Are you in the middle of a do-it-yourself project involving pavement but don't know how many gallons of paver sealer you need? We've all been there at one point or another. You've scoured the internet for the answer, only to be met with long complex formulas with incredibly difficult calculations. Well, we have good news for you! Calculating paver sealer doesn't have to be an arduous task.

The amount of paver sealer you will need will depend on the size of the area you are covering. As a general rule, 1 gallon of paver sealer is adequate for approximately 150-200 square feet of coverage.

In this blog post, we'll walk you through the process, step by step, to show you how to accurately calculate how much paver sealer you need for your project and help take the guesswork out of it. So pull up a seat, grab your calculator, and let's get started!

Estimating your Sealing Coverage

Before you can calculate the amount of paver sealer you need, you must first determine the area that needs to be sealed. This includes the square footage of the paver surfaces you plan on sealing. Your choice in this step will dictate the amount of sealer required.

When determining how much sealer you need, it’s important to take into account the type and condition of each surface. Sealers are typically sold in terms of coverage per gallon, meaning if a product is labeled “covers 200 sq ft./gal.,” then one gallon should cover approximately 200 square feet under ideal conditions, such as with a smooth, level surface.

However, surfaces that are highly absorbent may require additional sealant; uneven surfaces may require more as well as adding texture and non-slip agents. In addition, seamless versus patterned designs also impact the amount of sealant needed.

Doing multiple coats of sealer will also increase the amount of sealant needed. Debating whether more than one coat is necessary tends to depend on the personal needs and preferences of the home or business owner.

Additional coats can produce a more glossy and vibrant look while extra protection from UV rays, water penetration, and staining could be desired by some homeowners and business owners alike. Ultimately, deciding how many coats to apply depends on several factors and often requires professional advice for best results.

Now that you understand the factors impacting your sealing area coverage estimation, let's move on to measuring the paver surface area in our next section.

Measuring the Paver Surface Area

Measuring the paver surface area is the first step to calculating how many gallons of paver sealer you need. It’s important to be precise here and measure the area accurately so you don’t end up buying too few or too many gallons of sealer.

The most accurate way to measure your paver surface area is to use a measuring wheel. Besides being easy-to-use, a measuring wheel will help you quickly and accurately determine the square footage of the pavers.

To get an accurate measurement, simply roll the wheel back and forth across the entire length of your paver surface area until you’ve covered it all. Record this measurement in square feet, as it will be helpful in determining how many gallons of sealer are needed.

Another option for measuring your paver surface area is to use a tape measure or yardstick. First, measure each side of your paving project individually in feet, then multiply those figures together for a total square footage of your project.

If measuring with a tape measure, make sure to double check each side before multiplying the figures together due to possible discrepancies from the stretch or droop of your tape measure.

Although it can take more time and effort than using a measuring wheel, using a tape measure or yardstick is another reliable method you can use to accurately determine your pavers’ total area.

Once you’ve measured your paver surface area, you can move on to calculating how many gallons of paver sealer you need. That process is discussed in more detail in the next section.

Calculate Gallons Needed

Calculating the exact amount of paver sealer needed for a project can be challenging. There is a simple method that can help determine the correct amount of paver sealer for any size area, however the estimation might not be wholly accurate and you may need to add additional paver sealer if you are working with particularly large areas.

To get a rough estimate of how many gallons of paver sealer you may need for a given area, start by measuring the length and width of your paver surface. It’s important to remember here that you should measure in feet when calculating square footage—not inches—so you may need to convert your measurements.

Once you have your measurements in feet, multiply them together to calculate the square footage of your area. This number will determine how much paver sealer you’ll need.

Next, consider the rate of coverage provided by your particular brand of sealer. Most brands provide coverage information on their packages. Take this number and divide it into the total feet to obtain your total gallons--or part thereof--needed for the job.

You will likely end up with a fractional number from this equation, which you should round up when ordering your materials. Remember, it is better to err on the side of caution and pick up extra sealer than risk running out before finishing the job.

Once you’ve determined how much paver sealer you need, it’s time to move on to actually applying the sealer. In our next section, we’ll discuss best practices for applying paver sealers and how to achieve top-notch results with your project.

Applying the Sealer

Applying the sealer is a fairly simple procedure. It typically involves rolling it out over the surface with a paint roller attached to an extension arm. Depending on the type of sealer and number of layers desired, the application process may involve more than one step.

First, begin by thoroughly cleaning your paver stones with a pressure washer or garden hose to remove dirt and debris. Be sure to allow adequate drying time after before applying any sealer you may need. Make sure that all cracks are properly sealed before you can begin applying the sealer as well.

When you’re ready to apply the sealer, you should wear protective gear such as gloves and goggles, and cover nearby surfaces with tarps or plastic sheeting to protect them from overspray. Pour the sealant directly onto the paver surface and spread with a paint roller or brush.

Use long, even strokes and make sure that it penetrates into all crevices for even coverage. Allow this first layer to completely dry before applying additional coats, if desired.

At this point, there are two basic schools of thought in terms of how many coats of sealant should be applied: some recommend one first initial coat to start followed by multiple thinner coats over time versus applying several thick coats at once for optimal protection against UV rays and weather damage. Ultimately, this decision is up to you based on your preferences and budget.

Once you have completed applying your desired amount of sealer, wait for it to dry completely before tackling any tasks such as walking or driving on your newly-sealed surface.

Now that you know how to apply paver sealer, it's time to discuss matte, glossy and satin finishes that can be created through various levels of sealing. In the next section, we will discuss further detail what each finish does.

Matte, Glossy and Satin Finishes

When it comes to sealing a paver patio, there are three types of finishes to choose from: matte, glossy and satin. All offer different levels of protection, coverage, and shine.

  • Matte Finish: Matte finishes provide natural color enhancement but no gloss or shine. This type of sealer results in a cleaner look with no added sheen and is ideal for pavers that have natural texture or worn boards. It will also give a longer-lasting coating when properly applied and maintained.
  • Glossy Finish: Glossy finishes offer the highest level of protection and coverage because they contain more oil than matte finishes. However, these types of sealers tend to show dirt more easily, so you may have to clean the surface more often than other options. Glossy finishes have a higher amount of reflective qualities which make the colors look more vivid and vibrant. This option is especially good for high traffic areas since it can provide extra protection from wear and tear.
  • Satin Finish: Satin finishes provide a moderate amount of gloss without making the paint too shiny or slick. This type of finish is great for outdoor projects because it reduces the amount of dirt buildup which can cause discoloration over time. It’s also excellent for areas that need slip resistance such as pool decks or staircases since it provides enough traction without being overly glossy.

Each type of finish has its own set of benefits and drawbacks, so be sure to think about what you’re trying to accomplish before deciding on a finish type. That said, all three should be able to effectively protect your pavers if applied correctly.

The next step in calculating how many gallons of paver sealer you need is checking the product label information.

Checking the Product Label

Before purchasing a sealer for your pavers, it is essential to do your research and read the product label. The label will provide information regarding coverage area, coverage rate, application method, and available colors. If you are applying more than one layer of sealer, note that the same brand must be used each time.

The first step should include verifying the coverage area provided on the label. It is important to remember that this number will be based on a single coat at the recommended film thickness.

If you plan to apply multiple coats of sealer, you will need to adjust accordingly. Knowing the exact square footage of your paved outdoor space ahead of time will help in making an accurate purchase.

Next, pay close attention to the coverage rate listed on the product label. This number determines how many gallons per square foot (ft2) you will need for your project. This number may vary based on substrate type, climate or moisture content, or desired results.

It is also important to note that if any additional materials are required beyond what is stated on the label such as additives or colorant, you should consider these items when calculating your total purchase amount.

The application method is also a necessary information to verify before purchasing paver sealer. Depending on the manufacturer, there are different techniques that may be achieved with their specific sealer such as spray application or roller application.

Understanding which application method is involved will help to effectively determine material usage during calculations and proper surface preparation needed prior to application.

Finally, factor in colorant choice when buying sealer for your paver project. Different pigments could affect final coverage but colorants should not affect performance so it’s important to ensure which color combinations work well depending on the desired look you are hoping to achieve with your pavers.

Now that you have reviewed all the necessary information from the product label, it is time to start calculating how many gallons of paver sealer you will need for your project giving uniform distribution and coverage for maximum protection of your hardscaped surfaces.

Uniform Distribution and Coverage

The uniform distribution and coverage of paver sealer is one of the most important factors when considering how much sealer to purchase. All areas receiving sealer must be completely covered, ensuring that no paver stones remain exposed. To ensure complete uniformity, it is important to spray or brush the sealer evenly across the entire area.

When attempting to achieve uniform coverage, some professionals suggest using a "dry spray" application of the sealer, in order to cover an expansive area more quickly. Others argue that using a brush instead yields better results and lasts longer.

A dry spray application may cause uneven coverage and leave some areas susceptible to damage if it rains immediately after application. However, many professionals prefer this method since it allows them to cover expansive areas more efficiently than with a brush or roller.

Whatever technique you choose - whether using a dry spray, brushing, or rolling - be sure that the sealer is evenly distributed over all stones and that there are no gaps or missing sections. This ensures that all areas receive adequate protection from weather elements and wear and tear, assuring an extended life span for your pavers.

Once you have ensured complete uniform coverage and distribution of the sealer, it's time to calculate the total gallons needed for your project.

Calculating the Total Gallons Needed

No two paving projects are exactly alike. Knowing how many gallons of sealer you need for an asphalt or concrete paver project is essential to completing the job successfully and preventing damage to your outdoor space. But, calculating the total number of gallons required can be tricky.

To make sure you purchase enough sealer to finish your project without creating a mess, it’s important to know how much surface area you plan to cover and which type of sealer is best for your project.

One major factor in determining the amount of sealer needed is the coverage rate. Generally, one gallon of sealer will cover between 150 and 200 square feet with 1 coat depending on the paver material and porosity.

This means you can use this ratio to estimate how many gallons you will need by multiplying the total square feet of surface area by two and then dividing that number by 150 or 200 depending on which coverage rate you choose. Doing so will help give an accurate representation of how much paver sealer you need to purchase before beginning your project.

However, due to factors such as varying weather conditions during application, some jobs may require additional seals. It is always better to overestimate how much paver sealer you will need rather than underestimate as there is no way to return excess sealant after it has been purchased.

Therefore, it’s recommended that homeowners add an extra five gallons or so just in case a second coat is necessary for maximum efficiency and protection against the elements.

Fortunately, making the process easier can help ensure that calculating a project's exact requirements for sealing materials does not take too long. In the following section, we'll discuss ways to streamline this task.

Making the Process Easier

In order to make the process of calculating how many gallons of paver sealer needed easier, there are some things that can be done to simplify the process.

The first thing that should be done is properly preparing the area. All weeds and grass should be removed, and any dirt or other debris should be cleaned off so that the sealer will adhere correctly.

If any repairs need to be made to the pavers, they must also be done prior to sealing in order for the sealer to adhere properly. This preparation is necessary no matter what type of sealer is being used.

Another way to make this process easier is to rent or purchase a paint sprayer specifically designed for sealers. A paint sprayer allows much quicker application than brushing and rolling and works with all types of paver sealers. It can save time, labor costs, and material costs.

Finally, it is important to choose a quality sealer with great performance characteristics before starting the calculation process. There are many different types of paver sealers available on the market today, each with their own advantages and disadvantages.

Be sure to select one based on the desired look and longevity for your project, as well as factors such as ease of application and drying time.

Making this process easier is one important step toward completing a successful project, but it is only one piece of the puzzle. After all preparations are complete, you can move on to calculating exactly how many gallons of paver sealer you need.

Now that we have established how best to prepare for and make this process easier, let's move on in our conclusion and overall guide which outlines the final steps in ensuring a successful project completion.


In conclusion, calculating how much paver sealer you need for your project is an essential part of the process. Before you make any decisions, it’s important to carefully measure the area you want to seal, take into account the coverage rate of the product, and calculate how many gallons of paver sealer you will need.

If you’re struggling with the calculations yourself, there are a number of online calculators that can help simplify the process. Additionally, a professional or experienced contractor can provide advice on achieving the best results and approximate the number of gallons needed.

For those who have a good understanding of measurements and do not require assistance from a third party, using mathematical equations is a more accurate approach instead of relying on prediction-based estimations.

It takes a bit more time, but it ensures that you’ll get an exact result which in turn helps ensure cost saving and avoid any potential waste or damage to surrounding areas.

Although it might seem like a daunting task at first, calculating the amount of paver sealer needed for your project is relatively easy when broken down into small steps. Make sure to keep all relevant factors in mind such as weather conditions and material absorption rates while factoring in coverage rates and measuring each area accurately to determine how many gallons you need in total.

With these steps as an overall guide, you’re sure to achieve a successful outcome for your project!

Frequently Asked Questions

Do I need multiple coats of sealer on my pavers?

The answer to whether or not you need multiple coats of sealer on your pavers depends on the condition and quality of your existing paver surface. If your pavers are in good condition, one coat of sealer should be sufficient. However, if your pavers are in poor condition or have recently been masonry-repaired, you may need two coats of sealer.

Additionally, if you live in an area with severe weather conditions that can damage pavers, you may also want to consider applying multiple coats of sealer for additional protection.

What paver size am I sealing?

When it comes to determining the amount of paver sealer you need, the first step is to determine the size of the paver you’re sealing. This is important because different sizes of pavers will require different quantities of sealer—larger pavers will need more sealant than smaller pavers.

To figure out the size of the paver you’re sealing, measure both its length and width in inches. The area of the paver can be calculated by multiplying the length and width together. For example, if your paver measures 10 inches wide by 8 inches long, then its area is 80 square inches.

Knowing this information can help you accurately determine how many gallons of sealer you need for a given project.

What type of sealer do I need for my pavers?

The type of sealer you need for your pavers will depend on several factors, including the types of pavers you have and the climate in your area. If you have clay or concrete pavers, a solvent-based acrylic sealer may be your best option.

This type of sealer should provide long-term protection against UV rays, moisture and other environmental elements. If you experience very cold winters or heavy moisture levels, you may want to opt for a water-based acrylic or epoxy sealer. These types of sealers will give the pavers added protection against weather-related damage.

No matter which type of sealer you choose, it is important to follow the manufacturer's directions for application and maintenance to ensure that your pavers are protected and looking their best for years to come.
