NanoTech Materials Skylight Sealer is a 100% acrylic, UV-resistant, water-based glaze designed to restore and protect weathered skylights. This rapid-drying formulation provides excellent resistance to dirt pickup, chalking, and environmental weathering while creating a clear, protective barrier over aged surfaces.
OUTSTANDING FEATURES:
- 100% acrylic UV-resistant technology
- Excellent resistance to dirt pickup, chalking, and weathering
- Rapid drying water-based formulation
- Clear protective finish
- Easy brush, roll, or spray application
RECOMMENDED USES:
Skylight Sealer is designed as a dirt-resistant and protective glaze coat for the restoration of weathered skylights.
APPLICATION:
- The surface must be clean, dry, and free of loose particles or foreign matter.
- If applying over freshly applied coatings, ensure they are completely cured prior to Skylight Sealer application.
- Skylight Sealer may be brushed, rolled, or sprayed onto a clean, dry surface. If spraying, material temperature
should be at least 50°F.
APPLICATION PROPERTIES:
| Coverage / Yield | 3 dry mils (1 gal per 200 sq ft) |
| Dry Time (75°F) | 2 to 3 hours |
| Recoat Window | 2 to 3 hours |
| Complete Cure | 5 days |
COVERAGE RATE:
- Apply Skylight Sealer at a rate of ½ gallon per 100 sq. ft. (8 wet mils).
- Surface texture and wind conditions may affect applied mil thickness.
ENVIRONMENTAL CONDITIONS:
This product cures through water evaporation.
- Do not apply when ambient temperature is below 50°F.
- Do not apply if temperatures may fall below 32°F within 24 hours of application.
- Do not apply if rain or dew is expected before the coating dries.
- Avoid late afternoon applications in high humidity conditions to prevent overnight dew formation and potential
wash-off.
- On marginal weather days, apply multiple thin coats to ensure proper drying before rain or freeze conditions.
LIMITATIONS:
- Surface must be clean and dry prior to application.
- Not recommended for roofs with slopes less than 1/8” in 12 or where ponding water is present.
- Do not apply over wet substrates.
- Do not apply when inclement weather is imminent.
- Complete cure requires full water evaporation. Cool temperatures and high humidity will extend cure time.
