When using chalk paint does it leave a satin finish?

It leaves more of a flat finish, but you can go over it with some satin poly.

If you want a satin finish, you will need you use a satin finish paint. Chalk paint won't give you that look, even once you apply wax. It's just not that type of paint. Chalk paint gives you an aged look, not a satin finish. If you apply a varnish over it, you may achieve a satin look, but it's iffy. It will depend on the original piece & how you apply the chalk paint. There are many variables.

Lighty rub over with fine grain wire wool and use a clear wax then buff off annie sloan products are the best

You'll have to seal it with a polyurethane to get anything other than a dull finish. I make my own chalk paint with different paint finishes and none of them leave any kind of sheen. But, it is easy to make and use chalk paint, just make sure your furniture or cabinets are clean before you paint them. Here is a pc I did with homemade chalk paint (made with plaster of Paris), homemade furniture wax and a polyurethane top coat. The china cabinet is without a top coat (dull sheen) and the table is with semi gloss polyurethane top coat (some shine).
