Firewall Flame Retardant Paint
Home - Firewall Flame Retardant Paint
What is passive fire protection: The fundamental purpose of passive fire protection is to prevent the spread of smoke and fire and thus prevent / reduce the amount of damage to the structure or substrate in case of a fire.
How does Firewall work: Firewall coatings provide an appearance similar to that of a paint finish. At ambient temperatures, they remain stable. However, in a fire situation, the increase in temperature causes a chemical reaction and coating expands to many times its original thickness (upto over 25 to 40 times). This provides an insulating foam-like coating or "char' which protects the substrate.
Where it can be used: Firewall can be used where a paint is applied. There are separate variants of Firewall for (1) wood including walls / other surfaces / concrete, (2) steel and (3) Cable. (Please note that paint in an open area specially exposed to rains may reduce the effectiveness if surface is washed off.)
Application: Firewall is best for base-coat finish however since it comes in white, any color can be mixed to convert it into final top coat as well. It is 'ready to use’, would require minimum two undiluted coats (second coat after first coat has dried) and will achieve a fire rating of 30 to 60 minutes for heat up to 1000°C. It is best applied with Brush however can also be applied with airless spray / roller. Stir before each pouring and intermittently during application. IF LEFT UNUSED FOR PROLONGED PERIOD, STIR WELL AT LEAST ONCE A WEEK TO AVOID SETTLING OF INGREDIENTS. (Recommended use of electric drill attaching a long rod with ‘stirring’ hook / tip at the other end. If gone too thick, add 200ml turpentine, stir. Repeat till you get required consistency)
How long does Firewall last: Lasts as long as the paint. (Paint in an open area specially exposed to rains may reduce the effectiveness if surface is washed off).
Note: The effectiveness of an intumescent fire resistive coating depends on the ‘coating thickness i.e. DFT (Dry Finish Thickness). Higher the applied thickness (DFT), higher resistance to withstand a fire of a certain temperature and duration. Recent improvement in technology has made it possible to get same desired results with comparatively thinner DFT.
The amount by which Firewall coatings retard a particular fire will depend, among other things, on (1) the amount of Firewall coating applied, (ii) the conditions of the other elements of the assembly and (iii) the condition of the fire itself. Ensure paint is not cracked, chipped or peeling. Firewall coatings will only contribute to slowing fire spread for the area where applied and will not by themselves prevent a fire from starting or continuing.
