Understanding the Differences
When it comes to preparing wood surfaces for restoration, two popular methods often come into play: crushed glass blasting and sanding. While both techniques aim to achieve a clean surface for staining, they have distinct differences that can significantly impact the outcome of your project.
Crushed Glass Blasting: An Effective Preparation Method
Using ultra-fine 50/100 crushed glass for media blasting is typically the best preparation method for all types of wood. This technique slightly profiles the substrate surface, opening up the pores and allowing stains to penetrate deeply into the cell structure. As a result, the wood receives superior protection against harmful UV rays, rain, and snow.
The Downsides of Sanding
On the other hand, sanding or grinding is a labor-intensive process that can take weeks to complete. While it does create a smooth surface, it essentially closes the pores of the wood. This smooth finish prevents the stain from penetrating adequately, leading to a surface that may only offer short-term protection. Instead of sinking into the wood, coatings on sanded surfaces tend to form a film. Unfortunately, these film coats are prone to peeling and delaminating, which means more frequent maintenance will be necessary.
Is Crushed Glass Environmentally Friendly?
Yes, crushed glass blasting is an eco-friendly option. It replaces the need for toxic chemicals and is 100% silica-free. Additionally, it naturally dissipates into the environment in a manner similar to how sand is applied to grass for improved drainage, making it a safe choice for both your home and the ecosystem.
The Mess Factor: Is Crushed Glass Blasting Messy?
Yes, crushed glass blasting can be messy, especially if you’re working on an older log home that requires the removal of an old finish. The fine glass medium, akin to table salt, creates a fine dust when it impacts any surface and becomes airborne. To mitigate the mess, we take careful precautions. We wrap all interior perimeter walls with polypropylene, securing it with staples and tape to prevent dust from entering through any gaps. We also cover all furnishings to protect them from dust. If your home is already caulked or chinked, this extra step may not be necessary.
Conclusion
Choosing the right preparation method for your log home restoration is crucial for achieving long-lasting results. While sanding may seem like a straightforward option, crushed glass blasting offers superior benefits that can enhance the durability and beauty of your wood surfaces. With its eco-friendly profile and effective preparation capabilities, it’s a method worth considering for your next restoration project.
