Dry ice blasting is a highly effective and non-abrasive method for removing paint from timber beams, making it ideal for historic and listed properties. The process works by propelling dry ice pellets at high speed onto the painted surface, rapidly reducing the temperature and causing a thermal shock. This sudden drop in temperature makes the paint brittle, allowing it to detach from the timber. The force of compressed air then lifts away the loosened paint, revealing the natural wood beneath.
As the dry ice sublimates on impact—transforming directly from a solid to a gas—it leaves no secondary waste behind. This ensures a clean, chemical-free process that preserves the natural beauty and structural integrity of historic timber beams.
At Gransden, we specialise in dry ice blasting for beam cleaning and paint removal, offering a gentle yet effective solution for listed buildings and historic properties. This method is often preferred by conservation officers due to its non-damaging approach, helping to preserve the integrity of timber, brick, and stone.
Our experienced team takes a tailored, delicate approach, always conducting small test areas and adjusting pressure to suit the needs of each project. For listed properties, we provide a detailed Historic Method Statement for conservation officer approval, ensuring full compliance with preservation standards.
After dry ice blasting, we recommend applying a natural oil, such as Linseed oil, to nourish the timber and enhance its rich, natural colour. This helps protect the wood while maintaining its authentic, historic character. Our team is happy to advise on the best finishing options to complement your project.
Trust Gransden Dry Ice Blasters for expert beam cleaning that preserves and enhances historic architecture.
