Planing is a woodworking technique used to smooth the surface of wood or to reduce its thickness to achieve a desired thickness. It is commonly used to create more uniform and aesthetically pleasing finishes. However, there may be instances where treated wood requires planing, such as when you need to adjust the size or thickness of treated wood boards to meet specific requirements for a project.
Factors to Consider
While planing treated wood can be done, there are certain factors to consider before proceeding.
1. Safety Precautions:
Planing treated wood can release potentially harmful chemical residue that may be present in the wood due to the pressure treatment process. Therefore, it is essential to wear proper protective gear, such as a respirator mask, gloves, and safety goggles, to minimize exposure.
2. Chemicals in the Wood:
The chemicals used in the pressure treatment process can be corrosive to cutting tools or blades. It is crucial to ensure that your planer is equipped with blades made from materials that can withstand the chemicals present in treated wood. Using regular blades can result in damage to the planer or reduced lifespan of the blades.
3. Wood Moisture Content:
Treated wood is often infused with moisture during the treatment process, which can lead to warping or decay if not dried properly. Before planing treated wood, it is important to measure the moisture content using a moisture meter. The moisture content should ideally be below 15% to prevent problems in the future.
4. Hazards and Clean-up:
The chips and dust generated during planing treated wood can also pose a risk if not handled properly. The residue may contain chemicals, so it is crucial to dispose of it in accordance with local regulations and avoid contact with skin or inhaling the particles.
Planing Techniques for Treated Wood
When planing treated wood, it is recommended to follow these techniques to ensure optimal results:
1. Use Sharp Blades:
As mentioned earlier, the chemicals in treated wood can be harsh on cutting blades. Using sharp blades will minimize the strain on the tool and allow for efficient planing.
2. Take Smaller Passes:
To prevent excessive strain on the planer and blades, take smaller passes when planing treated wood. This will produce smoother cuts and reduce the chance of the wood becoming damaged.
3. Frequent Cleaning:
To prevent buildup of residue and chemicals, clean the blades, planer, and work area frequently during the planing process. This will help maintain the efficiency of the planer and produce better results.
While planing treated wood is possible, it requires some additional considerations and precautions. The chemicals infused in the wood, safety concerns, proper blade selection, and moisture content are all factors that should be taken into account. By following recommended techniques and taking safety precautions, planing treated wood can be done effectively, allowing for the desired adjustments to be made while ensuring the longevity and resistance to decay that treated wood offers.
