Does your deck look tired as a result of
getting beaten by the weather? The following video will show you how to
restore your deck’s beauty and bring it back to life This project will feature the use of
many of the most popular power sanding tools currently on the market today, many of which may already be in your workshop You will need a nail set, hammer, extension cord, belt sander, 36, 60, and 80 grit ceramic sanding
belts, a belt cleaning stick, random orbit orbital sander, 80 and 120 grit film back sanding disks, multi tool or detail sander, 80 and 100
grit detail multi tool refills, 120 grit sanding sponges, a wet/dry vacuum, hand brush, and a long flat head
screwdriver Use a nail set and hammer to recess all nail heads, so that they are below the surface of the deck. This will make sure the nails are secure to the frame and will prevent damage to your sanding belts and discs Sanding is the key to restoring your
deck to its original beauty This will be the most time consuming
part of the project and it’s the most critical to ensure the best results The majority of the project you’ll be using a belt sander Start belt sanding in the corner and work
your way out This will keep you from getting boxed in Be sure to firmly grip your belt sander to maintain control Sanding is a process of steps So begin sanding with an extra coarse 36
grit ceramic sanding belt for fast removal of any old stains and
sealers You will immediately start to see the
wood come back to life Be sure to sand in line with the planks This will minimize deep scratches left behind when sanding against the grain During sanding, your belts may become clogged with debris and particles from stains and sealers You can extend the life of your belts by using an abrasive belt cleaning stick to pull dust and
debris from the abrasive surface Now that your belt is clean, you’re ready to continue sanding Once you have sanded the entire deck switch to a coarse 60 grit ceramic sanding belt This will remove the scratches left behind from the previous grit Again, sand the entire deck surface Use your hand brush, or wet dry vac, to remove dust between each grit. This will ensure that your abrasive is in contact with the surface and reduce clogging Repeat before moving on to the next grit, as dust and debris accumulate Finally, use a medium 80 grit ceramic sanding belt to achieve the final finish for your deck This will remove all the 60 grit scratches and provide a smoother surface This final step is very important to
produce a smooth finish on your deck surface Once the surface of your deck is sanded, it’s time to turn your attention to the
handrails For best results, use a random orbit or palm grip sander on these flat surfaces Assess the condition of your hand
rails to determine grit selection Start with an extra coarse 40 grit if your rails require fast, extreme removal of old stains and sealers Once you’re done sanding all of the rails with 40 grit use an 80 or 100 grit to remove the 40
grit scratches To knock down the sharp edges of
your hand rails, use a 120 grit sanding sponge This will quickly round the sharp edges, to prevent injury Most decks have some type of decorative
details installed, such as spindles These present a challenge to properly sand and prepare for sealing Use either a detail or multi tool sander to sand in the tight corners and small areas These tools are also ideal for sanding the vertical spindles that support handrails As with other parts of your deck, assess the condition of these decorative elements to determine grit selection Start with an extra coarse 40 grit, if you require fast, extreme removal of old stains and sealers Now that the hard part is over, it’s time to clean up the deck in preparation for staining or sealing Once all of the elements above your deck
surface are cleaned, then focus on cleaning the main part of
the deck Use your long screwdriver to dig out
debris that builds up in the gaps between the planks Use your wet dry vac to remove all dust and
debris from the entire surface of the deck Be thorough in your cleaning Any dust and dirt left behind can affect the quality of your finish Now it’s time to apply your finish Determine what kind of stain or sealer you want to apply to your deck Your application technique will vary
based upon the size and area of the deck you are working with Consult your local paint store to determine the best finish and tools to use to apply your stain or sealer All your planning and hard work is starting to pay off in no time you’ll have a beautifully restored deck that you can enjoy for years to come
