Burn Barrier 149:

Flame Control No. 149 is a highly flexible, weather resistant, intumescent fire retardant paint. When attacked by fire or high heat, the coating intumesces (puffs up), forming a thick, dense foam fire barrier. This foam barrier retards heat penetration and checks the spread of flame.

Burn Barrier 149 recommended uses:

This product was primarily designed for use on wood or metal crating and containers used for the storage, transportation, and disposal of highly hazardous substances, such as radioactive materials, nuclear waste,
poisonous gas cylinders, and other hazardous items requiring maximum fire protection.

Surface preparation should be carried out according to good painting practices. All dirt, grease, oil, wax, rust, and other foreign matter must be removed.

New Surfaces:

New wood, fiberboard, and other surfaces having uneven or excessive porosity, should be sealed with an acrylic sealer or equivalent and allowed to dry a minimum of 6 hours, before applying No. 149. New metal
surfaces must be primed. Apply Flame Control No. 3004-A Universal Primer or Flame Control No. 3005-A
Two Component Epoxy Primer. Allow to dry 16 hours or until hard, before applying No. 149.

Previously Painted Surfaces:

No. 149 may be applied directly to most existing paints that are tightly adherent, and in good condition. However, we recommend spot testing for lifting. If lifting occurs, remove old coating and treat as new surface.
All glossy surfaces should be dulled with sandpaper. Spot prime where necessary with appropriate Flame Control primers as shown above, before applying No. 149.


Flame Control No. 149 is ready to use. It can be applied by brush, roller or conventional heavy-duty spray equipment. Stir thoroughly and apply, using a full-bodied coat. If thinning is required, use only No. 149 Special

USE ONLY WITH ADEQUATE VENTILATION. Do not breathe vapors or spray mist. Ensure fresh air entry during application and drying. If you experience eye watering, headache or dizziness or if air monitoring demonstrates vapor/mist levels are above applicable limits, wear an appropriate, properly fitted respirator (NIOSH/MSHA approved) during and after application. Follow respirator manufacturer’s directions for respirator use. Close container after each use. Avoid contact with eyes, skin and clothing. Wash thoroughly after handling.

FIRST AID: If you experience difficulty in breathing, leave the area to obtain fresh air.
