Crackle mediums are used with acrylics to achieve the look of aged paint. Stockade carries three different kinds of crackle. For this post we discovered what the differences were.
To keep the results fair, each product was applied to the same piece of wood with the same application method and in the same environment (humidity can alter the crackling effects). The amount of crackle product applied and the direction of the brush strokes make a big difference in the styles of crackling (apply with a sponge for a less linear appearance). The examples shown above were all made with a thick coat of crackle medium.
In our test we painted wooden squares first with two coats of Americana Heritage Brick (except for the "One Step Crackle" which we painted directly onto the Toffee Colour). When this dried we painted a thin coat of medium on one square and a thick coat on the next. After it dried (Delta says "let dry until tacky") we painted a even coat of Americana Toffee across the top (using even quick brush strokes). The results are shown below (a thin coat of medium is shown on the left, a thicker coat is shown on the right).
Our findings show that both the Delta Ceramcoat's Crackle and DecoArt's Americana Weathered Wood produced almost identical results with identical application requirements. Other were easy to apply and easy to clean up.
DecoArt's One Step Crackle produces a different look as it is a "one-step" crackle. While the two other products cause the top paint to crackle and reveal the colour below, with this product it is the medium that crackles. It produces a as almost a cracked varnish look. It has a shiny appearance but can be varnished over with another finish or antiqued with stain.
Hopefully this provided some insights to the differences between Stockade's Crackle products. It was fun to do this test and neat to watch the crackle work. If there are other products you'd like to see compared or explained further please let us know.
