How to apply
- Ensure the surface is clean, dry, and free of loose debris or old sealant.
- Stir the Cement to achieve a uniform consistency; use a stiff putty knife or trowel.
- Apply in thin, even coats directly onto the damaged area, feathering the edges to blend with the surrounding roofing.
- Allow the first coat to set before applying additional coats for reinforced sealing as needed.
- Store the can tightly closed when not in use to preserve the remaining material for future patches.
