Surface preparation: ● Ensure the surface is clean, dry and free from stains. Remove laitance and debris by appropriate methods and remove dust;
● Substrate pH <12, concrete moisture content <6%;
Recommended number of coats: ● Apply 2 coats; the number of levelling coats shall be determined according to substrate roughness and void ratio;
● The first coat removes air bubbles and levels the surface, then dry; when treating large defects, an appropriate amount of quartz sand may be added to the first putty coat; ● The second coat provides a smooth surface finish; ● Only trowel application is permitted.
Subsequent coat: water-borne acrylic coating, solvent-borne epoxy coating, polyurethane topcoat, etc.

| Squeegee application | 0~5% | Spatula, trowel or putty knife |
● Ensure ventilation and air extraction during application to facilitate water evaporation;
● Wear a mask, gloves and other protective equipment correctly;
● Mix according to the curing ratio, and adjust the thinner amount to mix thoroughly and uniformly;
● The substrate temperature shall be at least 3 °C above the dew point, with a moisture content < 6%;
● The ambient temperature shall be controlled at 5–35 °C, and the relative humidity shall not exceed 85%; where possible, indoor application is preferable to ensure coating appearance
quality.
● All work related to the application and use of this product shall be carried out in accordance with the relevant national health, safety and environmental standards and regulations;
● For putty sanding operations in confined spaces, effectively implement air extraction/ventilation measures for the working environment and use sanding tools with dust extraction;
meanwhile, personnel shall avoid skin exposure as far as possible (apply protective ointment or cream to exposed areas to reduce skin absorption of harmful dust);
● If in doubt about the suitability of this product, consult the company;
