Thick Paint Supplies

I get asked maybe 10 times a day what kind of paint I use and what colors I use. These are incredibly broad questions nearly impossible to answer in a short DM, so I'll put it all here for you to bookmark and experiment with as you wish. It's taken me nearly 20 years of thick painting to figure out exactly what materials and tools work best for me, my process, and my goals, which might not be the same for you. I'm sharing what I've learned so you can use it as a launching pad for your own experimentation rather than a duplication of my work. Please be mindful to experiment with your own artistic voice and subject matter that is true to you!

Oil Painting Supplies. Gamblin Artist Oils is my preferred oil paint because the consistency is very buttery and the colors are excellent. They often have imperfect tubes on super sale so give them a follow on Instagram here to get updates on when they're available. They go fast! In terms of mediums, Gamblin's Cold Wax is my go-to. It's made of beeswax and will dry no harder than a candle, leaving a smooth, matte finish. I mix about 25% wax into the oil, and make sure not to over-mix because it could get drippy and not as buttery when applied. You can find these products at any art store, but I generally shop at Dick Blick. In terms of exact color choices, I have pretty much every color in stock and mix them to attain specific color variations. Color mixing is something you will need to experiment with on your own to find what works best for your style. Some of my favorites are naphthol red, hansa yellow, dioxazine purple, radiant white, emerald green, and phthalo turquoise.


Acrylic Painting Supplies. While there isn't much comparable to the texture of oil paint, there are certain mediums paired with Heavy Body acrylics that can almost mimic oils. For acrylic painting it's super important to use only the Heavy Body variety. I stock up on large jars of Golden Heavy Body Titanium White and a variety of smaller colored tubes by Golden and Liquitex. If you are on a budget but still want thick, Utrecht will get you pretty close to the look. Definitely avoid any of the following types of paints if texture is your main goal: soft body, basics, house paint, or non-brand name. I use a couple different types of mediums that will help maximize texture and maintain peaks. Liquitex Super Heavy Gloss Gel can create sculptural effects that maintain their high peaks, with a slight shine when dry. Peaks can also be held very well with Golden Extra Heavy Molding Paste. Start with small jars and see if you can tell the difference.

Palette Knives

I suggest purchasing at least five different knives in a range of sizes and shapes and playing around until you find your go-to favorites. Check out the knives at art stores and don't be afraid to delve into knives for cake decorating. Some of my favorite knife sets and offset frosting spatulas are available on Amazon here. Always get stainless steel because they are more solid and will last much longer than the plastic varieties.


This piece below was painted with a 4" offset frosting spatula available on Amazon.


Let me know if you have any questions! Enjoy!!

This is a nice reminder that texture changes mood—thick paint supplies can make a scene feel heavy and tactile, and commissioned originals often carry that same physical presence. I like how your prints and cases make that work accessible, too. Speaking of atmosphere, I recently fell into a horror visual novel where a boy’s love turns into a nightmare; the The False Sun story explained page covers all 20 endings and unlock guides. It pairs surprisingly well with heavy, expressive artwork.

I’ve been browsing the Thick Paint Supplies site and really appreciate how it balances practical materials with finished work—Originals, Commissions, Prints & Cases all in one place. The Recent Posts make it easy to see how heavy-body paint behaves in real projects, especially around texture and layering. When I need a short studio break, I’ve been playing free endless word ladders at

Poople Answer—no daily cap or download, so it’s a handy reset before returning to the easel.

This is a nice resource for anyone who loves working with thick paint—it’s refreshing to see originals, commissions, prints, and cases gathered in one place rather than scattered across social posts. I’ve been using random street-view references to loosen up my texture and color choices, and WorldGuesser has been a fun, free way to explore odd corners and lighting I’d never think to search for. Great for studio warm-ups between larger pieces.

I love seeing how you organize thick paint supplies alongside originals, commissions, prints, and cases—it makes the studio workflow feel tangible. Thick paint can be tricky for texture and drying time, so I’d be curious whether you use palette knives or layered glazes to keep edges crisp. When I need a short reset between painting sessions, I sometimes play a low-poly browser racer; this poly track backup page has custom tracks that are surprisingly good for quick breaks. Do you keep a separate set of supplies for commission work versus originals?

The breakdown of pairing cold wax with Gamblin oils and using cake frosting spatulas for heavy impasto texture is pure gold, Ann Marie! When stepping away from the studio easel and letting thick paint layers dry, playing a quick run on Daily Red Pokémon in my browser is my favorite nostalgic way to rest my eyes. Invaluable supply recommendations for artists!
