Flame Seal Wood Seal-A Fire RetardantFlame Seal Wood Seal-A Fire Retardant is an application ready, water-based, Class A fire retardant designed for treatment of raw woodFlame Seal Wood Seal-A is a mix of proprietary ingredients, which forms a slight swelling foam layer and carbon char when the treated wood is exposed to fire.  Once the carbon char is formed there will be minimal flame increase, smoke evolution or afterglow.  The retardant is designed for interior use onlyHowever, Flame Seal Wood Seal- A can be used in exterior applications if top coated with an approved non-flammable paint or coating.

Uses: Flame Seal Wood Seal-A is designed for use on unpainted / unsealed wood, paper or other cellulose type materials.

  • Water-based, low odor, non-toxic, non-hazardous and contains no halogens.
  • Applied by brush, roller, spray and submersion methods to unpainted / untreated wood, paper, or other cellulose products.
  • The surface must be able to absorb the water based fire retardantto provide fire protection.
  • Interior walls do not require a stain or top coat.
  • Exterior surfaces should be stained with a compatible, non-flammable stain or top coat after treatment with the retardant.
  • The official ratings given for this product was from testing on Douglas Fir, which is considered the standard for testing. Tested on Douglas Fir in the ASTM E84-05 (Steiner Tunnel) flame spread test.
  • Slows flame spread and prevents fire from propagating along the treated surface, which also reduces smoke production.
  • Available in 1 gallon – 55 gallon drums

 

Coverage

Coverage rate should be 150 – 350 square feet per gallon as determined by porosity of wood and on wood that has no Mill Glaze.

Fire Listed Ratings

Many factors contribute to the flammability and treatability of different wood varieties such as oil and resin content, moisture content, the ability to absorb these water-based products, etc. Therefore, Flame Seal Wood Seal- A will not achieve the fire listed ratings on all woods. As such, some woods are much harder to fire treat than others.  The official ratings given for these products were from testing on Douglas Fir, which is considered the standard for testing.  It absorbs liquid fairly well and has an untreated Flame Spread of 90 to 105Comparison charts of flame spread rating for most wood types are available on the internet.  Any flame spread ratings to be met or claimed must be determined by the customer.

Warranties

  • Wood Seal-A’s Class A fire rating was achieved on Douglas FirOther woods of a similar, or lesser inherent fire spread rating, and penetrability, when properly treated should meet Class A fire testing requirements.
  • There are no other warranties either expressed or implied since Flame Seal Products, Inc. cannot control the actual application of the products.  Users must determine usability and suitability for their particular requirements, as well as compatibility with the exact materials to be treated or coatedException:  An Expanded Warranty is available for work performed by Certified Applicators.

 

Non-Code Adequate Treatment?

To test for general adequate treatment, apply a flame or torch to a sample of fire retarded material.  If the flame does not spread rapidly away from the heat source and goes out soon after the heat source is removed, then your material is probably sufficiently treated.  If you are trying to meet code, check with your local fire marshal as to what is acceptable.  You may have to pass third party testing.

 

Testimonial

 From a Flame Seal customer in Tujunga, CA,  site of the famous Station Forest Fire in 2009.

 

I have been wanting to tell you about the successful use of your Flame Seal fire retardant on our forest cabin. In May of 2009 we refinished our deck, and since our home is in a fire prone area inside a National Forest, we wanted to use a fire retardant. We selected your Flame Seal and treated the wood on the deck with a generous amount of it before we put on the top coat.

It turns out this was a lucky, or perhaps prescient, move on our part. Four months later, on August 29, 2009, the Station Fire consumed more than 50 of our neighbors’ homes. This fire eventually became the largest blaze in Los Angeles County history. While we watched the devastation we didn’t have much hope for our cabin, but two days after the fire ran through, we were allowed to return and see to our amazement that our house was still standing! There were a thousand tiny burn marks all over the surface of the deck where embers landed, and the back of the house, which was also treated with Flame Seal, had bubbling paint and a warped plastic thermometer, but none of the ignition points sustained burning. We were so pleased; we bought another five gallons to seal the entire surface of the house, which had to be repainted after the fire.

This stuff works! We will tell all of our neighbors who rebuild and who still live in the area about your product.
