Wall/Ground Primer

Updated: 2026-07-23

Overview

Wall Grounding (墙固) and Floor Grounding (地固) are specialized construction materials used primarily in renovation projects. Wall Grounding is applied to walls to improve adhesion between the substrate and subsequent coatings like paint or plaster. Floor Grounding, on the other hand, is used on floors to enhance surface strength and prevent dusting. These products are essential for ensuring long-lasting and high-quality finishes in both residential and commercial buildings. Typically, these materials are water-based and environmentally friendly, making them suitable for indoor use. They are often tinted (e.g., green or red) to help workers identify treated areas. The ease of application and quick drying time make them popular among contractors and DIY enthusiasts alike.

Physical and Chemical Properties

Wall Grounding and Floor Grounding are liquid solutions with a density of approximately 1.0-1.2 g/cm³. They are water-soluble and designed to penetrate porous surfaces, forming a strong bond with the substrate. The materials are typically low in volatile organic compounds (VOCs), aligning with modern environmental standards. These products are stable under normal storage conditions but should be protected from freezing. Their key chemical properties include high adhesion strength and resistance to alkali, which ensures compatibility with common construction materials like concrete and plaster. The colored variants help in visual inspection to ensure even application.

Main Applications

Wall Grounding is primarily used to treat walls before applying paint, wallpaper, or other decorative coatings. It prevents peeling and improves the durability of the finish. Floor Grounding is applied to concrete or screed floors to reduce dust and strengthen the surface before laying tiles, laminate, or epoxy coatings. These products are widely used in residential, commercial, and industrial construction projects. They are particularly valuable in renovation work where old surfaces need reinforcement. Their versatility and effectiveness make them indispensable in modern construction practices.

Safety and Storage

Wall Grounding and Floor Grounding are generally safe to use, with low toxicity levels. However, it is advisable to wear gloves and avoid direct contact with eyes or skin. In case of contact, rinse thoroughly with water. Proper ventilation is recommended during application to minimize inhalation of vapors. Storage should be in a cool, dry place, away from direct sunlight and extreme temperatures. The products should be kept in their original containers with lids tightly closed to prevent contamination or evaporation. Shelf life is typically around 12 months when stored correctly.

B2B Procurement Guide

When procuring Wall Grounding and Floor Grounding in bulk, consider factors such as environmental certifications, compatibility with other materials, and supplier reliability. Look for products with low VOC content to meet green building standards. Price varies based on quantity and brand, with bulk purchases often attracting discounts. It’s advisable to request samples for testing before large-scale procurement. Ensure the supplier provides technical support and clear application guidelines to avoid misuse and ensure optimal results.
