What Supplies Are Needed To Paint Rocks?

The essential supplies that you need to start painting rocks are as follows:

  • Rocks! You can go fine rock outside, a beach is ideal. Definitely look for flat rocks that are smooth. If you can’t get decent rocks, you can buy them here: Natural Rocks For Painting
  • Rock painting pens – Although I have already shortlisted the top 5 paint pens, my favorite is Posca paint pens for rocks.
  • Along with the paint pens, you might also need some paintbrushes and other painting supplies, which will give your rock paintings a unique look.
  • Sealer – To keep your rock paintings intact, you need to use a spray-on sealer.
  • Paper towels or cloths to help clean in case you make a mess.

Are Posca Pens Toxic?

Posca paint pens for rocks use pigment paint and has a similar application technique as the other acrylic paints in the market. The water-based ink pigment used in these paint pens are not toxic and gives rich and dark color production.

 Although since these pain pens are not a cosmetic product, they are not tested with regards to dermatology standards. Therefore, it is advisable that you first test the paint before fully using it.

Do Posca Markers Wash Off?

The paint from Posca Markers can be easily washed off if applied on a non-porous surface. The smoother or less porous the surface, the easier is it for posca paint to be washed off. Posca paint easily washes off skin when rubbed thoroughly with water.

It is important to note the Posca ink washes off easier when it is still wet. The dryer it is, the harder it becomes to wash off.

Can You Paint Rocks With Sharpies?

Yes, you can paint rocks with Sharpies. But should you? Only in some situations. Using Sharpies on rocks is only good for applying final touches, like outlines or details. The reason for this is that because Sharpies use ink, not paint, you can’t layer them well enough.

If you want to use Sharpies on rocks, I highly recommend layering your designs with paint pens or acrylic paint first. Then use Sharpies as the top layer for any added details or outlines. Dark-colored Sharpies work best over top of light-colored paint. If you are using dark or mid-tone paint, light Sharpies will not have enough opacity to cover.

How Do You Waterproof Painted Rocks?

The best way to protect your painted rocks from any kind of water damage is to coat them with a sealer. One of the best sealers available in the market is Krylon 1305 Gallery Series Artist and Clear Coatings Aerosol, which makes your rock painting completely waterproof.

When sealing rocks with aerosol spray, you want to make sure you do it outside, to keep vapors out of the house. To mitigate overspray getting on other surfaces, make sure you have some paper or cardboard to put the rocks on. Then spray each side allowing dry time in between both sides.

On the other hand, if you use high-quality paint pens such as Poscas, then you don’t need to use a sealer. Posca paint is waterproof to beg with. However, I have notices fade over time which is likely down to UV rays. All things considered, no matter how good the paint pen you use, I like sealing my painted rocks. A good art sealant keeps painted rocks prefect for years, even when kept outdoors.

What Is The Best Sealant For Rock Painting?

The Krylon 1305 Gallery Series Artist and Clear Coatings Aerosol is a sealer that not only protects your rock paintings from water but also protects it from the harmful UV rays. With this sealer on, you can leave your rock paintings outside, and they will keep shining like new even after a long time.

There are other brush-on sealers. But I don’t recommend them for rocks. Brush-on sealers, because they rely on a brush, lead to paint smearing due to friction of the brush.

Final Thoughts

In the end, Posca Paint Pens are the best all-around paint markers for rock painting. These flexibly, high-quality Japanese markers are simply amazing. That said, if you are on a tight budget, the other options are still great for any rock painting project. If you need refillable markers, Konker Paint Pens are the only option. No matter what brand you go with, I hope you seal your artwork so that you can enjoy it for years to come. Happy painting!
