• Paintable — Compatible with both latex and oil-based paints after curing
• Sandable — Can be sanded smooth for a seamless finish

Application Notes: Apply in temperatures between 40°F and 150°F. For small repairs, one application is typically sufficient. For repairs deeper than 1/8", apply two or more layers, allowing each layer to dry fully before applying the next. Apply with a clean putty knife and ensure the surface is clean, dry, and free of debris before use.

The DAP 18787 Platinum Patch is sold in a convenient 32 oz container — ideal for larger repair projects where coverage and performance matter.
