What this sealer does

Henry HE107571 is a water-based asphalt dampproofer supplied in a 4.75 gal container. It forms a black protective coating on concrete or masonry surfaces. The product meets ASTM D1227 Type III, Class I standards for damp-proofing applications. It is intended for below-grade foundation walls and similar moisture-barrier work.

Check before you buy

Verify that the substrate is clean, structurally sound and above 50 degrees F before application. Coverage ranges from 3.0 to 100 sq ft per gallon depending on surface porosity and texture. This item cannot be shipped to California because it contains a chemical listed under Proposition 65. Confirm local VOC regulations allow a 0 g/L product.

Behaviour over a full job

Dry time spans 6 to 24 hours per coat, so plan the schedule around temperature and humidity. The water base allows tool clean-up with water while the material is wet. Sustained performance relies on achieving the recommended film thickness across the entire area. Multiple coats may be required on highly porous substrates.

Questions about this item

What comes in the 4.75 gal container and is any applicator included?

The container holds 4.75 gallons of water-based asphalt sealer; no brush, roller or sprayer is supplied so you must provide your own application tool.

When would I choose this 4.75 gal size over a smaller can?

Choose the 4.75 gal pail when you need to cover a larger area — each gallon yields 3.0 to 100 square feet depending on surface porosity.

How long before the black coating is dry enough for foot traffic?

At temperatures above 50 °F the film dries in 6 to 24 hours; cooler or humid conditions will extend that window.
