The Thompson's WaterSeal is known for superior waterproofing abilities, maintaining the color of your deck, and giving your deck or fence a fresh, clean look. However, it can be disappointing if you need sun protection, and truthfully, the application process can also take a toll on you.
Read on to learn the main features you expect to get from this Thompson's Waterseal, such as ease of application, performance as a waterproofer, UV graying protection, stain and mildew prevention, and durability.
1. Ease of application
This sealer is easy to apply, but this depends on the quality and state of your wooden surface. However, these are some general directions to follow before applying.
- Only use on wooden surfaces
- Apply during warmer seasons; 50°F during application followed by 48 hours with the same temperature and no rain
- Apply on porous wood; you can perform a splash test to see if water beads form on the surface. If they do, your surface does not require treating
- Do not apply on stained surfaces
- Do not use as a paint additive; you will need to sand previous paint before applying
- Store in a cool, dry place; avoid freezing
- Apply a thin layer
With these manufacturer recommendations out of the way, you will need to get down to applying your water seal. If your deck needs preparation before treating, you will need to scrape, brush, pressure-wash, and dry all impurities such as leaves, mildew, algae, paint, stains, oil, dirt, and more. In short, your surface needs to be smooth and clean before you can apply.
The application process is easy as you will only need to shake the bottle well before applying a light layer all over the surface. You will also need to shake or mix the contents occasionally as you apply. Additionally, you can use a brush, roller, paint pad, or sprayer for application.
After you apply, give the surface at least 48 hours to dry, but this also depends on the temperature and lack of rain. When it dries, you can apply your paint after 30 days.
2. Appearance after application
This Thompson's Waterseal does not alter the appearance of your surface, so your deck will look clean and new after the initial application.
One of the best qualities of the Thompson's Waterseal is the ability to repel water. After application, a splash test leaves water beads on the surface that do not get absorbed. Hence, your deck will be safe from water damage for the rainy season and winter.
According to the manufacturer, how long the Thompson's Waterseal lasts depends on the environment.
You can perform a splash test every year to see how well the waterproofing is holding up. Generally, the treatment lasts up to two or three years, after which environmental elements such as snow, rain, and sun damage will have started to affect performance.
Additionally, the state of your deck before applying this coating affects how well the Thompson's Waterseal will perform. For example, a deck that had mildew or algae is likely to darken the coat.
5. UV Protection
While the company states that this Thompsons Waterseal offers UV protection, the performance is quite dismal, and you might notice some UV graying a few months after application. This poor performance is arguably the biggest reason you could find not to use the Thompson's Waterseal.
6. Mildew, algae, mold prevention
You want a coating that can keep fungi away from your deck and other surfaces for a long time. The Thompson's Waterseal resists mildew, algae, and mold for a few years, after which you will need to reapply it.
As the waterproofing wears off, you will notice that it becomes easier for the wood to get moist, thus enabling the growth of these fungi.
The Thompson's Waterseal comes at a very affordable price and in different size bottles. You can buy this model with a 1.2-gallon capacity, while you can also find it in several packs suitable for different deck sizes.
As seen above, the Thompson's WaterSeal comes in different capacities for your deck size. Thus, it is best to discuss the best surfaces to treat to get the ideal coverage. According to the manufacturer, you can use the Waterseal on;
- Exterior wooden structures
- Wooden furniture
The type of wood you want to treat will not affect performance, and you can expect to get good coverage of 200-400 sq. ft per gallon. In addition, you will only need to apply one thin layer of the coating so it can dry faster.
While it is not the best for offering UV protection, the Thompson's Waterseal Wood Protector is your best bet for keeping your outdoor wooden furniture in good condition for many years. As a clear sealer, it will not stain your fixtures; it will only improve the appearance, highlighting the natural tone better.
The sealer is also affordable and easy to apply when your deck is well maintained. It will help you keep mildew, algae, mold, water, and dirt away. Additionally, it makes it easier to clean the deck area or wipe your outdoor furniture when you feel the need to.
