As Limeijia’s flagship exterior product, our sand-in-water coating is widely acclaimed for its realistic stone-like texture and visual appeal. A strict, standardized construction process is key to achieving outstanding decorative effects and long-lasting performance. With 30 years of experience in coating manufacturing and engineering services, Limeijia has developed a refined, efficient application procedure. Covering everything from base treatment to final protection, this system combines professional precision with easy operation, making it perfectly suited for all kinds of large-scale architectural projects.Sand-in-water Coating
Step 1: Apply one coat of transparent primer by roller or spray. With Limeijia’s dedicated primer, achieve full and even coverage to seal the substrate’s pores and boost adhesion for the following sand-in-water coating layers. This vital step effectively guards against efflorescence and blistering, laying a stable base for the whole coating system. Let the primer dry completely as per product instructions to ensure full penetration into the substrate.
Step 2 (Optional): Layout and MaskingAccording to the project’s design specifications, use line coating to mark wall contours and apply masking tape to section off the surface. This step not only elevates the aesthetic effect of the exterior wall but also effectively prevents coating cracking caused by thermal expansion and contraction. Ensure that lines are straight and spacing is uniform throughout. The masking tape must be removed promptly after Step 4 to avoid peeling or damaging the sand-in-water coating finish.
Step 3: Apply one coat of Background Coating by roller or spray. Apply the specified matching color evenly across the entire surface with no uncovered areas. The color should be well-coordinated with the main hue of the sand-in-water coating, forming a unified base that supports the realistic stone-like effect. After drying, check the surface for flatness and fix any defects promptly to guarantee a perfect and consistent finish.
Step 4: Spray two coats of Sand-in-water Coating.As the core step of the entire construction process, apply a thin first coat as a base layer using professional spraying equipment. After it dries, apply the second coat to achieve uniform thickness and dense particle distribution, fully presenting the natural stone texture and rich three-dimensional effect. During application, strictly control air pressure and spraying distance to avoid issues such as sagging or uneven coverage.
Step 5: Apply one coat of Finish Coat by roller or spray.After the Sand-in-water Coating is fully dry, apply the dedicated protective topcoat across the entire surface. This forms a dense protective film that enhances the coating’s weather resistance, waterproof performance and stain resistance. It also enriches the gloss, keeping the realistic stone-mimicking effect vivid and long-lasting for many years.
This simplified procedure is straightforward, efficient, and highly controllable, making it ideal for both large scale construction and high precision detailing. Limeijia’s standardized application system for sand-in-water coating brings ease and reliability to high-end exterior decoration. By integrating exceptional product performance with professional construction guidelines, it has become a preferred solution for architectural facades around the world.
