First...clean your piece really good! If using a chemical cleaner, wipe down with water after.
The most important thing to remember when painting fabric with chalk paint is...you want to "stain" the fabric, not "paint" it. This means water is your best friend!
Gather your supplies...a spray bottle filled with water (I'm using an old rinsed out 409 bottle right now), a mixing cup, your paint, a large paint brush, and a couple of small artist's brushes to get into the little creases.
Have a question about this project?
Beautiful! How much of the Carbonate powder did you add to the paint? and, I know you said it was "oops" paints but do you know what sheen it was? (flat, eggshell, satin, etc)
They were all satin
I mixed up 6-7 ounces of paint at a time
You'll need any paint, latex (these are mostly your wall paints) or acrylic (these are mostly your craft paints), a mixing cup, a spoon, an 8 ounce container (or larger/smaller depending on your needs, just adjust accordingly), 3-4 tablespoons of calcium carbonate (add more/less depending on your preference on how chalky you want your paint), and HOT water.
Pour about 6-7 ounces of paint into the 8 ounce container. Measure out approximately 3-4 tablespoons of calcium carbonate and add it into your empty mixing cup. Then, slowly add HOT (as hot as the tap allows) water until you make a thick pancake like batter. If you prefer a thinner paint, add a bit more hot water. I prefer thick paints since I mist my surface as I paint to avoid brush strokes. Stir the mixture until the calcium carbonate has completely absorbed, takes about 30-45 seconds. Then add the mixture to your paint, mix very well 😁
I painted my chair like you said but the cushion (which is removable) got all cracked and peeling. What did I do wrong?
Cracking is typically a sign of too much paint and not enough water. The paint ended up lying on top of the fabric rather than soaking in and "staining" the fabric.
Sand back the paint/or peel it off if possible, sand fabric using 220 grit sandpaper to remove any residues, then paint again using more water than you did last time. You want your paint to be liquid, if using a thicker paint, you may have to water it down 60/40 water/paint, or even 70/30. Then be sure to really spritz the fabric, make sure it is completely damp before painting. Then take your paintbrush and rub the paint into the fabric, don't let it just lay on top. Just keep it in your head that you want to "stain" the fabric, not paint it. Numerous thin coats is the way to go
Allow to dry, sand well with 220 grit sandpaper, and repeat 😉
If applying to leather, you need the coats to be even thinner or else you'll have cracking.
Could you use chalk paint & wax to paint a Lloyd Loom or wicker chair?
Absolutely..you'll want to clean it extremely well first to be sure the paint adheres to the surface well
