What You Need to Know About Sanding Down Plastic (1)

Sanding plastic is tricky, and comes with a list ofpotential problems. But majority of times, heat is the largest issue you willface. Common knowledge tells us that friction creates heat, so it should be nosurprise that sanding produces heat. Unlike wood and metal that warm up butthen reflect heat, plastic absorbs heat; so even the smallest amount of heatcan soften, warp, crinkle, or alter plastic, thus jeopardizing the finaloutcome of your project.

But all this does not mean that it is bad to sand plastic.Sanding plastic increases surface area, which creates even more opportunity fornew coatings to adhere to the surface. A simple “gentle scuffing” or lightsanding is enough to improve on adhesion. It doubles surface area, givingcoatings new areas to cling to!

A gentle sanding is fine for plastic, but too much cancreate a load of problems. For instance, a common problem caused by too muchsanding of plastic is a defect called hairing, in which parts of plasticsplit off into hair-like strands. It can also called thermoplastic re-flow,blemishing, scratching, and much more. Use the proper sanding products and findthe right medium in terms of pressure, and you should be safe!
