In this video, I share a simple hack I use when laser engraving on rough wood surfaces to add color without masking tape. When the wood surface is too rough for tape, I coat the surface with dishwashing detergent before painting. This method keeps the paint from sticking to the wood and only allows it to adhere to the laser-engraved areas. It’s an easy solution to get professional-looking results on your woodworking projects. Watch to see how it's done!
