My Buying Guides on Thompson Water Sealer

When I first decided to protect my deck from weather damage, I turned to Thompson Water Seal products. After some research and hands-on experience, I want to share what I learned to help you make the best choice for your project.

Understanding What Thompson Water Seal Is

Thompson Water Seal is a popular brand of waterproofing sealers designed to protect wood, concrete, and masonry surfaces from water damage. I found that these sealers penetrate the surface to repel water while allowing the material to breathe, which helps prevent cracking and peeling.

Types of Thompson Water Seal Products

There are a few different formulations, and choosing the right one depends on your needs:

  • Clear Water Sealers: I used this on my wooden fence to keep the natural look while protecting against moisture.
  • Semi-Transparent Stains: These add a bit of color and still let the wood grain show through. Perfect if you want a tint but not solid paint.
  • Solid Color Stains: Great for completely changing the color and hiding imperfections, although I didn’t go for this since I preferred a natural look.
  • Concrete Sealers: These are made specifically for driveways, patios, and walkways to prevent water penetration and damage.

What to Look for When Buying

Here are the factors I considered before purchasing:

  • Surface Type: Make sure the product is suitable for your surface—wood, concrete, or masonry.
  • Finish and Appearance: Decide if you want clear protection or a tinted finish.
  • Ease of Application: Some sealers are spray-friendly, while others require brushes or rollers. I found spray application quicker but less precise.
  • Drying Time: Depending on your schedule, drying time can be crucial. Thompson Water Seal products generally dry within a few hours.
  • Durability and Reapplication: Check how long the protection lasts. I learned that reapplication every 1-2 years keeps surfaces in top shape.
  • Weather Resistance: If you live in an area with harsh weather, pick a sealer with strong resistance to UV rays and mildew.

My Application Tips

From my experience, proper preparation is key:

  1. Clean the Surface Thoroughly: Dirt and mildew can prevent proper sealing.
  2. Apply on a Dry Day: Moisture in the air or on the surface can affect adhesion.
  3. Use Multiple Coats: I applied two coats for better protection.
  4. Follow Manufacturer Instructions: Each product has specific guidelines for best results.

Where to Buy Thompson Water Seal

I found Thompson Water Seal products easily at most home improvement stores like Home Depot and Lowe’s, as well as online retailers. Prices vary depending on the size and type, so shop around for deals.

Final Thoughts

Choosing the right Thompson Water Seal product and applying it correctly made a big difference in maintaining my outdoor wood surfaces. With the right sealer, you can extend the life of your wood, concrete, or masonry while keeping it looking great. I hope my guide helps you make an informed choice!
