If your concrete stains are green in color, it indicates the presence of mold or algae—which you should address right away. If left unattended, mold will spread to other areas throughout the home. However, be careful not to disturb mold on indoor concrete surfaces and work with a local mold remediation specialist for specialized care. Once free from mold and algae, seal your concrete to eliminate pores and gaps.

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.

If your garage floor is heavily soiled or stained, then it’s a good idea to powerwash it with a concrete cleaner before sealing. This process will remove dirt and debris to help the new sealer bond to the concrete properly, and it will also improve the look of your sealed garage floor. After power washing your floor, make sure you let the concrete dry completely before applying sealant, usually for 24 to 48 hours.

Periodic sealing and cleaning to maintain appearance and integrity.
