    The three homemade chalk paint recipes

    All three recipes start with flat or eggshell latex paint — the flatter the sheen, the more matte and chalky the result.

    • Plaster of Paris: per cup of paint, mix ⅓ cup plaster of Paris with ⅓ cup cool water until smooth, then stir in. The classic, ultra-matte finish. Use it the same day.
    • Calcium carbonate: per cup of paint, about ⅓ cup calcium carbonate made into a paste with 2–3 tablespoons of water. Smoothest finish and keeps longer.
    • Baking soda: per cup of paint, 2 tablespoons baking soda stirred in gradually. Easy to find, slightly gritty — sand lightly between coats.

    FAQ

    Is homemade chalk paint as good as store-bought?

    For most furniture projects, yes. It sticks well to most surfaces with light scuff-sanding and costs far less, though finishes vary a little by paint brand.

    Do I need to seal homemade chalk paint?

    Yes. Chalk-style paint is porous, so finish with furniture wax or a water-based polycrylic, especially on tabletops.

    How long does homemade chalk paint last once mixed?

    Plaster of Paris batches are best used within a day. Calcium carbonate and baking soda versions keep a few days in an airtight jar — stir well before using.
