**Which is the best sealing curing agent in Qingdao, Shandong?** Qingdao Dumai New Technology Co., Ltd. is a high-tech enterprise that integrates research and development, production, sales, design, and construction of environmentally friendly high-performance building and industrial flooring materials. **Lithium-based sealing curing agents** are all nano-grade materials with strong penetration capabilities, effectively penetrating the concrete surface and actively engaging in continuous chemical reactions with the concrete. The effective components of lithium-based sealing curing agents combine with free calcium, potassium, and other ions that can reduce concrete strength, generating a non-expanding, non-shrinking, stable chemical copolymer—hydrated calcium silicate—which fills the capillary pores in the concrete, making the entire concrete a dense, solid, dust-free, crack-free, breathable, and colorful whole. This achieves hardening, strengthening, dust-proofing, waterproofing, weather resistance, wear resistance, alkali resistance, chemical erosion resistance, salt resistance, oil stain resistance, and environmentally safe sealing effects. Moreover, as time goes by, the more fully the curing agent reacts with the cement, the higher the flooring strength. It ensures environmental safety, durability, and compressive wear resistance. **Application Scope of Concrete Sealing Curing Agents:** Requires a clean environment with certain dust content restrictions, but is not suitable for areas that need surface coating materials. Suitable for various ordinary concrete floors, wear-resistant floors, terrazzo floors, and mortar surfaces, both new and old concrete surfaces. For example: factory floors, warehouses, freight distribution areas, shopping centers, parking lots, service stations, and hangars, etc.
