Scraping solvent-free epoxy intermediate coatings, in the case of film thickness requirements, it is necessary to adopt scraping solvent-free epoxy intermediate coatings to meet the requirements of film thickness, at the same time can make the ground flatness added, but also can enhance the mechanical strength of the entire floor. Select the scraping method, mix the component A, then pour the component B into the component A, and then mix it well for more than 3 minutes until the coating is even. After mixing, the operation period is 30 minutes (25 degrees Celsius). The moisture content of the coated material is more than 8%, the surface temperature of the coating site is lower than 5, higher than 35, and the relative humidity is greater than 80%. Construction should be prevented. The construction is finished with a medium coat, and after being dried, it is cleaned by grinding and then scraped with second middle coatings. The paint temperature should be maintained at around 20 C before construction.
Finish with epoxy shutoff primer. Spray or roll epoxy shutoff primer together on clean, flat cement floor. Characteristics of epoxy shutoff primer: Strong penetration and excellent adhesion, corrosion resistance, and good adhesion with intermediate or topcoat. Brushing requirements: in the primer should participate in a certain amount of diluent, so that the diluted primer can enter the bottom layer, enhance the adhesion of the coating and the bottom layer, the coating is necessary to connect, not interrupted, the amount of coating just full appearance. Part of the leakage coating can be brushed and applied, and the rest of the outer surface is primed before the construction of the humane process. Mix the two ingredients in batching and mix well, and use them after 20 minutes. The mixed coating will last for 8 hours, and it will be too long and easy to gel. The application of general curing agent construction temperature in 5 ~ 35 C, below 5 C need to use low temperature curing agent, otherwise can not carry out construction. The dry film thickness of epoxy primer is 10-15 micron m and the coverage is 0.14kg/m2.
