Directions of using Fire Block

Fire Block is very easy to use. Just spray on the item or surface being treated. Make sure the item gets completely wet. In bulk applications, you may also dip the items and allow to drip dry. In all applications, allow it to completely penetrate the item or surface. Allow material to dry completely. If you are using it to fire retard clothing and other fabrics, and plan to wash these items in the future, it is recommended that it be reapplied after the third washing, as some of the product’s effectiveness will be diminished due to washing. When mixing with latex paint, mix equal parts with the paint. An extra coat of paint may be necessary, because it will thin the paint.
