Glasurit 22 cure time before color sanding

[drcoastline]

What is the recommended curing time for Glasurit 22 before color sanding? Tech sheet indicates cure time 10 hours at 20C (68F). Is it safe to color sand after that?

Second part of the question 1500-2000 how high should I go?

you can sand as tech sheet stated. after 10 hours of air dry time you can color sand and buff. 24 to 48 hours is better if you can wait that long. then they give temps it's not air temp it's the temp of the panel. as air temps and panel temps can be different.

if it's clean and your not dealing with lots of texture ( orange peal ) then 2000 is good if you have some dust and some peal to remove then go with 1500.

Thanks 962. Yes I can wait 48 hours I just didn't want to jump in to soon. I do have dust and orange peel to remove. So I will start at 1500 but I don't need to sand above 2000 before polishing? 2000 is fine enough?

depending on what compound your using at times all you would need to do is sand it with 1500 and then buff it.

got it. Thanks again

I am curious, is there any maximum time to color sand? My 911 was painted a few months ago, and I was hoping to color sand/buff when I get the fenders, doors and hoods mounted and in place which may be a few months yet....

Here is the beast...

you can wait as long as you want to color sand and buff and still get a good shin to the finish.
the down side is after the finish has become totally cured about 3 to 6 mounts time. the buffing will become a little harder to do. what happens is for any reason you may get a little deeper sanding scratch it will be harder to just buff out with the compound. when the paint is still dry and not yet to full cure the buffer will heat up the finish enough to kind of float it around some easily removing the sanding scratches.
when the finish is dry but not fully cured you can sand it with just 1500 then go right to a compound and get a really good gloss back up in the finish.

when the paint is fully cured you will or should 1st sand with the 1500 then go over every thing again with 2000 and then buff with the compound.

That sounds perfect, I must admit I enjoy sanding of that type....sort of zen with a wonderful outcome.

Thanks for the expert advice...
