Sanding between coats of polyurethane is a crucial step to achieving a smooth and even finish. An orbital sander can be used, but it is important to use the right grit sandpaper and to clean off any dust before applying the next coat.
Finish Shrinking
Proper sanding is essential when applying multiple coats of polyurethane finish on a wooden surface. Over time, the finish on the surface will start to shrink and contract. Without sanding between each layer of polyurethane, the surface’s decreased size could cause the applied finish to break, crack or even peel off. Sanding ensures a smooth surface and eliminates uneven spots and rough patches before applying the additional coats.Solvents In Finishes
Solvents are chemicals in finishes that evaporate when exposed to air. Solvents help the finish to dry and harden. However, if you apply a new coat of polyurethane without sanding between coats, the solvents from the new coat will dissolve the underlying coat and compromise the finish’s adhesion. Sanding between coats allows the newly applied polyurethane coat to penetrate the existing coat without dissolving it, resulting in a robust and lasting finish.Oil-based Polyurethane Curing Process
Oil-based polyurethane curing process, unlike water-based, has a longer recoat window; however, it will require several coats and proper curing time to attain a durable finish. Sanding between each coat of oil-based polyurethane finish is essential to activate the curing process. The newly applied coat will bond more firmly with the existing dried coat, resulting in a smoother, more durable finish.Using Orbital Sander Vs. Hand Sanding
Using an orbital sander between coats of polyurethane instead of hand sanding speeds up the sanding process without compromising quality. An orbital sander will provide a more even sanding action since it moves in a circular motion, creating less visible scratches and swirl marks than hand sanding. Using an orbital sander ensures a uniform surface texture between each coat of polyurethane for an exceptional, professional finish. In conclusion, sanding between coats of polyurethane is essential to attain a smooth, durable finish. With proper sanding between each coat, you’ll avoid finish shrinking, solvents in finishes, and achieve a better oil-based polyurethane curing process. When deciding to use an orbital sander or hand sanding, the orbital sander is the more efficient and preferred choice.Choosing The Right Grit
Using an orbital sander between coats of polyurethane is perfectly fine, as long as you use a fine-grit sandpaper such as 220 or higher. Sand lightly to remove any bumps or imperfections without removing too much of the previous coat.
