At FlameOFF Coatings, Inc., we still believe in personally answering the phone. In fact, when you call our toll-free number, you'll always speak directly to a live person who is knowledgeable about our products and processes. FlameOFF Coatings, Inc. personnel have all witnessed fire tests and understand building and NFPA codes and standards. We work with building officials and fire marshals nearly every day, answering questions and providing test reports.
No. Since their invention, FlameOFF Coatings, Inc. fire-retardant and intumescent products have never been toxic. While formaldehyde might be considered non-toxic at very low levels, it remains a known carcinogen. At FlameOFF Coatings, Inc., we strive to develop water based products that meet or exceed LEED requirements.
No. Different materials require different products. For example, would you apply a latex-based paint to fabric? Our expertise allows us to always recommend the right FlameOFF Coatings, Inc. product for your specific needs.
In most cases, you can fire retard the material yourself, as long as you closely follow the application instructions. Because FlameOFF Coatings, Inc. products are non-toxic and water based, you can use a garden sprayer or airless paint sprayer to apply our fire retardant fabric spray until the surface is wet to the touch. In order to verify the product was applied correctly, you can perform the NFPA 705 field test after application. This test utilizes a kitchen match, kitchen tongs, and a small swatch of the fabric to verify sufficient saturation.

Intumescent paint is used in many types of construction including new construction, retrofit and defective building construction, and historic restoration/renovation construction. Specifically, our intumescent paint can fire rate interior structural steel, gypsum, and wood.

Ventilation

Ventilation is recommended to allow the intumescent coating to properly dry/cure. If no ventilation is available, a small fan can be placed in the area to circulate the air flow.

Humidity

Do not exceed a relative humidity of 95%. High humidity levels will increase drying time, affect adhesion and can cause blistering in the coating.

Brush Application

The fire coating can be brushed with a high-grade latex paint brush. It is recommended that the coating is brushed in smooth even strokes.

Spray Application

For a faster and smoother application it is recommended that applicators use an airless paint sprayer.

Cleaning

To ensure proper adhesion of the intumescent coating, the substrates need to be free from dirt, oil, grease, and any other substance that can affect the adhesion of the intumescent coating.

Dilution

The intumescent coating must not be diluted. It is recommended that the coating be mixed with a paddle mixer for 1 to 3 minutes.

Wet Film Thickness

Do not exceed WFT of 45 Mils (1.16mm) by spray application, or WFT of 15 Mils (0.38mm) by brush application, per coat. WFT is dependent upon relative humidity and airflow.

Spray Distance

Typical spray distance from substrate to end of spray gun is between 24” and 36”. This spray distance will ensure a smooth spray application of the intumescent coating.

Between Spray Coats

The recommended drying time between coats is 8 hours. Applying coats prior to 8 hours can cause blistering of the intumescent coating. The surface must dry and harden so you are not able to press your finger nail into the coating and create an impression. If you can make an impression then the coating is not dry.

Top Coating Requirements

A top coat is not required for conditioned interior space unless it is for a desired color. Once the product is cured, it may be top coated with latex, acrylic, or oil based paint.

Repair

The damaged area should be cleaned and dried. The intumescent fire coating can be applied directly to the damaged area with the proper mil thickness to repair the area.

Trying to determine paint coverage with an intumescent paint can be tricky. Intumescent paint coverage rates are based upon Dry Film Thickness (DFT). DFT varies depending on the type of substrate and, in the case of structural steel, the specific steel members being coated. Please contact a FlameOFF Representative to figure DFT and coverage rates for your particular project.

Tip plugging is caused by solids in the paint that are too large to pass through the tip orifice. Diluting or thinning paint does not reduce the size of the solids. Here is a list of things you can try in order to avoid tip plugging.

  1. Flush the sprayer.
  2. Clean the rock catcher filter.
  3. Remover the gun filter.
  4. Re-prime the system.
  5. Use a larger spray tip if the machine will support it and the application will permit.
