Trying to get rough texture SPI epoxy
 

I am trying to get a rough pebbley finish to my SPI epoxy with no luck. I've tried different spray techniques, rolled it on with different nap rollers, and it still dries very slick. Any suggestions?

Did you try to contact Barry at SPI? He may have some ideas.

Spray some chip guard first....get your texture you want...then coat with epoxy

Or use lower gun pressure ....until it’s spitting out....giving that grainy look
