Filling Holes and Cracks - Part 2

In this video you will learn to fill holes and cracks with sawdust and wood filler.

Watch the video How to Fill Holes and Cracks Part 1.

Step 1 - Fill with sawdust.

To make a filling with sawdust, pour a small quantity of adhesive on scrap wood.

Add some sawdust and mix it well with a putty.

The sawdust should be fine.

It is advisable to use the sawdust from the same wood you are fixing.

Mix until the colour is consistent and the mixture is almost the colour of the wood.

Push in the mixture in the knothole, crack or hole and wipe off the excess immediately before it dries.

Leave the piece to dry for 3 to 4 hours.

You can now flatten it out with a paring chisel.

You may also use a shaving blade.

The adhesive has some plastic and it can be difficult to sand off.

Therefore it is better to avoid using excess adhesive.

Polish the area lightly with sandpaper.

Step 2 - Fill with a wood filler.

You can also use a wood filler to fill holes in a workpiece that you will eventually paint.

Choose a wood filler that matches the colour of the wood.

Mix the wood filler as per instructions.

In this case we will mix an equal quantity of resin and hardener.

Add some sawdust and mix well with the putty.

Apply the filler over the hole or the crack.

Wipe off any excess with the putty.

Let it dry for a few hours.

Add some sawdust over the filler so that it dries quickly.

Let it dry for a few hours.

Brush off the sawdust on the top.

Scrape the excess wood filler off with a plane blade iron.

Plane the workpiece to level it.

If there is a spot where the wood filler is protruding too much, you might need to chisel it off.

Finish by planing the workpiece.

You have successfully learnt to fill holes and cracks.
