Epoxy self-leveling floors are clean, beautiful, easy to clean, antibacterial and wear-resistant. They are often designed for places with high cleanliness requirements, such as pharmaceutical factories, food and beverage plants, and precision electronic equipment production plants. Here we take a look at some of the relevant knowledge of epoxy self-leveling floor.
Epoxy self-leveling floor use matters needing attention
1, construction temperature ≥ 5 °C, in order to < 5 °C construction, use a special formula. Humidity is recommended for construction below 75%.
2. Ensure air circulation during construction. Do not exceed 30 minutes when modulating usage.
3, the construction process to do maintenance work to prevent intrusion of dust, debris, affect the paint effect.
4. After the construction is completed, it needs to be maintained for at least 7 days before it can be put into use. During the period of conservation, in particular, there must be no infiltration of water or various solutions.
5. Do not mix in other paints.
6, must be strictly in accordance with the prescribed proportion of adding curing agent.
7. Keep the surface of the object to be cleaned. The moisture content of the object must be less than 7%.
8. Keep the painting environment clean, and it is forbidden to work in a dusty environment.
Epoxy self-leveling floor features
1. The coating thickness can reach 1.5-10mm according to the requirements, and the design requirements can be achieved by adjusting the thickness of the middle coating and the thickness of the surface layer;
2. The middle coating should be coated with a putty knife (if the coating requirements are thin) or using quartz sand to prepare the resin mortar, using a knife coating (usually 1-3mm, using a flat-bottom scraper scraper), trowel coating (coating design thickness When used, flattened with a spreader, smoothed by a trowel, or self-leveling trowel (coated with a guillotine or self-leveling rake), can be thicker or thinner, when compared to the cost of the first two methods. High, but flatness is good) The method is applied to a certain thickness;
3, the surface layer of solvent-free epoxy self-leveling floor coating, the use of serrated trowel paint, and now there are companies in order to save expensive topcoat, and the use of high pressure airless spray method (certain thickness is not high). In general, if the owner has no thickness requirements for the surface layer, use a serrated trowel to construct a surface layer thickness of about 0.7-1mm, of course, can also be thick coated as required.
Epoxy self-leveling floor construction process
1. Primer: After the base oil is well-distributed, brush evenly on the base surface. 1Kg base oil coating area is about 5m2. Use a paint brush or roller to apply a self-leveling primer to the treated concrete base and apply two coats. Add another primer to the old base. After the first layer is dry, the second layer can be painted (interval 30 minutes or so). The amount of primer is about 0.18kg/m2, and the construction can be about 110m2 per barrel. After the primer has dried, it is self-leveling.
2. Slurry Mixing: Mix the epoxy resin self-leveling floor coating according to the ratio and the thin material, and mix until uniform, no granular, and good fluidity. Continue stirring for 3-4 minutes to make the slurry even and static. It can be used in about minutes. Stir mixing can be done in batches.
3. Scrape the surface layer: After the semi-dry base oil is poured, the slurry can be poured, and the blade can be assisted with a tooth push knife or a scraper, and the thickness of the thin layer can be controlled, and then the defoaming roller can be used to treat the high leveling floor. . Pour the evenly-disturbed self-leveling mortar onto the primed base surface. Apply once to the desired thickness, then use a guillotine knife or special tooth needle scraper to flatten it, and then let the deflation cylinder deflate and let it flow. After the surface has condense, do not apply it again.
4, if the local is too high, the slurry can not flow to the place, you can use a trowel to gently scrape flat, leveling the construction time is best completed in 30 minutes, after the construction of the equipment that is washed with water.
5, curing: temperature 20 °C, 6 to 8 hours to walk, the temperature is lower than 5 °C, it must be 1 to 2 days. After curing, the surface is cured with a wax seal or brush surface treatment agent and can be used after 2 weeks. The minimum maintenance period should not be less than 1 week.
Summary: The above is the content of precautions for epoxy self-leveling floor coatings introduced by Xiao Bian for everyone. I hope we can help you effectively. If you have any good suggestions, look forward to communicating with Xiaobian. More information Please pay attention to this site.
