Sealing a patio is an important part of maintaining the area and ensuring it looks great for years to come. But how long does the sealant last? The answer depends on a variety of factors, including the quality of the sealant, environmental conditions, and how much foot traffic the area receives. Generally speaking, you can expect a high-quality sealant to last three to five years. This is when you'll start to notice that water no longer forms droplets on the surface, but instead seeps into it.
Of course, this timeline can be shortened or lengthened depending on the climate and how often the area is used. For example, if you have a mild climate and don't use your patio often, you may be able to go longer between sealings. On the other hand, if you have harsh winters and frequently host outdoor parties, you may need to re-seal more often. It's also important to note that paving stone sealants have a limited shelf life.
Most sealants are good for 12 to 18 months after purchase, so it's best to use them within the first few months of buying them. Otherwise, they may not work as effectively. In addition to protecting your patio from water damage and dirt, sealing can also help prevent plant growth and insect infestations. To get the most out of your sealant, it's important to choose the right one for your pavers and reapply it every three to five years.
Regular maintenance and cleaning can also help extend its lifespan. If you're not interested in doing it yourself, there are plenty of companies that specialize in installing and sealing pavers.
