Refinishing a wood table requires selecting the right grit sandpaper to achieve a smooth, professional finish. The process typically begins with a coarse grit, such as 80 or 100, to remove old paint, varnish, or stains, and to smooth out any rough surfaces or imperfections. As the wood becomes more refined, transitioning to medium grits like 120 or 150 helps eliminate scratches left by the coarser paper and prepares the surface for finishing. Finally, fine grits such as 180 or 220 are used to create a polished, ready-to-finish surface, ensuring the wood is smooth to the touch and ready for staining, sealing, or painting. Choosing the correct sequence of grits is essential for restoring the table’s natural beauty and ensuring a durable, long-lasting result.

Choosing Grit Sequence: Start coarse (60-80 grit), progress to medium (120-150), finish fine (220+)
Refinishing a wood table requires a deliberate grit sequence to balance efficiency and precision. Begin with coarse grit sandpaper (60-80 grit) to strip old finishes, smooth deep scratches, and level uneven surfaces. This aggressive grit removes material quickly but leaves noticeable scratches, which is acceptable at this stage since finer grits will follow. Use a belt sander or orbital sander for large, flat surfaces to save time and effort. Avoid lingering in one spot to prevent gouging the wood.
Progressing to medium grit (120-150) refines the surface while minimizing the coarse scratches left behind. This stage is about blending and smoothing, not removal. Hand-sanding with a sanding block ensures even pressure and control, especially on edges or curves. Work in the direction of the wood grain to avoid splintering. After sanding, wipe the surface with a tack cloth to remove dust, which helps assess progress and ensures the next grit isn’t clogged with debris.
The final stage with fine grit (220+ grit) polishes the wood to a smooth, touchable finish. This grit eliminates all visible scratches, preparing the surface for stain, paint, or sealant. Use an orbital sander for large areas and hand-sand delicate spots. Finish by wiping the surface again with a tack cloth and inspecting under bright light to ensure uniformity. Skipping this step risks a rough finish that undermines the refinishing effort.
Choosing the right grit sequence isn’t just about progression—it’s about understanding the wood’s condition and your goals. For heavily damaged tables, start with 60 grit; for lighter wear, 80 grit may suffice. Similarly, if the wood is soft (e.g., pine), avoid over-sanding with fine grit, as it can close the grain and affect absorption of finishes. Always test a small area first to gauge the wood’s response to each grit.
Practical tips: Label sandpaper sheets with their grit to avoid confusion, especially when switching between stages. For intricate details or tight spaces, fold a piece of fine grit sandpaper into a small, sharp edge to reach corners without damaging the wood. Finally, invest in high-quality sandpaper—cheap options wear out quickly and leave inconsistent results. Following this grit sequence transforms a worn table into a smooth, ready-to-finish surface with professional-grade results.

Removing Old Finish: Use 60-80 grit to strip paint, varnish, or stains effectively
The first step in refinishing a wood table is often the most critical: removing the old finish. This process demands a balance between aggression and precision, as you aim to strip away layers of paint, varnish, or stains without damaging the wood beneath. For this task, 60-80 grit sandpaper emerges as the ideal tool. Its coarse texture is aggressive enough to break through stubborn finishes yet fine enough to avoid gouging the wood surface. This grit range is particularly effective for tables with multiple layers of old paint or heavily built-up varnish, where finer grits would merely skim the surface without achieving the desired result.
When using 60-80 grit sandpaper, technique matters as much as the tool itself. Begin by sanding in the direction of the wood grain to minimize scratches and maintain the wood’s natural texture. Apply firm, even pressure, but avoid excessive force, which can lead to uneven surfaces or wood damage. For intricate areas or curved edges, consider using a sanding block or folding the sandpaper to fit the contours of the table. Work systematically, starting with one section and moving across the entire surface to ensure consistency. Remember, the goal here is not to achieve a smooth finish but to remove the old layer entirely, preparing the wood for further refinishing steps.
One common mistake is rushing the process, which can lead to incomplete stripping or unnecessary wood removal. Take your time, especially if the finish is particularly stubborn. For tables with multiple layers of paint, you may need to switch sandpaper sheets frequently, as the grit clogs quickly. Keep a bucket of water nearby to clean the paper periodically, extending its lifespan and maintaining effectiveness. If the finish is extremely thick or resistant, consider using a chemical stripper in conjunction with sanding, though this adds extra steps and requires careful handling of chemicals.
The choice of 60-80 grit is not arbitrary; it strikes a practical balance for most refinishing projects. Finer grits, such as 100 or 120, lack the cutting power needed for heavy-duty stripping, while coarser grits like 40 can be overly aggressive, risking damage to the wood. By starting with 60-80 grit, you efficiently remove the old finish while leaving a surface rough enough for subsequent sanding with finer grits. This staged approach ensures a smooth, even base for staining, sealing, or painting, ultimately enhancing the final appearance of the table.
In conclusion, 60-80 grit sandpaper is the unsung hero of the refinishing process, offering the perfect blend of power and control for stripping old finishes. Its effectiveness lies in its ability to tackle tough layers without compromising the wood’s integrity. By mastering its use—through proper technique, patience, and awareness of its limitations—you set the stage for a successful refinishing project. Whether reviving a family heirloom or updating a flea market find, this grit range is your first step toward transforming a worn table into a stunning centerpiece.

Smoothing Bare Wood: Use 120-150 grit to level surfaces and remove imperfections after stripping
After stripping a wood table, the surface often reveals a landscape of imperfections: raised grain, stubborn residue, and uneven patches. This is where 120-150 grit sandpaper steps in as your first line of defense. Think of it as the bulldozer in your refinishing arsenal, designed to level the playing field before finer grits take over. This grit range strikes a balance between aggression and control, removing imperfections without gouging the wood. It’s the critical step that transforms a rough, stripped surface into a uniform canvas ready for further refinement.
The process is straightforward but demands attention to detail. Start by sanding in the direction of the wood grain, applying even pressure to avoid creating new dips or scratches. Work systematically, dividing the table into sections to ensure thorough coverage. For stubborn areas, like dried glue or deep scratches, focus on those spots with short, deliberate strokes. A power sander can expedite this stage, but hand sanding allows for better control, especially on curved or intricate areas. The goal is to achieve a consistently smooth surface, free of any tactile imperfections.
Choosing between 120 and 150 grit depends on the wood’s condition and your project’s timeline. If the surface is heavily marred or you’re working with a dense hardwood like oak, 120 grit’s coarser texture will save you time. For softer woods or surfaces with fewer flaws, 150 grit offers a slightly gentler approach while still delivering effective results. Whichever you choose, remember this grit is not about achieving a polished finish—it’s about creating a solid foundation for the next steps.
A common mistake at this stage is rushing or skipping to finer grits too soon. Doing so leaves behind imperfections that will become more pronounced under stain or finish. Take your time and test the surface with your hand frequently. When the wood feels uniformly smooth and free of snagging grain, you’re ready to progress to finer grits. This patience ensures the rest of the refinishing process goes smoothly, saving you from backtracking later.
In essence, 120-150 grit sandpaper is the unsung hero of wood table refinishing. It’s the step that bridges the gap between stripped chaos and refined elegance, setting the stage for a flawless final product. Master this stage, and you’ll find the remaining steps flow with far greater ease.

Final Sanding Before Finish: Use 220+ grit for a smooth, ready-to-finish surface
The final sanding stage is where your wood table transforms from a rough, uneven surface to a silky-smooth canvas ready for its finishing masterpiece. Here, the spotlight shines on 220-grit sandpaper and its finer counterparts. Think of it as the polishing step before the grand reveal.
Lower grits, like 80 or 120, are the heavy lifters, removing old finishes, smoothing out imperfections, and shaping the wood. But they leave behind scratches, like tiny trenches in a battlefield. 220-grit sandpaper steps in as the peacemaker, meticulously erasing these battle scars and creating a uniform surface that begs for a beautiful finish.
Imagine applying a glossy polyurethane directly onto a surface sanded with 120 grit. The result? A finish that highlights every scratch, resembling a topographical map more than a sleek tabletop. 220 grit, however, ensures a smooth foundation, allowing the finish to adhere evenly and reflect light beautifully, showcasing the wood's natural grain.
For optimal results, use a sanding block to maintain even pressure and prevent rounding over edges. Work with the grain, using long, smooth strokes. Remember, this is a finesse operation, not a brute-force attack. After sanding, thoroughly remove all dust with a tack cloth or damp microfiber cloth. Any leftover dust particles will become permanent blemishes under your finish.
While 220 grit is the standard for final sanding, consider going even finer for an ultra-smooth finish. 320 or 400 grit can be used for delicate woods or if you're aiming for a mirror-like sheen. However, be cautious: excessively fine grits can close the wood's pores, hindering proper finish absorption.

Hand vs. Machine Sanding: Hand sanding for control, machine sanding for efficiency on large areas
Refinishing a wood table requires careful consideration of sanding techniques to achieve a smooth, even surface. The choice between hand sanding and machine sanding hinges on the balance between precision and speed. Hand sanding offers unparalleled control, allowing you to navigate intricate details, edges, and curves without risking damage to the wood. For example, when smoothing out delicate carvings or tight corners, the tactile feedback of hand sanding ensures you apply just the right amount of pressure, preventing over-sanding or uneven results. However, this method is time-consuming, particularly for large, flat surfaces.
Machine sanding, on the other hand, excels in efficiency, making it ideal for expansive areas like tabletops. Power sanders, such as orbital or belt sanders, cover ground quickly and maintain consistent pressure, reducing the likelihood of visible scratches or swirl marks. For instance, starting with an 80-grit sandpaper on a machine can rapidly remove old finishes or rough patches, followed by 120-grit for smoothing, and 220-grit for final polishing. Yet, machines lack the finesse required for detailed work and can be unforgiving if mishandled, potentially gouging or overheating the wood.
A practical approach combines both methods. Begin with machine sanding to level the surface and remove bulk material, then transition to hand sanding for edges, corners, and final touches. This hybrid strategy maximizes efficiency while preserving the wood’s integrity. For example, use a random orbital sander with 100-grit paper to flatten the tabletop, then switch to hand sanding with 150-grit for edges and 220-grit for a silky-smooth finish. Always sand in the direction of the grain to avoid scratches and ensure a professional result.
Caution is essential when using machines, as aggressive sanding can irreparably damage the wood. Keep the sander moving to prevent heat buildup, and avoid lingering in one spot. Conversely, hand sanding requires patience and attention to detail, especially when transitioning between grits. A tip for hand sanding: wrap the sandpaper around a block for even pressure and smoother results. Ultimately, the choice between hand and machine sanding depends on the project’s demands—control for precision, efficiency for scale. By mastering both techniques, you’ll achieve a flawlessly refinished wood table tailored to its unique characteristics.
