What points need to be mastered in the construction process of epoxy resin floor paint

The construction process of conventional crown epoxy floor paint is as follows: base treatment, sealing primer, epoxy mortar reinforcing layer, putty, and topcoat.

1) Base treatment: For the concrete floor with more oil stains, it can be washed with 10% 15% hydrochloric acid solution, and then rinsed with clean water; For the general concrete floor with a large area, it can be treated by using an electric mill to grind and remove sand dust and oil stains. (2) Back cover:

After the epoxy primer A and B components are evenly mixed, the roller is applied to the surface of the base layer, and it is best to roller coat it twice, so that it can be fully wetted and penetrate into the concrete to play a role in bonding and strengthening.

3) Middle layer mortar: add an appropriate amount of mixed quartz sand with different particle sizes to the paint and stir evenly, and use the plastering method to make the coating reach a certain thickness to enhance the impact resistance and rolling resistance of the floor.

4) Putty: After the mortar layer is fully cured, scrape two layers of putty, polish and smooth after drying, and provide a smooth and solid base surface for the surface coating.

5) Epoxy floor paint topcoat: The water-based epoxy topcoat is mixed evenly according to the mass ratio of component A and component B = 1 1, brushed or sprayed on the base surface, so that it is self-leveling, and after curing, it becomes a flat, smooth and multi-functional floor coating with anti-static, corrosion resistance, antibacterial sterilization, and odor removal.

1. The ambient temperature of the construction site should be higher than 5, and the relative humidity should be less than 80% before construction.

2. The builder should make more than a dozen records of the construction site, time, temperature, relative humidity, floor surface treatment, materials, etc., for reference.

3. After floor construction, the relevant equipment and tools should be cleaned immediately.

I think you don't know what this is, because the average family rarely uses floor paint, and such paint is generally used in large venues, underground parking lots in shopping malls or sports venues, etc., thenEpoxy resin floor paint construction processWhat are they? What are the key points of epoxy resin floor paint construction? If you want to know, let's take a look.

1. Epoxy resin floor paint construction technology.

1.Cleaning and inspection of the substrate: after vacuuming the substrate, check whether the substrate has cracks and empty shells, if there is, it must be deeply cut and cleaned and filled with epoxy resin mortar, because the epoxy resin does not allow water, so it can only be dry in the process of nuclear care, and can not be brutally beaten when cleaning, so as not to knock on the base layer on the edge;

2.Before construction, it needs to be kept clean, if there is debris adhesion, it needs to be removed, according to the correct proportion, the main agent and hardener are mixed, and fully stirred; Add an appropriate amount of mixed resin to quartz sand; Use a trowel to evenly coat the material; The mixed materials need to be completed within 30 minutes; Do a good job of handover at the construction handover; The curing and hardening time of the medium coating is about 8 hours or more.

3.It is used for spraying construction floor topcoat, with high efficiency, easy to obtain good decorative effect, and easy to control paint consumption; Spray pumps and nozzles must be selected according to the viscosity of the paint and the life of the paint to obtain the appropriate fluid pressure and flow rate. High-pressure airless sprayers, which are usually driven by electric or internal combustion engines, are widely used due to their good portability.

Second, epoxy resin floor paint construction points.

1.Avoid construction under low temperature and high humidity conditions; After the two-component material is mixed, it should be applied in a short time; After the coating is completed, it should be fully passed before it can be put into use; According to the flatness condition of the substrate and the requirements of use, the coating thickness is determined. The worse the flatness of the ground, the thicker the coating system is used, the greater the coating load, the thicker the coating should be, if the coating is too thin, it is easy to be damaged during use, such as the ground on the first floor also needs to do a good job of waterproof treatment.

2.The ground condition has a great impact on the quality of the final epoxy floor engineering, such as the ground condition does not meet the requirements, the epoxy project is difficult to do well, and in the process of epoxy floor use, there are often shelling, falling off, blistering and other phenomena, therefore, a good substrate is the premise of ensuring the quality of the epoxy floor engineering, and some ground does not meet the requirements of the epoxy floor coating, then this ground decoration method should not be selected.

3.Epoxy resin floor paint builders should make actual records of the construction site, time, temperature, relative humidity, floor surface treatment, materials, etc., for future reference. After the construction of epoxy resin floor paint, the relevant equipment and tools should be cleaned immediately.

Epoxy resin floor paint construction equipment and construction tools.

Generally, our local buildings will use paint, so what are the construction techniques and construction points of epoxy resin floor paint, through the above introduction, we also understand these, so if you still want to know more decoration information, please continue to pay attention to it.

Epoxy resin floor coating construction process 3, construction process primer: the primer oil is diluted with water at 1:4, and evenly brushed on the substrate.

The coating area of 1kg primer is 5 square meters. The slag balance is applied to the treated concrete base surface with a paint brush or roller, and two layers are painted, and one more primer needs to be added to the old base layer. The second layer can be applied only after the first layer is dried (with an interval of about 30 minutes).

The amount of primer is about 110m2 per barrel. Self-leveling is applied after the primer is dried. Slurry mixing:

Weigh 7 kg of water and put it in the mixer, add epoxy resin self-leveling while stirring, until it is uniform and no granularity, and the fluidity is good, and then continue to stir for 3-4 minutes to make the slurry even, and stand still for about 10 minutes before use. If you mix two packets at a time, add 14 kg of water first, but only add one packet first, stir until there are no particles, and then add a second packet. Scraping the surface layer:

After the bottom oil is semi-dry, the slurry can be poured, and the toothed pusher or scraper can be used to help, and the thickness of the thin layer is controlled, and then the defoaming drum is treated to form a high level floor. Pour the evenly stirred self-leveling mortar on the base surface of the primer, apply it once to reach the required thickness, and then flatten it with a trowel or a special tooth needle such as a blue scraper, and then give it up with a deflated roller and wait for it to flow freely. Once the surface has condensed, there is no need to apply it again.

The dosage standard is shown in Table 5Table 5 Surface coating scale Base surface flatness Thickness (mm) Dosage (kg m2) Differential surface leveling 2 About General surface leveling 3 About Standard full-space leveling 6 About Severely uneven matrix leveling 10 About 16 If the local area is too high, the slurry can not flow to the place, you can use a trowel to gently scrape it, the leveling construction time is best completed within 30 minutes, and the machine after construction is washed with water. Conservation:

When the temperature is 20, you can walk for 6 8 hours, and if the temperature is lower than 5, it will take 1 2 days. After curing, the surface is cured with wax seal or brush surface treatment agent, and it can be used after 2 weeks. The minimum curing period shall not be less than 1 week.
