Some homeowners have luck using pressure washers, but this only works for old or weaker concrete sealants and with very powerful pressure washers. You’ll get better results by pressure washing water-based sealants. However, it’s worth trying on any sealant if you’re hoping for the least toxic, least expensive, and most DIY-friendly option. To try this method, rent or buy the most powerful pressure washer you can find and take several passes at the concrete, completely pressure washing the entire area. You may need to repeat the process multiple times to see results.

There are times when you should remove all exterior paint before repainting. This includes when you need to get rid of lead-based paint (which should be done by a pro), or if you need to apply a different finish than what’s already there. Your house may also have too many pre-existing layers of old paint, in which case you’ll be better off getting rid of the old layers first.

If you recently splashed paint on the wrong area of a wooden object, remove it with a solvent or caustic paint stripper. Some paint that has yet to dry may be removable by hand with coarse sandpaper or a plastic scraper. Another trick for removing dried-on paint is rubbing a dab of nail polish remover on the paint to remove it, but avoid touching the bare wood surface.

A traditional German schmear uses mortar, making it unsuitable for adherence to painted surfaces. Professionals recommend removing any existing paint before applying mortar. However, you can rough up the painted surface and clean it to test if the mortar will stick. Remember that the underlying paint's texture and color may affect the schmear's final appearance—so starting with a bare brick wall will ensure the ideal finish.
