My Buying Guides on Thompson Water Sealer
When I first decided to protect my deck and outdoor wood surfaces, I turned to Thompson Water Seal products. After trying a few options and learning what works best, I want to share my experience and help you choose the right sealer for your needs. Here’s what I learned along the way.
Understanding Thompson Water Seal Products
Thompson Water Seal offers a range of waterproofing sealers designed to protect wood, concrete, brick, and other outdoor surfaces from water damage, mildew, and UV rays. They come in different formulas like clear sealers, semi-transparent stains, and solid color stains. Knowing which type fits your project is key.
Types of Thompson Water Sealers I’ve Used
- Clear Water Sealers: I used these when I wanted to keep the natural look of my wood while adding water resistance. They offer protection without changing the color but need more frequent reapplication.
- Semi-Transparent Stains: These were perfect when I wanted to highlight the wood grain but add a touch of color and better UV protection.
- Solid Color Stains: For areas where I wanted to completely change or refresh the color of the wood, these provided the most durable and opaque coverage.
Choosing the Right Sealer for Your Project
Think about the surface and your goals. For my deck, I preferred a semi-transparent stain because it balanced protection and appearance. For my concrete patio, I went with a clear waterproofing sealer. Also, consider the climate—if you live in a rainy or snowy area, choose a product with strong water repellency and mildew resistance.
Application Tips from My Experience
- Always start with a clean, dry surface. I cleaned my deck thoroughly and let it dry for at least 24 hours before applying.
- Use a brush, roller, or sprayer for even coverage. I found a brush gave me the best control around railings and corners.
- Apply multiple thin coats rather than one heavy coat to avoid peeling or uneven drying.
- Follow the manufacturer’s drying times between coats for the best results.
How Often to Reapply
From my experience, clear sealers usually need reapplication every 1-2 years, while semi-transparent and solid stains can last 3-5 years depending on sun exposure and wear. I keep an eye on the surface and touch up when I notice water no longer beads on the wood.
Final Thoughts
Thompson Water Seal has been a reliable choice for me, offering a good balance of protection and aesthetic options. By choosing the right type and applying it properly, you can extend the life of your outdoor surfaces and keep them looking great for years. I hope my guide helps you make an informed decision!
