How to make an old pressure treated wood deck look new again

Hi Darlene, rent a pressure sprayer and take your time thoroughly cleaning the whole deck, it will look practically brand new when you're done!

Power washer, you can rent one for an afternoon. If there is green stuff on the boards, treat them with oxy clean, let it set for a few few min. Scrub. Then blast with water

there are a few things... a water sealing treatment for a natural look or you can sand and stain the deck. or paint it. once clean, its a blank canvass, and the wood looks a lot better - my aunts deck, the boards went back to the natural pine wood color.

Once you clean your deck well apply a linseed based product that soaks into the wood rather than laying on top of the wood like many deck products do. Check out this website for a product that I use and like: armstrongclarkstain.com

You might want a water proofing agent. There are an assortment to choose from. the power wash will take off paint chips etc, but you may need to sand it down as well Befor waterproofing it. You can opt to stain or paint

Wood decks need to be maintained on a regular basis. at least every four years.

Use pressure washer with Clorox let dry then Thompson's waterseal.

the power washing gets the grime off the boards, any chipped paint comes off as well.. if you have a paint or stain in place you will need an agent that strips them down to the bare wood. once you have a naked deck, there are water sealing agents to protect the wood. its similar to oiling it. it takes a good 2 coats on all the wood. it does not hide any wood grain. but it must be squeeky clean.

once you have it clean, you wait for it to dry...then you can use a deck sealer or stain and paint. the deck sealer is clear, you can see the wood grain.

Thank you
