I have my refurbished bulkhead which has come t-washed and primed ready for my top coat. But after they put on the primer, they have put on a 'splatter coat'. I asked what this was for and was told it was to aid as a visual guide when rubbing down...

I have tried to look online to find out exactly what this, how to use it etc, but not having any luck - only finding details of how to paint and leave a textured finish.

So any advise or links to how to paint using a splatter coat and to advise me on how to use it?
 
It's used as a guide so when you key the surface with a flat block wrapped in sandpaper (for example) the spots of paint will remain where there is a concave surface ie a drink or dent.
 
key the surface.... do i need to do that? I expected to just degrease the primed paint and then spray my top coat directly on top of that...
 
So you only need to key between the final coat of the primer and the first of the top coat?

I understand why you need to key or etch the steel before a primer, but why do you need to key the primer before top coat? I thought the primer was designed to work with the top coat directly on top? Or is this just the 'belts and braces' approach?

What are you using to key the surface? Wet and dry? And what grade would be typical for this stage?

Thanks
 
Depends on the final finished look you are after. Look at the primer closely,, any specks of dust/scratches /orange peel etc will be exaggerated by the thin top coat.
I'm out of touch with sandpaper grades now but 400 grit will be fine to use.
Do not use wet and dry for primer use the grey stuff who's name slips my mind just now but is used dry.
Off to Google the name.....
