Surface
Preparation:
All surfaces must be sound, dry and free of grease, oil
and dust. A key should be provided on all smooth surfaces
by abrasion.
Because substrates differ a test application is advisable
to determine adhesion.
Concrete:
New:
For best results new concrete should be fully cured for
at least 28 days, have a brush finish and be hand
trowelled (power floating may overwork the concrete).
Clean concrete with an acid wash to manufacturers
specifications and rinse thoroughly with fresh water to
remove residue.
Old:
Use acid wash, agitate solution on surface with a hard
bristled brush, rinse off with fresh water and allow to
dry completely
Sealed Concrete:
Clean surface thoroughly, remove all loose and flaky
patches, abrade surface to give a key and clean surface
again to remove dust.
Should delamination occur on sealed concrete the sealing
compound must be removed by mechanical means i.e.
Shotblasting
In all above cases, wipe over with Xylene prior to
application of ProtectaKote
Please note damp or new concrete can be sealed with
Duraprime. please contact your local stockist or agent
for advice on application.
Aluminium:
Abrade to obtain rough surface, may or may not require
additional primer. Test patch recommended. Use a good
etch primer if needed. Wipe with Xylene prior to
application of ProtectaKote
Steel:
Smooth metal should be cleaned, aggressively abraded and
may require priming to manufacturers specifications.
ProtectaKote adheres well to sound painted metal after
abrading to provide a key, and wiping down with Xylene.
Most rough metal surfaces need not be primed, however, on
applications of extreme wear such as step nosings a
primer is recommended.
Wood:
Surface must be abraded using a medium grade sandpaper or
equivalent. Remove dust before applying ProtectaKote
Note: Applying ProtectaKote to hardwoods containing resin
or natural oils, may cause ProtectaKote to lift. Apply
DURAPRIME or an epoxy primer prior to application of
ProtectaKote. Test patch is advised.
Paint & Varnishes:
Remove all peeling, cracking or chipped paint. Clean
surface and abrade Wipe with Xylene immediately before
applying ProtectaKote.
Rubber:
Clean well using detergent or cleaning solvent. Remove
all surface release agents Rinse well and allow to dry.
Abrade surface, wipe with Xvlene and apply ProtectaKote
Fibreglass:
Good adhesion can be obtained on unweathered gel-coated
glass. Rough fibre side moulded glass and smooth mould
resin-side glass. Surface should be free of release
agent, waxes and other product additives then sanded to
remove gloss giving a rough surface. Wipe with Xylene
prior to application of .ProtectaKote
The Application:
Ensure that surfaces have been prepared properly and
areas not to be coated have been masked off. Remove
masking tape after application of second coat. Add
Accelerator to can; see note Curing Times. Stir can
vigorously before use to obtain a consistent soup like
texture. Your ProtectaKote is now ready to use.
Product should be applied in two (or three) thin coats to
prevent 'mudcracking'
Intercoat time approximately 1 - 4 hours depending upon
ambient conditions (touch dry).
Remove all product from areas not to be coated
immediately with Xylene Once cured ProtectaKote is very
hard to remove. We recommend the use of a suitable
protective clothing i.e. latex gloves and overalls.
Application temperature 0'C to 30'C.
Service application temperature -50 to 140'C
Roller:
This is the easiest form of application and provides a
rougher texture with greater anti-slip characteristics.
Product should be applied with an open foam
stipple/textured roller available from your
local stockist or agent.

Apply the first coat as a thin coat to cover, When tacky
or touch dry (usually within one to four hours) apply the
second coat.
To avoid mud cracking, do not apply ProtectaKote too
thickly. Inter coating times can vary depending on
climatic conditions.
Brush:
Apply product below 25'C
Product should be 'laid' on the surface with a brush.
Do not brush backwards and forwards as with other paints.
Allow approximately 1 - 4 hours between coats or until
first coat is touch dry depending on ambient conditions.
Second or subsequent coats should be applied at right
angles to the previous coat.
Spray:
Screw spray gull nozzle directly onto can and attach
airline Product can be sprayed between 3 and 5 bar
dependant on size of nozzle oil gun and desired finish of
coating
Product should be applied in thin coats to prevent drips
and pools from developing or 'mudcracking' during drying.
Allow approximately 20 minutes to 1 hour between coats or
until first coat is touch dry depending on ambient
conditions.
Curing Time:
Drying time is dependent upon ambient conditions;
however, product should cure within 2 - 4 hours without
the use of accelerator. After this time surface should be
touch dry; however, light traffic should be allowed after
12 hours and product will achieve full cure/strength and
chemical resistance in 4 - 7 days. Under normal
circumstances coating can be put to use after 24 hours.
Accelerator can be used when there is a low atmospheric
temperature or when shorter curing times are required.
This product should be added to the tin of ProtectaKote
just prior to application and should be stirred in well.
Overcoating and Repair:
ProtectaKote can easily be repaired or overcoated. Any
areas of repair should be cut out using a Stanley knife,
the old surface should be well cleaned to remove dirt and
grease and then abraded with a wire brush or sandpaper,
and the edges feathered back using a suitable means of
abrasion. ProtectaKote can then be patch repaired.
Cleaning Solvent:
ProtectaKote is supplied ready for use. Thinning is not
required.
Surface cleaning and equipment cleaning should be carried
out with Xylene. Using White Spirit or alcohol based
lacquer thinners will prevent ProtectaKote from curing
properly and should not be substituted in place of Xylene.
Storage:
12 months shelf life
Cool dry place below 25'C
Precautions:
Never use White Spirit or lacquer thinners to clean
surfaces or equipment or to dilute product
Do no apply to bare metal without an appropriate primer;
see aforementioned notes.
Remove any overspray or splashes immediately. Product is
very difficult to remove once cured/dry.
Once opened use product within three hours or replace lid
and store container upside down if product needs to be
left any longer.
In a wet state product is flammable. Ensure good
ventilation. Solvents are released during spraying,
observe all fire precautions.
Wear breathing mask, goggles, rubber gloves and
protective clothing. Work in a well ventilated
environment.
Protect from moisture and do not expose to temperatures
above 50 Celsius.
