Just about any product will stain timber. Coffee is no exclusion, and if used on any sort of timber, it is going to create a vintage finish. Coffee is slender — so thin that if applied to wood, it is going to sink deep into cracks, crevasses, imperfections or open pores. It won’t sink as rapidly into hard grain but instead seeks out the delicate grain. This leaves the wood with an antique look. The coffee soaks in at different levels, highlighting imperfections in addition to delicate and hard grain patterns, with the final result characteristic of antique timber that has withstood the test of time.
Eliminate the doors and doors in the cupboards. Utilize a drill/driver to remove the hinges in the doors. Lay them out across two sawhorses.
Put on a dust mask, and mud any varnish or lacquer in the doors and cabinets utilizing 100-grit seams attached to a hand block. Sand parallel to the grain only. If the cupboards are new, sand them exactly the exact same manner.
Brew a pot of coffee at least twice as powerful as you would like when you drink it. Liberally apply the coffee to the cupboards and drawer fronts using a sponge. If the coffee starts to dry before you’ve added coffee to all of them, stop and wipe the coffee off using a cotton cloth. Continue with the remainder of the cupboards until everything is consistently wet with coffee. Wait 15 minutes and wipe everything deep.
Apply another coat of coffee to the cupboards and doors if it’s not dark enough. It’s OK if everything appears blotchy. That’s part of the result, and it won’t be quite as noticeable after you’ve completed them. You’ll also observe that deviations in the grain pattern might have streaked the surface of the timber. That’s fine too and to be expected. Allow the coffee to dry immediately.
Apply fresh coffee to the cupboards, doors and drawer fronts in case still not dark enough. Allow 24 hours to get the coffee to dry before applying lacquer or varnish. Reassemble the cupboards once everything is dry.
