The best way to treat untreated wood for outdoor use is by applying a wood sealer, varnish, or finishing oil to the surface of the wood.
To make wood waterproof naturally, use either polymerized linseed oil or tung oil, which are the two best natural wood waterproofing products. Refined hemp oil and walnut oil can also be used, but you will have to apply a repeat coat more quickly.
Paint Or Seal Unfinished Furniture
Bare wood, when left unfinished, keeps your furniture with a natural wood look but the risk is exposing it to harsh elements, even if it's indoors, such as light, dust, moisture and water damage, making it more susceptible to stains, warping and cracking.
To seal wood properly first prepare the surface by sanding it smooth and, if you like, staining it a color. Then you can apply a sealant, but there are many to choose from. The three most common sealants are polyurethane, shellac, and lacquer, and each requires a different method of application.
Products containing danish, linseed, teak and tung oil are popular choices for a beautiful, waterproofed finish. Many of the internal wood finishes you'll find commercially available will have a mixture of oil, polyurethane and mineral spirits to improve the application process and drying times.
1. Apply a coat of polyurethane, varnish, or lacquer to protect the wood from penetrating humidity and moisture that can seep into your deck and other outdoor wood furnishings. 2. Finish and waterproof wood with a professional-grade wood stain and sealer combo and repaint when necessary.
With this in mind, believe it or not, a bit of canola oil and vinegar makes a brilliant wood sealant, protecting wood from burrowing insects, wear and water. As well as this, this can be reapplied to revitalize the wood, something that won't work without sanding off varnish.
The Traditional Way: Linseed Oil
Today, it can still help protect wood from water! All you have to do is apply it with a soft brush to the wood that has been cleaned well. Let the oil soak for a while before reapplying it in the same manner. You can oil as often as once a week or up to twice a year.
Untreated wood is the most susceptible to rot, fungi, and general weathering. It's extremely important that you use a wood preservative first. You can either use a wax enriched preservative for an all-round coating or alternatively use a wax-free preserver if you want to then use a stain or a paint on top.
Outdoor wood stains are water repellant, so they make the wood waterproof, that is protecting it against water and, as a result, against mold. The only problem is that it is a short-term protection. As the stain wears out, the water easily finds a tiny crack to penetrate the wood.
When well-maintained, paint seals wood and protects it from water, effectively waterproofing it. However, when cracks appear in the paint, water can reach the wood, and the wood is no longer waterproof.
Available in both clear and coloured options, wood preservers work similarly to stains, dyes and oils, providing waterproofing and as well as protection against rot and decay. Resistant to mould, algae growth and woodworm attacks, wood preserver also has UV protectors that resist fading and the natural greying process.
Sealing your outdoor wood once or twice a year - depending on your climate conditions - is important to maintaining the quality, and re-staining helps maintain its style. You could even try different colors of stain for a different look each year.
Thompson's WaterSeal has clearly not been a consumer favorite with deck stains or sealers. Mainly as it does not offer any UV protection and it grays in a few months. The Transparent and Semi-Transparent versions are prone to premature peeling and wearing after about 1 year.
Fully clean the wood with biocidal cleaner and apply an undercoat wood preservative to protect against woodworm and rot. If you'd like to give your outdoor wood a new look, stain the wood to a vivid colour or subtle tint. Finishes seal the wood from moisture, rain and (with some finishes) UV radiation.
Cypress, redwood, and cedar are three softwoods that have natural moisture-wicking properties and make fine choices for outdoor furniture.
As well as waterproofing the wood, varnish can also prevent wooden surfaces from getting scratched. Finishing wood with a product such as varnish, serves to protect wood from the little knocks and spills that are inevitable in a busy family home.
Shellac. In my opinion, shellac is the best natural wood finish for one main reason: it's the most protective natural finish on the market. Unlike other options, shellac forms a barrier on top of the wood, stopping water, dirt, and other things (*cough*crayon*cough) from reaching the pores of the wood.
Wood is dried-out and dull if you do not apply some sort of sealer. Staining and finishing are two very different things. By applying pigments, a stain is meant to darken or dye wood, but the wood is not preserved by staining.

Yes! A polyurethane wood finish looks beautiful and is one of the most durable top coats for wood finishes. It works great on stained wood, raw wood, weathered wood finishes, and painted wood finishes too.
