Our gravel binder is carefully formulated with acrylic emulsion and polyvinyl alcohol. Designed specifically for repairing surface gravel to prevent scattering and settlement, making courtyards and paths neater and more beautiful. The usage method is extremely convenient: 1. Use a sprayer to evenly spray the product onto the surface of the stone or covering. 2. Use a rake to turn the surface over to ensure that the adhesive is covered more evenly. 3. Spray another layer to ensure full coverage. Gently press the surface with a spatula and let it air dry and solidify naturally. The required time is 12 to 36 hours. And it can effectively connect gravel, stones and rocks to enhance structural stability and prevent loosening and displacement. Under normal climatic and usage conditions, its curing time is relatively long, making it suitable for various outdoor landscape projects.
