Damp Proofing your home

Choosing the right foundation coating

There are two types of foundation coatings to choose from:

Water-based asphalt emulsion coating
For cost-effective, long-lasting protection, choose water-based Henry 107 Asphalt Emulsion. Henry 107 is a protective coating that will last longer than solvent-based coatings, but needs to be applied under good conditions. The surface must be very clean, and you must have two days of dry, warm weather (over 50°F) since asphalt emulsions become water resistant only after drying thoroughly.

Do not apply if the air temperature is below 60°F, or if there is threat of rain or temperatures below 40°F within 48 hours. Make sure the entire job is fully cured before backfilling with dirt, and avoid scraping or damaging the coating.

Solvent-based asphalt coating
For less-than-perfect conditions, choose solvent-based Henry 101 Unfibered Roof & Foundation Coating.

With Henry 101, you will have no worries about low temperatures or rainfall after application. Solvent-based coatings can be applied in colder temperatures (as low as 32°F), can be rained upon within two hours of application, and can actually eat through a fine layer of dust to “grab” the surface.
