- When handling varnish, always wear rubber gloves (or similar material). It is tough to remove dry varnish from leather because it cannot be washed off with soap and water.
- Before use, put the varnish into the jar and stir. Also, don’t forget to stir the varnish regularly, as it may settle slightly. You can start the varnish with a brush.
- Using a soap brush, apply the varnish to the wood in long, smooth lines. Paint along the wood grain promotes uniform penetration of the varnish.
- Hold the brush vertically so that only the nib touches wood. Otherwise, the varnish will be unevenly applied. If you use a thin layer, you will get a better finish, so don’t overuse it.
