Evo-Stik Intugard Sealant
Intumescent Sealant for Fire Resistant Doors
Evo-Stik Intugard can be used in the following areas:
Tested to BS476 : Part 8 : 1972 to assist fire
doors to achieve half hour or one hour fire
resistance as appropriate.
Easy to apply.
Can be overpainted.
Contains no solvent - safe in use.
Gives a superior smooth finish.
Evo-Stik Intugard is a specially developed paste for placing
by gun in grooves in the edges of doors or door frames.
When the gap between the door and frame is subjected to
heat, Evo-Stik Intugard intumesces so that the gap is
sealed to the passage of hot smoke and flame for a period
consistent with the fire resistance rating of the door.
As Evo-Stik Intugard can be sanded and overpainted the
final appearance of the door is far superior to solid strip
methods of fire resistance.
In fire resistant door set construction. Evo-Stik Intugard
is extruded into grooves, 10 mm wide x 3 mm deep,
cut in the frame or door edge.
One groove for a ‘half hour door’ and two grooves for a
‘one hour door’ is the normal recommendation for fire
resistant doors constructed to satisfactory standard in
other respects.
The intumescing properties have also proved very useful in
connection with the use of Evo-Stik Intugard as a bedding
compound for metallic door furniture.
Upgrading of doors to fire resistant standard.
Ordinary panel doors can be upgraded to a half hour
resistant standard by filling in the panels with plaster
board, bonding 4 mm plywood to both faces and placing
Evo-Stik Intugard in a 10 mm wide x 3 mm deep
continuous groove around the sides and top door edges.
Shelf Life
At least 6 months when stored in a dry place within the
temperature range 5ºC-30ºC.
C20 cartridges in cartons of 12.
Evo-Stik Intugard is a vinyl emulsion
with intumescing agents.
Quantity Guide
Allowing for normal wastage, the contents of
each cartridge is sufficient for approximately
6 m x 10 mm x 3 mm groove.

Assessed to BS476 : Part 8 : 1972 in assemblies, giving half
hour or one hour fire resistance as appropriate.
Precautions in Use
Evo-Stik Intugard does not present any particular hazard during
use. Nevertheless, should skin contact occur, wash thoroughly
with soap and water before the material dries. If the material has
dried, use a hand cleanser. Do not use solvent.
Should the material be swallowed, seek medical advice. In the
event of contact with eyes, irrigate with water and seek medical
Method of Use
Before embarking on any work involving Evo-Stik Intugard, the
section headed ‘Precautions in Use’ and the separate Safety Data
Sheet must be carefully studied by those carrying out the work.
Surface Preparation
Evo-Stik Intugard should be applied to clean, dry freshly cut
grooves in the timber. Metal components, e.g. door furniture,
should be wiped with a clean absorbent cloth to remove any
residual grease or dust.
Store in a dry place within the temperature range 10ºC-30ºC.
Protect from frost.
Spillage and Disposal
Scrape up spilt sealant and reserve for disposal.
Emptied cartridges and waste sealant are not classified as
‘Special Waste’ as defined by the Special Waste Regulations
1996 and may be disposed of as general waste.
Prepare 10 mm wide x 3 mm deep grooves in the frame
or edge of the door.
Ensure that Evo-Stik Intugard has been stored within the
temperature range stated, so that it will be easy to extrude
and apply.
Cut the cartridge nozzle at the point required to provide a
suitable diameter of bead of paste. Cut off the dome at the
top of the cartridge without damaging the thread and screw
the nozzle onto it.
Fit the cartridge into the caulking gun and extrude the sealant
into the groove. Ensure that Evo-Stik Intugard is forced into the
groove so that the surfaces are completely wetted and no voids
or gaps are left.
An excess of Evo-Stik Intugard should be left proud of the timber
surface, about 2-3 mm, to allow for shrinkage on drying.
Produce the correct shape by forcing the bead into the groove
with a profiled scraper.
When dry, (after approx. 24 hours) sand the surface of Evo-Stik
Intugard flush with the timber. Any small defects can be made
good by brush applying Evo-Stik Intugard to which some water
has been added. This can normally be sanded after about
90 minutes drying.
The filled groove and door edge may be painted with a two coat
alkyd decorative system or varnished with a clear alkyd-based
varnish without impairing the performance of the seal in a fire
