Most people are unsure which “grit” of sandpaper to use when sanding. Sandpaper “grit” relates to the number of abrasive particles per inch of sandpaper. The lower the grit the rougher the sandpaper and you guessed it…the higher the grit the smoother the sandpaper.
The project I’m currently working on is a laminate cabinet. Laminate is very slick and non-porous so you MUST sand it for the primer and paint to adhere to it. Laminate is a man-made product (usually plastic). You can prime and paint laminate but you CANNOT stain laminate, it’s not wood.
I recommend using 120-grit sandpaper on laminate. Sand lightly enough to roughen the surface but not enough to tear through or loosen the laminate. If you use an electric sander don’t stay in the same place too long or you will tear the laminate off and be left with a difference in texture. If you’re new to sanding I would recommend doing it by hand with a sanding block before jumping into using an electric sander. Remember to always, ALWAYS wear a mask when sanding! Those fine particles go everywhere and you don’t need to breathe that in.
Stay tuned…more to come on my laminate cabinet project.
