Thompson’s Water Seal is one of the best products protecting outdoor surfaces and preserving our assets. But, in some cases, Thompson’s Water Seal does not dry after its allotted drying time.
If you’re into the same concern, let our expert woodworkers explain this matter in detail, along with the possible causes and tips to get past this issue successfully.
Thompson Water Seal Drying Time, Explained
Like any sealant, Thompson’s has to have sufficient drying time. As a matter of fact, within approximately 24 hours, without any hiccups in temperature or humidity, the water sealant can dry properly.
You must note that drying time ultimately depends on the nature and the certain materials on the surface you’d coat. This water seal is ideal on pressure-treated lumber, but applying it on wet wood is not recommended.
Can You Apply Two Layers of the Water Seal?
Ideally, one coat of water sealant is all you need. But in some instances, you would feel the need to recoat it.
This does not necessarily require you to use mineral spirits or paint thinner. One thing you can do before applying two coats is to make sure to completely dry the previous layer. After that, you can now recoat Thompson’s water seal.
Thompson's Water Seal Not Drying: Top Causes
Many factors can affect why this water sealant does not dry. So, let us carefully scrutinize the leading causes of this concern:
High Humidity Levels or Cold Temperature
Temperature is one of the factors that influence the drying time of a water sealant.
High humidity  means much moisture is around. Moisture should not be around when applying a water sealant because it can stretch the time needed for the wood surface to dry.
But if you live in places with too much moisture in the air, you can wait 2 to 3 days for the wood or brick surface to seal.
Give your surface time to dry after your first coat, second coat, and more, if needed.
Insufficient Drying Time
Time can be another factor affecting the drying time. Do not rush it; allow the surface to give sufficient time to dry, especially the Thompson’s Waterseal products, to not have sticky residue or water bubbles.
Moreover, applying an excessive quantity of water seal can impede proper evaporation and hinder the sealant from effectively penetrating and protecting the wood surface.
It is crucial to apply the appropriate amount of water seal according to the manufacturer’s instructions to ensure optimal drying and performance.
Applying on a Pre-Sealed Surface + How to Know if it's Already Sealed
One thing to do before using the water seal product is to check if the surface you are applying has undergone sealing.
To know just that, you can do a water splash test to see if the water beads stayed on the surface or absorbed it. If the surface you tested just repels water you just splashed, then it is safe to say that it’s a sealed surface.
Applied Way Too Much or Excess Sealant
Applying excess amount of sealant can prevent the surface from drying quickly. Consider not using too much water seal to ensure the surface can dry completely as fast as possible. Keep the approximate figure you use in check, and keep your coats as thin as possible.
Applying Thompson’s water seal multiple times with coats that are thinner is better than one thick coat that can cause bubbles and stay sticky.
Tips to Avoid and Fix Water Seal Drying Issues
Tip #1: Wipe Off the Excess Sealant Right After Noticing It
Before you think you have messed up, make sure to remove the excess amount of sealant right away. Use a soaked rag in soapy water to wipe off the area, which could be why the seal does not dry.
Tip #2: Spare More Drying Time (Up to a Week)
Let the sealer dry for about 24 hours to an entire week. This way, you are assured that the previous coat on the surface has dried before you apply the second coat if needed.
Tip #3: Speed Up the Drying Process Using a Fan
When in a hurry, one way to boost the drying process is by using a fan. It will help the surface to dry sooner, speeding up the process.
Tip #4: Always Read the Product’s Instructions
Always read the instructions carefully before you apply the water seal. This also helps prevent applying excess amount of sealant by following the manufacturer’s recommendation.
Tip #5: Keep Your Coats Thin
Keeping your coat thin when applying water sealant is one way to ensure the application is good. This way, you can control how much product you use and help the water seal dry fast.
Tip #6: Use a Sprayer to Apply the Sealant - The Best Way to Apply Thompson's Water Sealer
You can use different materials to apply your sealer. According to our test, the best way to spread the sealer is to use a sprayer, which is much faster and very efficient.
You can control how much you’re using, and you can apply thin coats to the surface, causing less time to dry.
Tip #7: Schedule Your Sealing Project During the Summer
Consider scheduling your sealing projects during the summer when the weather is warm to avoid excess waiting time for the sealant to dry.
Tip #8: Test the Wood or Concrete Before Sealing
Always make it a habit to test your wood or concrete before sealing it. Testing is essential to save time and resources before doing anything. It would also keep you from asking why your seal does.
