Wood dust from sanding will cause problems if it’s not removed from the surface before staining. Dry rags or brushes aren’t the most effective tools for removing dust. Instead, use a tack cloth, a sticky piece of cheesecloth made especially for this purpose. Wipe the folded tack cloth across the wood to remove dust. As each side becomes saturated with dust, refold the cloth to expose a fresh surface.
We cannot stress enough that you must have a strong base of proper sanding to achieve the perfect finish!! See our sanding tutorial below if you want more details. All surfaces should be clean and free from all dirt and oils.
Backing for sandpaper includes paper, cotton, polyester, rayon, PET film and rubber. Mylar is used as backing for extremely fine grits. Micro grit-sized sandpapers are commonly used on wood and some on drywall. The grit of sandpapers is a rating of the size of abrasive materials on the sandpaper.
I’ll have to pick up some Granat – have not used it yet. As cost was important, Rubin is the first to drop off the list. I myself prefer your advice, because that’s the way to get the best result, and the way I do it, but from a cost perspective Rubin is not the best choice.
For wetting the wood, use mineral spirits or denatured alcohol. Avoid mineral spirits if you are going to apply a water-based finish because any oily residue from the thinner might cause the finish to bead up. Denatured alcohol will raise the grain a little, so you’ll have to sand it smooth again. Being sure that these flaws and scratches are removed is the reason most of us sand more than we need to. The most efficient use of sandpaper for hand-backed sanding is to tear the 9″ x 11″ sheet of sandpaper into thirds crossways, then fold each of these pieces into thirds lengthways.
I recently purchased a Festool ETS125, I found that it wasn’t performing very well so I exchanged it for a new one. This new one is the same way, after watching your 150 spinning like crazy I know that what mine https://ronbaileyscarvings.com/sandpaper-for-woodworking/ is doing is not right, any ideas? I have tried all variations of grit, wood and I have the vacuum turned down low. Informative and helpful video Marc but I have a beef with Festool and their naming system.
Use it as you would any other abrasive by keeping it moving. The abrasive continues to cut as the grit breaks down into smaller silica particles in use, leaving a silky smooth surface. For most applications, a good ratio of weight, flexibility and flatness are crucial for abrasive product performance. This is popular in light metal finishing applications and knife handle work. Y wgt is typically used for heavy duty applications. Cloth materials are stiffer and used in most belt sanding applications due to their increased strength.
To remove those last bits of finish, palm sand with medium sandpaper until you see the bare wood. Then switch to fine sandpaper (200+ grit) until the entire piece is uniform. Wipe down the whole surface with a tack cloth to remove any dust from sanding.
Just take it slow, never let the sander hang more than half way over the edge, and overlap your passes and you progress from one side to the other. One thing often missed is the speed, https://ronbaileyscarvings.com/ generally the courser the grit the slower speed I’ll use , and the finer the grit the faster the speed you can use. Thanks for the great video, it comes just in time for me.
I hadn’t though about the cross-contamination of sanded particles before; thanks for the heads up. Man, I danced all around it between each grit looking for issues. You would have thought I was working on a master piece. As you can see in this video, I’m using the ETS150 for everything.
I saw a video of Charles Neil where he used a 1200 silicon carbide sanding disc with soapy water as a lubricant. Do you think it will cut too aggressively, or should I just give it a try. I always thought you needed to wait until the very last to raise the grain and smooth it out with one last quick sanding. It really does help make sure you are using each grit for a long enough period of time. You could certainly wet the surface with a little mineral spirits to see if you notice any major scratches, but i am usually not let down by the pencil method.
