Frequently Asked Questions
Should I use an orbital sander or a belt sander for my deck?
A belt sander is a workhorse designed for aggressive material removal, which is perfect for decks with thick, peeling paint. If your deck just needs a light smoothing before a new coat of stain, an orbital sander is much easier to control and less likely to leave deep gouges in the wood.
How much of the old stain do I need to remove?
You only need to remove the finish that is currently failing, such as areas that are peeling, flaking, or bubbling. If the existing stain is still firmly bonded to the wood, you can simply scuff-sand the surface to help the new finish adhere. Do not waste energy sanding down to bare wood unless the current finish is truly ruined.
What is the best grit sequence to follow?
Start with a coarse 40 or 60-grit paper to strip away the old finish and level out any uneven boards. Once the surface looks clean, switch to an 80 or 100-grit paper to smooth out the scratches from the first pass. Always finish with a light sanding to ensure the wood grain is open and ready to absorb the new stain.
Can I use a palm sander for a large deck?
You can, but your patience will be put to the test. Palm sanders have small motors and limited surface coverage, making them better suited for furniture or small deck railings. For the main floorboards, the efficiency of a larger orbital or belt sander is worth the extra cost.
How do I handle the gaps between the deck boards?
Avoid pushing the sander into the gaps, as this will round over the board edges and damage your sandpaper. It is much better to stop the sander an inch from the gap and use a handheld sanding block to finish the edges carefully. This ensures your deck boards stay crisp and professional looking for years to come.
