For exterior applications over cement or masonry, we recommend using a high-quality polyurethane construction adhesive (such as PL Premium or similar) along with mechanical fasteners for added security. Make sure the surface is clean, dry, and free of dust or loose material before installation.
Also, for exterior use, be sure to properly seal all seams, edges, and fastener penetrations with a suitable exterior-grade sealant to prevent moisture intrusion.
If you have specific project conditions, feel free to reach out and we’re happy to provide more detailed guidance.
