Many homeowners prefer clear finishes for their wooden staircases, as they are intended to bring out the natural beauty of the timber as well as meet the demands that are likely to be placed on the finish. You might be surprised to learn that there are a variety of clear finishes to choose from – it’s important that you compare the characteristics to ensure you’ve made the right choice.

Wax
This finish creates a shine on the surface, although it’s really only a short term solution and will require frequent reapplication. It is considered safe when the solvents in the wax have evaporated. Wax is very easy to apply, can be easily removed with solvents and needs to be buffed.

Shellac
This finish creates some yellow or orange tint (depending on the grade you use) and offers fair protection against water. It’s quite a durable finish that is considered safe when the solvent evaporates. It is a difficult technique to master and can be removed if desired using alcohol.

Nitrocellulose Lacquer
This finish is transparent with a good gloss and it offers decent protection for wooden staircases. Although it is soft, it is somewhat durable. Extra protection is needed because it contains toxic solvents, it’s completely removable and it does require equipment to apply.

Conversion Varnish
This finish is also transparent with a good gloss and it offers excellent protection against many substances. It is hard and durable. Breathing protection is required for application, as toxic solvents are used, and it is difficult to reverse if you change your mind.

Linseed Oil
This finish offers a warm yellow glow that darkens with age. It offers very little protection but is fairly durable (depending on the number of coats applied). It’s relatively safe and easy to apply. To remove, it can be sanded out as the oil has been absorbed into the timber.

Tung Oil
This finish offers a warm glow that is lighter than that offered by linseed. It also offers very little protection but is fairly durable (depending on the number of coats). It’s relatively safe and easy to apply. To remove, it can be sanded out as the oil has been absorbed into the timber.

Alkyd Varnish
This finish offers wooden staircases a yellowish/orange tint and relatively good protection. It is quite durable and relatively safe. It is easy to apply, although you do need good technique to avoid streaking. It can be stripped from the surface using paint removers.

Polyurethane Varnish
This finish is transparent, although the application of many coats can make it look like plastic. It offers excellent protection against many substances, it’s very durable after a curing period, is relatively safe and can be stripped from the surface using paint removers.

We hope that the information provided above has enabled you to choose the most appropriate clear finish for your wooden staircase.
