The surface must be clean, dry and free of oil, grease, salt and other surface contamination including any sanding, blasting or other preparation residues before applying PID 60 Marine.
Metal Surfaces excl. Galvanised, Zinc and Aluminium:
Prior to blasting or manually preparing the surface, all salt contamination should be removed using freshwater and the surface dried. All oils, grease etc. must be thoroughly removed using a suitable cleaning solvent e.g. Acetone.
Deposits firmly adhered to the surface should first be removed by scraping and then cleaned using the solvent. Remove all traces of mill scale, rust, rust scale and other foreign matter by blast cleaning to SIS-Sa2½ or at the least manually to SIS-St3 by grinding (P24-P36) or sanding (40-120 grit).
Remove all blast and manual preparation residue by vacuum cleaner, air blower or a stiff clean brush. For difficult areas, the removal of rust by chemical means may be possible with undiluted Owayell.
Thoroughly clean surface using Owaclean or a suitable solvent e.g. Acetone. Blast surface using a suitable medium or sand with 24-120 grit abrasive compatible with Aluminium. Remove all blast and manual preparation residue by vacuum cleaner, air blower or a stiff clean brush. For difficult areas pickle the surface using diluted Owayell.
Thoroughly clean surface using Owaclean or a suitable solvent e.g. Acetone. Pickle the surface using diluted Owayell.
Clean surface with Owaclean or hot soapy water, rinse thoroughly and allow to dry. Abrade with 180-220 grit sanding discs. Remove all sanding residue by vacuum cleaner, stiff clean brush, tack cloth or a cloth soaked in a fast flashing solvent e.g. Methylated Spirits (Not White Spirits).
Previously Painted Surfaces:
Checking the existing finish for adhesion by using the Cross Hatch test method. If the existing finish has poorly adhered it must be completely and thoroughly removed by blast cleaning to SIS-Sa2½ or at the least manually to SIS-St3. If the coating is well adhered proceed as follows: Thoroughly clean and sand/blast surface to form a good key, feather in any sharp edges and any bare areas of metal to be manually prepared to at least SIS-St3.
Note: It is imperative that prepared bare metal surfaces are coated with PID 60 Marine within 8 hours.
Stir well before and during use.
Apply an even, single coat at the recommended wet film thickness.
Allow to dry.
If required a second coat may be applied.
PID 60 Marine may be diluted up to 30% with White Spirits for spray application (NOT Airless or Airmix).
If a perfectly smooth surface is required PID 60 Marine may be sand when 100% cured before applying the finish.
If the over-coating time of PID 60 Marine exceeds 5 days, clean surface with a suitable solvent e.g. Acetone. Sand with 220-230 grit abrasive and dust off.
Wipe the surface with a cloth soaked in Methylated Spirits or a tack cloth to remove any remaining sanding residue.
Stir well before and during use. Apply an even, single coat at the recommended wet film thickness. Allow to dry. If required a second coat may be applied.
Things to Remember
Cover everything you do not wish to paint, especially when applying by roller or spray.
Apply between 5°C (41°F) and 35°C (95°F). Substrate temperature should be between 5°C (41°F) and 35°C (95°F).
Ensure substrate is at least 3°C above the dew point.
Do not apply in direct sunlight or to hot surfaces (35°C+ (95°F+).
Drying time is affected by 3 factors: Temperature ideally understood to be between 5°C (41°F) and 35°C (95°F).
Relative humidity, ideally between 50% and 60%.
Good ventilation in the working area.
If one of the above conditions is not met the drying time of PID 60 Marine should be extended to avoid the risk of a reaction with the finish coat.
Use appropriate protective clothing especially when spraying e.g. gloves, goggles, mask etc.
