The amount of time between sealer applications can be dependant on a few different factors. If your concrete is in a high-traffic area, such as walkways, patios, or pool decks, it may need resealing more often. Exposure to work areas, like garages, workshops, and sheds, can increase the frequency of resealing as well, due to the increased chance of chemicals being spilled or damage occurring. However, on average, concrete flooring should be resealed roughly every 2 to 5 years. If you notice that your concrete absorbs water quickly and it doesn’t bead up on the surface at all, it may be time to reseal.
