If applied correctly, Water Seal will last up to 4 years. This is dependent on conditions such as orientation of the wall and local climate.
It is not recommended where decks are subject to significant sun exposure. It also must be reapplied more often than most stains, typically every 2 to 3 years, depending on sun exposure. 1 Semi-transparent stain adds some color to the wood and offers a moderate amount of UV protection.
Only one coat of Thompson's® WaterSeal® Wood Sealer is necessary. A second coat can be added if more color is desired.
The advantage of this, they say, is the sealer provides additional protection against water and weather damage, while the stain helps reduce fading from UV rays. Sealers should last at least a year, with some lasting up to three years.
– THOMPSONS WATERSEAL STAIN & SEALER does not soak into the wood but dries on top like a paint.
Answer: The manufacturer of Thompson Water Seal recommended that you use their product with a plastic sprayer with a brass wand, such as our Chapin Premier sprayer. There are no concerns about it eroding any of the seals inside of it.
Stain offers little to no moisture protection, while sealant offers tremendous moisture protection.
Polyurethane is the most durable option for indoor woodworking projects. It's highly effective at protecting cabinets, doors, furniture, and floors from scratches and abrasive damage. Polyurethane is also water-resistance and is intended to enhance the natural appearance of the wood with a statin or mid-gloss finish.
Oil-based wood sealers are more durable and longer lasting. Unlike water-based solutions, oil-based wood sealers tend to penetrate deeper into the wood. This type of wood sealer emits toxic fumes and is flammable during the application process, so it's recommended that you apply it in a well-ventilated area.
You should reapply wood sealer at least every three years. In many cases, you need to seal a wood deck once a year. The more foot traffic and sun exposure your deck gets, the more often you need to apply deck sealant.
One coat is enough, but if more color is desired, a second coat can be applied within two hours before the first coat has dried. Be sure to read the back label to understand how to properly clean your tools after application. Let the deck dry for at least 24 hours and you're ready to replace the furniture.
Asphalt sealer and crack filler, if stored above freezing, will be good for a year (opened or unopened). PVC primer and Thompson's Water Seal™, sealed tightly, can be kept indefinitely (no minimum temperature), as can concrete bonding additive if stored above freezing.
However, most of the water-repellent sealers sold at home centers, paint stores and lumber yards are suitable for pressure-treated wood as well as other outdoor woods such as cedar and redwood. The directions for some, such as Thompson's Water Seal, specify pressure-treated wood as a suitable use.

Spar urethane, an outdoor-friendly polyurethane, contains UV absorbers that are ideal for maintaining an outdoor wood finish. It is available as both an oil-based and water-based product and also comes in a range of finishes from satin to gloss.
Marine spar varnish is the best type for outdoor use. Its key ingredients are linseed oil (pressed from flax seeds) and alkyd resin (made by reacting linseed oil with alcohol and acid). The film is flexible enough to move with wood as it shrinks and swells with shifts in humidity.
This fabric waterproofing spray contains UV inhibitors to resist color fading caused by the sun and penetrates below the surface to protect against moisture damage without leaving surfaces discolored, stiff or sticky.
DRYING TIME Thompson's Water Seal should be dry in 2 hours under normal conditions. Dry times depend on the texture & type of surface you're coating. Remove as much product as possible from equipment before cleaning.
