  1. Ensure cap is closed and sealed, and shake well before use
  2. Mask off any surfaces not intended to be treated
  3. Liberally apply an even coat using a paint pad, roller, brush, or low-pressure sprayer. 
  4. Allow sealer to penetrate the surface for 10-15 minutes. During this time, keep the surface wet with sealer, adding more sealer as needed. DO NOT ALLOW SEALER TO COMPLETELY DRY ON THE SURFACE.
  5. Thoroughly wipe dry the entire surface with clean absorbent towels.
  6. A second coat may be needed for porous, absorbent surfaces. If a second coat is required, it should be applied within 30-40 minutes from the initial application as directed in steps 3-5.
  7. Should a sealer residue appear, re-wet the impacted section of the surface with sealer. Agitate the surface with a white nylon scrubbing pad to loosen residue and wipe dry with a clean, absorbent towel.
  8. A full cure is achieved in 24-72 hours. Use of the treated surface may resume in 6-8 hours. If use of the surface must resume sooner, cover the treated surface with red rosin paper to protect it until full cure is achieved.
  9. Clean tools used during application with water.
