Oak and Timber Frame Coatings Removal

A preferred method by many conservation officers for the preservation of heritage woodwork within timber-framed buildings. With a dedicated team of experts, they are committed to reviving the authentic charm of historical structures while ensuring contemporary integrity and aesthetic appeal. The company offers a variety of services targeted at treating oak beams, staircases, oak frames, and timber frames.

The hallmark of Cheshire Heritage Blasting’s service is its detailed attention to the delicate removal of surface coatings from timber. Microblasting is a gentle option, often recommended for heritage and conservation work, which involves projecting fine abrasives at a controlled pressure onto the wood surfaces. This technique meticulously strips away years of accumulated paint, stains, and weathering without harming the underlying wood, thus revealing the original, natural timber finish.

What is Microblasting and why should it be used?

Microblasting, also known as precision blasting or micro-abrasive blasting, is a process that uses a fine abrasive media propelled through a small nozzle at low velocity to clean or etch a surface on a very small and detailed scale. This technique allows for precise, controlled removal of surface materials without affecting the integrity of the item being cleaned or processed.

What is the difference between Microblasting and Traditional sandblasting?

The difference lies primarily in the scale and precision of the surface treatment process, as well as the specific applications for which each method is best suited.

In summary, microblasting is distinguished from traditional sandblasting by its lower pressure, finer abrasive media, and precision-focused applications. While traditional sandblasting excels at aggressive material removal on a larger scale, microblasting offers a more controlled and delicate approach, making it particularly well-suited for detailed and selective surface treatments.

The key features of microblasting include:

1. Precision: The ability to target very small areas with pinpoint accuracy makes microblasting an ideal choice for delicate or intricate applications.
2. Control: Users can adjust various parameters such as pressure, abrasive media type, and nozzle size to control the intensity and area of impact.
3. Versatility: Microblasting can be used on a variety of materials, including metals, glass, ceramics, and even sensitive components like semiconductor chips.
4. Minimal Damage: The process is gentle enough to remove only the intended surface layer without causing damage to the underlying material.

2. Environment Protection: Areas surrounding the frames are covered to safeguard against any potential damage from the microblasting process. This includes adjacent building surfaces, windows, doors, and any landscaping.
3. Media Selection: Personnel select an appropriate abrasive media that is aggressive enough to clean effectively but gentle enough to not damage the wood. Commonly used media include fine grits such as crushed glass or walnut shells.
4. Blasting Equipment Configuration: The microblasting equipment is configured with the chosen media, and the air pressure is set at a level that is predetermined as safe for the specific timber or oak being treated.
5. Spot Testing: A test blast is done on a small, inconspicuous section of the frame to ensure that the selected pressure and media will not harm the wood.
6. Microblasting Process: With the right settings confirmed, the microblasting begins in earnest. The technician moves the nozzle in consistent, smooth motions to evenly clean the timber frame, avoiding any prolonged exposure to one area.
7. Continuous Assessment: Throughout the cleaning, the technician closely observes the wood for any signs of wear or unintended effects, adjusting the media flow or pressure as necessary.
8. Detailing: After the bulk of the microblasting is complete, detailing may be used to work on intricate parts of the timber frames, ensuring an even and thorough clean throughout.
9. Post-Blasting Clean-Up: Following the microblasting, a brush-down or air blowoff might be performed to clear away any remaining dust or media particles.
10. Treatment Application: After the frames are clean and dry, additional treatments such as wood preservatives, stains, or sealants might be applied to protect the beams from the elements and enhance their appearance.
11. Final Analysis and Touch-Ups: The cleaned frames are examined, and any areas requiring touch-ups are addressed to ensure a consistent finish across the structure.
12. Site Restoration: Protective coverings are removed, and the site is cleaned to ensure that it is free from any microblasting residues.
