Moreover, it will help to prevent molds or wet and dry rot. Thanks to naturally-sourced ingredients, it won’t leave harmful residues in water and soil, too.
We also like its easily cleaned up and fast-drying ability after application by using water. The protection which is up to 5 years even makes it more valuable.

When Should You Seal Your Deck?
Now you may wonder when is suitable for sealing your deck. Indeed, the best time for you to perform deck sealing is the spring, summer, and fall. The weather in these seasons is ideal for almost all places.
In this case, there are also some points you should pay attention to:
- For clearer sealer, the wood surface as well as air temperature should be more than 50°F throughout the application and drying process.
- For stain, that surface, as well as air temperature, must be from 50°F to 95°F during the mentioned process.
- There must be no rain for 24 hours or more after finishing the application
- You must dry your deck surface for 48 hours before starting the application
To check whether the deck is protected or not, you can conduct a simple test. Let’s splatter some water drops onto its surface and wait some minutes. If the water beads up and remains atop that surface, your deck is still okay.
In case the water soaks deep into your wood, it may be a sign of wood twisting, splitting, or rotting. Don’t forget to check more carefully by performing that test in some other areas of the deck!
Should You Seal Your Deck After Power Washing?
Do you know that power washing is among the most effective methods to make a wood deck clear?
When washing, you should use deck detergent to saturate the deck first. Then, you wait for at least 15 minutes and start power washing later. Be sure to follow the directions for your power washing tool.
So, is it possible to seal the deck right after power washing?
After finishing that power washing work, let your deck dry completely to ensure the deep sealer penetration.
Let’s wait for around 24 hours before applying deck sealers. In the case of cold or humid weather, you should wait for at least 48 hours.
How to Seal a Deck
Now, it’s time for sealing your deck! Here are simple instructions you may follow to finish your task:
Step 1: Cover the Areas
First, you use plastic sheeting or tarp to cover the grass, plants, and other vegetation around your deck.
Don’t forget to cover walls, windows, and other surfaces below or near your deck. This task will help to protect all of them from the deck sealer.
Step 2: Prepare for Cleaning
Second, sweep your deck to remove the dust, dirt, and debris. Then, stir or shake the wood cleaner, following the direction of the manufacturer. Later, add the cleanser to your sprayer.
Step 3: Wash the Deck Railings
Use the garden sprayer above to spray a small area of deck railings. Remember to wash small places at the same time so that you may rinse and scrub your deck before the cleaner dries.
Then, let the wood cleaner sit for around 10 minutes, or as directed. Next, scrub the deck railings by using a scrub brush. Then, use a hosepipe to spray the areas with clean water. Let’s repeat those steps for the rest!
Step 4: Wash the Deck Boards
Now, let’s use the same methods in step 3 and apply for about 15 square feet of deck boards each time. Be sure to make your deck dry for around 48 hours.
Step 5: Inspect the Fasteners
Check your whole deck to find out raised or loose nails and screws, and drive new ones below the wood surface by using a hammer and drill.
Don’t forget to use sandpaper or sharp knife to remove splinters and other hazards. During the drying time after cleaning, you can wipe away all of sanding dust as well.
Step 6: Seal the Railings
You should follow the product directions to apply the sealer to your deck railings. Here, a paintbrush will be ideal for tight spots and corners, while a paint pad will work on larger faces of railings.
You can also take advantages of a sprayer to apply a sealer. Let’s apply an even sealer coating to surfaces, performing small areas, and keeping wet edges. After finishing, check one more time, and wipe up the excess with a clean rag.
Step 7: Seal the Deck Boards
Finally, you can apply the sealer to your deck boards by using similar ways in step 3. You will need some applicator such as a paint roller, paint pad, paintbrush, and garden sprayer.
Start your job from the deck’s far corner to the exit point. Then, keep the sealer dry for at least 48 hours before using that deck. This period also depends on your product and conditions.
How Long does Deck Sealer Last?
It depends on the effect of sunlight as well as some precipitation elements. Some individual decks also need yearly maintenance.
So, the deck sealer’s color should be dark enough to prevent sun damage. Plus, that deck sealer product should let your wood fully dry when it gets wet. If so, an ordinary deck sealer may last up to four years.
However, if there are continuing issues with that deck sealer’s coating, you had better inspect and replace your deck boards if needed.
How Often do You Need to Seal Your Deck?
This case also depends on the surrounding conditions, the deck use, and the finishing product.
For instance, some wood types in direct sunlight may dry out and fade while other types in humid places may grow fungus spores.
Those issues require your care bi-annually or annually. Overall, most deck sealers should be renewed every one to three years.
Those are the best deck sealers in the recent market and some related aspects related to deck sealing.
Hopefully, the detailed reviews above will assist you guys in selecting a proper deck sealer for your wood projects. Don’t forget to share this post broadly! See you in the next one!
