Steps To Follow

Below, you will find out all the steps that you can follow to use a random orbital sander.

Step 1: Secure the Wooden Material

Before you start sanding, you should secure the rough wooden material that you are going to sand. We highly recommend that you should use a clamp in this case. This will make sure that the element doesn’t get tilted in the middle of your work. Check whether the wood is getting tightly fixed with the clamp or not.

After that, connect the sander with the ventilation system. There will be a huge amount of accumulated dust throughout the whole project, and the ventilation system will save your time and effort by collecting all of the wooden dust.

Step 2: Use the Sandpaper

Sandpaper with lower grit sequence is used to sand on sturdy rough surfaces, and the higher grit sequence you can use for the finishing touch. So, check the wooden surface to get an idea about its roughness.

For the strong rough surfaces, use the sandpaper between 40-grit to 60-grit. To get smooth edges and for the finishing touch, sandpaper between 180-grit to 220-grit will be the best that you should go for.

Step 3: Turn on the Random Orbital Sander

Wear the safety goggles and the dust mask before you turn on the machine. Start with 40-grit sandpaper first on the rough surfaces. Connect it with the sander and turn on the machine. Wait for some seconds before the engine reaches its full speed. When the speed is at its maximum, gently put it onto the wood surface.

Start sanding in the line of the wood grain. If you are not happy with this sandpaper, increase it to 60-grit. Apply minimum pressure on the wood with sandpaper, or else you will accidentally leave some unwanted marks on the wooden surface.

When the rough surfaces got smoother according to your desire, replace the 40 or 60-grit with 180-grit sandpaper. Sand all the edges gently and take your time to get the desired result. You can repeat the process with 220-grit sandpaper for the perfect coating.

Step 4: Do the Cleaning

When you finish sanding all the areas, turn off the machine. Take the tack rag and wipe the leftover dust. If you find more, use the vacuum cleaner. Thus, you have completed the task successfully. Congrats!
