Overview

Model # HE487623 Store SKU # 1001311103

Henry 487 100% Silicone White Roof Coating is a premium, 100% silicone, moisture-cure coating designed to protect many types of roofs as well reflect the sun's heat and UV rays. While suitable for use in all climates, the 100% silicone chemistry is especially suited for extreme environments, which are exposed to some of the hottest and wettest weather with intense UV exposure. It is specially designed to maintain maximum weatherproofing, and reflectivity of heat and UV rays as it ages. Its moisture-cure chemistry creates a very aggressive chemical bond with the roof, which allows for permanent ponding water resistance, extreme durability, and superior capabilities of sealing and protection.

  1. VOC compliant, solvent free
  1. Wide application temperature range from 2°C to 49°C

Is this product suitable to use on shingle roofs?

Asked by: Raincouver
I would only use it as a temporary fix. It will work very well but will stick out due to colour and not a long term fix.

Is this product suitable for RV trailer rubber roof (EPDM or TPO) ?

My garage roof is made of TPO and it is leaking close to the water exit due to water pond there. I search the internet and found some videos that use Poly Fleece for the reinforcement. Do you think if it is necessary to use it such as BK990-06

Asked by: DIYNewBie
Yes, using BK990-06 with HE487 is recommended for that application.

1. Can this applied to metal roof that is 20 years old? 2. Does this perform as well in extreme cold as in extreme heat? I’m in Canada so months of sub-zero termperatures. 3. How many coats is required for a metal roof? 4. How many sq ft in one pail?

Asked by: Anonymous
1. HE487 can be applied to clean, dry, rust free metal roofing. 2. HE487 has been tested to a service temperature of -40 ͦ C 3. 1 coat is generally all that is required following the recommended coverage rate, however a second coat may be applied for added protection. 4. Approximately 6.5 square meters (70 square feet) per pail per coat. Approximately 9.3 square meters per 5.7 liters per coat (100 square feet per 1.5 gallons per coat). Dry film thickness (DFT) should be a minimum of 22 mils. Coverage varies depending on surface texture and porosity. Roughly 310 square feet per 5 gallon pail.

My garage roof is made of TPO. It was installed 17 years ago. Do you think if it makes senses to apply this coating to extend its life? Thanks.

Asked by: DIYNewBie
