Does anyone know why my gloss clear coat dulled?

[CustardBug]

Hello, I'm trying to paint a Friday the 13th hockey mask using a high gloss patina varnish (this stuff to be exact) to give it a yellow look as well as acrylic paints on top. When I was done I sprayed Krylon Fusion gloss crystal clear to seal it and it made the whole thing dull. Does gloss on gloss dull? Any other suggestions on how to seal my acrylic paint or how to make it shiny again?

How long after you put the initial color down did you wait before you applied the clear? Generally, it takes anywhere from 4 to 7 days for paint to fully cure, believe it or not. If the layer before the clear wasn’t fully cured it will dull immediately.

I waited over a day for the varnish to dry but the acrylic paints only a half hour or so. I've never had an issue with my acrylic paints dulling though.

I’m pretty sure your clear even sped up the processing as this stuff is designed to “yellow” over time.

But why did it matte? I don't think it's suppose to matte over time.

If it is completely dry now, I’d say hit it with Krylon Triple Thick Clear and it should gloss right up.

I'm going to wait a few days just to be sure everything is dry but I might try this stuff, thanks. Maybe it's more compatable with the varnish being kind of an art supply.

A few issues. If you applied it in a high humidy air, it can dull. Over coating/thick layering it can cause a dull coat. Not enough time to cure also. Give it time, after is has absolutely dried, to buff with an ultra fine cloth, glasses lense wipe will do, LIGHTLY. If that does not work, you may need to try the triple thick Krylon coat as a last step.

As tripoli said it sounds like it has bloomed. Moisture has made it cloudy matt on the surface. A cutting compound polish like T-Cut would get rid of it or lightly sand the surface and reapply the gloss clear in a warm dry environment.

The paint and varnish might be having a chemical reaction. I've had that happen with fusion a few times, as it's designed to chemically "bond" to plastics. Some times it looks great, a few times it looked terrible.

Have you tried any different kinds of clear coat? Could also be moisture as some are saying since it is summer time but I didn't think it was all that humid.
