What to Check Before Buying a Wall Sander
Choosing the right wall sander involves evaluating several key factors. Power is important: corded models generally offer more consistent power for heavy sanding, while cordless models provide portability. Dust collection is critical for health and cleanliness; look for models with built-in vacuum or bag systems. The size and shape of the sanding pad affect how quickly you can cover large areas versus reaching corners. Weight and ergonomics matter for comfort during extended use, especially for overhead work. Finally, consider the availability of replacement pads and the brand's reputation for reliability.
Mistakes to Avoid When Sanding Walls
One common mistake is using too coarse grit paper, which can leave deep scratches that require extra work to smooth out. Always start with a medium grit and progress to finer grits. Another error is neglecting dust extraction; drywall dust is harmful to breathe and can create a mess. Use a sander with a good dust collection system or connect to a shop vac. Overloading the sander with pressure can also cause uneven sanding and wear out the pad faster. Let the tool do the work with light, even pressure. Finally, failing to seal the wall before painting can lead to uneven absorption of paint, so always prime after sanding.
