The Best Way to Apply Thompson’s Water Seal to Your Deck

Applying a high-quality deck sealant is essential for maintaining the longevity and aesthetic appeal of your outdoor living space. Among the various options available, Thompson’s Water Seal has been a popular choice for many homeowners. However, to ensure a job well done, it is crucial to follow the manufacturer’s application instructions meticulously. Below, we will discuss the proper procedure for applying Thompson’s Water Seal to provide you with the best results.

Why Follow the Manufacturer’s Instructions?

The manufacturer typically knows the product best and provides the most accurate and effective application methods. Ignoring the instructions can lead to uneven coverage, blistering, peeling, or poor adhesion. These issues can not only mar the appearance of your deck but also result in premature degradation of the sealant. Therefore, it is imperative to adhere to the guidelines provided on the product’s can.

Step-by-Step Application Process

Step 1: Preparation

1. Cleaning: Begin by thoroughly cleaning your deck to remove any dirt, debris, and loose material. Use a power washer or a mixture of water and mild soap to scrub the surface. Ensure the deck is completely dry before proceeding.

Step 2: Surface Inspection

1. Check for Moisture: Ensure that the deck is completely dry. A humid or wet surface can lead to improper adhesion and potentially cause the sealant to peel or blister.

Step 3: Application

1. Masking: Apply painter’s tape to any areas that you want to protect from the sealant, such as the edges, corners, and trim.

2. Stirring the Product: Comprehensive stirring is essential to ensure uniformity in the sealant. Follow the manufacturer’s instructions regarding the correct amount of time to stir the sealant before application.

3. Application Technique: Use a high-quality paint roller or brush to apply a thin and even layer of the sealant. Work in sections to avoid drips and runs. Re-apply a second coat if necessary, as per the product’s instructions.

4. Allow for Drying: Follow the manufacturer’s instructions regarding the drying time for each coat. This can vary depending on the thickness of the application and the ambient temperature and humidity. Typically, you should let the first coat dry for several hours before applying the second coat.

Alternative Products and Considerations

While Thompson’s Water Seal is a reliable option, there are other liquid rubber polyurethane products available that offer improved protection and durability. For instance, using a product like WPC Polish can provide longer-lasting protection, sometimes lasting up to 3 years with proper application. However, these products come with a higher price tag and may require more specialized skills for application.

Cost Consideration: While premium products may cost more upfront, they can save you money in the long run by requiring less frequent reapplication. As a design architect, the investment in higher-quality products often pays off in the form of superior performance and aesthetic results.

Conclusion

Applying Thompson’s Water Seal to your deck is a straightforward process if done correctly. By following the manufacturer’s instructions and taking the necessary preparatory steps, you can ensure that your deck remains protected and beautiful for years to come. For those seeking more durable solutions, exploring alternative options like liquid rubber polyurethane can be a worthwhile investment.
