Should you power wash or sand a deck first? This is a common question among homeowners and deck enthusiasts. Whether you’re looking to restore the beauty of your deck or prepare it for refinishing, understanding the sequence of these tasks is crucial. Both power washing and sanding play vital roles in deck maintenance, but their order can significantly impact the final outcome.
Power washing is often the first step in deck restoration. It helps remove dirt, mildew, and other debris that can accumulate over time. However, if your deck has extensive damage or old paint, sanding might need to be performed before power washing. In this article, we’ll discuss the importance of each step and provide a guide on the best order to tackle them.
Power washing first can be beneficial because it allows you to quickly and efficiently remove loose dirt and grime. This step is especially important if your deck has been exposed to harsh weather conditions or has not been cleaned in a while. By starting with power washing, you ensure that the subsequent sanding process focuses on the deck’s actual surface rather than just the dirt and grime.
However, if your deck has old paint, peeling wood, or significant wear and tear, sanding should be performed before power washing. Sanding helps remove the old paint, smooth out rough surfaces, and prepare the deck for a fresh coat of sealant or stain. By sanding first, you avoid the risk of damaging the deck further by applying pressure during power washing.
When it comes to the actual sanding process, it’s essential to use the right equipment and technique. A power sander can be effective, but a manual sandpaper block or an orbital sander can provide more control and help prevent gouges in the wood. Sanding should be done in the direction of the wood grain to ensure a smooth finish.
Once the deck has been sanded, it’s time to power wash. Be sure to use a low-pressure nozzle to avoid damaging the wood. After power washing, allow the deck to dry completely before applying any sealant or stain. This ensures that the protective coating will adhere properly and last longer.
In conclusion, the order in which you power wash and sand your deck depends on the condition of the wood and any existing coatings. If your deck has old paint or significant damage, start with sanding to prepare the surface. If the deck is relatively clean and in good condition, power washing can be the first step. By following these guidelines, you can ensure a successful deck restoration and extend the life of your outdoor space.
