Due to harsh weather conditions such as rain and harmful UV rays, it becomes necessary to protect exterior surfaces. The same goes for landscape pavers. Simply put, pavers will last longer and retain more of their original beauty if they are sealed and maintained on a regular basis.
Knowing how to seal pavers correctly can save you a lot of time and effort. It can also mean the difference between a simple weekend DIY project or having to hire it out to a professional. To seal pavers of any sort you first have to clean the surface. This most likely means using a pressure washer. If no stains are present on the pavers then using chemicals is not necessary. A pressure washer will remove any dirt, grime and pesky weeds or moss that have grown up through the sand joints. If stains are present like irrigation rust or oil then use a cleaner specific to that stain.
Allow the pavers to dry for several days after cleaning. Most likely you will have to add new joint sand between the pavers. It is recommended to use polymeric sand. It can be poured onto the surface and brushed into the joints using a push broom. Once the joints are full, use a leaf blower held mostly parallel to the surface to remove any extra sand residue without blowing it out of the joints.
Choose a paver sealer that fits your needs. Paver sealers range from a non-appearance altering matte finish to a more glossy or “wet look” finish. Choose whatever sealer fits your preference. Most sealers will apply in the same fashion. Start in a corner of the surface that makes sense so you can work your way across the surface without becoming trapped by wet sealer. To seal pavers use a roller or garden type sprayer. Apply enough sealer so the surface looks wet. Cover the entire surface including the sand joints. Work in small areas at a time applying sealer evenly.
In some cases, two coats may be necessary depending on the product. If you are using a non slip additive in your sealer then two coats are a must. The paver sealer will enhance the natural beauty of the surface. It also solidifies the joint sand to create a weatherproof seal and helps keep weeds down. Sealing pavers is the best way to ensure a long lasting beautiful paver surface.
