Alternatives to sanding

Alternatives to sanding

Paint removal doesn't have to be done with a sander. Some alternatives:

Mesh grit wheel

This is a grit-impregnated coarse nylon wheel or disc that you attach to a drill or small angle grinder. It won't clog up like paper, and can be very useful for rapidly stripping paint from metal and other surfaces, especially on irregular shapes.

Not so good for large flat surfaces, such as walls.

Scraping

Possibly the best way to remove paint from around window and doorframes. Tungsten carbide scrapers last well and are available in different shapes.

Chemical stripping

For removing hardened old paint, the combination of chemical stripper and a scraper can be pretty quick. But remember - paint stripper is extremely toxic. Don't use it inside unless you can ensure very good ventilation.

Sugar soap

A useful alternative to sanding prior to repainting, especially if all you're doing is removing grease from an old gloss finish. Good for large surfaces, when the existing paint film is sound.

Hot-air gun

The heat softens the old paint film to allow much easier scraping. A burner or blowtorch will also do the job, but they're dangerous. Hot-air guns have no flame, so scorching is reduced - you're much less likely to burn the house down.

Paint removal machine

Paint-removal machine
A depth-controlled set of carbide blades rotates at high speed to scrape away the paint. These machines can be so finely set that individual layers of paint can be removed. Ideal for weatherboards and other flat surfaces. They cost close to $1000 to buy, but they're also available for hire.
