How To Powerwash & Stain A Fence. Tips staining or painting a fence.
What happens here
Before applying high-pressure water to the fence, it's crucial to prime the power washer's pump to remove any air from the water line. With the power washer running, remove the nozzle tip from the gun. Squeeze the trigger to allow water to flow freely through the gun for approximately 30 seconds. This process purges air from the pump and hose, preventing pressure fluctuations and ensuring a steady, strong spray. Once the air is purged and a steady stream of water is observed, reattach the nozzle tip.
Goal: Remove air from the power washer's pump and hose for consistent pressure.
