  • 1 Gal (12 Lbs / 5.44 Kg).

  • 5 Gal (60 lBS / 27.20 Kg). 

Stuccolastic it’s excellent for crack repairs. It provides a durable, flexible matrix when properly applied that most paints will adhere to. Stuccolastic is ready to use. No mixing is required.

  1. Use a margin trowel or putty knife to apply Stuccolastic. A narrower blade provides better pressure for filling the compound into the hairline cracks. Apply Stuccolastic in short passes perpendicular to the hairline cracks.
