In the south, a deck is one of the most used and enjoyed spaces during the summer months. Building decks can be quite expensive. Therefore, protecting this investment should be one of the most important procedures a homeowner should consider. Pressure washing your deck is one of the best ways to keep the surface free from mold, mildew, and other debris.
Why Pressure Wash Your Deck?
Over time, pollen, leaves, and dirt can accumulate on the deck, posing a risk to the longevity of the deck. A proper power washing will remove this grime and restore the deck to its natural beauty. However, it is extremely important that the deck is washed correctly due to the potential damage that could be done if it is washed by an inexperienced hand.
How To Pressure Wash a Deck
When pressure washing a deck, it is important to look out for certain pitfalls.
Using the right pressure: The most common mistake newbie washers make is turning the pressure up too high. It is critical that the washer maintain low water pressure when washing a deck due to the damage that could be done if the pressure is too high.
Picking the right nozzle: Another important factor is to select a nozzle that will not cause excessive damage to the wood. My favorite nozzle to use when washing a deck is 40 40-degree tip.
Keeping distance: The last factor to consider is maintaining proper distance between the nozzle of the washer and the deck. If the tip is too close, the wood could be damaged due to high pressure.
When To Avoid A Wash
Old or weak wood: When the deck is old or may be damaged by termites, it is essential to avoid washing the deck. It is probably a good idea to just replace the deck.
Artificial decks: Artificial decks can be damaged by a high-pressure wash, so it is
essential to contact the manufacturer to consider the steps that should be taken.
