water-based acrylic floor paint
1. Key preparations before construction
Surface treatment: New concrete needs to be cured for more than 28 days, with a moisture content of ≤6%, and oil stains and floating slurry should be removed. The old floor needs to be polished to a solid base, and acid washing should be used to neutralize the alkalinity if necessary.
Environmental requirements: Construction temperature ≥10℃, humidity 30%-70%, avoid rainy season or high temperature exposure to prevent bubbling or sagging of the paint film.
2. Standardized construction process
Primer sealing: Roll on penetrating primer (such as epoxy sealing primer) to enhance adhesion and seal pores, with a dosage of about 6-8㎡/kg.
Middle coating leveling: Mix quartz sand (80-100 mesh) and floor paint and scrape to increase thickness and compressive strength, with a dosage of 3-4㎡/kg.
Top coating decoration: Roll or spray in two passes to ensure uniform color, each pass is about 25 microns thick, and the total dosage is 4-5㎡/kg.
Surface protection (optional): Spray silicone acrylic topcoat to improve gloss and stain resistance.
3. Construction precautions
Dilution ratio: Mix according to product instructions, excessive water addition may cause sagging or reduce performance.
Interlayer drying: Each coat needs to be completely dry (usually 2-8 hours) to avoid the next process when it is not completely dry.
4. Maintenance and acceptance
Maintenance period: Under 25℃ environment, it can be walked on for 48 hours and can be used normally after 7-10 days. Low temperature or high humidity requires extended maintenance time.
Acceptance criteria: paint film has no hollows, uniform color, and meets water resistance test (no peeling after 72 hours of immersion) and hardness test standards.
