Grit size
The grit size of 220 sandpaper means that it has 220 individual particles of abrasive in every square inch. Large numbers signify the particle size is smaller. An extremely fine 220 grit is best to produce a smooth surface. The sandpaper texture feels somewhat fine to the fingertips compared to lower grits.
Abrasive material
This sandpaper can be made from aluminum oxide paper, silicon carbide paper, or garnet paper. Aluminum oxide paper is the most on hand and durable variety. It withstands wet or dry sanding. Silicon carbide paper is sharper and harder than aluminum oxide. It works on harder surfaces. Garnet paper sands more smoothly but wears faster. It is used mostly for wood.
Backing material
The back of 220 sandpaper sheets is usually wet/dry paper for the sheet version. These papers are made porous resin to hold the paper together, and water will not penetrate through. Sanding sponges typically use a flexible foam with paper glued to the surface. Sanding belts and discs have a backing fabric that is very strong and will not tear.
Size
Standard sheets of sanding paper are dimensionally 9 x 11 inches/230 x 280 millimeters. Larger 1/4 sheets and 36 sanding discs are available in varying sizes too. Sponges come in multiple shape designs, while sanding belts typically fit specific belt sanders. These sanding belts are generally 1/2 inch to 3 inches wide by 18 inches to 36 inches long.
Versatility
The Sand paper 220 grit is flexible and well-suited for use on a divergent type of surface. Metal, plastic, wood, and drywall all accept sanding to a smooth finish using this abrasive grade paper. This versatility allows one sanding sheet to accomplish multiple finishing tasks.
Water resistance
The silicon carbide 220 grit sandpaper sheets provide wet/dry usage because they resist moisture. When wet sanding, water keeps dust down while cooling the area of sanding to mitigate burning or damage. This is advantageous for delicate finish work.
Ease of use
Application of 220 sandpaper is easy due to its wide availability and adaptability to multiple hand and power sanding tools. Projects from paint removal to final wood finishing demand only require the attachment or grip of 220 grit sandpaper to achieve professional results.
Preparation of the surface
Clear the work surface of dust, debris, and existing finishes via a scraper for optimum results. Clean using a damp cloth or vacuum. The work area also needs to be set up, including moving furniture out of the area or covering the floor.
Installation on tools
For hand sanding, attach the sandpaper block by simply cutting the paper to size and clamping it into the block. Hand sanding sponges should be held directly against the work surface. For power sanders, affix the disc or belt to the sander with the proper fastening method for your sander. Power sanders may utilize adhesive backing, tie, and staples.
Sanding
Sand gently using the grain of the wood applying light even pressure across the paper. Avoid pressing down too firmly to prevent paper tearing or uneven surfaces. Let the sander and paper do the work. If hand sanding, rub in circular motions.
Monitoring progress
Periodically assess how much finish or material has been removed throughout. Wipe with a damp cloth to clear away dust and debris to visibly monitor. Switch to a finer grit if desired.
Finishing up
Stop once the desired texture is achieved. Removal of dust after sanding is crucial. Completion of smooth finishes is accomplished by wiping a damp cloth or towel to remove all sanding dust completely before applying stain, sealer, or paint.
Smoother finishes
When sanding prior to painting or applying a finish, using 220 grit sand paper allows the woodworker to achieve smoother results.
