Sealing off your wood with a wood sealer is the best way to preserve your wood. Furniture naturally gets old and wears out, but you can enhance its durability by protecting it with a sealer. Sealing a wood is an easy task, but having the right knowledge about sealers and choosing the right product is not quite an easy task. We have for you, here, the necessary information you need to know about sealers, and also a list of the best water seal for decks products you can find in the market.
Let us examine vital information about wood sealer- how it works, the different types of sealers available, factors to consider while buying, and how to apply.
How It Works
The wood sealer works majorly through penetration. When the sealer is applied to the wood, it soaks the wood and starts to dry gradually. In the process of drying, the sealer begins to harden the wood and fill up every porous part of the wood. The effectiveness of the sealing process is determined by the porosity of the wood. Not just this, it is also determined by the consistency of the sealer.
Do not be deceived that stains and sealers are the same. They are not. Stains are used for coloring the wood, while sealers are used to provide moisture protection.
Types of Wood Sealer
There are two types of wood sealers, namely, water-based and oil-based sealers.
- Water-based sealer: this is the most popular of all sealers due to several reasons. It is less toxic, and it has less odor. The water-based sealer is harder and can give a dark finish that changes the color of the wood. Although this would only happen if you are using an expired can of the product. Another good about this type of sealer is its quick drying time.
- Oil-based sealer: this is a suitable choice for people who pay attention to the appearance of their wood. This sealer brings out the grain of the wood by darkening it and providing a high level of shine. Most wood that looks smooth and shiny, probably have an oil-based finish.
Factors to Consider While Buying a Wood Sealer
When choosing a sealer for your wood, put the following in mind.
- If you need a sealer for your indoor furniture, you may go for a mild-textured sealer. However, a tougher sealer is the best option for sealing an outdoor wood.
- Choose a sealer with reliable UV protection. UV is a significant cause of cracks and peels in the paint. The UV radiation degrades the paint and finishes by drying out the resin component. It is recommended to go for a product that offers reliable protection against UV radiation.
- Your wood is eco-friendly, so should your sealer be. If you are sealing an outdoor wood, then you should get a non-toxic sealer. This will be more accommodating for visitors and friends.
How to Apply
First, before you start the sealing process, ensure you check for the weather forecast to be sure that there won’t be rain for at least two days. Some sealers take time to dry, and the whole work can be messy if exposed to moisture before drying out. Next, prepare a work surface. Clean out the old finish of the wood; be careful no plant is nearby to prevent spillover. Now, find a soft brush to apply the sealer to the surface. Do not use a sprayer because sealers are too thick. Neither should you use a roller; it will leave many marks and streaks on the wood.
