The Benefits of Sealing Hardwood Floors and Why You Should


Published in Business Articles

Installing hardwood floors can cost up to $12,000 for a one thousand square foot area. With such a big investment, you want to be sure you’ve done all you can to get the most life out of them.

That’s why we recommend sealing hardwood floors. Using a sealant helps extend the usage of your hardwood floors because it adds a layer of protection.

Whether you’re refinishing or laying down new flooring, there are many benefits to sealing your wood floors. Read along as we explain how and why you should take this extra step!

When Do You Seal Hardwood Floors?

First of all, if you buy engineered hardwood floors from a retailer as your flooring, they are likely already sealed and finished. You can add another layer for extra protection if you’d like, but know that it has already been done.

If you are constructing your own flooring out of unfinished boards, you will absolutely need to use a sealant. The same goes for if you are sanding floors or refurbishing old hardwood flooring.

How Do You Seal Them?

If you are refinishing your floors, your first step is to have sanded them down. Then, the floors are wiped off with a damp cloth to remove any remaining dust or debris. This is an essential step to make sure the sealant adheres properly to the wood.

After your floors have been sanded, removing the previous finish and sealer, is when you seal your wood floors. Using a microfiber roller, the sealer is simply rolled on. Once the appropriate amount of time has passed and the sealer is dry, is when the finishes can be applied on top.

Reasons for Sealing Hardwood Floors

You would never leave your hardwood floors unsealed and unfinished as raw wood decays. Flooring has to be treated to be of any use inside or outside of the home.

Flooding and Spills

A sealant fills any holes or gaps in your wood and floor and helps it to repel water. If you have hardwood flooring that is unsealed and there is a flood, you’re in for a bad day.

You may be looking at replacing planks or repairing the entire floor. A private flood insurance company can help save your wallet during this process. While sealant isn’t a cure-all, it does stand up to minor flooding and major spills.


Not only does sealed wood hold up against water, but it also protects against staining. Wood is very porous, which is what makes it great for being stained a color that fits your taste.

If you skip the sealing step, it can also absorb other colors. Say, for instance, you spill your wine onto your untreated hardwood flooring. You would now have a wine stain on your beautiful flooring.

Stops Wood Reactions

You never know for certain how wood is going to react to your finish. This is because your wood was once a living thing. It has natural oils and tannins.

A finish applied directly to untreated wood may not mix properly and could cause discoloration and poor adhesion. Sealing provides a base layer so that when you apply the finish it doesn’t sink into the wood and mix with its tannins.

Sealing helps save you money because it is inexpensive and makes it so that your finish isn’t being continually absorbed into the wood. Finish first is a waste of product.

Maybe you like the look of the natural wood color. Using a wood sealant makes it possible to allow the wood to stay its natural color. You don’t have to use a finish after using a sealant.

Most people do because they want it to be a different color. Sealant makes this possible too.

Wood doesn’t react well to grays, whites, and blacks. So, wood sealer opens up an array of color choices that wouldn’t have been a possibility without.

Stops Panelization

Wood naturally expands and contracts. This means that your floorboards do too!

Finish has a way of gluing your floorboards together making it so that the individual boards expand as one big panel. Large gaps then form on either or both sides of the combined floorboards.

This causes an eyesore, and, if it happens with multiple sections, appears like you have floating islands of floorboards. Adding a sealant before your finish keeps the boards separated and breathing on their own.

Wear and Tear

You, your pet, and your family take a toll on your flooring from everyday wear and tear. From pet urine to muddy boots, floors deal with a lot of stress.

However, when you use a sealant, your floors look fresh and new. That extra layer helps mitigate scratches and dings and repels water so you don’t have to spend the extra money replacing boards.

Types of Sealants

There are polyurethane, wax, oil, and water-based sealants. We recommend using a water-based sealer because it is cheaper and is designed to sit on top of the wood instead of soak into it.

This gives you the perfect base to work on without losing excess product. The poly finishes can and should be used on top of the sealer for an even better finish.

Protect Your Investment

You have to decide whether you think adding a sealant is worth the money to protect your hardwood flooring. It is an extra step and an added cost. However, sealing hardwood floors brings significant benefits and gives them a long-lasting life.
