trying to ensure extra fire protection for e.g. wood / timber, particle
boards and even metal (steel) surfaces a designer or person with
the maintenance responsibility for a building such as a school,
college, hotel or public building will be faced with the need to
meet 2 main goals simultaneously. Firstly the appropriate building
regulations will need to be satisfied to the right rating e.g. BS
476 parts 6 & 7 to Class 1 or Class 0 fire protection rating.
Secondly the internal surfaces of the building will need to achieve
visual / aesthetic consistency with the design themes of the building.
This may require the use of coloured paints and intumescent varnishes.
It is important therefore to find a range with enough choice in
terms of colours and paint types which can provide the right levels
of protection. Here are some examples.
Coating for Timber / Timber Facings and Particle Boards
is an example of a thin white intumescent base coat that can be
applied to new, previously painted surfaces (with the right surface
preparation) and existing materials to provide Class 1 and Class
0 fire protection. In the event if a fire the intumescent element
of the coating reacts to the heat by expanding and thereby insulating
/ protecting the substrate with carbon foam layer. It can be applied
(using a brush or airless spray) to clean dry new and existing surfaces
(where they’ve been rubbed down to provide a key). This base
coat can then have any colour applied in the form of ‘Flameguard
Intumescent Varnish for Timber
is a system that uses 2 products (one on top of the other) to achieve
Class 1 and Class 0 ratings. The system consists of:
1. A thin intumescent base coat – apply 2 coats of this with
a brush roller or hot spray.
2. A clear top coat / overcoat of Intulac Top Coat Varnish.
coatings are damaged by water it needs to be applied to dry surfaces
in conditions with low humidity and condensation levels. N.B. Avoid
using thinners too with intumescent and flame retardant coatings.
Based Flame Retardant Top Coat Paint for Steel
range of paints can check and even prevent fire spread by releasing
a non combustible gas when exposed to fire heat which blankets the
flame itself. Not only can the Flameguard range therefore satisfy
building regulations but there is also a wide choice of paint types
and colours available. For example Eggshell, Undercoat, Gloss (and
Water Based Gloss) and Water Based Acrylic Primer / Undercoat are
available in BS4800, RAL 840HR and NCS 1&2 colour ranges.
