Do You Have To Seal Stained Concrete: 4 Factors [Important]

Last Updated on January 19, 2023

When it comes to beautifying and protecting your concrete floors, patios, and other surfaces, sealing is an important step that should not be overlooked. Sealing stained concrete is essential for a variety of reasons from preventing moisture-related damage to enhancing the aesthetic appeal of the surface beneath.

There are a few preparation steps you should take before applying the sealer, including cleaning and repairing any damaged areas and allowing the surface to dry completely. The type of sealer chosen also matters as there are different kinds available for different purposes. From acrylics to polyurethanes and epoxies, finding the right sealer for your particular project can help ensure desired results.

Applying a thin layer evenly over the entire surface is key in order to properly protect it and keep it looking great. And finally, determining how often sealed stained concrete should be re-sealed depends on many factors such as climate conditions and how heavily trafficked the area is.

The Need for Sealing Stained Concrete

Why is it Necessary to Seal Stained Concrete?

Protection from Moisture and Weather Damage:

It is essential to seal stained concrete in order to protect it from moisture and weather damage. Moisture can seep into concrete and cause the surface to become damp, which can cause the paint or sealant used to fade, crack, or peel over time.

Sealing the concrete helps keep out water and other liquids that could potentially damage the surface of the concrete. Additionally, sealing the concrete will help prevent dirt, dust, and debris from settling into it, reducing staining caused by these particles.

Sealing will also help protect stained concrete from UV radiation exposure due to direct sunlight. Without proper protection from UV rays, outdoor stained concrete surfaces may experience discoloration or fading over time. Lastly, sealing protects against temperature fluctuations that can result in warping or cracking of the surface if left unprotected.

Enhanced Aesthetic Appeal:

The aesthetic appeal of a space is greatly improved when stained concrete is properly sealed. Sealing stained concrete adds a glossy finish that enhances its color vibrancy and depth while also giving it a clean look that will last for years with proper maintenance.

Without sealing, stains can become dull-looking or start to fade away as time passes. Additionally, sealing provides an extra layer of protection against spills and stains which helps maintain its beautiful look longer than if left unsealed. 

Furthermore, sealing improves the overall texture of stained concrete surfaces by creating an even finish across all areas of the surface instead of just patches with different levels of glossiness or sheen from one area to another.

This uniformity helps create a unified look for any interior or exterior design theme which further contributes to an aesthetically pleasing environment for homeowners and businesses alike.

What Type of Sealer Should Be Used for Stained Concrete?

Different Types of Sealers for Different Uses

When choosing a sealer for stained concrete, there are several different types that might work depending on the specific needs and conditions of the area where sealed concrete will be used. It’s important to note that some sealers are designed for interior applications or exterior use only.

For example, acrylic sealers are often used indoors because they provide a glossy finish that is easy to clean and maintain but can yellow over time if exposed to sunlight; while polyurethane or epoxy sealers are generally recommended for outdoor use because they provide more robust protection against UV rays and water damage.

Additionally, some sealers are better suited for high-traffic areas since they create a thicker film on the surface which prevents wear and tear over time. 

Comparing Acrylic, Polyurethane and Epoxy Sealers

Acrylic Sealers: Acrylic sealers produce an attractive glossy finish while providing some degree of protection against staining There are both water-based (WB) and solvent-based (SB) acrylics available; WB acrylics dry faster but typically don’t last as long as SB acrylics which take longer to dry but offer more protection against staining over a longer duration.

Acrylics can also be tinted or colored with certain dyes or tints in order to create a customized look that matches or complements the surrounding decor. 

Polyurethane Sealers: Polyurethane sealers penetrate deeply into the substrate creating a hard protective film that is both bolder in coloration than other coatings such as epoxy and clear urethanes but also offers an impressive level of protection against UV radiation oil stains spills etc., making them ideal for exterior use.

They do require frequent reapplication however in order to maintain their protective qualities and must be applied by professionals due to their strong fumes and pungent odors when working with them. 

Epoxy Sealers: Epoxy seals have become increasingly popular in recent years due its ability to provide superior adhesion durability stain resistance chemical resistance abrasion resistance impact resistance along with excellent color retention even under extreme weather conditions; all making them ideal for applications where ultimate performance is required such as high traffic areas commercial settings etc.

Additionally epoxies come with additives such as metallic flakes quartz etc., which provides an extra decorative element thus giving them an edge over other coatings when it comes down aesthetic value . However epoxies do dry slower than other coatings making them difficult apply quickly along with having limited color choices compared most other coatings .

Preparation Steps Before Sealing Stained Concrete

Preparation Steps Before Sealing Stained Concrete

Clean and Repair Damaged Areas

Sealing stained concrete is an important step for protecting the surface from damage over time. Staining concrete is a great way to add color and design to any area, but it’s essential to protect it from wear and tear that comes with daily use.

Properly sealing stained concrete helps seal in the color of the stain, prevent fading and chipping, and will help protect against water, oil, and dirt from penetrating into the surface. Cleaning and repairing any damaged areas before applying sealer is essential for preventing further damage because dirt or debris can cause the sealer to chip or peel prematurely. 

When cleaning a stained concrete surface, it is important to use a mild detergent or degreaser designed specifically for this purpose. Using a harsh cleaner could actually strip away the stain or damage its protective layer.

After cleaning, inspect the surface for any cracks, holes, chips or other signs of damage that need to be repaired before sealing. If necessary, fill any cracks using an appropriate filler material like cement patching compound or epoxy filler; then allow it to completely dry before continuing with the job. 

Allow Surface To Dry Completely Before Applying Sealer

Once all damaged areas are repaired on stained concrete surfaces prior to sealing, it is important that you allow adequate time for drying before applying the sealer itself.

Even if you think that the surface looks dry on the outside after washing off debris and dirt with a mild detergent or degreaser product; some water may have penetrated deeper into the pores of your concrete floor’s surface which can take several days even up to a week or more depending on humidity levels in order to evaporate fully. 

It’s also important to make sure that no new moisture has been added since starting your preparations such as rainwater which could delay drying time even further as well as affect adhesion of sealant applied later on down road if not given proper amount of time for complete evaporation beforehand. 

If your stained concrete floor has been exposed recently to heavy traffic (such as construction projects), vehicles travelling over top of them regularly etc., then extra caution must be taken in order ensure complete drying out of all moisture present beneath surface layers prior application of waterproofing.

Preparing and Applying the Sealer to Stained Concrete

Selecting the Right Type of Roller or Sprayer

When it comes to selecting the right type of roller or sprayer for sealing stained concrete, it is important to consider both factors such as surface texture and sealer type.

For a smooth and even application, low-nap rollers such as microfiber rollers are recommended. It is also important to select a roller that can hold enough sealer so that you do not have to constantly dip into the sealer pail. 

When using a sprayer, you must make sure that the nozzle is adjusted correctly to ensure an even coating of the sealer. Unevenly distributed coatings can lead to poor adhesion and staining issues. Additionally, you must select a sprayer with adjustable settings depending on the viscosity of your sealer.

This will help ensure that the sealant is applied evenly over all areas of your concrete surface without leaving behind any gaps or drips. 

Applying a Thin, Even Layer of Sealer

When applying a thin, even layer of sealant over stained concrete surfaces, it is important to take care not to apply too much pressure with your roller or sprayer, as this can lead to uneven coverage or pooling in certain areas. You should also work in small sections when applying the sealant, allowing each section time to dry before moving onto the next portion of your concrete surface.

Additionally, avoid curing (drying) times under direct sunlight as this could cause damage and discoloration due to heat exposure. 

Once you have applied your thin layer of sealant, be sure to inspect your entire worked area for any missed spots or uneven coverage before allowing it time to dry completely.

If there are any problems with coverage during this inspection period, simply reapply more coatings until you are satisfied with the results and allow time for full drying before adding additional layers if necessary.

How Often Should Sealed Stained Concrete be Re-sealed?

Things to Consider When Deciding How Often to Re-Seal

Sealing stained concrete is essential for preserving its appearance, preventing staining and minimizing wear. Sealing can be done either before or after staining, depending on the desired outcome. As a general rule of thumb, it’s recommended that sealed stained concrete should be re-sealed every 1 to 3 years. However, the frequency at which you need to reseal your stained concrete depends on the type of sealer used, the color of stain used, and the environment in which it is located.

When deciding how often to re-seal your sealed stained concrete, you should take into account a few factors: 

• The type of sealer: Different sealers offer various levels of protection; therefore it’s important to understand what kind of protection each sealer offers and if it matches with your needs.

Sealers can range from being highly resistant to stains and other substances or just offering basic protection against fading or discoloration due to UV rays or moisture. Knowing this information will help you determine the appropriate time interval between sealing applications.

• Color of Stain Used: Depending on the color used when staining your sealed concrete, certain colors may require more frequent reapplication than others because they tend to fade faster due to environmental conditions such as UV rays from sunlight or moisture from rain or snow.

Darker colors are also more likely to show dirt and other contaminants quicker than lighter colors – meaning they may need regular maintenance more often than lighter hues in order for them stay looking their best for a longer period of time. Therefore it’s important to understand what kind of color was used when staining so that you can plan accordingly for maintenance intervals accordingly.

• Location: It’s also important to consider the environment in which your sealed stained concrete is located before deciding how frequently re-sealing needs to be done. Locations that are exposed to direct sunlight or extreme weather conditions such as heavy rain or snow may require more frequent re-sealing than areas that are better protected from these elements – like indoors or under coverings/awnings etc… Understanding your surroundings will help ensure proper protection and longevity for your stained concrete surfaces! 

Factors That May Necessitate Re-Sealing Sooner Than Expected

Although sealed stained concrete is generally considered durable enough that it only needs re-sealing every 1-3 years, there are a few factors that may necessitate re-sealing sooner than expected:  

• Heavy foot traffic: Areas with heavy foot traffic such as sidewalks, pathways and driveways tend to experience wear and tear faster than areas with less foot traffic do; therefore these surfaces may need more frequent re-sealing in order maintain their protective properties over time .  

• Exposure To Moisture: Exposure to water (from rain or snow) can cause damage over time by eroding away at sealers over prolonged periods of contact; therefore surfaces in areas where there is an increased amount of moisture should be monitored closely and potentially receive additional applications sooner rather than later .   

 • Accidental Staining: Since stains penetrate deeper into unsealed surfaces compared with sealed ones , any accidental spills should be addressed immediately in order avoid discoloration caused by liquids soaking into unsealed areas . If left untreated , this could eventually necessitate additional resealing further down the line .  

• Changes In Design Aesthetic: As trends change throughout time so too does our aesthetic preferences ; consequently we might find ourselves wanting a different look (color / texture ) for our previously sealed stained concrete surface . In this case , complete stripping away the old coatings would require completely new sealing application regardless of their age .

Do You Have to Seal Stained Concrete?

Do You Have to Seal Stained Concrete

Yes, it is important to seal stained concrete in order to ensure that the color and texture of the concrete remains intact and protected from UV rays, moisture, and other elements. The sealer will also help maintain a uniform appearance over time. Sealing your concrete will also help reduce staining, cracking, or fading of the surface so that it can look its best for years to come.

When selecting a sealer for stained concrete, it is important to choose one with a high solids content that provides maximum protection against water and UV rays. Additionally, make sure you select an appropriate sealant for the particular type of stain or dye used on the concrete.

Is It Better To Stain or Dye Concrete?

When deciding whether to stain or dye your concrete, it’s important to consider how much protection you want for the surface and how long you want the coloration to last. Dyes penetrate deeper into the pores of the concrete and offer better fade-resistance than stains; however, they are not as durable as stains when it comes to water absorption or wear-and-tear.

Stains form a thicker film on top of the surface that offers better protection against some elements but may require more frequent reapplication in order to maintain their colour. 

What Happens If You Don’t Seal Concrete?

If you do not seal your stained concrete, then it will be susceptible to staining from dirt and other substances that become embedded in its porous surface over time. In addition, without sealing your concrete will become vulnerable to cracking due to temperature fluctuations or heavy traffic on its surface.

Furthermore, without sealing your stained concrete it could be prone to fading from UV light exposure as well as becoming discolored from moisture seeping into its core causing mold growth which can further damage the material’s structure.  

What Is The Cheapest Way To Seal Concrete?

The cheapest way to seal your stained concrete is by using an acrylic-based sealant which is usually applied with a roller brush after allowing two days for drying following application of stain/dye treatment onto your substrate material.

Silicone-based sealants are another option but tend to be slightly more expensive but they provide superior protection against staining while still allowing vapour transmission through them which helps maintain breathability within interior spaces where such materials have been used for decorating purposes.


In conclusion, sealing stained concrete is an important step in preserving its quality while adding beauty to any space. A good quality sealer must be chosen depending on the intended use, surface area should be carefully prepared beforehand, and application must be done according to manufacturer’s instructions with attention paid to achieving a consistent layer coverage free of bubbles or lumps.

Finally, re-sealing cycles depend on climatic conditions as well as activity levels in the areas where stains have been applied so regular inspections may be required in order to get maximum protection out of the sealer used. With these tips in mind, you can enjoy beautiful stained surfaces for years to come.
