In the construction of epoxy floor, the bottom coating should be made of good quality materials: let part of epoxy penetrate into the base or waterproof layer and form a whole up and down. Enhance the bonding force, leaving less residual chemicals or gases after curing. After the epoxy construction, avoid sunshine and reduce the changes between the surface and the inner layer of the epoxy layer. In the construction of the base or waterproof layer, it is necessary to clean the residual ash layer and other debris. No gap shall be left between the waterproof layer and the base after construction. Users who know some common knowledge of epoxy floor paint know that the moisture content of concrete used in epoxy floor paint construction is generally less than 8%. Excessive moisture content will seriously affect the construction quality of epoxy floor, which will lead to poor adhesion of coating film, surface bubbling, delamination and other undesirable phenomena. As mentioned above, some water vapor, epoxy residues and gases in the base layer are wrapped in the epoxy and base layer to form bubbles of different sizes. Because the epoxy layer itself is impervious to water vapor, water vapor can not be eliminated, leaving behind the symptoms of bubbles.
1. Make waterproofing layer: For concrete foundation with high water content and rising trend of water content, professional waterproofing layer is needed to prevent late seepage from leading to floor failure.
2. Maintain ventilation in construction site: keep ventilation in construction site. Circulating air flow can accelerate the volatilization of moisture in concrete base surface, which is conducive to improving the bonding force between epoxy floor paint and base.
3. The evaporation of water can be accelerated by increasing the temperature of concrete base surface by heating (roasting). Floor customization is recommended to use air heating or radiation heating, not fire heating, because fire heating will increase the temperature of the air fog, so that water vapor in concrete condensation.
4. Humidity permeability system: The moisture permeability system has a very high water permeability, which can ensure that water vapor on the base surface escapes through the coating and avoid the foaming and falling off of the coating. It is suitable for the base surface which can not be installed with waterproof layer.
In order to prevent foaming of epoxy layer, three things should be eliminated in the construction of epoxy floor: water, sun exposure and ash layer. The company believes that the following measures should be taken to prevent the formation of bubbles in the bottom of the grass-roots waterproof layer, to prevent water vapor seepage upward, strictly control the moisture content of the grass-roots or waterproof layer within 8%, compressive strength greater than 20 mpa, and then carry out sanitation construction. Improve the bonding force between epoxy layer and base or waterproof layer, overcome the swelling force at the beginning of bubbles and avoid the occurrence of bubbles.
Seepage and impermeability, compressive resistance, strength greater than 20 MPA, and the ground has a strong bonding, and easy to bond with epoxy resin to form a super-strong whole. In addition, the waterproof layer shall not be subjected to heavy pressure within 3 days after completion of construction. How to deal with the moisture on the epoxy floor?
