Is It Necessary to Seal Your Concrete Floors?

You’ve probably heard that you should seal your concrete sealing floors. But how do you know if your concrete has been sealed? This article will explain the types of concrete sealers, how they work, and whether or not you should reseal your concrete floor. Here are some tips to keep in mind before deciding whether to seal your concrete floors. Hopefully, these tips will be helpful to you. But do you really need to seal your concrete floors?

Why you should seal concrete

There are many reasons to seal concrete. This material is highly porous and easily absorbs water, oil, and other liquids. Depending on the type of concrete, this can lead to mould, mildew, and even slipping. Sealing can prevent these problems. It will also prevent dirt and oil from building up on the surface and help prevent UV rays from penetrating the concrete. Listed below are some of the reasons to seal concrete.

Generally, concrete is the most common construction material in homes. It is also the most durable. Concrete is used to build bridges, floors, sidewalks, and patios. But it is prone to cracks and degrades when exposed to sun and water. When it’s not properly cared for, it can become weak and break. This is why sealing is a good idea. Properly sealing concrete will extend its life and protect it against the elements.

Sealing concrete is important, especially if it’s a pool deck or driveway. The concrete needs to dry for at least one month before it can be sealed. The temperature of the concrete will vary, so wait until it’s at least 55 degrees before applying the first coat. After a month or two, apply a second coat if necessary. To prevent chemical reactions, it’s helpful to know the type of sealer you’ve used previously. For example, if you used solvent-based sealer on your concrete, you should use a solvent-based or acrylic-based sealer. If you’re applying an acrylic-based sealer, then it’s important to keep the main ingredient the same every time you seal concrete.

Types of sealers

There are several types of concrete sealers on the market today. Acrylic sealers are the cheapest and most common. They are easy to apply, durable, and less expensive than solvent-based sealers. But while they are inexpensive, acrylics can be difficult to remove and cannot be used outdoors or in wet environments. In addition, they produce volatile organic compounds (VOCs) and may turn yellow if exposed to UV light. These toxins may cause chronic health problems.

Interior concrete is porous and is exposed to stain-causing liquids and high traffic. Untreated concrete floors can become damaged or scuffed by minute cracks and holes, and bacteria can grow in these tiny holes. Because interior concrete can be subject to staining and fading, sealing it is essential to preserving the surface for a long time. Additionally, sealers prevent liquid from penetrating the concrete and protect it from normal wear and tear.

Acrylic and silicone sealers are the most common type of concrete sealers. While they require one application, most acrylic and silicone sealers can be applied to a surface within a few hours. However, penetrating sealers require two coats and need to be applied wet-on-wet, meaning the second coat should be applied immediately after the first. And, for those who don’t want to deal with the messy process of cleaning and applying a new coat, you can choose a concrete sealer that’s right for you.

Testing if you need to reseal concrete

When is it time to reseal concrete? The frequency of resealing a concrete driveway will depend on how much wear is occurring to the slab, the type of sealer used, and the climate. Concrete Network suggests resealing every one to three years. If you notice that the sealer has faded in the first year, you may need to reseal the concrete.

One of the most common ways to test the condition of your concrete is to use diluted muriatic acid. However, you may find that the results are inconclusive. It’s better to get an expert’s opinion because moisture content is rarely below 15%. Typically, the moisture content of concrete should be at or below 12% before painting. If you find that the concrete is too moist, you may need to reseal it.


Before you apply a sealer to your concrete, you should test the concrete to determine its stain resistance and other characteristics. The results of these tests should be comparable among different sealers so you can compare them side by side and determine which ones will provide the best protection. This will ensure that you are using the right sealer for your concrete. The best sealers will be able to withstand all types of weather and wear.
