NO stripping, No sanding, No priming, No Sealing!! Honest! Shellac is a sealer—no sealing is needed. Chalk Paint® adheres to the surface better than any primer. (Only use shellac if a bleed through problem occurs, which is very uncommon. This is an unnecessary extra step too. See the section on shellac for more details.)
Make sure your surface is free of rust (unless you want that to show through) and loose paint. Painting over loose paint will not stabilize the failing substrate. You will need to sand that.
If the surface has chipped off paint, varnish, or veneer and you want the end result to be smooth, you will need to fill in the low lying areas. We recommend using Wood Icing™--extra creamy and easier to use than typical wood putties, it is also more cost effective. Wood Icing™ can be stained or painted. If a super smooth surface isn’t necessarily desired, Chalk Paint® can be applied thickly, creating texture that will cover up the imperfections on the surface.
Other than that, make sure your surface is clean and free of dust, dirt and grease. Sometimes a damp cloth will suffice. Other times (like kitchen cabinets) we recommend cleaning thoroughly. Although some people choose to use dish soap, tsp or tsp alternative, we highly recommend a non-toxic cleaner that will not leave behind a residue. (Do NOT use oil soap to clean!) We have found the best cleaner to be Basic H. It is a highly concentrated, non-toxic cleaner that will not leave a residue. We recommend mixing according to the directions for degreasing and using the green scratch side of a Scotchbrite™ sponge. That abrasive sponge aids in getting the surface extra clean while slightly deglossing for the best adhesion possible.
It depends on the color of paint you’ve chosen as well as the color of the piece you are painting over and the technique you are using. If you are doing a light barely-there coverage, you will get a lot more coverage than doing pure white over black and wanting completely opaque coverage. For full coverage, here are the average coverage rates.
A project pot will cover 18-25 sf. That is equal to one very thin coat on your front door. And you’ll need more than one coat if you want solid coverage.
A quart will cover 150-200 sf. Painting two coats on a kitchen table and 4 chairs – or – an average sized dresser and 2 end tables is achievable.
