Just about every home project involves sandpaper. Doing a good job with it can
make the difference between a professional-looking product and an amateur job.
Step 1: Select the right abrasive paper for the job. There are five general
- Wet & Dry grey-black coloured for fine finishing hard surfaces like
metals, glass, plastic, concrete and timber.
- Emery paper or cloth deep maroon coloured for cleaning and finishing
- Non-clog aluminium oxide paper white coloured for dry sanding painting
surfaces. Designed for sanding between coats of paint or lacquer without
clogging the paper.
- Glass paper brown-yellow coloured general clean up and sanding wood.
- Garnet paper orange coloured finishing of all types of unpainted wood.
Step 2: Select the grade or grit. The lowest grit number is the coarsest, and
the highest is the finest. So 40 grit is used for removing lots of wood to
remove deep scratches or machine marks, while 240 grit will smooth the surface
ready for painting.
Always sand with the grain (not across). This will avoid scratch marks.
Sandpaper is also available in rolls just dont hang them next to the dunny.
Theres lots of information on the back of the sandpaper packs. Take the time to
read it, maybe when youre sitting down.
Sandpaper from FH Prager is available at all leading hardware stores.
