What to Know Before You Buy
- Deck Type: Understand your deck’s specific needs by considering the type of wood and its current condition.
- Opacity: Sealers come in different opacities from clear to solid. How much of your wood’s natural grain do you want to show through?
- Waterproofing: A crucial aspect of a sealer is its ability to repel water. Make sure the product you choose has excellent waterproofing properties.
- UV Resistance: Prolonged exposure to the sun can fade and damage wood. UV-resistant sealers help maintain the color and integrity of the deck.
- Ease of Application: Check if the sealer you’re considering is easy to apply and whether it needs a primer, saving you time and effort in the process.
- Eco-Friendliness: If environmental concern is high on your list, look for sealers with low VOC and those that are safe for people, pets, and plants.
Factors to Consider Before Buying
- Climate: Your local climate plays an enormous role in the choice of the sealer. Wet and humid climates may require different protection compared to dry and sunny areas.
- Regular Maintenance: Some sealers demand recurrent application, while others last longer. Determine your willingness for upkeep to help choose the suitable sealer.
- Color Retention: If preserving the original look of your wood is critical, consider sealers with color retention properties to prevent graying and fading.
- Drying Time: Consider how quickly the sealer dries, which directly affects the deck’s usability after application.
- Longevity and Durability: Investigate the life span of the sealer. A lasting sealer may cost more upfront but can be more cost-effective in the long run.

Frequently Asked Questions
What is the best type of deck sealer for my wood deck?
The best type of deck sealer depends on the type of wood, the climate you live in, and the look you want to achieve. A clear sealer is best for showcasing the natural beauty of the wood, while tinted or semi-transparent sealers can provide added color and UV protection.
How often should I reapply deck sealer?
Most deck sealers need to be reapplied every one to three years, but this can vary depending on the sealer type, the weather exposure, and the deck’s usage. Always check the manufacturer’s recommendations for your specific product.
Can deck sealer be applied over painted or stained wood?
Deck sealer can usually be applied over wood that has been previously stained, as long as the stain is compatible and the surface is properly prepared. However, sealers generally do not adhere well to painted surfaces.
What is the difference between deck sealer and deck stain?
Deck sealers are primarily designed to protect wood from moisture without changing its appearance, whereas deck stains provide color and may also include sealing properties. Some products combine staining and sealing for a two-in-one application.
How do I prepare my deck for sealing?
Preparing your deck for sealing involves cleaning it thoroughly to remove dirt, grime, and any previous coatings that are peeling or flaking. This may include scrubbing, power washing, or using a deck cleaner. Allow the wood to dry completely before applying the sealer.
Is it better to apply deck sealer with a brush, roller, or sprayer?
The application method can depend on personal preference and the type of sealer used. Brushes are good for precision, rollers cover large areas quickly, and sprayers are efficient for even coverage. Some sealers are formulated for specific application methods, so refer to the instructions.
Can I apply deck sealer in any weather?
No, weather conditions can significantly affect the application and drying of deck sealer. Avoid sealing your deck in the rain, in extreme temperatures, or under direct sunlight. Optimal conditions are typically dry and mild temperatures.
Will deck sealer make my deck slippery?
A properly applied deck sealer should not make your deck slippery. However, certain sealers might create a slick surface when wet. Look for sealers with non-slip properties if this is a concern.
What is the best way to maintain my sealed deck?
Keep your deck clean by sweeping it regularly and washing it with appropriate cleaners periodically. Remove debris and leaves, which can trap moisture, and reapply sealer as recommended by the product’s manufacturer.
Are there eco-friendly deck sealers available?
Yes, there are eco-friendly deck sealers that use water-based formulas and contain low VOCs (volatile organic compounds). These options are less harmful to the environment and safer for pets and humans during application.
