Solid timber doors are ideal for exterior and interior installation in residential buildings. The material is sturdy and stable, so the door will provide security by limiting forceful access by intruders. Wood is also popular in homes because the natural appearance will advance the visual aesthetics of the home. In addition, you can refinish the surfaces by sanding, and you can apply protective coatings to restore and improve the wooden appeal.

If you are thinking about refinishing and restoring your timber doors, you should consider choosing varnish. This is a transparent and hard finishing coat or film, and it is designed to cover wooden surfaces without changing their colour. The varnish is waterproof and glossy, so it will protect your doors against damage from ultraviolet radiation and moisture. Here are the main forms of varnish to consider for your residential timber doors.

Polyurethane

Polyurethane is an advantageous varnish for timber doors because the product will create a durable coating. It is ideal for both interior and exterior doors since the layer will resist deterioration in adverse weather conditions. Basically, this material is made using microscopic polymer resin particles that bond to form an impenetrable coating. The varnish can be purchased in a range of sheens to suit your preference, and the layer is relatively easy to strip. On the other hand, you should note that the polyurethane can sometimes induce amber colouring over time.

Acrylic

An acrylic finish is an ideal alternative to the polyurethane varnish for your residential timber doors. Basically, this type of finishing product is water-based while standard polyurethane is solvent-borne. Therefore, acrylic is safer for the environment, and the application process will not lead to the release of unfavourable fumes. This varnish is also highly transparent and stable, and it will not sustain an amber colour after long-term exposure to sunlight. In addition, you will attain prolonged finish service after curing.

Shellac

Shellac is a popular varnish in residential environments, and it is fabricated using a resin secreted by a special insect. This material is dissolved in alcohol to create a consistent finishing product. It is easy to apply, so this is a suitable choice if you are thinking about finishing your door without professional assistance. You can purchase clear shellac or choose variations that range from blonde to a fairly rich orange hue. In addition, this coating will perform as a natural primer, stain, odour suppressant and high-gloss finish.

You should also inquire about alternative varnishes like alkyd, lacquer and drying oils from your supplier.
