Hi All

Plan B

My lazy susan is ruined. Ended up with a big hole in it. Guess a small box
will do as a send away gift.

Question?

What are the proper techniques for water sanding. EG. Type of sandpaper and
how to use it etc?

There are three techniques, wet sanding, grain raising, and grain
filling.

Wet sanding is for sanding hard surfaces that result in a fine powder
(i.e. film finishes, metals); the water helps clean the sandpaper and
wash away the powder so that the sanding can proceed without clogging
up. For this technique, you'd want the item wet while sanding, either
by rinsing it, running water over it, or rinsing the paper
occasionally. You need a waterproof sandpaper for this, I usually use
sillcon carbide wet/dry sandpaper.

Grain raising is different. If you have unfinished wood, what you do
is rinse the wood and let it dry, then sand off the raised grain.
Repeat with finer and finer grits as usual. The result is that you
have a piece that, if it happens to get wet (washing or water-based
finishes), won't get that fuzzy feel. In this case, any sandpaper
will do, and you'd use compressed air or a tack cloth to remove the
powder.

The third case is grain filling, or wet sanding with a finish. This
is for grain filling, such as a french polish. What you do here is
use a wet/dry paper with an oil (instead of water), so that as you
sand the powder gets trapped in the grain with the oil, and dries that
way, filling the grain.

Keith,
Your best source for this will probably be an auto paint supply store or big
box store that sells auto painting supplies. You will need at leqst wet/dry
paper (silicone carbide) 600 grit, with better results obtained by going to
1000 grit. If you know any painit and body workers, stop by and watch them
work the final coats of their paint jobs, especially if they're doing clear
coat finish. That will be very similar to what you'll want to do. Good luck.
