Product Description: Multi-functional alkali-resistant, high-permeability water-based sealing primer developed from silane-based materials. It can effectively seal the wall, has the functions of one-way ventilation, alkali resistance and weather resistance, high adhesion, etc., especially has a good penetration protection effect on fair-faced concrete.

Product characteristics: Silane mixture, transparent primer composed of fine particles, excellent water resistance and water-soluble inorganic salt anti-saponification performance. Strong penetrating power, effectively sealing and strengthening the base layer; can evenly and reduce the capillary water absorption of the base layer, and improve the film-forming quality of the surface coating film; one-way breathable and hydrophobic and does not hinder the outward diffusion of internal water vapor.

This product is water-based and environmentally friendly, with low volatile emissions and no pungent odor.
Scope of application: All mineral substrates and solid old coating surfaces inside and outside buildings, such as all kinds of cement mortar plastering surfaces, concrete, lime plastering surfaces, gypsum products, cement bricks wait. Ideal for highly alkaline concrete surfaces, ensuring long-lasting aesthetics of the finish.

Before construction, the dust, grease and mildew on the wall must be removed. The loose old coating should be eradicated, and the pinhole cracks on the wall should be filled and leveled. If there are fungi and mildew growing on the wall surface, the wall surface should be cleaned with mold removal solution first, and then washed with water, and the paint can be applied after drying. The new wall must be fully dried and maintained for at least 30 days to ensure that the pH value of the wall is lower than 10, and the moisture content of the base layer of the wall is less than 10%.
