Steps To Follow

Below, you will find out the proper steps that you need to follow to sand a deck with a drum sander

Step 1: Check Everything in the Deck

First of all, take the push broom and sweep the deck. Make sure all the visible and hidden debris are getting cleaned. Check the fastener's joints, and if it is not in its original position, fix it again by drilling the screws onto it. Use the nails, hammer, and screwdriver bits along with that. 

If you find out that the boards are not in its regular shape, take help from the decking screws. Use it to connect the board with the joists. 

Step 2: Clean the Whole Area

Pick the bucket and pour water and detergent in it. Mix it to form a solution and damp a sponge or mop onto it. Gently clean the whole deck with the sponge or mop. Throw some clean water in the area and leave it for a day to dry. 

In this time, check for any invisible debris on the surface and between the boards. If you find some of it mainly between the boards, pull all of it out with the paint scraper. 

Step 3: Start Sanding

Take the drum sander and starting sanding the deck. Don’t be in a hurry and be patient throughout the whole process. Start with the 20-grit sandpaper. If necessary, switch it with 50-grit depending on the condition of your wooden deck. 

Always remember that the lower sequenced sandpaper is used to sand on very rough surfaces and the higher one you can use for the finishing touch (mainly to sand around the edges). 

For sanding the corners and below the bench, use the palm sander. After the sanding part is done, clean the newly formed dust with the vacuum cleaner. You can also use the leaf blower as an alternative if you don’t have the cleaner in the first place. 

Step 4: Fix the Cracks or Wholes

As you have completed the sanding and cleaning, you now can shift your effort towards filling the scratches, holes, and cracks. Use Epoxy wood filler in this case as this one is very efficient in repairing any uneven areas within a small amount of time. 

Take the putty knife and start applying the filler onto the problematic areas. Always press the knife with pressure so that the bonds between the filler and the areas are getting tight. Leave it for some amount of time after that. 

Step 5: Finish It 

Start sanding again, and this time, you should increase the grit sequence of the sandpaper. If you have sanded with 20-grit, change it with 36- or 50-grit. Choose the best one according to your preference. This process is critical as the change in sandpaper grit will sand all of the untouched scratched areas that you might have left accidentally.

Vacuum the area again, and for the finishing touch, use the 80- or 100-grit sandpaper. After smoothening the rough surfaces, do the cleaning.
