My Buying Guides on Thompson’s Waterseal Waterproofing Wood Sealer

Understanding What Thompson’s Waterseal Is
Thompson’s Waterseal is a waterproofing wood sealer designed to protect wood from water damage, mildew, and UV rays. From decks to fences, it helps extend the life of wood surfaces by preventing moisture penetration. When I applied it, I noticed how it enhanced the wood’s natural look while adding a protective layer.
Types of Thompson’s Waterseal Products
There are several variations of this sealer, including clear, tinted, and semi-transparent options. I chose the clear version for my deck because I wanted to maintain the original wood color. If you want to add some color while still protecting your wood, the tinted options might be better suited for you.
Choosing the Right Finish
The sealer comes in different finishes: matte, satin, and gloss. I went with the satin finish since it gave a subtle sheen without being too shiny. Your choice will depend on your aesthetic preference and the look you want for your wood.
Application Process and Tips
Applying Thompson’s Waterseal is straightforward, but I found some tips helped me get the best results:
- Make sure the wood is clean and dry before application.
- Use a brush, roller, or sprayer for even coverage.
- Apply in thin coats and allow each coat to dry thoroughly.
- Plan to apply 2-3 coats for optimal protection.
- Avoid applying in direct sunlight or extreme temperatures to prevent uneven drying.
Durability and Maintenance
From my experience, the sealer lasts about 1-2 years before needing a reapplication, depending on weather exposure. Regular maintenance, such as cleaning the wood surface and reapplying the sealer as needed, keeps the wood looking fresh and protected.
Pros and Cons Based on My Use
Pros:
- Easy to apply with good coverage
- Enhances natural wood appearance
- Provides solid waterproof protection
- Available in various finishes and tints
Cons:
- Needs reapplication every 1-2 years
- Slight odor during application (make sure to ventilate)
- Not suitable for heavily weathered or damaged wood without prior repair
Where to Buy and Price Considerations
I purchased mine at a local hardware store and also found good deals online. Prices vary depending on the size of the container and the product variant, but it’s generally affordable for the protection it offers. Buying in larger quantities can save money if you have a big project.
