Chalk paint cracking is one of the problems if you use chalk paint. You can fix them, or you may even want to create crack effect to create aging effect. It’s your choice.
Crack in
the furniture, especially wood is usual if you have old furniture. Before
painting you must prevent further chalk paint cracking.
You can use wood glue like Gorilla Glue to fill the cracks and coat
them with wood filler. After dry, you can sand the furniture before apply the
chalk paint. You need to clean the surface also. The crack can also happen
after second layer of coating. The paint will peel off and crack.
To avoid
the cracking in chalk
paint you can rub the furniture with abrasive pad like Scotch Brite and Tri
Sodium Phosphate Cleaner. After that, you can wipe use soft cloth and Denatured
Alcohol to remove any cleaner residue. You can sand the furniture use 150 grit
sandpaper and directly clean with pad and TSP before painting. If the furniture
still feel sticky, you can coat with Shellac on the sticky areas only or even
entire surface.
Other
Chalk Paint Problems
Besides chalk paint cracking, after first coating dry; you
can also see stains. For this problem you can use shellac too or water or oil
based lacquer depend on the stain type. After dry, you can apply the second
coating of paint before waxing. Another problem may also occur after second
coating after waxing. After the first coat of wax, your furniture suddenly
looks streaky or shows some wood under. It usually happens in the light colors
like Old White or Country Grey.
If that happen, don’t be panic to soon. You must let the wax dry first
to see if it can back to normal. If not, just apply paint in the areas that
imperfect then wax again. It will make the wax uneven, but you can dry it and
apply the second coating. Other chalk paint problem is you
may apply too much wax. You can fix that by rubbing it with a synthetic green
pot scrubber. If the wax is too much wax, you can use 280 to 350 grit sandpaper
gently without peel the paint.
After the wax look good, smooth
with wax brush and polish it. Another problem in chalk paint is after clear wax, you may
want to apply dark wax, but it is uneven and blotchy. You can use green pot
scrubber again and sandpaper too. But, you may need to repaint your furniture.
Next, because the chalk paint usually dry fast, and even faster in summer; when
the second coating make the first coat to peel off, you must pause the work and
give another two hours rest before start to coat again.
