Hey fellow eco-warriors! 
I’ve been diving deep into the world of natural paints for my latest home renovation project, specifically focusing on exterior walls. I’m torn between using lime wash and silicate paint. Both seem to have their merits, but I’m really curious about how they stack up in terms of durability over time.
I’ve previously used Earthborn Claypaint for interior walls and loved the breathability and the rich, matte finish it provided. However, exterior walls are a whole different ball game, especially with the unpredictable weather we’ve been having. I’ve heard that lime wash offers excellent moisture regulation, which is crucial for preventing damp, but I’m concerned about its longevity. On the other hand, silicate paint (like Keim’s) is praised for its durability and ability to bond with the substrate, but I wonder how it fares in terms of environmental impact.
Has anyone here used either of these paints for their exterior walls? How have they held up against the elements? Also, considering the environmental aspect, which one would you say is more sustainable in the long run? Looking forward to hearing your experiences and insights! 
Hey @EcoPainterJane, great topic! I’ve used both lime wash and silicate paint on different projects. Lime wash is fantastic for moisture regulation, as you mentioned, but it does require more maintenance. I found that it starts to fade after about 2-3 years, depending on the weather conditions. Silicate paint, on the other hand, has been incredibly durable for me. I used Keim’s on a project 5 years ago, and it still looks as good as new. The key is proper surface preparation. Both are eco-friendly, but if durability is your main concern, I’d lean towards silicate paint.

I’m all about that lime wash life! 
It’s not just about the moisture regulation; the aesthetic is unbeatable. Yes, it might need a touch-up every few years, but I see it as part of the charm. It’s like the walls are living and breathing with the house. Plus, the application process is so satisfying. It’s definitely more labor-intensive than silicate paint, but for me, the results are worth it.

@GreenThumbGary, thanks for sharing your experience! The maintenance aspect of lime wash is something I’m a bit wary of. Could you elaborate on the surface preparation for silicate paint? I want to make sure I get it right if I go that route.

@SunnyDaysSam, I totally get what you mean about the aesthetic of lime wash! It’s so unique. Do you have any tips for someone trying it for the first time? I’m considering it for a small exterior wall but a bit nervous about the application.

@EcoPainterJane, sure thing! For silicate paint, the surface needs to be clean, dry, and sound. Any loose material should be removed, and it’s crucial to ensure the surface is alkaline. If you’re painting over old paint, a test patch is a good idea to check compatibility. Also, applying a primer recommended by the silicate paint manufacturer can make a big difference in adhesion and longevity.

@RainbowRita, absolutely! First off, make sure you’re wearing old clothes because lime wash can be messy. Start with a clean, damp surface to help the lime wash adhere better. Apply it in thin layers with a masonry brush, and don’t worry if the first coat looks uneven – it’s all part of the process. Let it dry completely between coats. And most importantly, enjoy the process! It’s a bit of an art form.

I’ve been using lime wash on my cottage for years and honestly, the maintenance is part of the charm. It fades, sure, but reapplying it every couple of years feels like renewing a bond with the house. Plus, the way it weathers gives the place character. Silicate paint might last longer, but it doesn’t have that same soul, you know?

Just chiming in to say that silicate paint’s durability is unmatched in my experience. I used it on a community center project, and after 7 years, it still looks pristine. The upfront cost is higher, but considering the longevity, it’s worth it. Plus, it’s eco-friendly, which is a big win for me.

I’m all about the environmental impact, so I went with lime wash for my home. It’s natural, breathable, and the production process is less harmful than silicate paint. Sure, it might not last as long, but for me, the sustainability aspect outweighs the need for frequent touch-ups.

I think it really depends on the building and the climate. I used silicate paint on my house in a rainy area, and it’s been a lifesaver. No mold, no peeling, just solid protection. But I’ve seen lime wash work beautifully in drier climates. Maybe the choice should be more about matching the paint to the environment rather than just durability or eco-friendliness.

I’ve been using silicate paint on my exterior walls for about five years now, and honestly, it’s been a game-changer. The durability is top-notch; it’s like the paint just becomes part of the wall. I haven’t noticed any fading or peeling, even with all the rain and sun we get here. Plus, it’s pretty low maintenance, which is a big win for me.
Lime wash all the way for me. There’s something about the way it ages and changes over time that I find really appealing. Sure, it might need a bit more care, but I think it adds character to the house. It’s like each touch-up tells a story. And the breathability factor is a huge plus for keeping the walls dry.
I’m on the fence about this. I love the idea of using natural materials, but I’m worried about the longevity of lime wash. Has anyone had any issues with it wearing off too quickly? I’m leaning towards silicate paint for its durability, but I don’t want to compromise on the environmental aspect.

I’ve used both, and honestly, it depends on what you’re looking for. If you want something that’s going to last and not require much upkeep, go with silicate paint. But if you’re after that unique, matte finish and don’t mind a bit of maintenance, lime wash is beautiful. It’s all about what you value more.

The environmental impact is a big deal for me. I’ve read that silicate paint is more eco-friendly because it lasts longer, so you’re not repainting as often. But lime wash is natural and has a lower carbon footprint. It’s a tough choice, but I think I’d go with silicate paint for the exterior just for the durability.

I think the key is in the preparation. No matter which paint you choose, if the wall isn’t prepped properly, it’s not going to last. I’ve seen lime wash last for years when applied correctly, and silicate paint can fail if the surface isn’t right. Maybe the focus should be more on the prep work than the paint itself.
