Preparation

  • Seal-Once is designed to be applied over untreated concrete/masonry surfaces.
  • Smooth horizontal concrete may need to be etched to enhance penetration. Test area with water, if penetration occurs apply Seal-Once.
  • Surfaces must be sound and clean. Seal-Once will not fill voids or bridge cracks. Repair all defective concrete/masonry to structurally sound surfaces. Caulk all expansion joints, flash roofing and control joints as required.
  • Seal-Once can be applied within an hour of repair.
  • Clean all dirt, dust, oil, grease, mold and mildew, efflorescence, curing compounds, form release agents, paint and any other materials that may affect penetration.
  • Power washing with New Image Coatings™ Concrete/Masonry Cleaner will ensure proper surface preparation. After cleaning oil and grease spots, sprinkle a little water on the cleaned surface to check for contamination. If the water is quickly absorbed the surface is clean. If the water beads, oil and grease are still present. Efflorescence must be washed off with New Image Coatings Re-New Concrete.

Application

Vertical Surfaces

  • Apply one even coat from the bottom up with a garden sprayer, brush, air assisted  or airless sprayer. Use medium spray fan pattern.
  • Apply second coat as soon as first coat has penetrated the surface (wet on damp — not wet on wet). Do not use a roller. An additional third coat may be needed on very porous surfaces.
  • Do not use if air or surface temperature is below 35°F/1.67°C.
  • Do not apply in rain or when rain is imminent.
  • For best results, apply in the evening, out of direct sunlight, at cooler temperatures.
  • When applying in direct sunlight and over hot surfaces, spray with a mist of water then apply Seal-Once immediately on dampened surface.
  • Do not use with other waterproofing products.
  • Overspray: Clean windows when Seal-Once is still wet. Brush out any puddles.

Horizontal Surfaces

  • Apply with garden sprayer, brush, air assisted or airless sprayer. Use medium spray pattern.
  • Apply second coat as soon as first coat penetrates the surface.
  • Avoid puddling or ponding; brush puddles to evenly coat surface until Seal-Once thoroughly penetrates.

DRYING TIME
Allow water to evaporate before subjecting surface to light foot traffic; 2-3 hours is sufficient, depending on temperature and humidity.

CLEAN UP
Clean equipment and brushes with warm, soapy water. Store unused product above 32°F, protect from freezing.
