Proper Sanding Techniques
To start, maintain a consistent speed when using the sander. A slower pace affords better control, while moving too fast might miss spots. It’s essential to keep the sander flat against the surface to avoid gouging the wood. Instead of applying excessive pressure, let the sander do the work. Always sand in the direction of the wood grain for best results.
Moreover, before you begin, make sure to use the proper grit sandpaper. Start with a lower grit, such as 60 or 80, to remove old finishes or rough spots. Transition to a higher grit, like 120 or 150, to achieve a smooth finish. Switching grits ensures that the wood's surface is well-prepared for any sealant or stain you may apply later.
Achieving a Consistent Finish
Achieving a consistent finish requires a combination of technique and attention to detail. First, overlap your sanding passes by about half the diameter of the sanding pad. This method helps to avoid streaks or missed spots that can happen with a more scattershot approach. The goal is to create uniformity in texture and depth.
It’s advisable to change out the sanding disk when it shows signs of wear. A worn disk cannot effectively sand the wood, resulting in uneven surfaces. Also, regularly check the surface for areas that may require extra attention. If you notice any uneven spots, focus your efforts there until the surface appears uniform.
"Attention to detail during sanding often determines the final quality of your deck's look."
