Epoxy cement sealing primer is specifically designed for protective coating of cement and concrete structures, suitable for walls, floors, etc. It offers strong adhesion to the substrate and excellent sealing properties, making it a specialized primer for such substrates. Epoxy cement sealing primer is a two-component coating that requires a dedicated curing agent and can be applied by spraying or rolling.

The primer has good permeability, allowing it to penetrate into the pores of cement and concrete, providing excellent sealing.

Strong Adhesion

It adheres firmly to the substrate, ensuring a strong bond without film peeling, effectively protecting the substrate surface.

Excellent Alkali Resistance

This paint offers outstanding alkali resistance, making it particularly suitable for alkaline cement and concrete structures.

Good Application Properties

It can be applied by spraying or rolling, with excellent workability, achieving good results even with low film thickness requirements.

Epoxy cement sealing primer is a specialized primer for cement and concrete surfaces, widely used in building walls, floor surfaces, concrete structures, and other areas, paired with dedicated intermediate and top coats.

Surface Preparation

① The plaster layer or concrete surface (including joints, around window frames, etc.) must be free of contaminants. ② The substrate surface must be firm, without looseness, cracks, or blistering, with flatness ≤2mm, and free of dust or adhered particles. ③ For plaster and concrete substrates, the moisture content must not exceed 10%, and the pH must not be higher than 9. Newly plastered cement mortar walls require curing for at least 10 days in summer and 20 days in winter; cast-in-place concrete walls require curing for at least 21 days in summer and 28 days in winter.
