Liquid Rubber Mulch Glue is an easy solution to keep your landscaping products looking great and staying in place, season after season. Our Environmentally Friendly, Water-based formulation works well with Pine Straw, Cypress, Pea Gravel, Stone and Bark. It stabilizes the surface, improving resistance to erosion or displacement by wind and rain. It also locks in the color, minimizes dust, and remains permeable to allow for proper drainage.
