Hardscape maintenance is often an afterthought of homeowners and property managers. It's only when the surface begins to darken and the joints begin to fill with weeds and moss that thoughts about cleaning may arise. Unfortunately, this is when mistakes are often made. Pressure washing can be an effective way of removing dirt, grime, and organic material from the surface, however what many people fail to appreciate is that the loss of material from the joints of the pavers can lead to wash-out of the base layers and unwanted shifting of the hardscape. Paver cleaning should be thought of as a complete process of cleaning the surface, clearing and refilling the joints, and sealing the surface to lock everything in place and protect against unwanted shifting, the return of organics, etc.
The first step in revitalizing a hardscape is to strip any failed sealer if applicable, and begin to deep clean the surface. This involves the use of moderate to high pressure to rid the surface of any dirt, grime, and organic material, as well as to remove any heavy organics and old sand material from the paver joints.
After the surface has been cleaned and the joints have been exposed, an algicide blend will be flushed into the joints to help prevent against rapid regrowth on and between the pavers. This is especially important on jobs with heavy organic growth throughout the surface and between the pavers.
After the surface and joints have been cleaned and treated, the joints are then refilled with a sand blend specially designed for paver stabilization. Hydro compaction is used to draw the sand into the joints and minimize the likelihood of air pockets or inconsistencies in fill height.
After cleaning, treating, and refilling the joints, the pavers should be allowed to shed and evaporate any residual moisture. When the surface and joints are sufficiently dry, a sealer will be applied to the surface that. will both stabilize the paver joints and protect the surface from weathering.
