If plaster drips on the floor during your work, don’t fret. Plaster is water soluble and can be easily cleaned. However, the best way to prevent accidents is to do a good cover-up. Before you begin, cover the floors with heavy plastic. The plastic should be loosely taped together. If you are doing a repair, tape the plastic up the wall a bit for an even better floor covering. If plaster still managed to get on your floor, following a few easy techniques will return your floors to their original beauty.

Because plaster is water soluble, you can clean plaster out of carpet while it is wet or dry. If your carpet has a longer nap, it is best to clean it once it has dried. On other carpets, wipe up large amounts of plaster and then scrub the remainder out of the carpet. On long nap carpets, let the plaster dry and use your hands to crumble it out of the carpet. Once the excess is gone, use a small wet rag to remove the remaining plaster.

Hardwood Floors

Hardwood floors are easier to clean than carpeted floors. If you find the plaster while it is still wet, wipe up most of it. Whatever is left on the floor can be removed with a damp rag. If you find the plaster while it is dry, scrape it off with your work knife and use a wet rag to wipe up the remainder.
