All surfaces to be coated should be clean, dry and free from contamination. Prior to
paint application all surfaces should be assessed and treated in accordance with
ISO 8504:1992.
Where necessary, remove weld spatter, and where required smooth weld seams and sharp
Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.
Abrasive Blast Cleaning
Abrasive blast clean to Sa2 (ISO 8501-1:1988) or SSPC-SP6. If oxidation has occurred
between blasting and application of Interplate 11, the surface should be reblasted to the
specified visual standard.
Surface defects revealed by the blast cleaning process, should be ground, filled, or
treated in the appropriate manner.
The blast profile achieved should have an angular configuration. Blasting media should
be steel grit of a nominal size of 0-6-1.0 mm (24-40 thou) or a mixture with steel shot of a
nominal size of 0.6-1.4 mm (24-56 thou).
This product is NOT recommended over hand prepared steel.
Mixing Interplate 11 is supplied in 2 parts, a liquid Binder base
component (Part A ) and a Paste component (Part B). The
Binder (Part A) should be slowly added to the Paste (Part B) whilst
stirring with a mechanical agitator. DO NOT ADD PASTE TO
LIQUID. Material should be sieved prior to application and
should be constantly agitated in the pot during spraying. Once the
unit has been mixed it should be used within the working pot life.
This is a low viscosity material and agitation is required during
application to ensure homogenity is maintained.

Brush Suitable - Touch up and small areas only
Roller Suitable - Touch up and small areas only
Thinner International GTA803 Do not thin more than allowed by local
environmental legislation.
Cleaner International GTA803
Work Stoppages Do not allow material to remain in hoses, gun or spray equipment.
Thoroughly flush all equipment with International GTA803. Once
units of paint have been mixed they should not be resealed and it
is advised that after prolonged stoppages work recommences with
freshly mixed units.
Clean Up Clean all equipment immediately after use with International
GTA803. It is good working practice to periodically flush out spray
equipment during the course of the working day. Frequency of
cleaning will depend upon amount sprayed, temperature, relative
humidity and elapsed time, including any delays.
All surplus materials and empty containers should be disposed of
in accordance with appropriate regional regulations/legislation.
Satisfactory welding properties will only be obtained by strict control of application to
the recommended film thickness. Over-application of Interplate 11 will result in
increased levels of weld fume on cutting and welding, and will also increase the porosity
of the welds.
Interplate 11 is designed for application by automatic plant, if small areas are to be hand
sprayed, take care to avoid dry spray and over-application.
Note, this product dries too quickly to enable accurate wet film thickness measurements.
Failure to obtain an even film and coverage of blast profile will result in rapid rash
rusting on exposure to weathering.
The drying times quoted are for the recommended dry film thicknesses at the stated
temperatures when using automated process. Failure to adhere to these parameters can
result in damage to equipment, rollers and disruption of the coated surface due to
handling damage on stacking. Best results are obtained by using steel preheated to a
temperature of 40°C (104°F).
Thicker films of Interplate 11 will provide longer periods of corrosion resistance, but will
compromise welding, cutting and handling properties. In most environments to obtain 6-
9 months protection 25 microns (1 mil) is a recommended dry film thickness.
Satisfactory curing for overcoating within 24 hours will not be achieved at relative
humidities less than 50%. At relative humidities below 50%, curing will be severely
retarded and humidity may need to be increased by steam or water spraying.
Interplate 11 is compatible with both sacrificial and impressed current cathodic
Prior to overcoating, Interplate 11 must be clean, dry and free from both soluble salts
and excessive zinc corrosion products.
