The construction process and method of epoxy self-leveling floor

China Paint Online News Information: Self-leveling is a ground construction technology, it is a multi-material mixed with water liquid substances, poured into the ground, this material can be based on the ground's uneven flow, the ground is automatically leveled, and quickly dry, cured ground will form a smooth, flat, seamless new grass.1, construction preparation
(1) the main materials: epoxy self-leveling floor paint, basic treatment agent (bottom oil), surface treatment agent, fill and repair putty, fillers such as quartz sand, quartz powder. Epoxy leveling coating is currently mostly a two-part, should be fully mixed according to a certain ratio.(2) storage and storage: closed storage and transportation, to avoid packaging breakage and rain. Place in a dry and ventilated area to avoid high temperatures and strictly prohibit exposure and freezing in the sun. The storage period is 6 to 12 months at 5-40 degrees C.
(3) tool preparation: paint brush or roller, bucket, low speed mixer (400 s/min) or electric mixer gun, special nail shoes,knives, special tooth needle scraper, degassing roller. Construction tools need to be cleaned before use. After using the tool to clean up with water during dry solids time, so as not to affect the next use.(4) grass-roots treatment: the construction of grass-roots should be flat, rough, remove dust, old coating, etc., to C30 or more strength, and cut off water treatment, there must be no water, clean, dense. Cannot be loose soil, loose particles, gypsum board, paint, plastic, ethylene ester, epoxy resin, and adhesive residues, oil, paraffin, conservation agents and greasy and other pollutants attached. New poured concrete must not be less than 4 weeks, the shell needs to be repaired flat, dense substation needs mechanical polishing, and wash with water and vacuum cleaner to absorb loose surface particles, to be dried. Holes or grooves should be leveled with mortar or putty prior to 1 day ago, and super-high or protruding points should be removed or flattened to save material and improve construction quality.2, epoxy self-leveling construction method
(1) process
(1) cleaning substrate → (2) brushing bottom coating (interval time of about 30 minutes) → (3) preparation of self-leveling slurry → (4) pouring→ (5) Scraping surface layer → (6) special roller deblistering (in 20 minutes) → (7) self-flow plane to complete
(2) epoxy self-leveling construction process
a) bottom coating: the bottom oil added water at 1:4 dilution, evenly painted on the base surface. 1Kg base oil coating area of 5 square meters. Apply a self-leveling coating to a treated concrete substrate with a paint brush or roller, paint two layers, and add another primer to the old base. The first layer is dry before the second layer (interval of about 30 minutes). The dosage of the base coating is approximately 0.18 kg/m2 and the per barrel construction is approximately 110m2. Self-leveling work is carried out after the bottom coating is dried.b) slurry mixing: the first scale of 7 kg of water placed in the mixer, while stirring side to add epoxy resin self-leveling, until evenly do not see the grainy, and good liquidity, and then continue to stir for 3-4 minutes, so that the slurry uniform, static for about 10 minutes before use. If mixed with two packets at a time, then add 14 kg of water first, but only one pack, stir until evenly do not see particles, and then add a second pack.c) scraping surface layer: to the bottom oil half dry can be poured slurry, and with a toothed pusher or scraper to help expand, and control the thickness of the thin layer, and then to de-bubble roller treatment will become a high flat floor. Pour the stirring self-leveling mortar on the bottom-coated substrate, apply it once to the desired thickness, spread it out with aknife or a special tooth needle scraper, and then discard it with a degassing roller until it flows away. After the surface condenses, it does not need to be applied.d) such as local high, slurry can not flow to the place, can be gently scraped flat with a smear, level construction time is best completed in 30 minutes, after the construction of the implement side is rinsed clean with water.
) maintenance: 6 to 8 hours can walk at a temperature of 20 degrees C, the temperature is less than 5 degrees C, it must be 1 to 2 days. After curing, its surface is maintained with wax seal or brush surface treatment agent, which can be used after 2 weeks. The minimum maintenance period shall not be less than 1 week.: the specific construction
1) should refer to the design requirements and product instructions.
2) Ordinary self-leveling materials cannot be used directly on surface wear layers.
3) Do not carry out self-leveling construction when it is less than 5 degrees C, the construction temperature is 5-35 degrees C, the optimum temperature is 15 to 30 degrees C, before hardening should avoid the wind and sun.
4) when the construction has a bulge or splash, after the initial coagulation can bethe knife away.
5) other work is required on the self-leveling, should be carried out when it is hard to walk, if the use of the former slurry has been hard should be discarded, can not be stirred with water for re-use.
6) If there is a floor heating device should be turned off, wait for the ground to cool down before self-leveling construction.
7) The amount of ingredients to match the amount of construction, to avoid waste. Once the ingredients should be used up once, not diluted with water in the middle, so as not to affect the quality. According to the construction experience, a preparation of about 5Kg is appropriate.
8) Pedestrians are not allowed on the flow plane for a specified period of time.
9) during the use of paint must not cross-contamination, unmixed materials should be sealed storage.
Epoxy cement floor paint is mainly composed of epoxy resin, slurry, fillers (quartz powder, talcum powder, titanium white powder, etc.), additives (leveling agent, desmoticant) with the corresponding curing agent composed of special coatings, mainly used on cement floor. With good wear resistance, moisture-proof waterproof, oil-proof, dust-proof and so on, epoxy cement floor paint is mainly used in the electronics industry, packaging machinery, food and pharmaceutical, garage and other fields.Epoxy cement floor paint applicable places:
electronics, electrical appliances, machinery, communications, food, medicine, molds, clothing, plastics, tobacco, chemicals and other places requiring wear-resistant, impact-resistant places, especially the need to walk forklifts, heavy-duty trolleys, car places.
Epoxy cement floor paint features:
1, anti-impact, high load, wear resistance;
cement floor paint technical indicators:

epoxy cement floor paint construction process:

1, substrate treatment;
2, rolling oil;
3,scraping mortar coating;
4, scraping putty;
5, rolling brush surface coating or spray surface coating or sand casting for non-slip treatment.
5 to 20 years of use of epoxy cement floor paint, in a special region can be anti-static, anti-corrosion, high dust-proof construction.
