Taking a few quick steps to make your own fireproof paint can save you a lot of money. Water-based paints and stains can become more fire-safe when mixed with a fire-retardant additive. In general, these additives do not affect the texture, sheen or color of the paint and will give you greater peace of mind. It is important to note that your paint mixture will help to slow the spread of flames but will not be completely fireproof.
Determine how much paint you need. In general, one gallon will cover 350 square feet. Choose a flat latex plaint in the color of your choice.
Purchase a fire-retardant paint additive from your local home-improvement store. Each gallon of paint will require one 6-oz. package to achieve a class B rating and two 6-oz. packages to achieve a class A rating.
Mix in the appropriate amount of fire-retardant additive to the paint. Stir the paint thoroughly, or take it to your local home improvement store to have the can of paint shaken.
Class A has a flame spread rating of 0-25. Class B has a flame spread rating of 26-75.
Before starting your project, familiarize yourself with fire safety and flame-spread ratings.
