Historic Building Masonry Laser Cleaning

I recently spent a day with Z-Beam running a wide range of real-world laser ablation tests on antique and restoration items, and I was extremely impressed with the rig, equipment and the support provided by Todd Dunning. Todd came out and worked through multiple test scenarios with me involving antique outboard motors, vintage National Cash Registers, old scales, wood components, and other restoration pieces. The goal was not a simple demo, I wanted to thoroughly evaluate how effective the laser ablation would be across different materials, coatings, finishes, oxidation levels, and restoration situations. In essence to bypass the video hype and see if this solution would be a good fit for my line of work. What stood out most was Todd’s willingness to experiment, adjust settings, explain the process, and genuinely work through the pros and cons of each approach. We tested a broad gamut of materials and applications, and the experience gave me a much better understanding of where laser ablation excels compared to traditional media blasting methods. As someone who already owns new media blasting equipment, we both agreed that I should focus on soda and glass bead blasting. The decision had nothing to do with the quality of the Z-Beam system or the support I received. In fact, the experience increased my respect for the technology and its potential, especially for delicate or high-value restoration work. If you are considering laser ablation for antiques, restoration, industrial cleanup, or precision surface preparation, I highly recommend spending time with Todd and the Z-Beam team. Very professional, knowledgeable, patient, and genuinely interested in helping customers understand the technology before making a decision.
