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 30 to 50 times). This provides an insulating foam-like coating or "char" which protects the substrate.

Where it can be used: Firewall Can be used anywhere i.e. walls, concrete, wood, steel etc. (wherever a paint is normally applied). (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 finish 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 upto 1000°C. It is best applied with Brush. Stir before each pouring and intermittently during application.

Approx. coverage:  While exact coverage will vary with method, surface finish, condition of application etc., the prepared mixture of one packet of additive with one Litre of paint with required thinner will cover approx. 100 to 110 sft. in first coat and 110 to 120 sft. in second coat. 

Drying Time: Three hours. (ambient temperature)

How long does it 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) and requirement typically starts from 200 microns  which you should normally get in two undiluted coats as above. However higher the applied thickness (DFT), higher resistance to withstand a fire of a certain temperature and duration.  An abnormally high resistance required would need proportionate higher DFT taking into account kind of substrate and thus will need calculation from specialists.)

Variants / packing available: Oil / solvent based (enamel) – in base white color in four litres and 20 litres pack each. (minimum quantity 50 Litres). For small quantities ‘Shield FR Additive’ is available.

The amount by which Firewall coatings retard a particular fire will depend, among other things, on (i) the amount of Firewall coating applied, (ii) the conditions of the other elements of the assembly and (iii) the conditions of the fire itself. It is the sole responsibility of the applicator to ensure that Firewall coatings are applied in accordance with the application directions, 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. .

ADDITIONAL  INFORMATION FOR THOSE WHO ARE USING FR PAINT ‘ADDITIVE’

How to convert normal paint into Firewall
1. Pour Enamel Paint, Additive (one packet for one Litre of Enamel Paint), Thinner (125 ml for one litre of Enamel paint) into a bucket.
2. Stir manually till it becomes a mixture
3. Mix with blender (part of kit to be attached with hand drill – available with all electricians, carpenters, plumbers etc.) for at least 5 minutes or till  the mixture is homogenous

4. Paint is ready for application.

Note: Powder tends to settle down – stir before each pouring and intermittently during application.

Usage of mixture: within 24 hours for best results.  For more than 24 hours, add a little bit of thinner if mixture has become thicker.  Recommended to prepare only required amount of mixture and always keep it tightly covered.
