Photo 1:Place industrial or masking tape around the damaged area to prevent excessive shrinkage. While this may not be necessary for a fully adhered material, it is a good habit to get into, plus it aids in the protection of the seam while the seam treatment dries.

Protect repaired area until seam treatments have dried. Remove the tape surrounding the repair once the seam treatment has dried and the floor is ready for service.
