Coarse grits (those under # 100 ) damage a fine wood finish. Medium grits, such as # 120 and # 150 , are useful for removing old finish or scratches. Fine grits, such as # 220 , are frequently used for a final light sanding just before applying stain to the wood.
I used a variety of 100 – 220 grit sandpaper to do my distressing , and it helped to have a hand sander or sanding sponge to wrap the sandpaper around. It gave me a little more to grip. The general rule when distressing is to sand on sections that would naturally receive wear and tear over time: corners.
Generally speaking, 30- grit and 60- grit papers are used for rough sanding, 100- grit to 150- grit sandpaper is for medium sanding, and 220 – grit sandpaper is used for finish sanding. Of course, this changes with the type of wood and whether the sanding is done by hand or with a machine.
As with any paint job, clean the surface well before beginning (and if you ‘re not sure which method to use, test a few in small patches before committing to the whole job).
7000 Grit in Wet and Dry Sandpaper Sheets These sheets have a silicon carbide grain and a strong A-weight latex paper backing with high tear resistance. They are ideal for wet or dry sanding of primer, putty, filler and lacquer with the soaked material having excellent flexibility.
Stripping is Faster and Often Safer. It’s almost always better to strip than to sand . To begin with, except in cases where the old finish is flaking off, it’s a lot more work to sand than to strip using a paint-and-varnish remover.
Steps: Lightly sand the object you want to distress . Paint the entire piece in the base coat color you’ve selected. For the bare-wood look : When the base coat is dry, start sanding off areas that would naturally end up distressed — places where hands would have held it, or corners that could easily get nicked.
When you distress your furniture after you apply your initial coat of wax , you don’t want to wait a day or two to do so. You will have an easier time of it if you distress immediately after you paint and wax … before the paint has had a chance to thoroughly dry and begin its curing process.
Macro Grit Sandpaper
|Very Fine||A coarser material than Very Fine under the micro abrasives||150, 180 or 220|
|Fine||Cannot remove varnish or paint on wood||100 or 120|
|Medium||Medium to coarse surface texture after sanding||80|
|Coarse||Has the ability to remove material rapidly||40, 50 or 60|
For heavy sanding and stripping, you need coarse sandpaper measuring 40- to 60- grit ; for smoothing surfaces and removing small imperfections, choose 80- to 120 – grit sandpaper . For finishing surfaces smoothly, use a super fine sandpaper with 360- to 600- grit .
Fine sandpapers range from 120- to 220 – grit . Extra fine sandpaper is often used between coats of paint or varnish. Grits of 240, 320 and 400 are termed very fine , while extra- or superfine sheets with grits of up to 600 are best-suited for polishing jobs.
When You Can Skip Sanding , Deglossing and Priming If the finish on your furniture isn’t damaged or chipping, it’s flat not shiny and you aren’t painting it a drastically different color, then you may be able to just go ahead and start painting . Before painting though, do make sure the piece is clean.
As it turns out, not only can you spray paint wood without sanding – you can also spray paint pressed wood /particle board (which some parts of this desk were) and even that papery cardboard panel on the back. All of it you guys. Just spray paint ALL of it. Then let it dry and do it again.
A lot of folks make the mistake of sanding to either too fine of a grit or not fine enough before applying stain . Too fine and the wood won’t be able to accept the stain . Too rough and the wood will be very dark almost to the point of being black.
