Intumescent Paint is used in many types of construction assemblies because it is cheaper that traditional building applications. There are Four Types of Construction That Use FlameOFF Products.
New construction has many uses for an Intumescent Coating.
FlameOFF products are constructed in such a way as to achieve a code-determined fire-resistance rating, thus forming part of a fire compartment is passive fire protection.
There are many unplanned mishaps in the construction industry and rebuild is usually not an option.
Adherence to fire safety codes is more difficult for historic properties than for new construction.
To allow for proper drying of the fire protective coating. Ventilation will speed up the drying time. If no ventilation is available, a small fan can be placed in the area to circulate the air flow.
Do not exceed a relative humidity of 95%. High humidity levels will increase the drying times and can also affect adhesion and can cause blistering in the coating.
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.
It is recommend for a faster and smoother application the fire coating should be sprayed with a airless paint sprayer.
To insure proper adhesion of the intumescent coating, the substrates need to be free from dirt, oil, grease, and any other substance that can effect the adhesion of the intumescent coating.
The intumescent coating must not be diluted. It is recommended that the coating be mixed with a paddle mixer for 1 to 3 minutes.
Do not exceed wet film thickness (WFT) of 0.045” (1.16mm) by spray application, or (WFT) of 0.020 (0.5mm) by brush application, per coat. Wet film thickness are dependent upon relative humidity and airflow.
Typical spray distance from substrate to end of spray gun is between 24” and 36”. This spray distance will insure a smooth spray application of the intumescent coating.
It is recommend that a drying time between coats is 8 hours. Applying coats prior to 8 hours can cause blistering of the intumescent coating. As a rule of thumb, try to press your finger nail in the coating. If you can make an indention, the coating is not dry. The intumescent coating should not be anle to be indented with your fingernail if the coating is dry.

A top coat is not required for conditioned interior space unless the top coating is for a desired color. For a unconditioned space where there is indirect weather conditions. A top coat is recommended. Contact FlameOFF Coatings, Inc. for a list of tested approved top coats. A indirect weather condition is considered a high humidity area, freeze/thaw area such as a attic, craw space, or parking deck.
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.
Most paints for general consumer use cover about 400 square feet per gallon. This amount is maximum coverage on a well prepared surface with no heavy texture or other abnormalities. If you are facing a stucco or other kind of unfamiliar surface, and it's a big job, the best way to calculate the coverage of the paint is to do a test.

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.
