Questions and Answers for Henry 101 Non-Fibered Black Foundation Coating 4.75 gal.

A:  Tomm, we are not sure of what you need to accomplish here. The application of a product like Henry 101 Non-Fibered Foundation Coating to a surface that is crumbling will not fix the issue. While you could apply Henry 101 it would be similar to painting over sawdust. Henry 101 Foundation coating should only be applied to a surface that is in good sound condition.

A:  Jose, Henry 101 Non-Fibered Black Foundation Coating can be sprayed on if you have a heavy duty spray rig, such as a Graco 733 or equal, able to produce at least 2,000 PSI and spray 2-4 gallons per minute, ½” ID hose with a .040-.060 tip.

A:  David, Henry 101 Non-fibered Foundation coating would be used over a water based sealer if you needed to apply it in temperatures lower than 50 degrees. Solvent based products like Henry 101 can be applied at 40 degrees.

A:  Isrosa, we estimate the DFT or dry film thickness at about 6.4 to 8 mils per application. All liquids will be a 16 mils wet film thickness if one gallon is spread over 100 square feet. DFT is calculated by taking the wet film thickness times the % of solids by volume. The DFT is the solid content left on the surface after the liquid has gassed off or evaporated. So if the solids by volume of the liquid is 16 mils thick on a 100 square foot area and the solids by volume of the product is around 40 to 50 % then the calculation would be 16 X 40% = 6.4 mills or 16 X 50% = 8 mils. If you need an EXACT mil thickness for specifications please contact productsupport@henry.com. The recommended coverage of Henry 101 is 1.5 to 2 gallons per 100 square feet. If you applied 2 gallons per 100 square your mil thickness would be roughly 12.8 to 16 mils.

A:  ReidMac, we don't recommend using Henry 101 for your project. The solvents in the HE101 could soften the existing asphalt ( Tar ) and may not adhere well. You can use Henry 107 Asphalt Emulsion Sealer and Dampproofer for this project though since it is not solvent based.

A:  Ryan, Henry 101 can be used to dampproof above and below grade exterior concrete and masonry walls and foundations that are thoroughly dry. Brick is considered masonry.

A:  Steve, Henry 101 Non-Fibered Foundation coating should NOT be used on the interior of a basement. Henry 101 is an exterior product only. If you need to dampproof your basement there are products such a Drylock that is an interior product and is found in the paint department in Home Depot. Your best bet would be to consult with the paint specialist at your local Home Depot for interior dampproofing products.

A:  geterdone, Henry 101 is a foundation coating and is not suited for coating a roof.

A:  Meli, we don’t have any resources for removing the product from the wall. We recommend venting the area, opening doors and windows and getting air flow going to help the product dry/cure.

A:  Mello8361, Henry 101 Non-Fibered Foundation coating contains fairly aggressive solvents and should not be covered with plastic while it cures. The solvents would most likely emulsify the plastic sheeting. Henry 101 will cure in about a week in warm weather but may take longer in cold weather.
