Basement Floor Sealer - How and Why Do You Seal a Concrete Floor?
A basement floor sealer is a product that is applied to concrete in order to protect it from water and other elements. It is an important step in protecting your concrete floor, and it is something that you should consider if you have a basement.
In this guide, we will discuss the benefits of using basement floor sealers and how to apply them properly.
What is Basement Floor Sealer?
A basement floor sealer is applied to concrete surfaces in order to provide protection from weather, water, and traffic. Basement floor sealers come in both solvent-based and water-based varieties, and they can be either penetrating or film-forming.
This type of sealer is important because it helps to prevent water and other liquids from seeping into the concrete and causing damage. Water can cause the concrete flooring to crack, and it can also lead to mold and mildew growth.
Sealers work by creating a barrier on the surface of the concrete that repels water and other liquids. They are typically clear or have a slightly milky appearance, and they can be applied with a brush, roller, or sprayer.
8 Different Types of Basement Floor Sealers
There are eight different types of basement floor sealers that you can choose from:
1. Penetrating sealers
These sealers are designed to penetrate deep into the concrete to provide long-lasting protection. They will not change the look or color of the concrete and can be used on both interior and exterior surfaces.
2. Water-based sealers
These types of sealers are usually clear or have a slight tint to them. They penetrate deep into the concrete to form an invisible barrier against water and other liquids. Water-based sealers are also breathable, which prevents moisture from being trapped beneath the surface of the concrete.
3. Solvent-based sealers
The solvents in these sealers evaporate as they dry, leaving behind a very thin film of sealer. This type of sealer penetrates deeply into the concrete to provide excellent wear and stain resistance.
4. Epoxy coatings
Epoxy coatings are a thick sealer that is applied to the floor with a brush or roller. They provide a durable, waterproof barrier that protects the concrete from spills and stains. They are also easy to clean and maintain.
5. Urethane coatings
Urethane coatings are a popular choice for sealing concrete floors in basements. They provide a durable, moisture-resistant barrier that can extend the life of your concrete floor. Urethane coatings are available in both clear and pigmented versions.
6. Polyurethane coatings
A polyurethane coating is a liquid that is applied to the concrete and cures to form a thin, hard, durable film. This type of sealer is typically used on garage floors and other high-traffic areas because it can resist abrasion and chemicals.
7. Acrylic sealers
This is a water-based sealer that will penetrate into the concrete and provide good protection against stains. It is also a very durable sealer that will last for many years. This type of sealer can be applied with a brush or roller and does not require any special equipment.
8. Silicone sealers
Silicone sealers are the most expensive option and provide the best moisture barrier. They can last up to 30 years if applied correctly.
How to Prepare Your Basement Concrete Floor for Sealing
It is important to properly prepare your concrete floor before applying a sealer. The first step is to clean the floor and remove any dirt, grease, or oil. You can do this by pressure washing the surface or using a degreaser.
Once the surface is clean, you will need to repair any cracks or holes in the concrete. You can use a concrete patch or epoxy to fill in the holes and cracks.
After the repairs have been made, you will need to etch the concrete. This step is important because it creates a rough surface that allows the sealer to adhere properly. You can etch the concrete with muriatic acid or a power washer.
Once the concrete is clean, dry, and etched, you are ready to apply the sealer.
When Should You Seal Your Basement Concrete Floor?
It is best to seal your concrete floor in the spring or summer when the weather is warm and dry. This will allow the sealer to properly cure and will provide the best results.
Sealing your concrete floor is an important step in protecting your investment and extending the life of your floor.
How Often Should You Seal Your Basement Concrete Floor?
You should seal your concrete floor every 2 to 5 years, depending on the type of sealer that you use and the location of your concrete floor. If you live in an area with a lot of snow and rain, you may need to seal your floor more often.
You can tell if your floor needs to be resealed, if the sealer is starting to wear away or if the color of the concrete has changed. If you put flooring in your basement, you won’t be able to seal it again. Which most likely won’t be a problem.
Signs Your Concrete Basement Floor Needs Repair
There are a few signs that you can look for to determine if your concrete basement floor needs repair:
1
Cracks
Small cracks in the concrete are not always a cause for concern. However, if the cracks are large or numerous, they can weaken the structure of the floor and should be repaired.
2
Discoloration
If you notice any discoloration on your concrete floor, it could be a sign of water damage. Discoloration can also be caused by efflorescence, which is a white powder that forms on the surface of the concrete when water evaporates.
3
Stains
Stains on your concrete floor can be caused by leaking pipes, spills, or other sources of water. If you notice any stains, you should have the floor inspected for damage.
4
Holes
Holes in your concrete floor can be caused by wear and tear, or they can be the result of an impact. Holes should be repaired to prevent further damage to the floor.
5
Mold and mildew
Mold and mildew can grow on concrete floors that are damp or have leaks. Any mold or mildew should be removed to prevent it from causing health problems.
6
Loose or crumbling concrete
If you notice that the concrete on your floor is loose or crumbling, it should be repaired as soon as possible. Loose or crumbling concrete can be a safety hazard and can cause further damage to the floor.
How to Apply Basement Concrete Floor Sealer
Once you have chosen the type of concrete sealer that you want to use, it is important to apply it properly. Here are the steps that you should follow:
- Clean the concrete - The surface of the concrete must be clean and free of dirt, dust, oil, and other contaminants before you can begin sealing it. You can do this by using a cleaner or degreaser.
- Apply the sealer - Use a brush, roller, or sprayer to apply the sealer in a thin coat. Be sure to avoid puddles and pooling.
- Allow the sealer to dry - The sealer will take several hours to dry completely, so be sure to allow enough time for it to cure before you walk on it or place any furniture or appliances on it.
If you follow these steps, your concrete floor will be protected from water and other elements.
If you’re worried about performing this task successfully, you should call a professional to do it effectively.
5 Causes of Concrete Floor Damage
There are a number of things that can cause damage to your concrete floor. Here are the five most common causes:
1. Moisture
It’s the enemy of every homeowner. It can cause all sorts of problems, from mold and mildew to wood rot and structural damage. And when it comes to your home’s foundation, moisture can wreak havoc. That’s why it’s so important to make sure your basement is properly sealed.
2. Waterproofing failure
One of the most common problems basement floors face is a lack of proper sealing. When you finish your basement, it’s important to seal the concrete floor with a good waterproofing sealer.
3. Drainage problems
Drainage problems are the number one reason why homeowners have their basement waterproofed. Without a proper drainage system in place, water will find its way into your basement through cracks and other openings.
4. Tree roots
As trees grow, their roots spread and can cause cracks in your foundation or basement floor. Water can seep through these cracks and cause serious damage to your home. A sealer will help prevent this by creating a barrier between the roots and the concrete.
5. Settling
When your house settles, it can cause cracks in the foundation. These cracks can let water seep in and cause mold or mildew to grow. By sealing your floor, you can help prevent these cracks from forming and keep your basement dry.
