Masking isn't working properly

[DiegoM]

When I use a mask to brush out content the mask isn't 100% working. I can still see what I brushed out but it's very faded, as if I set the opacity very low. My brush is at 100% opacity and hardness. My blend mode is normal and I'm working in CMYK because this will be printed. I have attached a PNG so you can see the problem but I intend on exporting as a TIFF. I know I could use the eraser if I really need to but I would rather not. Any help would be appreciated!

Can't really tell much from just a PNG about what you are doing but just guessing is Wet Edges enabled on the brush you are using? Is it set to pure black (RGB all at 0 or K at 100 in CMYK)?

Wet edges were not enabled. I had a tried a 4 color black and full K 100 and that didn't work. Something I tried that did work was changing it back to RGB and painting in black. When I set it back to CMYK and exported I got the full transparency I needed.

That's what you would need, but it can be tricky to get it in a CMYK document, so we would need details of what you did.
