So it's been over 90 degrees every day in Iowa for a while and I am getting ready to spray my firewall with black epoxy. I have reducer on hand but am unsure when and how to mix it with the epoxy and activator. Any pointers?
Are you wanting to spray it as a sealer or a primer?
For a sealer coat that can be sprayed over in just an hour or two
then a 1:1:1 is good.
As a primer where you need to wait till the next day to paint over
then it's your choice of what to make it lay a little smoother,
I usually go about 10 to 20% reducer when real hot.
that does help get a slicker finish.
If you're planning on sanding it and the smoothness is not as important
then no reducer at all.
I always do, but it's really a personnal preference.
How you spray, size of tip, a lot of things effect the performance of spraying.
Some do fine with no reduction at all, I reduce it just to get a little slicker finish
I need all the help I can get
