Crack under pressure
Paint cracks as it ages because it hardens, and wood expands and contracts. Get that look almost instantly with this simple technique. To accentuate the cracks, start by applying a stain or paint that contrasts with the top coat of paint. We applied SherwinWilliams Classic Cherry stain and painted on Sherwin Williams no. 6667 Afterglow. Work on one horizontal surface at a time, laying the item on its sides, front, and back as needed. Allow the paint to dry before tackling the next surface.
Drizzle white glue over the surface. Spread it unevenly with a foam brush, but cover the entire surface. The uneven coverage varies the crackle pattern.
As soon as you finish spreading the glue, with a clean brush. start applying a moderately heavy coat of paint
As the paint dries, cracks develop. If the pattern of cracks isn’t to your liking, scrape off the paint before it dries completely, and repeat the glue and paint applications.
