Why does paint crack?

What causes paint to crack? Insufficient surface prep is the main culprit behind crack attacks. Over-thinning your paint or applying it too thinly can also cause it to split. Conversely, a heavy hand while painting can lead to what’s called mud cracks, where too-thick paint dries with a clumpy, swollen look.

How do you crack paint?

Apply a top coat of flat latex or acrylic paint. Brush one coat only of flat latex or acrylic paint over the crackle medium or glue. Brush your top coat on lightly to get thin cracks and brush on a heavy coat to get large cracks. Use a spouncer brush to sponge-paint the top coat if you want spider web-like cracks.

How to make crackle paint?

Prep Your Piece. First things first: get your chair or table or whatever you’ll be crackling ready to go.

Choose Your Color Combo. The fun thing about crackle paint is that the base colour will show through when the top layer crackles.

Paint the Base Colour. Once the primer is dry and you’ve committed to a colour scheme,paint the entire piece in your base colour.

Paint on a Layer of Glue. Now paint on a layer of good ol’ Elmer’s glue (or another similar white glue).

Let Dry. Now,this is important: if you’re using one of the many crackle products sold at craft stores,you’ll wait until they are completely dry.

Top Layer of Paint. Now for the top layer! Be attentive here: You only want only ONE layer of top paint. That means ONE stroke of paint.

Watch the Cracks Appear! The crackling will begin right away. As the glue dries,the paint will shrink,creating the lovely cracking effect.

Seal It. This is optional. If you don’t seal your piece,it will look more authentically old. However,it will also continue to chip and crack with age.
