Construction procedure

Construction method: brush coating, roll coating, airless spraying

Theoretical coating amount: 8-12 square meters /kg (single times) due to the actual construction surface roughness and dilution ratio of different, the amount of paint consumption is also different

Dilution: before use should be stirred evenly, in order to achieve the best brushing effect, roller coating, brush coating can usually be added to the paint 10%-15% volume of water according to the actual situation, at most 15% volume of water dilution this product. After mixing well, let it stand for 5 minutes before construction. If airless spraying is used, water dilution of no more than 5% of the volume of the paint can be used according to the actual situation, and stir evenly

Construction conditions: temperature > 5℃, humidity < 85%

Storage: Store in a cool, clean and dry place at 5-35℃. The remaining paint should be sealed and covered to prevent impurities from deteriorating paint. If the product is not opened and properly stored, the storage period is 12 months.

Tool cleaning: After stopping during painting and finishing painting, please clean all tools with clean water in time.

Recoating time: (30 micron dry film, 25-30℃) about 1 hour /25℃; Recoating interval ≥3 hours /25℃.

Repaint the wall surface: Build a new wall surface, remove the surface dust, greasy and loose plaster, if there are pores in time to repair, to ensure that the wall clean, dry and smooth;

Substrate surface state: remove the old wall is not strong paint film, remove the surface dust powder material and impurities, batch smooth and no loose material

Coating system: Ensure that the surface humidity of the pre-coated substrate is less than 10%, pH value is less than 10 before coating, the substrate layer should be accepted, qualified before coating construction coating system and coating times, in order to ensure the best paint film effect, strongly recommend the use of primer
