I sealed the inside and outside of my clay pots with a clear lacquer and this prevented moisture from getting into the porous clay that causes the paint to peel off. I used craft paints and then sprayed the same clear lacquer over the designs. Has lasted for years inside and outside. Have fun!
Once your pot has been cleaned and is dry, then apply a light, even coat of spray sealant to the inside of the pot. Be sure to cover the bottom and the sides. Terracotta is porous, so it will likely soak up the first coat. This is normal. Simply wait for this coat to dry before applying another coat. You may need between two or three more coats. Allow each coat to dry and lightly sand the coat before applying another. The sealer is important, because it will prevent moisture from leaching through to the outside after the pot is planted.
Consider sealing the outside of the pot with an oil based spray-on primer. Apply a light, even coat. You can apply a second coat, if necessary, once the first one dries. Applying some primer will not only help you achieve a smoother finish, but it will also prevent the pot from soaking up any paint.
Also once painted, apply a sealant.
Set the pot aside to dry for at least 2 to 3 days before planting.
If you plant too soon, the paint may not be fully-dried yet. The moisture form the soil may cause the paint to bubble, crack, and peel away.
