Can you spray enamel paint on top of acrylic paint, without any reaction?

Hi Guys,

 

As the title says above, I'm sure this question has been aired before but I cannot find it. I just want to be sure before I commit with the airbrush.

 

All the best,

Hi Martyn

 

I do all my resprays with either Howes or Phoenix enamels after stripping the loco and priming with Halfords Grey or White paint, which is acrylic of the high performance variety.

 

Having said that, I would not recommend spraying enamel over normal acrylic paints, I would use one or the other and not mix as you may get a reaction that cracks the paint.

As long as the base coat is fully cure, I dont see you having much issue.

Obviously do a test piece first.

You can safely put acrylics on top of enamels and vice versa as long as the underlying paint is dried hard. That means at least 48 hours for enamels and 24 hours for acrylics. As Spitfire2865 says, if you're not confident try a test piece first. I'm sure you'll have some scrap material you can use for that.

I have a number of test pieces where enamel paint or varnish was applied over acrylic, which resulted in an orange peel effect.

I regularly use acrylic over enamel - but never the other way around.

Thanks for all the advice Guys, like you say I'll do a test piece first, better to be safe than sorry.

 

All the best,
