What is hook and loop fixing?
Hook-and-loop sandpaper has a backing made of a material similar to Velcro.
It has hooks and loops that are used to attach the sandpaper to a machine such as a random orbital sander or disc sander.
The pads have small plastic “hooks” that attach to the “loops” on the sanding discs..
What causes swirl marks when sanding?
If you are talking about the occasional very noticeable swirl mark, most likely there was something that got stuck between the sandpaper and the wood. A stray piece of grit or a larger bit of dust. You have to move the sander slowly. Any fast movements can cause noticeable swirl marks.
Which way do you sand end grain?
So if you sand the side grain to 150, sand the end grain to 220; if the side is 220, the end and edge grains should be 320 and so forth. This makes the uniform roughness (which is really what sandpaper accomplishes) of the end grain smaller, where it soaks up less finish. Try it on your next project. You’ll be amazed.
Does sandpaper get dull?
Most little grains of sandpaper start with sharp edges and they slowly get dull. Garnet grits work differently: rather than wear off, they break off, leaving a new sharp little grit. So Garnet paper doesn’t get dull slowly, it sands very well right until there is no more grit.
How long do sanding belts last?
The abrasives we sell at Pete’s have very distinct lifespans; drum sander belts should last between 250 and 300 square feet each and edger discs should be changed every 20 linear feet.
Why won’t my sandpaper stick to my sander?
The simple fix for sandpaper that isn’t sticking is to replace the sander pad. … The problem might be with your sander, not the sandpaper. Orbital sander pads wear out with use. Eventually, the pad will need to be replaced no matter if you have Bosch, Makita, DeWALT or Porter-Cable sander like me.
Can you sand too much?
IMO – yes it can be sanded to much. I used to sand to 220 with a ROS until I made a nightstand out of White Oak and it would not hardly take a stain. Now with Red or White Oak I stop at 180 with a ROS and it seems to take a stain better and still has a nice finish.
Why does my sandpaper keep falling off?
The reason sandpaper is coming off your sander is that the current sander pad is worn out, replace the pad to fix the problem. Orbital sander pads wear out from regular use, eventually, the hook and loop Velcro will not properly hold onto your sanding discs.
Are you supposed to sand with the grain?
Sanding cross-grain tears the wood fibers so the sanding scratches show up much more, especially under a stain. The best policy is to always sand in the direction of the grain when possible. The scratching that does occur is then more likely to be disguised by the grain of the wood.
How long does a piece of sandpaper last?
A sheet of sandpaper may last months if you are only using it to do touch ups on a small 1095 blade but if you are reprofiling S110V that same sheet of sandpaper may only last an hour.
How do you know when sandpaper is worn out?
The easiest way to tell when it’s time to change the sandpaper is to run your finger lightly over the part of the paper you’ve been using, and do the same over a part that is still new – the part that is wrapped around a sanding block, for example.)
When should you stop sanding?
Typically you will want to stop at 180 or 220 if you are planning to stain the wood. Higher grits will close the pores of the wood and make it difficult for stain to penetrate. Go with the grain. Sanding cross-grain tears the wood fibers so sanding scratches show up more, especially on stained wood.
