How to Bond Aluminum to Cement
- 1). Strip any paint off of the concrete. Brush the concrete surface with a thick layer of soy-gel paint stripper. Layer the gel up to 1/8 inch thick. Allow the gel to dry and harden for up to 12 hours. Remove the gel off with a paint scraper.
- 2). Apply a thick layer of Liquid Nails Metal Projects Repair Adhesive (LN-203) to the surface of the aluminum and concrete. Firmly press the aluminum into place on the concrete. Follow the Liquid Nails label instructions for details on application.
- 3). Clamp the bond together with C-clamps or a vice for up to 24 hours.
