Thanks anon! It’s an easy trick and there are many ways of achieving that grunge effect. I use Photoshop but I’m sure there are ways to apply this technique in other programs as well.

You’ll need two layers: a transparent design/text on top of a solid background color. We will erase parts of the design instead of adding grunge to the whole pic. This way the design will work even if you change its color or the color of the bg. Here’s Cappy, let’s fuck him up!

The first way of doing this is by finding a good textured, spongy brush. I usually use the Natural Sponge from @kyletwebster‘s Megapack. Set your brush mode to “clear” on the top toolbar. This will turn it into an eraser!

Now just go ham on the drawing you’re grunging up! The more randomly you erase, the better! You can switch brushes to vary shapes and edges. Don’t forget to switch up brush sizes to add smaller scratches too! Tadaa!

If you think you’re not very good at making things look random, there’s a second way of doing this. Textures are your friends! I usually get them from textures.com. As a first step, turn your texture black and white (Shift+Ctrl+U) and play with the levels (Ctrl+L) until it’s mostly white with some black spots.

Then select the black pixels with the Magic Wand tool (make sure that “contiguous” is turned off on the top bar so your tool selects all the black pixels on your canvas). Copy all the selected pixels and paste them on a new transparent layer over your design. Feel free to move the texture around, resize it if it looks better. Now all you have to do is select the grunge you just added (by Ctrl+left clicking on its layer in your Layers window) and press Delete while standing on your design layer. This way only the selected pixels will be erased from your design.

After this, you can delete the grunge layer and enjoy your nastied-up design or do another round of what you just did to destroy it even more. If you want smaller scratches in it, switch to brush and touch it up with the first technique I described.

For Lucas’ logo, I used the brush only. I like to be able to control where the damage happens :) Hope this helped!
