Getting More Life Out of Sandpaper

Post by Nitcat on June 26th 2009, 8:31 am

Maybe this is a no-brainer, but I discovered it myself and thought I'd ask if others do this.

Even when you keep your sandpaper wet, the paint being removed tends to gum up the paper. I would have that happen and after the paper got full of paint I would start with another piece of paper.

Now I've been using a green scrubby pad to rub the paint out of my paper and the paper is lasting a lot longer. Basically after I've wet sanded a couple square feet, I'll wet the paper in a bucket of warm water and scrub the paper with a couple swipes of the green pad. It takes the paint off well and the paper is ready to go again.

another trick is to add a few drops of dish soap to your bucket of water. This keeps the paper from loading up and helps keep it from "sticking" when sanding.
When wet sanding primer I use the green scotch brite pads. Never use them on paint but for primer they seem to work good.

If your paper is clogging during wetsanding, you aren't "dipping" the paper often enough..Keep a bucket full of water with you, dip the paper, wet your hand and wipe your wet hand over the approx. one square foot area you are working. Working an area any bigger at any one time can get counter productive.

Another thing you can do is keep a hose trickeling water over the area you are sanding. That also helps to keep it clean.

I would tie an old tee shirt to the end of the garden hose, set the hose on the car and let the water slowly run down the panel I was sanding.

I hold my hose with a mist head in one hand, and sand with the other, running water constantly. I used to use a spray bottle and spray constantly, but then I end up with 2 tired hands.. Razz

You can hose off the sandpaper easily that way too

Another way to reduce clogs is to rub the sandpaper with another piece of sandpaper.

I love the idea of just running a hose, but I'm working in a garage... ...no floor drain... wouldn't work too well for too long Suspect
