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.
There are three types of clear topcoats used to seal natural wood or bleached furniture – polyurethane, polycrylic, and wax finishes. Each type of clear coat has different pros, cons, and projects that it's best suited for.
Pure Tung Oil is the top choice for an all-natural wood sealer. While we don't recommend you use it on large outdoor surfaces like decks or fencing, it's an excellent option for indoor furniture, butcher block, cutting boards, ax handles, and other wooden pieces. Use Tung Oil on unfinished wood.
Polyurethane is a commonly used wood finish that is known for high durability and water-resistance.
Thompson's Water Seal
This is why in most woodworking blogs, their water seal always tops the list of recommended wood sealers. Aside from resisting most types of mold and mildew, it's also long-lasting. So you won't have to worry about reapplying a sealer every couple of years.
Wax, oil and varnish are three materials that will protect your furniture and that you can easily apply at home yourself. The three options will maintain the most "natural" aspect of the furniture, preserving the grain of the wood without adding big touches of colour, as paints, lacquers, etc. would do.
Pine tar is one of the best protective products for any wood surface. It creates a breathable wood surface. One of its benefits is that it won't trap moisture. We recommend mixing authentic pine tar with purified linseed oil.
Products such as polyurethane, varnish and lacquer are most commonly used for the protection of outdoor wood furniture. Make sure to apply the finish over every surface — even underneath and in every crevice. If moisture works its way in, it will not be able to escape and your wood will become damaged.

Wood Oil: Offering more durability than a wax polish, Wood oils are easy to work with, very easy to repair (sand down scratches then reapply) but they do have slower drying times. Wood Varnish: Forming a seal on the surface of the wood, varnishes are the strongest of all wood finishes.
Which is better: polyurethane or polycrylic? Polyurethane is better for durability, but polycrylic is better for interior surfaces like cabinets, furniture, and trim. However, for light painted furniture and cabinets, polycyrlic is preferred because it doesn't yellow on the surface.
“Wood sealer” and “preservative” are different terms for the same type of product and are used interchangeably in the trade. The clear wood preservative produced by Olympic, for example, is recommended by its maker for protecting exterior wood from moisture damage, mildew, rot and decay.
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.
What's the Different Between a Sealer and a Waterproofer? Sealers and waterproofers perform similar functions, but they differ slightly in how they work. A wood or concrete sealer will protect the surface. Waterproofers are more durable than sealants because they penetrate the surface, filling in leaks or gaps.

Sealers Vs Primers
The best rule to adhere to is to apply at least two coats of sealer directly onto the raw wood. This will protect the wood and create a barrier. Then apply primer to enhance adhesion, return tooth to the surface, and whiten the surface for optimising paint colours you plan to apply over it.
Liquid sealants are one of the most common ways to waterproof wood. These sealants are applied directly to the surface of the wood and form an impermeable barrier against water penetration. It is important to apply several coats of sealant to ensure a thorough application.
A Sealer is a mixture of oils and resins as well. However, it produces low viscosity as compared to varnish, which simply means that the sealer practically penetrates in to the wood to nourish and protect not only the outside but more importantly, the inside.
