Flex Seal Q & A

Q: What is Flex Seal?

A: Flex Seal is an advanced coating engineered to stop fiberglass emissions and to prevent the ingress of particulates into fiberglass and other porous materials. Flex Seal is also used for interior walls, insulative pipe coatings, and other materials. Fiberglass is a known carcinogen, and it's emission is undesirable.

Q: Our county requires stict adherence to Fire Codes. Will Flex Seal meet our State and local Fire Code requirements?

A: Flex Seal exceeds all fire code requirements, and is superior to a Class One fire code. Flex Seal is ASTM E-84 Certified at a zero (0) Flame Spread.

Q: Where can I use Flex Seal?

A: Flex Seal is recommended for use on interior walls, fiberglass and rubber insulation on pipes and other surfaces, insulation under wall board, and interior metal surfaces.

Q: I have insulated pipe where I have fiberglass emission problems. Can Flex Seal be of use to me in this area?

A: Yes. Flex Seal may be applied to pipe surfaces to prevent fiberglass emissions.

Q: Is Flex Seal flammable prior to use?

A: No. Flex Seal is a water-based, non-flammable liquid.

Q: What equipment is required to apply Flex Seal?

A: Typically, an airless sprayer is used to apply BioFlex. The film thickness should be approximately 15 to 25 mils depending on the surface applied to. Porous surfaces may require higher thickness.

Q: What about freezing?

A: Freezing represents an important issue to the consumer. Most products now available have to be protected from freeezing, and require special handling and stroage during cold weather, otherwise the product turns into an unusable "cottage-cheese". Flex Seal does not require special handling. It passes five freeze-thaw tests with no reduction in performance. So, you can stop worrying about losing your product due to accidental freezing and use Flex Seal anytime you want to, with no special shipping or handling.

Q: Do I need to be concerned with strong odors? My current coating odor limits me as to when I can get my crew in to work.

A: You do not need to be concerned with odor with Flex Seal. Low odor is one of it's features. Flex Seal has an actual indepently certified VOC value of 26.84 per the ASTM D-3960 method. This is not a calculated VOC, but an actual certified value.

Q: I have to mix my current coating prior to my using it. At times I also have to strain it to remove small lumps and other inconsistencies. How does Flex Seal compare?

A: Flex Seal is manufactured to tightly controlled quality standards. No mixing is required, and no straining is required prior to use.

Q: How is Flex Seal applied?

A: An airless sprayer is recommended of at least 2,000 psi. Brands recommended include Binks, Wagner SprayTech, Graco or similar.

Q: I want to use a low VOC paint. How does Flex Seal relate to industry and governmental standards?

A: Flex Seal exceeds EPA standards for coatings. EPA regulations call for no more than 250 g/l VOCs, and suggests a voluntary standard not to exceed 50 g/l for interior coatings. A certified independent lab testing Flex Seal reported a VOC of 26.84 g/l, close to one-half of the EPA's voluntary limit.
