Concrete protective coating

Overview

• The concrete surface has been damaged due to various severe weather conditions. Our silicone coating exhibits excellent acid and alkali resistance, outstanding weather resistance, hydrophobic properties, stain resistance, freeze-thaw durability, and prevents cracking under thermal expansion and contraction

Product Features

• Silicone materials contain Si–O bonds with high bond energy, exhibiting excellent outdoor weather resistance and ultraviolet light resistance.
•  The coating is resistant to acids and alkalis, and can withstand various severe weather conditions.
• The coating surface exhibits hydrophobicity and excellent stain resistance.
• Resistant to freeze-thaw cycles; highly elastic, capable of adapting to thermal expansion and contraction without cracking.

Application Method

• Surface treatment: The coated building surface must be thoroughly cleaned of dust, foreign objects, etc., using air guns or water guns. For steel structures with existing coatings, the adhesion between the old coating and this product must be tested.
• Construction conditions: The construction temperature should be maintained between 5–35°C under adequate ventilation. Construction is strictly prohibited during adverse weather conditions such as rain, snow, fog, strong winds, or high humidity. Similar weather conditions should be avoided within 6 hours after commencement of work.
• Application method: Single-component paint; use directly after mixing. Recommended application rate: 0.35 kg/m²; number of application layers: 2; dry film thickness: 100 μm. The actual paint quantity should be confirmed by the laboratory according to requirements.
• Safety Instructions: The construction site is equipped with adequate ventilation facilities. Personnel must take protective measures, including wearing gloves, masks, and protective goggles. In case of accidental exposure to the eyes or skin, immediately rinse with water. Seek medical attention promptly if discomfort occurs. Smoking and open flames are strictly prohibited at the construction site.
