Construction Conditions
- Base surface requirements: The concrete base surface should be cleaned, repaired flat, and polished to a certain roughness. Ensure that the concrete curing is completed and the strength reaches C25 or above, with a moisture content below 8%. After processing the base surface, the next process should be carried out as soon as possible.
- Environmental temperature and humidity requirements: The environmental temperature at the construction site should be above 5 ℃, and construction can only be carried out when the relative humidity is less than 85%.
- Ventilation conditions: Ventilation should be maintained during construction.
Construction Methods and Requirements
-
1
Before use, pour component B into a mixing bucket and add the corresponding mass of component A by electronic weighing in proportion. Stir thoroughly for 2–3 minutes to prevent uneven mixing at the bottom of the bucket and local non solidification of the floor. Ready to use and prepare; the prepared polyurea self leveling should be used up within 15 minutes.
⚠ Attention: The mixed material should not be placed in the bucket. It should be poured onto the foundation of the construction to avoid rapid solidification of the material.
- 2 During construction, in order to ensure interlayer adhesion, polishing treatment should be carried out (note: polishing floating dust must be cleaned with a vacuum cleaner). Then, a solvent-free epoxy sealing primer should be applied by rolling. After the primer is completely cured, the polyurea self leveling composite material should be mixed evenly in proportion. Then, pour this composite material onto the floor and scrape it evenly with a trowel (3mm or 5mm trowel can be selected according to thickness requirements).

After the surface is completely dry — normally about 12 hours — please add the colored PU topcoat. Mix the two components of topcoat A and B thoroughly for 2–3 minutes, and then apply them evenly on the floor using a high-quality, non-depilatory short hair roller. Suggested coating area: approximately 0.2 kgs/m².
⚠ Attention: During construction, adhere to the principle of "dedicated personnel for ingredient preparation", "multiple shortages and continuous supply". The paint should be used up within 30 minutes.
- 4 Using tools: Dust free grinding machine, industrial vacuum cleaner, angle grinder, airless spraying machine (optional), steamed bun knife, roller barrel, defoaming drum, brush, measuring instrument, electric mixer, textured paper, etc.
- 5 In order to prevent contamination of the construction edge and maintain a completely straight line at the processing area, protective tape should be applied, and the ingredients should be kept clean to avoid impurities. Construction equipment and tools should be kept clean.
- 6 Try not to arrange construction on summer nights to avoid mosquitoes falling and affecting the surface aesthetics of the coating.
- 7 Do not pour self leveling materials into the sewer.
- 8 Smoking is strictly prohibited at the construction site.
- 9 Under normal circumstances, the paint film should be cured for at least 7 days after completion of painting to ensure optimal performance of the paint film.

Frequently Asked Questions (FAQ)
Q
What is SRT-AB self-leveling cold polyurea floor material?
SRT-AB self-leveling cold polyurea floor material is a 100% solid content, solvent-free, two-component coating system (Component A + Component B) that cures at room temperature. It provides a seamless, dense, and highly durable floor coating suitable for industrial and commercial applications.
Q
How long does it take for the polyurea floor material to cure?
The surface becomes dry within 2 hours at room temperature. Full surface dryness is achieved within ≤8 hours, and actual/complete dryness occurs within ≤24 hours. For optimal paint film performance, a full cure of at least 7 days after painting is recommended.
Q
Is this polyurea floor coating environmentally friendly?
Yes. The product is 100% solid content with zero VOCs (volatile organic compounds), free from solvents and heavy metals, and can be transported as a non-hazardous material. It is a safe and eco-friendly flooring solution.
Q
What are the mixing ratios and pot life of the material?
Component A and Component B are mixed in a specific mass ratio (A: 16 kgs per drum, B: 4 kgs per drum). After mixing, the working time (pot life) is approximately 10–15 minutes. The prepared polyurea self-leveling material must be used up within 15 minutes to avoid premature solidification.
Q
What are the substrate and environmental requirements before construction?
The concrete substrate should have a strength of C25 or above, with a moisture content below 8%, and must be cleaned, repaired, and polished before application. The ambient temperature should be above 5°C and relative humidity below 85%. Adequate ventilation must be maintained throughout the construction process.
Q
How should the polyurea floor material be stored, and what is its shelf life?
The product should be stored in a dry, cool, and well-ventilated environment, away from direct sunlight, rain, and fire sources. Under original packaging and specified storage conditions, the shelf life is 12 months from the production date. Once opened, use as soon as possible; if unused, reseal and store properly.
