A high-quality polymeric sand installation should typically last three to five years. After this time, the sand will start to lose its effectiveness due to exposure to the elements, including rain, snow, ice, and UV rays. Weeds can get into the joints created by loose, fractured, or missing polymeric sand. Additionally, there's a chance that the pavers will shift as a result of the bedding sand deteriorating underneath. Changing the polymeric sand when necessary is the most crucial step in maintaining pavers and the greatest approach to safeguard your investment. It will stop unattractive weeds from growing up and destroying the appearance of your patio. 

PRESSURE WASHING

In many contexts, pressure washing and power washing are used interchangeably, and there is some disagreement over whether they are two distinct processes.

An industrial pressure washing surface cleaner is a device that rotates when water flows and has two to four high-pressure jets on a rotating bar. In certain systems, the user is shielded from spray and debris by a circular shroud that is wheeled and moved along the surface. This motion produces a uniformed cleaning pattern that may quickly clean flat surfaces. A single orifice that cannot be changed for spray pattern is commonly used in many low-cost household/consumer grade systems.
