The Basics Of Sanding Wood Flooring

Continue until you get a light “slurry” of sawdust and oil. That’s because the grain of the wood swells up when it comes into contact with moisture. The grain raises leaving the surface of the primed or painted wood feeling really rough. This is why you also have to sand between every coat of paint as it will smooth out the raised grain and remove any imperfections before you apply the next layer of paint. Deciding which grit sandpaper is best for your project isn’t as difficult as you think.

My favorite way to remove the sawdust is to use a soft bristled brush to sweep off the bulk of the sawdust. Then, I wipe down the wood with tack cloth to remove the remaining saw dust. Tack cloth is sticky so I like to wear latex gloves when cutting and handling it, but it works great for removing any remaining saw dust and you don’t need to use a lot of it. Note, if I am using a premium wood for my project that is in really good condition to begin with, then I will typically just first use 120 and then 220 grit only. But, if my wood is really rough to begin with or has a lot of an old finish on it, I will start with 60 grit sandpaper and move up in the grit number from there. I highly recommend an orbital palm sander for most wood projects, which is a very efficient and affordable sanding tool.

Tips And Tricks For Sanding Wood

Like the air in your work area, both the wood surface and any wood preparation product you are using should be above 65° F. Let them sit at room temperature overnight before starting your wood project. When using oil-based conditioner, allow it to penetrate into the wood for 5-15 minutes. Then be sure to remove any excess with a clean, dry cloth. Small holes and cracks in the wood can be filled using Minwax® Stainable Wood Filler.

Take Safety Precautions Before You Start Sanding

• Sand in the direction of your machine’s aggressive cutting side. You should know whether the sanding surface of the machine is set up to cut from the right or the left. If the machine is set up to cut aggressively on the right side of the drum, begin sanding on the left wall and move right. If the machine is set upto cut aggressively on the left side of the drum, begin sanding on the right wall and move left.

Since I only use finishes based on linseed-oil I’ve to reach the targeted smoothness before applying the oil. Even after weeks of drying you’ll ruin your sandpaper with the first stroke on the stuff. I have heard a few times from other turners that the finish will only be as good as the surface you put it on. That could be totally wrong but I find it very difficult to not sand until it is perfect.
