Paint Hardness and V carve Quality - latex paint not cutting well

[chein]

Hi,

I am wondering if anybody has experienced latex paint not cutting on edges of a v carve? I attached a picture. The black latex paint I use cuts super clean but the blue for some reason just leaves bits behind. It made me thing that the black has a different latex base that is harder and maybe cuts or adheres better. It consistently happens on the blue.

I am using Amana insert V carve bits 60 deg at 40ipm 18000rpm. I have tried second passes, clear coating, as well as CMT laser point bit with no luck. I was thinking maybe I should change my paint to oil based or some other sign paint people might recommend?

Any input would be greatly appreciated!

Depends on what you're using it for. Those look like trail markers: how do you intend to fill the reliefs? Primed properly any paint should "rout" as easily as the next. I'm not a fan of latex for sign work although I know lots of people use it, mostly on HDU. I'm of the school of using enamels and anymore 2 part urethanes. How did you prep that piece and what is it made from? Those answers can guide us better with a response.

Latex can take up to 30 days to fully cure. Perhaps the blue was fresher?

Thanks for the responses,

The signs are decorative mountain bike trail markers for indoor use (mudrooms etc.). People are crazy about there favorite trails! I have been leaving them natural wood so no painting of the lettering. I will see what I can find at the paint store for enamels. It looks like there are water based enamels as well. Maybe less smell.

Good to know it has a curing time, I didn't know that. In this specific case the blue had more time to cure than the black.

I think I might just have to try different paints until something works! Anything to avoid using a toothbrush to clean them after cutting.

I found the one shot online. Thanks. I also found a paint with Benjamin Moore that is a waterborne oil paint that I am going to try. Low VOC.

Thanks,

I'm kind of old school when it comes to paint. I use lacquer whenever I can. It's certainly not low VOC but it dries in minutes, can be recoated without sanding and produces a beautiful finish regardless of the humidity.

I'm with Cory and the lacquers are your friend.
