Hey fellow eco-warriors! 
I’ve recently embarked on a journey to revamp my living space using only natural and non-toxic materials. My latest project involves using milk paint on some vintage furniture I found. I’m absolutely in love with the matte finish and the rich colors, but I’m a bit concerned about durability, especially for pieces that see a lot of use, like my kitchen table.
I’ve been experimenting with different non-toxic sealers to protect the milk paint without compromising its eco-friendly integrity. So far, I’ve tried a beeswax polish, which gives a lovely, soft sheen but requires frequent reapplication. I’ve also tested a natural oil-based sealer that offers more durability but slightly alters the paint’s original color.
I’m curious to hear about your experiences! Have you found a non-toxic sealer that works wonders over milk paint? How does it hold up over time, especially on high-traffic surfaces? Also, any tips on application techniques that enhance durability without affecting the paint’s natural beauty would be greatly appreciated. Let’s share our knowledge and help each other make our homes both beautiful and sustainable! 
Hey @GreenThumbJenny! I’ve been down the same path with milk paint and found that a tung oil finish works wonders for durability without sacrificing the eco-friendly aspect. It does deepen the color slightly, but in a way that I think enhances the natural beauty of the paint. Application is straightforward—just make sure to apply thin coats and allow ample drying time between them. Over time, it’s held up really well on my kitchen chairs, which see a lot of use!

I’m a big fan of shellac as a natural sealer. It’s derived from the lac bug and is completely non-toxic once it dries. I’ve used it over milk paint on a bookshelf, and it’s been holding up beautifully for over a year now. The key is to apply it in thin layers and sand lightly between coats for a smooth finish. It does add a bit of a sheen, but I think it complements the milk paint nicely.

@EcoCraftyDave Thanks for the tip! I’ve heard about tung oil but haven’t tried it yet. How many coats did you apply, and how often do you find yourself needing to reapply it?

@SustainaSarah I second the shellac recommendation! It’s amazing how durable it is, and I love that it’s all-natural. Have you tried mixing your own shellac flakes, or do you buy it pre-mixed? I’ve been considering making my own to have more control over the consistency.

Has anyone tried linseed oil as a sealer for milk paint? I’ve read it’s a good option, but I’m curious about real-life experiences, especially regarding durability and color change.
@LeafyLucy I’ve experimented with linseed oil, and while it does offer a nice finish, I found it took much longer to dry compared to tung oil. It also darkened the milk paint more than I expected. It’s worth a try if you’re patient and don’t mind the color shift!

Tung oil sounds like a solid choice! I’ve been using a linseed oil mix for my milk paint projects. It’s a bit of a process, mixing it with some citrus solvent to thin it out, but the finish is durable and has a nice, natural glow. It does take longer to dry, so patience is key. Have you noticed any yellowing over time with the tung oil?

I’ve been experimenting with shellac as a sealer over milk paint. It’s a bit more labor-intensive, applying multiple thin coats and sanding between them, but the result is a hard, durable finish that really protects the paint. Plus, it’s all-natural and non-toxic when you use the dewaxed, blonde variety. It doesn’t alter the color much, which is a big plus for me. How do you find the tung oil in terms of ease of application compared to other sealers you’ve tried?

I’ve actually used linseed oil on a couple of milk paint projects. It does deepen the color a bit, giving it a richer look, which I personally love. Durability-wise, it’s held up pretty well on my coffee table, but I did notice it needs a touch-up every now and then, especially on the edges. It’s not a set-it-and-forget-it solution, but for the natural finish it gives, I think it’s worth the extra effort.
Linseed oil? Yeah, tried it once. The color change was more than I expected, so if you’re going for that original milk paint look, maybe test it on a small area first. As for durability, it’s okay, but not the best for high-traffic areas. I ended up switching to a different sealer for my dining chairs because they needed something tougher.

I’m a big fan of using linseed oil over milk paint. It really brings out the depth in the colors, and I haven’t had any major issues with durability. My kitchen cabinets have been holding up great for over a year now. Just make sure you apply it in thin coats and let it cure properly. It’s a bit of a waiting game, but patience pays off.

I experimented with linseed oil on a milk-painted bookshelf. The color change was subtle but beautiful, adding a warm glow to the piece. However, I found that it attracts dust like crazy, so I have to dust it more often than I’d like. Durability is decent, but for something like a kitchen table, I’d probably look for something a bit more heavy-duty.

I’ve been using a plant-based sealer that’s been a game-changer for my milk paint projects. It’s made from linseed oil and doesn’t alter the color much. The key is to apply it in thin layers and let it cure properly. It’s held up really well on my coffee table, which gets a lot of use.

That’s interesting about the linseed oil sealer. I’ve been using a shellac-based sealer, which is also non-toxic and gives a nice, durable finish. It does add a bit of a sheen, but I kind of like the way it makes the colors pop. Just make sure to apply it in a well-ventilated area because the alcohol fumes can be strong.

I tried a beeswax polish like you mentioned, and while I love the natural look, I agree it’s not the most durable. I’ve switched to a blend of beeswax and carnauba wax, which seems to last longer. It’s a bit more work to apply, but the extra durability is worth it for me.

Has anyone tried using a water-based polyurethane over milk paint? I’ve heard it’s non-toxic once it cures and offers great protection. I’m curious about how it affects the paint’s matte finish though. If anyone has experience with this, I’d love to hear about it.

I’ve been experimenting with a homemade sealer made from pine resin, beeswax, and a bit of jojoba oil. It’s a bit of a process to make, but it gives a beautiful, durable finish that’s completely natural. It does require some maintenance, but I enjoy the process and the results are worth it.

I’m all about the natural oil-based sealers too. I found that tung oil works great for high-traffic areas. It does darken the paint slightly, but I think it adds depth to the color. Plus, it’s super easy to touch up if needed. Just a quick sand and reapply, and it’s good as new.
