Sanding 101
 Before
applying paint, stain or sealant, sanding is an important
step. It will not only smooth the surface but also help the
product you’re applying to adhere properly.
The particles on sandpaper are made up of
sharp edges that cut wood the same way a saw blade does. "Grit"
is a reference to the number of abrasive particles per inch
of sandpaper. The lower the grit, the rougher the sandpaper
and conversely, the higher the grit number the smoother the
sandpaper.
Sandpaper typically ranges from very coarse
to very fine and each is used for different purposes:
| Grit |

You’ll find Dynamic Sandpapers in
appropriate grits for any and every project! The best approach
to sanding is to begin with a lower grit, or coarser paper,
and increase the fineness of the sandpaper until desired results
are achieved.
Once all patching compound and caulking
has dried completely you're ready to sand to prepare the surface
for paint or stain. Dynamic's sandpaper and sanding sponges
come in a variety of grades and grits as well as being available
in a wide variety of types and sizes for virtually any sanding
need. Begin with 120 -180 grit for initial sanding, followed
by a 220+ grit (which is very fine) to produce a smooth surface
ready for paint. Patches should be sanded so that they will
not be noticeable. Glossy finishes should be lightly sanded
so that new paint can adhere.
 Once
sanding is complete, wipe all surfaces carefully using a Dynamic
Tack cloth – this slightly sticky cloth removes all
dust and particles to ensure a smooth finish.
Sanding Safety!
When operating sanding tools, be sure to use:
• Dynamic Dust Masks to prevent breathing dust created
while sanding. They come in a variety of types to suit any
degree of protection needed.
• Dynamic Safety Goggles to protect eyes from dust or
larger particles that may become airborne.
