putty should be used to fill and repair, and the paint can be applied only after fully drying.
2. The moisture content of concrete should be below 8%, otherwise it should be excluded before painting. There are several ways to remove moisture:
Ventilation: Enhance air circulation/accelerate air flow, take away moisture, and promote further volatilization of moisture in concrete.
Heating: Increase the temperature of concrete and air, accelerate the rate of moisture migration to the surface of concrete, and make it evaporate rapidly. Forced air heating or radiation heating should be adopted. Combustion products (including water) produced when heated directly by fire source will increase the temperature of air fog point, which will cause water to condense on concrete, so it is not suitable to use them.
Reducing dew point temperature in air: dehydrating dehumidifier, dehumidifier or introducing outdoor air (the dew point of introducing outdoor air is lower than the temperature of concrete surface and above) are used to remove water vapor in air.
3. The surface of the base must be clean, and the floating ash, cement slag and loose parts of the base surface should be cleaned up before the coating is applied. The treatment method of base surface should adopt grinding wheel or wire brush to polish the surface, and then clean it with clean soft brush, compressed air or vacuum cleaner. When conditions permit, light sandblasting can be used to form a uniform rough surface at the grass-roots level.
There is no rough surface in the base layer, which will affect the adhesion between the paint film and the base layer, but the base layer is too rough, which will cause a lot of waste of materials. Therefore, suitable roughness is very important to the quality of coatings. If there are oil impurities on the ground, it should be wiped clean with solvent.【环氧地坪漆的特点及相关介绍】
[Characteristics and related introduction of epoxy floor paint]
Because the tile floor is not easy to penetrate, its own surface is relatively flat and smooth, so many people are doubtful whether industrial floor paint can be laid on the tile floor. Now I will introduce the characteristics of epoxy resin floor to you, and solve your doubts.
Epoxy floor paint has many advantages, such as high strength, wear resistance, beautiful appearance, seamless, solid texture, good resistance, anti-corrosion, waterproof, dust-proof, convenient maintenance and low maintenance cost. It is not only used in clean workshops, sterile rooms, but also gradually occupies the market of floor decoration. Moreover, the epoxy floor paint is mostly carried out on the cement floor, and the ceramic tile floor is bound to increase the difficulty of construction because of the gap between them.
Now we make a brief analysis on how to construct epoxy floor paint on ceramic tile floor, in order to relieve a series of unnecessary worries about the service life, floor delamination and smoothness of ceramic tile floor construction.
1. Whether for cement floor or tile floor, we must grind, and for tile floor, we must grind deeply. Because the tile floor material itself is relatively dense, it is not easy to penetrate and bond. Only by grinding the ground roughly, can we enhance the bonding effect between floor paint and the ground, and relative to the ground. In order to get a high smoothness and wear-resistant ground, the gap between tiles must be solved. This is a relatively time-consuming but very important step.
2. Primer construction of epoxy floor paint. Because the epoxy floor primer plays a connecting role in the coating of the floor paint, the construction must be sufficient and uniform to enhance the strength and wear resistance of the epoxy floor primer, so as to avoid the occurrence of shelling, delamination and other phenomena.
3. The mortar layer of epoxy floor paint must be thickened.
4. In the construction of epoxy floor paint, roll coating, brushing and steamed bread coating can be used according to the actual needs of customers to achieve different results.
