1. Before You Apply Thompson Water Seal
Before getting started on any project, it’s best to clean your workspace. An organized surface increases your productivity when applying the sealer for the first time.
Productivity is shaped by your surroundings; that’s why nobody likes to work in a messy environment. Let’s see how to prepare before you apply Thompson water seal…
Clean the Surface
Things you’ll need:
- A microfiber cloth or a rag to clean the surface
- Water to dampen the microfiber or the rag
Steps to take:
- Dampen the rag or the microfiber in water.
- Rub the material against the surface back and forth.
- Let the surface dry.
Cleaning an Unfinished Wood To Apply Thompson Water Seal
Before you apply Thompson water seal, use a dry microfiber cloth or rag to clean the surface of an unfinished wood deck.
Keep in mind that using a wet microfiber cloth to clean the surface of an unfinished wood could make the wooden boards warp or get damaged.
To check if your wooden deck is finished or not, add a drop of water on its surface. If it absorbs the water drop and leaves a mark, your deck is unfinished.
Steps to take:
- Rub the dry microfiber cloth against the surface back and forth.
- Keep doing this until there is no dust residue left.
- You can also use a soft broom to get rid of the dust or debris.
2. Apply Thompson Water Seal On The Clean Surface
When you apply Thompson water seal, it’s up to you whether you want to use a sprayer or a paint pad. A garden sprayer makes the job easier, but if you don’t have access to one, a piece of cloth or even a small brush could work just fine.
Things you’ll need:
- Thompson's water seal
- A garden sprayer to apply the sealer, a small brush, or a piece of cloth
- Long sleeves, pants, safety glasses, a mask, and gloves.
Steps to take:
- Put on your protective gear before applying a Thompson water seal with a sprayer.
- Take off the plunger tube.
- Mix the product well and fill the spray can with Thompson's water seal.
- Replace the plunger tube.
- Slightly tighten it down until you feel resistance. Do not overtighten it.
- Now you need to depress and release the plunger.
- Pump it up until you feel resistance.
- Do not over pump once you've felt resistance.
- Spray Thompson water seal all over your deck.
- Let it dry for up to 24 hours.
If you’re not using a pump up garden sprayer, use your piece of cloth or brush directly in the sealant can, and then apply it to the deck surface.
The process may take longer than with a sprayer, but the results will be similar.
Using a Paint Pad
Depending on your project, you may want to use a paint pad, a piece of cloth, or a roller to apply your product.
Using a sprayer is definitely the fastest way to get the job done, but there are some alternatives if you don’t want to spend money on a sprayer.
Things you’ll need:
- A paint pad to soak it into the sealer
- Thompson's water seal
Steps to take:
- Pour the sealer into a deck.
- Dip the paint pad into the seal.
- Bring the seal onto the tray area.
- Start at one corner and work from one end to another.
- Apply the sealer parallel to the deck boards.
Wait For The Water Seal To Dry
Give your Thompson’s water seal at least 24 hours to dry thoroughly. Depending on the weather, drying time may vary.
Keep in mind that if you want to apply latex paint over it—you should give the sealant at least 45 days to settle properly.
