DIY Chalk Paint Test: Cost, shelf life, lumps, durability & appearance. The top two DIY chalkpaint recipes are put to the comparison test. Which DIY chalk paint is better?
I use calcium carbonate (marble dust) because plaster of Paris hardens so easily that you have to be VERY careful how and where you clean tools or containers used to mix it and get rid of the excess itself. It can clog drains even from washing it off YOURSELF over time.
HI, Yesterday, I was checking out sources for calcium carbonate, thinking it was the same lime my family had used on the farm & found out it is NOT. Calcium carbonate & hydrated or slaked lime are totally different creatures, thought you might want to let folks know so they don't buy the wrong thing.
It's kiln dried but it's all subjective, you can use baking soda or powder, can't remember, unsanded grout and probably diatamaceous Earth which is what I'm researching. I've got some on hand so when I saw lime, I thought ground sea urchins. Tums is just chalk, u can probably use it too.
Hey thanks, I ordered Calcium Carbonate and I received a bag with calcium carbonate on it but then the details says that it is lime. I am confused because my uncle used to work at a water plant and the lime that he had to mix in everyday would create sores on his arms wherever it touched his skin passed the gloves. How could that be safe for kids chalk for example?
Yep. She shouldn't keep calling it lime really as it's not lime and that's where the confusion is coming from - this is lime _stone._ Limestone is a sedimentary rock made of calcium carbonate (CaCO3) Lime or Calcium _Oxide_ (CaO) is made when limestone is subjected to extreme heat, changing calcium carbonate to calcium oxide. The extreme heat causes the limestone to chemically release carbon dioxide (CO2). The end result is lime.
@@SashasRevenge You're confusing lime with _limestone_ - Calcium Oxide (CaO) with Calcium Carbonate (CaCO3). Chalk paint (and children's chalks) are made from _limestone,_ not lime. The burns your uncle got were from lime, not limestone. When lime is exposed to moisture, or sweat, a very hot chemical reaction takes place causing chemical burns. See my reply from a few minutes ago explaining a little more.
I AM TOTALLY ASTONISHED YOU WENT INTO SUCH INDEPTH DETAIL FOR US/ VIEWERS!!! WE AND FUTURE WATCHERS ARE ETERNALLY GRATEFUL FOR YOUR TIME AND EFFORT ..BIG BIG TEXAS THANK YOUS ❤️
Thank you so much for going through all of these steps for us, that involved a lot of work on your part. I like using the Calcium Carbonate/ Line the best on what I’ve used it for. Just my opinion only. Great job honey, have a blessed rest of your life.
Thanks so much for doing this. As always, great info given in a concise manner, which I like. I've been experimenting with mixes myself, so this was helpful.
Calcium Carbonate, U$ 3. Quantity: 25 kg bag (55 pounds). You should look for laboratories that prepare it for agricultural activities and the food industry.
Thank you for this demonstration. What is the ration recipe for each? Also I already have a 25 kg bag of "Hydrated Calcium" which is used for making "white wash, mortar and plaster" according to what is labeled on the bag. What is the difference between "Hydrated Calcium and Calcium Carbonate. I and having difficulty finding out the difference and if the Hydrated Calcium can be interchanged with the Calcium Carbonate. Do you know?
Massively late but I just came across your video while searching for a DIY furniture wax and I continued to keep viewing your others lol. Your amazing on your descriptions and explanation’s btw. I haven’t tried the PoP nor the lime BUT I do use cornstarch, mix it with a little water (to get it smooth, it does not clump when mixed with paint, nor does it clump up after sitting) and then in your paint, however, it will lighten your chosen paint color a bit and it is best mixed in small batches, it will not keep for a period of time unless it’s in a very cold room or a refrigerator lol I will be trying the lime soon 😊 Again, your video’s are so much appreciated especially since I pretty much DIY everything.
We use talc and you get about 30 days shelf life and the opacity is crazy good. Maybe you can do a test on it on that combo. Excellent tutorial much appreciated.
Brilliant demo thanks I have been wondering which is best. I guess the plaster Paris is a pain cos u have mix small batch at a time due to hardening. Calcium carbonate mix chalk paint can be stored right? Does the colour of the paint ur using go lighter with calcium carbonate?
I prefer calcium carbonate even though Plaster of Paris is cheaper . It does seem to store pretty well but I try to use mine within a month of making it. They both lighten paint but I believe the plaster of Paris lightens a lot more.
Hi, your videos are super helpful. Thank you so much! Question: I want pitch black color, do you think adding POP or CaCO3 lightens the color? Will it turn dark grey like yours? Any suggestions please?
I have found that using calcium carbonate to make chalk paint makes a darker black. I have stopped using POP for black. I have also added black mica powder, which is used to dye Resin, to get the paint even more black. Here is my Calcium carbonate recipe.

Thanks for this really informative video. What was your proportions for each recipe? And what paint did you use? Thank you for your effort. The furniture looked beautiful btw.
I don't think the time to cure is any different. I can pack and ship chalk paint furniture after a few days. It can stand light use but the more time passes, the better. I also use both recipes and do not see any durability issues between the two.
I read you have to use calcium carbonate with acrylic paint and can not use plaster of paris. Do you know or anyone know if this is true. Also can I substitute type S lime for calcium carbonate? Anyone?
were you using the same brush through the whole painting test? If so then just maybe the brush held onto the lime or plaster, from the first mixing. Just guessing. Have a great day!
@@NashvilleRestoration thanks so much. Love your videos. We are teaching furniture flipping to a group of homeschooling kids and your videos are incredibly helpful since us parents are learning as we go too 💖
Yes mixers Balls work. My two favorite these days, a paint mixer that goes on the end of a drill and a food mixer I bought new for $10 at Dollar General that I just use for paint.
Yes they have different characteristics. But actually calcium oxide is derived from calcium carbonate by heating. The resulting material from this process is called quicklime, (Calcium oxide) and is used to make cement, concrete & roads, iron industry and to neutralize acidity (in lakes). Calcium carbonate (called lime or limestone) is used in garden, agriculture, health supplements, chalk etc. In using in chalk paint, pick calcium carbonate as ingredient.
More coming soon! I seem to be doing a lot of comparisons and "10 ways to ......do whatever, seal chalk paint, etc". I have a few more of those coming up.
To preserve these paints further, carefully tip 1/2in of water on top forming a layer of water over the paint and put it in the fridge! Also I pour my paint through a kitchen strainer to mix it back up and remove any funky bits. Cheers doll!
