The Footwear Care Cement Glue is a strong multi-purpose glue used that is used for repairing shoes. Before repairing clean the area with Deglazer. Apply a first coat of the adhesive to both surfaces. Let the glue dry for about 1 to 3 minutes keeping the two sides apart. Once the first coat of glue is dry, apply a second coat of adhesive to both sides of the rip. Allow the second coat to dry for about 10 minutes. Push together and use a weighted object to keep pressure on the repair while it dries and seals. The seal dries within 2 to 3 minutes, but the seal will form more fully if you allow it to dry for at least 6 hours. The best option would be to allow it to dry overnight.
