BROSTEEL - Thin Film Intumescent Coating (Water Based Emulsion)
The INTUSTEEL WB System
FLAMEGUARD - Solvent Based Top Coat

BROSTEEL

Brosteel is a smooth, thin film Intumescent Coating for the Fire Protection of Structural Steel and other substrates.

Due to its formulation, Brosteel does not require any specialist application skills and can be applied by brush or airless spray by any competent contractor.

Whilst Brosteel provides the base coat fire protection, the system is completed by overcoating with Bollom Flameguard, providing a colourful, decorative finish and protecting the Intumescent Coating from accidental damage.

Brosteel’s quick drying formulation ensures faster application and contract completion. It can be applied even in low temperatures, 5ºC and above, which is a major advantage.

Conventional Intumescent Coatings may require much higher drying temperatures. Brosteel is highly economical and cost effective when compared to other Fire Protective systems. It can be applied at any stage during completion of the building, with minimum interference to other trades.

The Brosteel system saves valuable time and cost on site.

• Faster drying times.
• No specialist application skills required.
• Easy to apply by brush or airless spray.
• Available Ex-stock.

Ensure that previously primed surfaces are clean from grease. Unprimed steelwork should be cleaned to BS7079: Part1 SA21/2, dry and free from oil and grease. Prime with Bollom Zinc Phosphate primer or a similar good quality primer.

Galvanised surfaces should be de-greased and primed with Bollom 2 Pack Etch Primer or similar good quality primer.

Brosteel should be applied only where the building temperature is 5ºC or above, and must be maintained during the application and drying periods.

The relative humidity should be below 75% throughout the application and drying periods. Brosteel is unsuitable for external structural steelwork. Its unique and easy to apply formulation was developed for application to internal steel structures which are weather protected.

Brosteel should only be applied when the metal temperature is 3ºC or more, above dew point.

The Brosteel system can be applied by brush or airless spray.All application equipment should be cleaned immediately after use with the appropriate cleaner.

Bollom’s wet film thickness gauge should be used during each applied coat to be sure the correct loadings have been applied at the specified rate.

Spray Equipment – We recommend the Graco Ultra Max 1095 airless unit, or equivalent.

For technical advice on spraying techniques, and for sales and hire rates for spray equipment, please contact Bollom Spray Division on (020) 8658 2299.

Apply Brosteel to a total loading sufficient to achieve half hour/one hour fire protection to structural steelwork, previously primed with Bollom primer, or a similarly good quality primer, in good condition.

After an application of Brosteel, apply a single coat of Flameguard overcoat.Application to be carried out with full recommendation of Bollom Fire Protection.

THE INTUSTEEL WB SYSTEM - DECORATIVE INTUMESCENT PROTECTION FOR STRUCTURAL STEEL

Intusteel WB provides a cost effective solution for the fire protection of structural steel. Due to the low film thickness required to achieve the desired fire rating, contractors and applicators require less wet material and fewer coats.This results in a faster and cheaper solution to your fire protection needs.

The Intusteel WB system saves time and money on site:-

• Ease of application.
• Low film thickness.
• Reduction in application time.
• Water based formulation.
• Technical support.
• Calculation service.

Intusteel WB can be applied over previously primed surfaces that have been suitably prepared. Remove grease, oil, paint coatings and any other contaminates. Surfaces should be blast cleaned to a minimum standard of cleanliness SA21/2 as defined in BS7079 Part 1: 1989 to a surface profile not exceeding 100 microns.

A suitable approved primer must be applied within 4 hours of blasting or before the surface has re-rusted.

Intusteel WB should be applied only where the building temperature is 5ºC or above, and the relative humidity is below 75% throughout the application and drying periods. Intusteel WB must only be applied when the metal temperature is 3ºC or more, above dew point.

Intusteel WB is unsuitable for external structural steelwork. It should be used on internal steel structures that are weather protected.

Intusteel WB can be applied by airless spray, brush or roller.

Airless spray is the recommended method of application. It is particularly cost effective, as one coat of Intusteel WB will provide the required fire resistance for many sections.

Airless Spray Application
Intusteel WB may be applied up to a maximum wet loading of 1000 microns (1 litre / m2) in a single coat. During application it is essential to measure the wet film thickness frequently to ensure the required thickness is achieved. Where the final surface finish is required to be of a high standard,multiple coats should be applied to achieve the specified dry film thickness.

Brush Application
Brush or roller application will normally require more coats. The maximum wet loading per coat is 500 microns (1/2 litre / m2).

Application Control
Wet film thickness can be measured using a wet film thickness gauge.To calculate the required number of spray, brush or roller applications, consult the film thickness data chart. Check dry film thickness before applying Top Seal.

Intusteel WB Top Seal
The Intusteel WB system is completed by overcoating with Flameguard Top Seal providing a highly decorative colourful finish and protecting the intumescent coating from accidental damage.

A comprehensive range of flame retardant paints which enables the designer to maintain the overalldecorative theme yet satisfy today’s building regulations for fire protection.

Flameguard paints are formulated to be as easy to use as conventional paints providing a high quality durable finish.

Conventional paint systems, when subjected to high temperatures, will break down and encourage fire spread. However, when the substrate is treated with Flameguard paints, fire spread is severely checked or even prevented.

Flameguard Decorative Finishes
A full range of finishes - Gloss and Eggshell oil based paints, Matt and Vinyl Sheen Emulsion,Water Based Acrylic Gloss and Eggshell paints.

Flameguard Colour Range
Available in the full BS4800, RAL 840HR and NCS 1&2 colour range in most finishes.

Combustible Surfaces
Flameguard will upgrade, (when used with our Broflame Intumescent Emulsion) combustible surfaces to provide Class 1 and Class 0 fire ratings.

Previously Painted Surfaces
Flameguard paints can provide Class 1 and Class 0 ratings on previously painted
non-combustible surfaces and, if used in conjunction with Broflame Intumescent Emulsion, can upgrade previously painted combustible surfaces to Class 1 and Class 0.

Flameguard paints are formulated so that in the presence of heat a non combustible gas is evolved which effectively blankets the flame, preventing or severely limiting flame spread.

Flameguard Matt Emulsion
Flameguard Matt Emulsion is quickly and easily applied. Its fast drying formulation and alkali resistant coloured pigments make it particularly suitable for internal wall surfaces and ceilings where a tough, washable hard wearing finish is essential.

Flameguard Vinyl Sheen Emulsion
Flameguard Vinyl Sheen Emulsion provides a high quality decorative finish which has a luxurious silk sheen. Based on a special vinyl resin it is particularly suitable for internal wall surfaces and ceilings where a tough, washable hard wearing finish is essential.

Flameguard Eggshell
Flameguard Eggshell provides a high class, hard wearing satin finish which is washable and highly resistant to condensation and humidity. It is particularly suitable for interior use on wall surfaces in public buildings, factories and schools.

Flameguard Undercoat
Flameguard Undercoat is a high quality Undercoat specially formulated for use under Flameguard Gloss and Eggshell. It has excellent obliteration and maximum holdup as well as good flow and is easy to apply.

Flameguard Gloss
An exceptionally hard wearing decorative protective finish. Flameguard Gloss is formulated for maximum flow, film build and colour retention, which dries to a full brilliant gloss finish. It is suitable for exterior as well as interior applications.

Flameguard Water Based Acrylic Primer/Undercoat
