Floquil drying time

I've never had that problem, it's always dried pretty quick for me. Are you using straight from the bottle? Are you making sure it's mixed well?

 

What "plastic structure"?

Oil or water based paint? I'm guessing water. Was it dry to the touch?

 

Often plastic surfaces can be very smooth, and paint doesn't adhere very well. When you go to put a second coat on, the new paint can reactivate the first coat. Also you should be using a very soft bristled brush to apply that second coat.

It is oil based floquil right out of the jar. It does seem a bit thinner than some of the other colors I have used. I thought i may have not stirred well but i double checked and it seemed consistent throughout. It is being placed on an ihc kit, and yes, over very smooth plastic. Seems worse on the flatter smother surfaces. I tried another color on top and it also seemed to reactivate the first coat

And yes it was dry to the touch

Did you use primer? That can help, but it may be too late to go back on this project. 

 

If it's not too much work, you might consider using some solvent to remove as much of the failed coat as possible. Test the solvent on an area that won't be seen to make sure it doesn't damage the plastic. Then try the primer.

 

One more tip: instead of stirring your paint, get some BB's, put 3 in the jar, and shake very well.

I've had the same problem with Floquil enamels - give it a few days and it will be fine.

Thank you for all of the advice. I will give it a go again tomorrow, with a softer brush. I did use the primer on another project with better results. I guess I should have used it on this project. Lesson learned. Hope I do not have to strip it off. Thanks. Jeff

The weather has slowed down the drying time lately.

 

If you airbrush it on, you can almost dry it with air from the brush if your coats are not super thick.  Most things do not require primer.

Gents,

I'm almost 100% sure that most of the time when dealing with plastic kits you need (it is recommended) to wash the pieces w/ soap and water prior to paint application due to the mold release agents used in the casting/forming process. That might be creating a bond breaker between the plastic and the paint...just food for thought.

Just an update. I applied second coat today after 4 days drying time. I used a soft brush with a light touch. Seemed to work much better and did not reactivate first coat. I think leaving the parts in my garage out of the ac may have helped, or maybe it was the 4 days. Next time I will first wash the parts with soap and water and see if that helps. It was def worse over the smoother surfaces, but again, this time success Thanks again.
