Seal Coating - for ramps and gangways, to bond grit to the surface for skid resistance
- how to coat a steel ramp
Pressure Wash and epoxy solvent clean - surfaces should be mud, dust and grease
Warm if possible in the Winter - using a dry source of heat (not bottled gas)
Apply resin - Epoxy Seal Coat Clear
- 1 mm thick - about 1 litre per square metre - use a medium pile roller, brush
Apply grit - Grit Grade Mixed 1 - 3mm - at
2.5kgs per square metre.

3. Strip the bare
surface or bald spots to clean bare metal.
Clean with our Epoxy
Cleaner, 250cc to ensure
that no oil or grease remains in the metal.
Regrind if necessary to eliminate any solvent cleaner smear film. Wipe over with
a clean White Cloth.
Wipe thoroughly again with the White Cloth - if any dark marks appear on the White
Cloth repeat steps 4 - 6 until the cloth remains perfectly white - this is the
secret of success - any dirt left on, no matter how little, with reduce the resin
bond and lead to bald patches, where the resin has fallen off.
Lay clean cardboard or plastic sheeting around the edges of the plate to catch
aggregate (grit) that falls off during coating, for re-use.
In the Winter, or for cold conditions, heat the metal with dry heat - use electrical
heaters with fans. Avoid gas heating (particularly Propane), because of the water
produced, which can cause condensation on the steel and loss of adhesion. Maintain
background heat until the resin is completely hard. This may take up to 2 days
during cold weather. Lack of heat may also allow condensation to form on the resin
and the aggregate (grit) may then fail to bond properly.
Seal Coat Clear with a smooth
plastic spreader, roller, squeegee or brush, to a depth of 1mm.
Apply clean, dust free Aggregate (grit) to the adhesive so that cover is complete,
with some excess. Pat the aggregate (grit) into the resin very firmly with a clean
wooden or metal object (plastering float, batten, cricket bat), or use a piece
of clean hard plastic material. It is not necessary to apply another coat of resin,
as long as the first coat is thick enough and the aggregate (grit) is fully bedded

for at least 24 hours, subject to temperatures being above 15 degrees C at all
times. Maintain the heating for the whole period.

NOTES - applying resin to Steel Ramps and Gangways
In cold weather you must
keep the metal surfaces above 5 degrees C. Below 5 degrees the resin curing will
slow and curing will be delayed.

and grit adhesion, so screen off the area to prevent draughts and warm up with

ramp or plate MUST NOT BE USED until the coating is really hard. Make a
test piece (of metal or wood) when the resin coating is complete. Coat the test
piece with resin, without grit, and leave next to the gritted area. Test by first
thumb pressure and then with a screwdriver before using the roller. When hard,
the coating still continues to gain strength over several days.
