Things To Consider Before Buying A Wood Sealer For Wood Decks

If you’re considering buying a sealer for wood, there are a few things you should think about first.

1. Types of Sealers:

There are two types of deck sealers: water-based and oil-based. Although water-based products are more popular, both types have advantages and disadvantages.

2. Easy To Apply:

There can be a lot of difficulties applying sealers based on oil. As the moisture attempts to evaporate, tiny bubbles and spots may appear on the deck if it is not dry completely when the sealer based on oil is applied. Wood that is overly damp but not wet can be sealed with a water-based sealant.

Oil-based sealant must be applied with brushes, whereas water-based sealant can be applied to the wood by brushing or spraying. Rollers are not commonly used, no matter what material is used for deck sealing.

3. Environmental awareness:

Sealers based on water are better for the environment in general, and they are less irritating for the lungs & eyes when compared to sealers based on oil.

  • Cleanup:

After applying a liquid sealant, you can easily remove brushes and tools. A solvent such as paint thinner is required to remove an oil-based sealant after application.

  • Durability:

It is more common for sealers based on oil cracks or flaws over time than sealers based on water, particularly in extreme weather conditions.

  • Preparation:

When resealing a deck, sealants based on oil typically offer more forgiveness. Products containing oil are usually easier to apply evenly over imperfections or rough woo than water-based products. Before using any Sealer, preparation and cleaning of the deck are essential.

4. Level Of Water Resistance:

Sealers are used on wood decks primarily to keep water out, as this is the leading cause of damage. It is susceptible to warping, cracking, and splitting with temperature and weather changes. It is ideal to choose a water-based sealer that penetrates the wood fibers. Test it with water beads to make sure it’s working. Water protection is adequate if beads form on the wooden surface. Water the wood with a spray bottle. Keeping your deck water-resistant requires sealing pressure-treated wood once a year.

5. VOC Level:

After applying deck sealants, deck sealer, or oil-based stain & sealer combo products, DIYers may experience an irritated nose, headache, or burning eyes that are caused by VOCC fumes. VOCs are often found in deck sealers as solvents. To ensure a long-lasting coating, sealer components must not separate.

The government does not regulate the level of VOCs allowed in deck sealers. Still, manufacturers strive to provide quality products while reducing toxins. In the end, people and the environment benefit from non-VOC sealers emitting less toxic fumes.

  • Low-VOC:

There is a limit of 50 grams of VOCs per (g/L) in in-deck sealers labeled “low-VOC.” That compares with contains up to 300 grams of high-VOC sealants

  • No-VOC:

Often referred to as “VOC-free,” these deck sealants have few or no volatile organic compounds. There is approximately five g/L or less of VOC in no-VOC products. When paints and sealers contain low VOCs, we expect improved durability, fewer reapplications, better edge protection, thicker coatings, more accessible application, and better air quality after sealing. It will help if you also choose a deck paint with low volatile organic compounds (VOCs) so you don’t inhale toxic fumes.

6. Degree Of Uv Protection:

All living things, including wood, can be damaged by the sun’s ultraviolet light (UV) rays,

which beat down daily. Fading, cracking, and splintering are signs of that wood damage. 

The added ingredients in deck sealers, like zinc particles, Protect against UV rays.

 Although they break down quickly, these ingredients usually achieve long-term stability. That can even happen in a few months when the weather is warm and sunny.

To ensure optimal UV protection, apply a simple water-based sealant before summer starts. The durability of deck sealants varies, so it recommends that you reapply them before the summer season begins.

7. Color:

The color of the sealer is often chosen to match the wood (we offer sealers for staining mahogany wood) or complement the home, or the sealer is semi-transparent.

If you are planning to paint a pressure-treated wood deck, it is wise to start by painting a small area with a light color. Consider getting a sample of the wood deck and having the hardware store recommend the type and color of the sealer that will work best for your deck.

If you change your mind, we recommend applying a light tone. The darker tones absorb more heat, increasing the temperature on your deck, so you may only be able to use it in the early mornings or late afternoons. Additionally, if you regularly get leaves or other foliage on your deck, the stain these cause won’t be as apparent.

8. Drying Time:

Depending on the deck sealer, drying time may vary. Depending on the humidity level and ambient temperature, it may take one to five hours for a garment to be dry to the feel.

  • Water-Based Sealant:

Water-based sealers typically dry in one to three hours when it is between 60 and 90 degrees Fahrenheit and Moisture content is at or below 50%. A 2nd coat can be applied after the sealant has dried to the fee. Sometimes, the sealer may take up to 24 hours to cure (when it is dry enough for furniture to place or for you to walk).

  • Oil-Based Sealant:

About 24 hours after applying the first coat, apply the 2nd coat. The drying time of oil-based sealant is usually between four and twelve hours. Fast-drying additives are found in newer oil-based sealers, which may reduce the time it takes to recoat after drying. There is a possibility of a 72-hour cure time.

 

9. Moisture Resistance:

It is possible for deck sealers, like deck paints, to contain mildew ides, chemicals that kill fungal spores. White or black splotches on wooden decks caused by mold or mildew are unsightly and difficult to remove in damp climates. If you live in rainy or high-humidity weather, you should find a fungus- and moisture-resistant sealer.

10. Coats:

Some deck sealers can be applied in a single coat, while others require two coats for maximum performance. A single-coat sealer can save users a lot of time, although it will cost them more.

The surface can have a rough feel when using a water-based, penetrating sealer. In this case, the wood grain swells and pushes upward due to the moisture in the sealer. As the wood dries, the grain remains slightly higher in some places.

Applying the second coat of sealer without lightly sanding the surface with 240-grit sandpaper is possible. However, some people may prefer its rougher texture.

Read the instructions carefully before applying the product, as curing times vary. Others recommend waiting a certain number of hours before applying a second coat, usually between two and eight hours. Sandpaper shouldn’t be rubbed over the wood with pressure. A smooth deck surface is achieved by sealing the wood with the first coat, resulting in a soft second coat.

How To Apply Wood Sealer On Wood Decks For The Utmost Results?

Before applying the sealer, rinse your deck thoroughly to ensure it is highly effective. Ensure all Mold, debris, and dust are removed. We must keep a few things in mind before we discuss Sealing a wood deck.

To properly absorb the sealer into the wood, it needs time. The finish will dry too fast if applied in full sunlight. It is also best to wait a few weeks before staining a newly constructed deck if you use treated wood. The stain will absorb better if the wood has completely dried. It’s time to get started!

Step 1: Verify The Weather Forecast

Before applying deck sealant, it is necessary to make sure that the deck has been dry for at least 2 days at a temperature between 50 and 90 degrees Fahrenheit. In this way, you will provide the highest quality sealing.

Step 2: Clean The Decks

Keep the plants, furniture, and other furnishings scattered throughout your deck from being sealed. Because Sealing any surface with a sealant will trap moisture inside the container and prevent it from leaving. That can rot, damage the wood frame or flooring below, and increase bacteria growth.

 

Step 3:Use Sand (If Needed)

Make sure your deck is properly sanded before sealing it. In many cases, sanding is necessary, but it takes time. If you want to sand faster, use a Palm scrubber or pole scrubber to sand along the grain. To avoid inhaling sawdust while sanding, wear a respirator.

Step 4: Debris Removal

After sanding, removing loose debris from the deck is essential. Clean all cracks of decks and allow them to dry completely. If there are still any dry spots, wait until these areas are thoroughly dried before continuing. Apply a coat of wood sealant once the deck is completely dry.

 

Step 5: Sealer That Stirs

Make sure the sealer is thoroughly mixed before applying it. To avoid bubbles, it is essential to keep the sealer intact.

 

Step 6: Applying The Sealer

Use a brush, sprayer, or roller, to apply a thick coat of paint over a 2- to 3-board area. It is better to apply a 2nd thick coat than a single thick coat so that you may add another light coat later. In addition to back-rolling, creating a good coat may be necessary. One person must apply a sealant, and another must spread puddles with a broom or roller.

 

Step 7: Repetition And Fine-Tuning

It recommends that step 6 be repeated throughout the deck. The finer the paintbrush, the easier it is to seal cracks, railings, and steps.

Step 8: Let Dry It

When using your deck, you should ensure that it has completely dried before using it. That will help avoid possible water damage and other issues.

Reasons For Using Deck Sealant On Wood:

Deck sealant protects the wood from moisture, dirt, and other contaminants. It is typically applied as a coat of sealant on the wood surface and then left to dry. Deck sealant can be used to protect the wood from the harmful effects of the elements, and it can also help improve its appearance. Listed below are a few reasons why you should use deck sealant on your wood:

 

  • Wood Sealer Prolongs The Life Of Your Deck:

There are many enemies on your deck, including rain, wind, sunlight, and heat. Your deck, porch, or patio will deteriorate faster if exposed to these conditions for an extended period. Your deck is protected from the elements by using a wood stain sealer.

  • Preserve Affordable Decking Lumber:

There is no doubt that pine is an affordable softwood, but it requires frequent repairs or replacements. Pressure-treated pine is often used for decks by homeowners. Insects or rot can be prevented by using a wood sealer.

  • Preserves The Beauty Of The Wood:

There’s no way that’s an overstatement since even stains alter the color of wood to some degree. Stains can preserve the natural grain pattern of the wood, but they will still make it appear darker. Applying a transparent stain to your deck wood is best if you love its natural grain pattern and color.

  • Add An Attractive Sheen:

The great thing about sealants nowadays is that they come in various types. It is possible to get almost invisible sealers. If you want to add a stylistic sheen to your deck without altering its natural beauty, you can apply a seal that adds a stylistic shine.

  • Protects From Moisture:

To prevent water from penetrating the wood, deck sealants penetrate deep within the planks. A film is also applied to the surface to prevent water from penetrating the wood.

The dual-action protection prevents wood rot, fungal growth, mildew, and mold on your deck, which can damage it.

  • Sealing Is Cost-Effective: 

Sealing your deck is one of the most cost-effective options if you decide to do the project yourself. Although you will need to hire a contractor to complete the job, it is still an affordable option compared to staining and painting.

  • Protector Against Rot:

Over time, wood degrades. Rotting is a severe problem for timber. It is not only unsightly but dangerous to have a rotted wood deck. Sealing your deck’s wood prevents injuries and protects it from rot. There is no way to reverse wood rot. To prevent this from happening, you must take the necessary steps.

  • Sealers Can Be Used In Tandem With Stains:

It is popular among deck owners to stain their decks, as the added pigmentation provides coloration and protects them from UV rays. While stain protects your deck from UV rays, it doesn’t offer much else in deck protection. To protect against weather, water, and UV rays, you can use a combination sealer that contains pigmentation.

  • Sealing Can Save Your Wood:

Sealing offers more excellent protection than painting and staining. A sealant is often recommended as the finishing touch when restoring an old, damaged deck since it protects the wood from further damage.

FAQs:

Which Is Better For A Wood Deck, Seal, Or Stain?

Your wood’s needs will determine which one is best for you. Stains are the best choice if you want to change the color of your wood. A stain is better if you want to keep the wood color and protect it from the elements for as long as possible.

Though opinions differ on whether staining or sealing is more important, it makes sense to choose a wood with a color you’re already happy with and seal it to protect it and get the most life out of it. The deck will need to be repainted every other year or two.

Do You Need To Sand The Deck Before Sealing?

You must sand your deck before sealing it if you are considering sealing it. You must perform this step to prevent ugly blemishes or marks from appearing on your newly stained or closed deck.

The deck should be sanded before it is sealed to avoid unnecessary damage and keep your finish looking great for years to come. This step is essential for a high-quality refinishing job. The purpose of sanding a deck before staining is to provide it with a smooth, clean, and absorbent surface so the stain and paint will adhere more easily.

Is Water-Based Or Oil-Based Deck Sealants Best For A Wood Deck?

Each has its advantages and disadvantages. Choose one best suited to your deck, or determine if one’s advantages outweigh its disadvantages.   

A water-based deck sealant is safer for people and animals around the deck and more eco-friendly. Furthermore, these dry much faster. Water and detergent are usually all that’s needed to clean them.

It is more durable and offers excellent protection than water-based sealers. Compared to oil-based products, these products are less stable. Additionally, they contain toxic chemicals. Apply them according to the manufacturer’s instructions for the best results.

Finally, expect a more extended drying period and higher prices than water-based alternatives.

Does Sealing A Deck Make It Last Longer?

High-quality sealers are the key to extending the life of a deck and protecting it from the elements. The wood sealer protects your deck from weather damage, preventing moisture and fungi from infiltrating. Additionally, sealing can enhance the natural grain of your lumber by adding richness and depth.

Protecting your deck isn’t just about keeping it looking good but also preserving its structural integrity. Rain and wind exposure can cause rotting and peeling (a condition called biofouling), which could lead to severe problems like rot. A high-quality wood sealer will keep your deck healthy and robust for years.
