Non-Fibered Emulsion Dampproofing for Below-Grade Masonry
BULLDOG® Non-Fibered Emulsion Dampproofing #42 is a brush- or spray-grade asphalt coating emulsified with water and agents. Contractors use this non-fibered emulsion dampproofing on exterior masonry below grade when a heavy coating is not required. It can adhere to new, green, or slightly damp masonry surfaces.
Built for Light-Coat Below-Grade Applications
This coating provides a practical option for exterior masonry walls below grade. Because it is designed for situations where a heavy coat is unnecessary, crews can apply it by brush or spray. The water-based emulsion may require slight stirring before use.
Recommended Uses
- Dampproofing exterior masonry below grade
- Coating new or green masonry surfaces
- Application to slightly damp masonry
- Projects where a heavy dampproofing coat is not required
Non-Fibered Emulsion Dampproofing Application Guidance
Apply the coating by brush or spray to a slightly damp surface. Use approximately 2½ gallons per 100 square feet (1 liter per square meter). Apply only when the temperature is 50°F and rising. At the recommended rate, the listed dry time is approximately 24 hours.
For below-grade work, wait 48 hours before backfilling. Keep the product from freezing during storage. After application, clean tools with mineral spirits or BULLDOG® #99 Asphalt Remover. Review the job conditions before work begins and follow the container instructions and Data Sheet guidance.
