Best concrete sealer

Concrete curbing is a great way to add some curb appeal to your home, but over time it can start to look a bit worse for wear. Because concrete is a porous material, it is susceptible to water absorption, which can lead to the growth of mold, mildew, and efflorescence.

Sealing your curbing will help prevent these issues and keep your curb looking great for a long time. But how do you find the best sealer for concrete curbing that will protect your investment? It’s not as difficult as you might think.

Is It Better To Roll or Spray Concrete Sealer?

Stamped concrete sealers

It is better to roll sealer on concrete curbing rather than spray it. This will help avoid puddling and running of material and will also prevent whitening of the sealer.

Make sure the curb surface is clean and dry before application and that irrigation sprinklers are turned off. If rain is expected, postpone the sealing until later. Add a slip additive to the sealer for added slip resistance.

If a sealer is applied in too thick of a layer or if it is applied in heat, the results can be disastrous and unsightly. It is best to apply the sealer early in the day when the curbing surface is cool.

When To Seal Concrete Curbing?

Sealing your concrete curbing may seem tedious and unnecessary, but it’s actually quite crucial in maintaining the longevity of your curbs. With concrete sealing every two to five years, you can prevent cracks, pitting, and other damage.

Experts recommend waiting until 28 days after the initial pour to seal your curbings, giving the concrete time to cure fully. In reality, most sealers can be applied after this time frame. Applying a sealer is a relatively easy and inexpensive way to keep your curbs in good condition.

How to Choose the Best Sealer for Concrete Curbing?

How to Choose the Best Sealer for Concrete Curbing

As you now know the importance of penetrating sealers for concrete curbing, it’s time to learn how to choose the best one. Here are some factors that you need to consider:

Concrete Porousness

The first thing you need to consider is the porosity of your concrete. If your concrete is highly porous, then you’ll need a sealer that can penetrate deep into the surface. And, if your concrete is not very porous, then you can choose a curbing sealer with a shallower penetration.

To determine the porosity of your concrete, you can conduct a water test. Simply pour some water onto the surface and see how long it takes to soak in. If the water beads up and doesn’t soak in within a few minutes, it’s not very porous.

Surface Texture

One of the most important aspects of choosing a sealer for concrete curbing is to select one that is appropriate for the surface texture of your curbing. The three main surface textures are smooth, troweled, and broomed.

  • Smooth surfaces are easy to clean and maintain, but they can be slippery when wet.
  • Troweled surfaces have a more textured finish that provides extra traction, making them ideal for areas that experience high foot traffic.
  • Broomed surfaces have an even rougher finish that helps to prevent slips and falls.

When selecting a sealer, read the label carefully to ensure that it is compatible with the curbing’s surface texture.

Freeze-Thaw Cycles

Not all sealers are created equal, and some are better suited for areas with high freeze-thaw cycles. When choosing a sealer, it is important to consider the climate in which it will be used.

If the sealer is exposed to frequent freeze-thaw cycles, it is important to select one designed specifically for this purpose. Freeze-thaw cycle ratings are usually listed on product labels, so it is easy to compare different sealers and choose the one that is right for your needs.

Exposure to Sunlight

Exposure to Sunlight

When looking for a sealer for your concrete curbing, you will want to ensure that you get one rated for the sunlight exposure it will get. The amount of sunlight a sealer is exposed to will determine how long it will last and how well it will protect your concrete.

If you are unsure how much sunlight your sealer will be getting, you can always ask the manufacturer or the retailer. They should be able to give you an estimate based on the location of your home and the climate.

Coverage Area

This will ensure that you purchase the right amount of sealer and do not waste any money. To calculate the coverage area, you will need to know the dimensions of the area that you want to seal.

Once you have these measurements, you can use a simple formula to determine the coverage area. The formula is: length x width = coverage area. For example, if you want to seal an area that is 10 feet long and 5 feet wide, the coverage area would be 50 square feet.

Keep in mind that this formula only works for rectangular areas. If your concrete curbing is not rectangular, you need to use a different formula for calculating coverage. If you need to know the coverage area of the sealer, you can also consult the product label.

Application Method

Three common methods for applying concrete sealer are pump-up sprayer, roller, and brush. The best method for applying sealer will depend on the size and shape of the area to be sealed, as well as the type of sealer being used.

Pump-up sprayers are ideal for large areas or sealing concrete with many nooks and crannies. Roller applicators are best for flat surfaces, while brushes can reach tight spaces and corners.

When choosing a sealer, always read the manufacturer’s instructions carefully to ensure that you use the proper application method.

Dry Time

When you are looking to buy a sealer for concrete curbing, it is also important to determine the dry time of the sealer. This is because the wrong sealer can make your curb look glossy and wet, which is not the look you are going for.

If you want to know when a sealer will dry, you need to look at the manufacturer’s instructions. Most sealers will have a specific dry time that they recommend. When in doubt, it’s best to avoid caution and let the sealer dry longer. This will give your curb a perfect finish.

VOCs and Odor

VOCs, volatile organic compounds, are released into the air as the sealer dries and can harm your health if inhaled like an acrylic concrete sealer. The amount of VOCs in a sealer is typically listed on the product label, so check this before making your purchase.

The odor of the sealer is also vital to consider, as some strong fumes can be overwhelming. If you are sensitive to strong smells, look for a sealer with a low odor or allow plenty of time for the sealer to dry before entering the area.

By considering all of these factors, you can be sure to find the best sealer for your concrete curbing needs. A suitable sealer can protect your curb from the elements and extend its lifespan.

How to Seal Curbing With the Best Concrete Sealer?

How to Seal Curbing With the Best Concrete Sealer

After you have chosen the sealer for your unsealed concrete surfaces, it is time to apply it to your curb. You can do this by following these tips:

  • Begin by cleaning the surface of the curb with a pressure washer or garden hose. This will remove any dirt, dust, or debris that could prevent the sealer from adhering properly.
  • Once the surface is clean, allow it to dry completely before beginning the sealing process.
  • To apply the sealer, use a pump-up sprayer, roller, or brush, depending on the type of sealer you are using.
  • Start at one end of the curb and work your way down.
  • Make sure to distribute the sealer across the surface of the curb evenly.
  • Allow the sealer to dry completely before walking or driving on the curb. This usually takes 24-48 hours. Some fast-drying sealers may be dry to the touch in as little as 2 hours.

Following these steps ensures that your curb is appropriately sealed and protected from the elements. A quality sealer will extend the lifespan of your curb and keep it looking its finest for a long time to come.

How Many Coats of Concrete Sealer Should I Use?

The general rule of thumb is two coats for most applications. This will provide adequate protection against stains and wear without making the surface too slippery or difficult to clean, like a concrete paver. Of course, there are exceptions to this rule.

Additional coats may be necessary if the concrete curbing is particularly porous or has been previously sealed with a poor-quality product. In these cases, it is best to apply a thin first coat and then wait 24 hours to see how well it is absorbed.

Additional coats may be needed if the sealer is still absorbed or water beads up on the curbing surface. As always, test a small area before applying the sealant to the entire surface.

Can You Put Too Much Sealer on Concrete Curbing?

When it comes to sealing concrete curbing, more is not always better. Using too much sealer can be counterproductive, leaving a sticky residue that attracts dirt and makes the surface difficult to clean.

It can also make the surface too slippery, which can be dangerous. To determine how much sealer to use, starting with a small area is always advisable. Then, gradually increase the amount until you find the right balance.

Does Power Washing Remove Concrete Sealer?

Yes, power washing can remove sealer from concrete curbing. However, it is important to be careful when using a power washer, as too much pressure can damage the surface of the curb.

If you are planning to power wash your curbing, start with the lowest setting and work your way up until you find the right pressure. Remember to hold the power washer at an angle so that the water does not cause damage to the curb surface.

Can Exterior Concrete Surfaces Be Sealed With a Sealer?

Can Exterior Concrete Surfaces Be Sealed With a Sealer

Yes. Even many experts suggest sealing concrete curbing, as it provides an extra layer of protection. Without this sealant, concrete can absorb moisture, resulting in cracking, spalling, flaking, and discoloration.

Apart from that, the best sealer for concrete curbing will help to prevent staining and fading. Applying a sealer is a simple process, and the results are well worth the effort. Sealing your concrete curbing surface will help to prolong its life and keep it looking its optimum.
