Henry 788 Asphalt Dampproofing 5 Gallon Bucket

Henry 788 Non-Fibered Asphalt Dampproofing is designed for protecting below-grade foundations and walls. It’s also effective above-grade, providing a moisture barrier for exterior walls in cavity wall construction. Made with asphalt, bentonite clay, and water, it’s free of solvents and is effective on “green,” uncured, or damp surfaces.

Key Features and Benefits:
– Moisture Resistant: Protects against moisture infiltration, whether above or below grade.
– Durable and Flexible: Resilient in harsh conditions without cracking, running, or sagging.
– Multi-Purpose: Ideal for below-grade dampproofing, as a weather-resistant barrier, and for lining concrete planters.
– Corrosion Resistant: Suitable for metal surfaces, protecting against corrosion with just a single coat.

Applications:
– Below-grade dampproofing of walls and foundations.
– Dampproofing gypsum wallboard assemblies and exterior walls in cavity wall construction.
– Sealing concrete and masonry planters.
– Henry 788 Provides a moisture barrier on both uncured and damp surfaces.

Installation Tips:
– Preparation: Ensure surfaces are clean and free of contaminants. Minor repairs can be made with a 1/16″ coat of emulsion.
– Application: Stir the Henry 788 coating thoroughly and apply it to damp surfaces for best results. Apply the emulsion with a brush or heavy-duty spray equipment.
– Drying: Typically dries within 8 to 12 hours in warm, dry weather, but can take 2 to 7 days in cooler conditions. Allow at least 24 to 48 hours to cure before backfilling.

Precautions:
– Do not apply when temperatures are below 50 °F or if rain or freezing temperatures are expected within 24 hours.
– Fresh coating can be cleaned with water; dry material requires kerosene or mineral spirits.

Henry 788 Non-Fibered Asphalt Dampproofing is a robust solution for protecting building foundations and walls from moisture, suitable for both above and below-grade applications.
