Use two beads of LIQUID NAILS Subfloor & Deck Construction for Extreme Temperatures (LN-902) between layers to achieve a long-lasting, impact-resistant structure. This product works well as a retaining wall adhesive because it bridges gaps to create a flexible bond that will withstand seasonal movement and temperature extremes. It's also easy to work with, providing 10 minutes of open time to allow for position changes.
Once dry, the wall adhesive will have locked the landscape materials into a single, unified wall that will add lasting appeal to the outdoor space to impress your customers and their guests long-term.
*Higher structures require professional engineering for safety reasons.
