What are Metal Decks?  

Metal decking is an outdoor decking that uses metal as a primary material. A metal deck is a strong and durable alternative to wood decking, which is prone to rot and decay. Metal decks are available in different materials, such as aluminum, copper, and stainless steel.   

How to Maintain Metal Decks 

Metal decking requires maintenance to keep it looking new and functional. Metal decks have unique needs that differ from wood decks.  

Practice Preventative Care 

Clean your deck regularly. Dirt and debris collect on metal decks, and as time passes, a significant amount of dirt and debris will inevitably end up on your deck. So, just as a standard of care, do yourself a favor and clean your deck regularly. That said, it’s much easier to clean your deck when it’s dry.  

If your deck is damp or rain is forecasted, it’s best to wait until the rain has stopped and the deck is dry before cleaning it. If your deck gets especially dirty, you can use a power washer or a garden hose to clean off the dirt. However, we recommend using a broom to remove light debris and a scraper to remove thick debris like dirt or gravel.  

Be careful not to use a metal scraper on your deck or railing, as it may scratch the surface. 

Restore Rusted Areas 

If your deck is very dirty and has some areas of rust, you may need to restore the damaged areas. You can remove the rusty areas by using a putty knife to scrape off the rust and then apply a coat of clear polyurethane. Don’t put too much pressure on the knife, though, or you may create a scratch on the deck surface.  

After removing the rust, let the polyurethane dry completely before applying another coat, or you may have to reapply when the job is done. Use a power washer or garden hose to clean the deck surface. Don’t use a garden hose with a sprinkler, as the water may get into the gaps and crevices, causing an unsightly mess.  

We also recommend wiping down the deck surface with a clean, dry cloth, or in the worst case, a brush or broom will work.  

Apply Paint with a Primer 

Have your metal deck painted if you want it to look fresh. One of the best ways to do this is with an acrylic primer, a type of paint that will adhere to the metal without needing additional coats. We recommend using a primer that is specifically designed for metal. It’s important to select a primer that has proper adhesion to metal, or the paint will not adhere properly.  

We recommend using a primer containing some corrosion inhibitor, as the primer will help prevent any corrosion after you paint the metal.
