Furniture Restoration Using Power Tools – Sanders And Abrasives

 

Furniture Restoration Project

Give new life to an old piece of furniture and see the transformation! In our furniture restoration example, we revitalised a tired looking, poorly painted pine bedside cabinet into something fresh and clean. Get your materials together, and give it a go!

Part 1 – Disassemble / strip down

Firstly, we removed the drawer knobs and drawer runners. We set these aside to use at the end of the project.

For this project, we wanted to have a wooden top contrasting with a painted base and drawers. With this in mind, we carefully removed the top. In our example, the top was held on with cam dowel bolts and a little glue. After undoing the cam dowels, we removed the panel pins at the top of the backboard. Here, we used a soft faced mallet and a gave it a light tap to loosen.


Part 2 – Sand up

With the cabinet fully apart, we could see what we had to work with. As the underside of the top had some dried glue still attached, we used a sharp chisel to remove it. At the same time, we also discovered a small crack in the top. This would be rectified after sanding the entire cabinet.

Here, our chosen sander was a Mirka DEROS 5650CV Random Orbit Sander. It is a great all rounder; lightweight and easy to handle with good dust clearance when attached to a vacuum extractor. Alternatively, the Makita BO5041 Random Orbit Sander is another great option.

If you use a coarse abrasive and a slightly reduced speed, a random orbital sander is very good stock removal machine. However, if you use a fine abrasive and increase the speed, it becomes an excellent finishing tool. For this project, we needed a bit of both which is why we chose two different grits of Abranet abrasive.

Why choose Abranet?

Abranet’s unique open mesh design provides a virtually dust free sanding experience, which leads to longer abrasive life. Other benefits include its high performance and versatility across a wide range of applications. Learn more about different Mirka abrasives.

With an 120g abrasive fitted, we lightly sanded over all surfaces of the cabinet body and the drawer fronts. We didn’t need to remove the paint but simply smooth over and clean, ready for the next paint covering.

As it was difficult to get into the corners with a round base sander, a good cork block helped with this.

In terms of the cabinet top, we wanted to remove all paint to take it down to the bare wood. For this, an 80g abrasive was ideal. In our experience, we find that anything finer than 80g clogs far too quickly and doesn’t perform as well. In all, using the random orbital sander, good extraction and 80g Abranet abrasive made light work of this sanding task with no clogging on the abrasive at all!

Part 3 – Repairs

As mentioned before, we discovered a crack in the top of the unit. As we didn’t want to leave the crack nor completely break open the top, we decided to glue the crack in situ.

Here, we lightly opened up the crack and forced in as much PVA glue as possible. To pull the glue through the crack to coat the inner surfaces, we used a vacuum! We then clamped it up and left for a couple of hours.

Part 4 – Finishing time

Finally, we gave the unit a thorough wipe over with a damp cloth to remove any residual dust that could affect the final chosen finish.

We then painted the cabinet body and used dye and oil on the top. As the cabinet body had some exposed knots, we treated with a knotting solution to prevent them showing through the final finish. As you can see, we chose to replace the old wooden knobs with new metal ones to finish the piece, however the choice is yours!
