Shellac is an important product to have your in your painting tool box!
Shellac is a sealer. Meaning it used prior to painting as insurance that wood tannin, water marks, and certain color stains do NOT bleed through.
Real quick- if you need to use shellac- typically you would do it in this order:
1. Shellac (Most importantly- remember with this solution – that you cannot “spot treat” water mark or “issue” areas- rather you must do the whole section of the piece of furniture. For example- water marks from a drinking glass on the top? Shellac the whole top, not just the water mark.)
2. Lightly sand after using to prevent paint from crackling.
3. Paint with Chalk Paint®
If you realize you need to shellac after applying Chalk Paint®- that is okay…go ahead and apply the shellac. Just remember you CANNOT apply shellac directly over wax! So, you will need to lift the wax using mineral spirits. Lightly moisten a rag and wipe your furniture. Wipe edge to edge- not circular. Also- make sure to NOT drip mineral spirits on to your floor. The rag should be moist, not dripping wet. The piece should feel almost like it did prior to waxing after removing the wax.
I prefer to use shellac in a container. Do not shake the shellac but rather stir it or roll the container in your hands prior.
I use a lint free, cotton rag to apply the shellac. I usually take a rag and fold it into four’s. The I dip an edge into the shellac and wipe it on the piece in the same direction that I will be applying the paint. (usually the same direction as the wood grain.) I prefer to use the better than cheesecloth rags we have available here on our shopping cart.
Give the surface about 15 minutes to dry, and then repeat with a second, (uniform and thin) coat of shellac.
Never apply it thick. That can lead to problems too.
But – I often use the analogy, “Measure twice, cut once.” So, two uniform coats is best. Sand lightly after applying Shellac so that your paint does not crackle.
Having to apply shellac when painting with a “white” Chalk Paint® is sometimes necessary over certain surfaces.
