Important Reminder - Prepare the surface correctly
Do it right the first time !
- Ensure that the surface that you are coating is thoroughly clean and bone dry. If you try and take shortcuts the project may fail.
Surfaces that are holding moisture or not completely cleaned (polish and any other contaminants must be removed) may affect the surface and become visible under the coating over the following months after the coating has cured.
- Remember that the coating is crystal clear and any moisture, dirt, polish or contaminants that are trapped under the cured coating will be drawn towards the surface especially during warm weather. This may cause the coating not to adhere properly and visible markings/ clouding will show under the coating. This would mean that you would need to remove the cured coating with xylene and start again. Do not use Xylene to remove the costing from a painted surface as the solvent may remove the paint.
Only apply coating to a scrupulously clean surface.
- Ensure that all polishes and contaminants are scrubbed off the surface. If polishes/cutting compounds have been used at any time previously the surface must be thoroughly cleaned.
- Ensure that the EZPrep cleaning/neutralising solution does NOT dry on the surface when you are cleaning, and that it is thoroughly rinsed away with fresh water.
Only apply coating to a bone dry surface
- Remember that all metals are porous and will hold moisture that may not necessarily be visible to the naked eye; especially in the following circumstances:
- – When the weather is very cold, extremely humid or it has been recently raining
– When the metal is very cold
– When the surface has just been rinsed off after cleaning with EZPrep.
– Even when the surface has been dried off with a microfibre cloth the metal is still likely to be holding moisture.
- Best practice after it has been raining or after rinsing off is to either wait a day after dry weather, or after the sun has been on the metal for some hours before applying the coating.
- If in doubt warm the metal with a blow dryer or use a heat gun on a low setting.
- If the metal has been warmed; as long as you can hold the inside of your wrist comfortably against the metal it will not be too hot to apply the coating.
Why do I need to solvent wipe after cleaning?
- You need to solvent wipe bare metals and anodised metals with pure methylated spirits, acetone or xylene after cleaning and just before applying the coating to the following metals:
- Anodized aluminium joinery (But you do not need to solvent wipe faded powder-coated or painted surfaces)
- Bare aluminium
- Other bare metals such as: copper, brass, bronze, silver, pewter, stainless steel, mild steel, corten and rusted steels
What temperature should the metal surface be?
- The metal surface to be coated is best when at an average temperature – not too cold (otherwise the coating will not dry quickly enough and may sag in places) and not too hot (otherwise the coating will flash off too quickly)
- The coating needs about 20 to 30 minutes to self level. (Ensure that you can hold your wrist comfortably against the metal to see if it is too hot)
Do not overwork the coating !
- Depending on the ambient temperature you have about one minute after the coating has been applied to brush out any drips/sagging. After that you must leave it alone.
- You must not overwork the coating. If you have missed a bit, wait for the coating to dry (an hour) before reapplying to the missed area.
