Refinishing a chair involves more than just slapping on a coat of paint—it’s about the details. Knowing how to sand between chair spindles can seem challenging.
However, with the right tools and technique, you can achieve a smooth, professional finish. Here’s how to do it, step by step.
Things You’ll Need
Here are the things you’ll need to sand your chair…
Drop Cloths or Newspapers: To protect the work area from dust and spills.
Medium-Grit Sandpaper (around 120-grit): For initial sanding to remove old finish and smooth rough areas.
Fine-Grit Sandpaper (around 220-grit): For final sanding to achieve a smooth finish.
Dowel Rod or Similar Tool: For wrapping sandpaper around and reaching tight spaces.
Tack Cloth or Damp Rag: For cleaning up dust after sanding.
Safety Equipment: Gloves, mask, and safety glasses for protection.
Stain, Paint, or Sealant (Optional): Depending on the desired finish.
Paintbrushes or Rags: For applying stain or paint.
Varnish or Lacquer (Optional): For sealing and protecting the finished chair.
1. Prepare Your Chair and Work Area
It’s crucial to begin by arranging your workspace in an area that allows for good air circulation, with a strong preference for outdoor settings. This is to ensure that any dust or chemical fumes generated during the process are effectively dispersed.
Begin by thoroughly cleaning your chair to eliminate any surface dust, dirt, or particles that could interfere with the refinishing process. Use a damp clot if necessary, but ensure the chair is completely dry before proceeding.
Position the chair on a stable, level surface. This could be a workbench or a drop cloth laid out on the ground. The height at which you place the chair should be comfortable for working without straining your back or arms.
If you’re working indoors, make sure to cover surrounding areas with drop cloths or newspapers to protect them from dust and any refinishing materials you’ll use later.
2. Choose the Right Sandpaper
Select medium-grit sandpaper (around 120-grit) to start the sanding process. You’ll switch to fine-grit (around 220-grit) later to smooth out the surface.
3. Wrap Sandpaper Around a Dowel
To effectively sand hard-to-reach areas, such as between spindles or in tight corners, cutting your sandpaper into manageable strips is a practical approach. Choose a width that comfortably wraps around a dowel rod or a tool of similar diameter.
The dowel rod acts as a sanding block, giving you greater control and leverage when sanding intricate parts of the chair. This technique is particularly useful for achieving a uniform finish in areas where using your fingers directly might apply uneven pressure or fail to reach.
When wrapping the sandpaper around the dowel, ensure it is snug but not overly tight. This allows the sandpaper to conform to the shape of the dowel, providing a firm and stable sanding surface.
Secure the ends of the sandpaper strip to the dowel, if necessary, with a small piece of tape. This prevents the sandpaper from shifting or unwrapping during the sanding process.
4. Sanding Motion
When using the dowel wrapped in sandpaper, employ a systematic back-and-forth motion along the length of the spindles. This methodical approach ensures that all areas of the spindle receive equal attention, resulting in a uniformly smooth surface.
Start from the top of the spindle and gradually work your way down, maintaining a consistent rhythm in your sanding motion.
This top-down approach not only helps in keeping track of the areas you’ve already sanded but also allows for any dislodged dust or debris to fall naturally away from the unsanded areas.
Applying even pressure throughout the sanding process is key. Too much pressure can lead to uneven sanding and potential damage to the wood, while too little pressure may not effectively remove the old finish or smooth out the wood grain.
The goal is to use just enough pressure to achieve effective sanding without causing indentations or unnecessary wear to the wood.
It’s important to sand all sides of each spindle comprehensively. Rotate the spindle as needed to access all areas, ensuring that no side is left unsanded.
This is crucial for achieving a balanced finish and preparing the spindles for subsequent treatments, such as staining or painting. Pay special attention to any intricate designs or carvings on the spindles, as these areas might require more detailed work to reach all the nooks and crannies.
After sanding each spindle, take a moment to feel the surface with your fingers. This tactile inspection can help detect any remaining rough spots or missed areas that might not be visually apparent.
Repeat the sanding motion on these areas until the entire spindle feels uniformly smooth to the touch. Remember, the quality of your sanding at this stage will greatly influence the final appearance and finish of your chair.
5. Switch to Fine-Grit Sandpaper
Transitioning to fine-grit sandpaper is a critical step in achieving a professionally smooth finish on your chair. After you have successfully removed the old finish and addressed any imperfections with the medium-grit sandpaper, it’s time to refine your work.
Switch to a fine-grit sandpaper, typically around 220-grit, which is designed to smooth the wood to a finer degree. This finer grit effectively eliminates any minor scratches or roughness left by the medium-grit sandpaper, preparing the wood for finishing touches like staining or painting.
When repeating the sanding process with the fine-grit sandpaper, continue to use the same methodical back-and-forth motion along the grain of the wood.
This ensures that you maintain the natural pattern of the wood while achieving a smooth surface. Apply gentle, even pressure to avoid creating new scratches.
The goal here is to refine the surface, not to remove more material. Pay special attention to areas where the medium-grit sandpaper may have left noticeable marks.
As you work with the fine-grit sandpaper, you will notice the wood becoming increasingly smoother. It’s important to periodically check the feel of the surface with your hand.
The wood should feel consistently smooth across all areas. Be diligent in sanding every part of the chair, including hard-to-reach spots and edges. This uniform smoothness is essential for a quality finish.
Remember to regularly clean the dust off the sandpaper to maintain its effectiveness. Once the entire chair has been sanded with the fine-grit paper, it should have a noticeably smoother feel compared to after the medium-grit sanding.
This level of smoothness is vital for a high-quality finish, as it allows stains, paints, or sealants to adhere better and more evenly, resulting in a more professional and aesthetically pleasing final product.
6. Clean Up
Once the sanding process is complete, it’s essential to thoroughly clean the spindles to remove all traces of sanding dust. This step is crucial as any remaining dust can interfere with the application of finishes such as paint, stain, or sealant.
Begin by using a tack cloth, which is specially designed to pick up and hold dust particles. Gently wipe the surface of each spindle with the tack cloth, ensuring that you reach into all crevices and around any intricate details. The tack cloth’s sticky surface efficiently captures even the finest dust particles.
If a tack cloth is not available, a slightly damp rag can be an effective alternative. The dampness of the rag helps to collect the dust without leaving any moisture residue on the wood.
Wipe each spindle carefully, turning or folding the rag frequently to ensure a clean surface is always in contact with the wood. Be careful not to saturate the wood with too much water, as this can raise the grain and undo some of your sanding work.
After wiping down the spindles, take a moment to inspect the chair as a whole. If there’s any accumulated dust on other parts of the chair or the surrounding work area, clean it up as well to maintain a tidy and efficient workspace.
7. Finishing Touches
With the spindles sanded and cleaned, you are now ready to apply the finishing touches. Whether you choose to stain, paint, or apply a sealant, ensure that you follow the manufacturer’s instructions for the best results.
These finishes not only enhance the aesthetic appeal of your chair but also provide protection to the wood.
If you’re using stain, apply it with a brush or a clean rag, working it into the wood in the direction of the grain. Wipe away any excess stain to avoid uneven coloring or blotches.
For painting, select a brush or roller suitable for the type of paint you’re using and apply evenly, taking care to avoid drips or streaks. Sealants, like varnishes or lacquers, should be applied in thin, even coats, allowing sufficient drying time between coats as recommended by the manufacturer.
Each type of finish requires a different technique and attention to detail. Always work in a well-ventilated area and take appropriate safety precautions, such as wearing gloves and a mask if needed.
Allow the finish to dry completely according to the product’s guidelines before using or handling the chair. This patience ensures a durable and attractive finish that will protect your chair for years to come.
