When it comes to refinishing or painting wood surfaces, sanding between coats is often necessary to achieve a smooth and professional finish. Sanding between coats helps to remove any imperfections, bumps, or rough spots that may have developed during the previous coat of paint or finish. But what grit sandpaper should you use between coats? Let's take a closer look.
The grit of sandpaper refers to the number of abrasive particles per square inch on the paper. The higher the number, the finer the grit. When sanding between coats, it's important to use fine-grit sandpaper to avoid removing too much of the previous coat and to prevent creating scratches or other marks that will show up in the final finish. Generally, a grit of 220 or higher is recommended for sanding between coats.
Using too coarse of grit can be counterproductive and may result in uneven surfaces or scratches that will show through in the final finish. It's also essential to ensure that the surface is completely clean and dry before sanding between coats to prevent any debris or dust from getting trapped in the new coat of paint or finish.
When sanding between coats, it's important to use a light touch and to rub in the direction of the grain. This will help avoid creating new scratches or marks on the surface. After sanding, be sure to wipe the surface with a clean, dry cloth to remove any dust or debris before applying the next coat.
In conclusion, when sanding between coats, it's best to use a fine-grit sandpaper of 220 or higher to avoid removing too much of the previous coat or creating new scratches. Always sand in the direction of the grain and use a light touch. With proper sanding techniques, you can achieve a smooth and professional finish on your wood surfaces.
