6 Steps for Restoring a Deck for Cheap

A well-loved and well-used deck may need to be restored now and again. Restoring and repairing your Decking is crucial for keeping up the appearance of your Deck, as well as the safety of it. A weathered deck can become slippery from mildew, unstable from rot and could also splinter and warp. Keep yourself and other users safe and your Deck looking attractive with regular maintenance and upkeep.

Before starting on your restoration - be sure to check for any rotten or damaged joists. If you come across any rotten or damaged boards, joists and posts, see our blog here


When restoring a deck, you want to make sure that you are starting from a blank canvas. Wooden decks should be treated, stained and maintained annually. Start by removing any furniture, garden plants and other items from your Deck.

Inspect all of your Decking Boards and Joists, if any have rot, splinters, or nails protruding out of the Deck. Replace or repair the Boards.

If your Boards or Joists are partly rotted, remove the dead and rotted wood with a knife or scraper. If the Board or Joist is beyond repair, remove the Board by carefully prying the nails and screws loose and removing the Board.

Cut a replacement Board and fix it to your Joists with new screws, installing by drilling the screws through the surface of the wood into the supporting structure below. Make sure to leave a couple of inches clearance on either edge of the Deck.

Then begin to remove any old varnish or paint from the surface of the wooden boards.

You can do this with a paint scraper by applying pressure on one side of the Board, moving the scraper forward along the Deck, making sure to follow the direction of the grain.

Once you have removed the old deck stain, paint or varnish, with your sander (manual or power), work your way around your entire Deck, sanding each area to remove any wood stain or leftover treatment.

Keep sanding your Deck until the surface is clear of any material and you are left with bare wood. Make sure to sand all marks and areas of your Deck, so your surface is all the same level.

Top Tip: When sanding, make sure to use 60-80 grit sandpaper on your Deck Boards and 80 -100 on any handrails or spindles.


Removing the old Deck surface can also be achieved by using a Deck stripper. Deck stripper has the advantage of removing old paint and varnishing and helping to wash any stains from your Deck. A Deck Stripper works by breaking down the old stain leaving your Decking primed and ready to be brightened, resealed or painted. After initially sanding the Deck, a stripper can be used to remove any stain or old sealer that the sander may have missed.

While you should have gotten all old varnish, paint and stain off of your Decking Boards during the sanding process, leftover dirt, debris and fibres may still be on the Boards surface.

Start by sweeping the entity of your Deck, removing any loose dirt with a stiff bristle brush. Then make sure you set your Pressure washer on a low setting and rinse any dirt away.

Once your Deck is clear of any debris, apply your Decking Cleaner, following the brand's instructions or your soap solutions. Let your Decking Cleaner or treatment soak into your Boards for 5-10 minutes.

With a stiff bristle brush, work the solution into the Boards, paying particular attention to the wood grain and removing dirt from the indents and grains within the wood. Cleaning and Brushing your Deck's surface also helps remove any leftover stripper or sander grit from the Boards surfaces.

With a smaller brush, make sure to scrub the areas between your Boards, the edges and handrails.

Deck finish can apply to either a sealer or a stain. Both are engineered to help protect your wood from the elements. Sealers are often transparent and allow the full colour of your wood and the wood grain to show through. However, Deck stain is often semi-transparent or available in solid colours. A semi-transparent stain can allow your natural wood grain to show through, but the stain can subtly change and brighten the tone of your wood deck.

Before applying your wood stain across your Decking, test your Deck to see if it is ready. Pour a bit of water onto your Deck. If it gets absorbed into the wood within 10 seconds, then your Deck is ready for stain.

Adding a sealer or stain to your Decking changes how your Decking looks, protects the Boards, and prevents moisture from entering the wood's pore, causing mildew growth and rot.

Sanding your wood deck before applying your sealer or stain means the stain should be able to penetrate the wood, increasing the longevity of the stain and helping your Decking Boards withstand the elements.

Make sure your Deck is completely dry. Then add a Deck stain to your Deck using a paintbrush, or paint roller. Paint your chosen stain across the Deck using a paint roller or brush, and make sure to follow the same direction as your woodgrain.

Start from one end of your Deck and brush your sealer into your wood. Make sure to use a smaller brush to get in between your Decking Boards, any railings and the edges.

Wait for the stain or sealant to dry before applying a second coat.

TIP: Test multiple stains on your Deck, making sure to choose the correct stain for you. Deck Stain are often available in a range of colours and tones, so make sure you choose the correct colour for your home improvement project.


Back Brushing is a term used to describe the action of working your chosen finish into your Deck wood. Make sure the finish is absorbed evenly across the entirety of your Deck. This is sometimes known as refinishing.

Refinishing your Deck with Back Brushing can be done either with an airless sprayer or manually. Ensure you have a high-quality, wide Brush. Using a narrow brush will result in visible brush marks across the surfaces of your Deck.

With your brush, apply pressure and distribute your finish into your Deck, making sure that the finish is applied into the wood grain, end gaps, and seams across your Deck. Back brush the finish to remove any drips.
