What to Consider when Choosing a Concrete Driveway Sealer
A good concrete driveway sealer will stave off stains and discoloration from chemicals and rust and will also minimize the damage that can occur due to freeze-thaw cycles. Concrete is porous, so water can settle in the pores. Then, when ice or snow melts and refreezes, it expands and stresses the surface.
In response, flaking can happen and cracks can eventually appear. Expect to pay from $0.15 to $0.70 per square foot for concrete sealer; cost is determined by coverage per square foot and the concrete’s porosity. Here are some points to consider when selecting a product for a concrete surface.
Types of Asphalt Driveway Sealer
It’s hard to beat the aesthetic appeal of xasphalt (blacktop) driveway, but the material can develop spider web cracks and low spots over time. Left untreated, these issues can lead to larger problems such as potholes. Expect to pay between $0.06 and $0.38 per square foot for asphalt sealers.
There are several types of concrete sealers from which to choose, including coal tar, asphalt-based, plain surface, and fill and seal.
Coal Tar Sealers
These standard sealers have been used on asphalt driveways and streets for decades. True to their name, they’re made from coal tar, a sticky black substance derived from bituminous coal. Coal tar goes on as a syrupy, black liquid and then forms a tough surface on asphalt known as a “sealcoat.” Application is not a DIY project, as it requires industrial equipment that heats the tar to liquefy it.
Coal tar sealers can effectively fill small cracks, seal, and recoat asphalt driveways with a protective coating that lasts up to 4 years. These sealers contain high levels of volatile organic compounds (VOCs), so chemical masks and protective clothing are required during application.
Coal tar sealers are not considered environmentally friendly, and some states and communities have banned their use. A driveway resurfaced with coal tar sealer may emit a tar-like odor for months. Though a coal tar sealer will become very hard and protective, it isn’t flexible once it cures; this means rather than expanding and contracting with changing temperatures, it will likely crack.
Asphalt-Based Sealers
As durable as coal tar sealers, asphalt-based sealers are composed mainly of asphalt cement and emit fewer toxic fumes, making them a popular choice for home use. They are designed to fill cracks and provide a smooth, hard surface that lasts up to 6 years (in typical conditions) before requiring recoating.
Asphalt-based sealers, which contain the same ingredients present in the original asphalt driveway, can be applied by a professional driveway resurfacing crew as well as a knowledgeable DIYer, as there’s no special heating equipment required. Like a coal tar sealer, an asphalt-based sealer creates a hard, durable surface, but it expands and contracts slightly with temperature variations, so it won’t crack as easily.
Plain Surface Sealer
Plain asphalt driveway sealers are usually made of thick black liquid that is generally applied with a heavy-duty paint roller, making it a fairly DIY-friendly project. It’s intended for use on a driveway that’s in relatively good shape, with no potholes or sinkholes. Plain sealers do not contain sand, so they don’t fill holes or cracks, which should be patched or filled (see below) before applying plain sealer.
The product often contains fine silica powder that produces a textured, nonslip surface. Some plain sealers are low-VOC, meaning they create minimal, if any, noxious fumes. A surface sealer offers an added layer of protection that can last up to 3 years.
Fill-and-Seal Products
These sealers contain sand, or sand-like ingredients, that fill cracks up to ⅛-inch wide when spread onto the existing driveway with a utility broom or driveway squeegee. Crack filler products leave behind a textured, nonskid surface. Potholes and cracks wider than ⅛-inch are filled with an asphalt patching product before applying a fill-and-seal product.
Fill-and-seal products for asphalt surfaces are DIY-friendly, and they are often available in low-VOC formulations. A coating can last up to 3 years on average.
Cure and Seal Products
Cure and seal products (for use on concrete) are applied as soon as the newly poured surface is able to bear weight. They help concrete retain moisture and thereby cure more slowly, promoting a harder, more durable surface. The standard method of curing is to wet new concrete thoroughly multiple times a day for a week. When that’s not feasible, a cure and seal product, which protects the driveway for up to 3 years, is a reasonable alternative.
The formula of a cure and seal product is a clear liquid that can be brushed or sprayed over the new concrete’s surface in a thin, even coat. Though fairly DIY-friendly, these products are not designed to prevent concrete from staining or cracking. Their sole purpose is to help the new concrete cure slowly.
Penetrating Sealers
Penetrating sealers—the most common type of concrete sealer—should not be applied before new concrete is completely cured, which is at least 28 days. A single application can last from 5 to 10 years, based on quality, weather conditions, and the manufacturer’s suggestion. Penetrating sealers, which may be solvent-based or water-based (the more eco-friendly choice), soak into the concrete’s top layer and bond with the surface to keep water, stains, and chemicals from penetrating.
Penetrating sealers bond with the particles in the porous concrete surface to prevent stains and keep water from soaking in, which reduces the risk of cracking due to freezing. Depending on the product, a penetrating sealer can be sprayed or poured on and then spread evenly with a squeegee or brush.
Mold Inhibitors
Both mold and mildew can alter the look of a concrete surface: Mold tends to leave darkened stains, while mildew causes powdery, whitish stains. Concrete sealers are available with mold and mildew inhibitors, which is an asset in rainy or humid regions where mold is most likely to develop.
Before applying a concrete sealer that prevents mold or mildew, any existing staining must be removed. This typically involves scrubbing with a brush and a mold-removing product that contains bleach or detergent.
Surface Effects
Specialty penetrating concrete sealers can add various levels of sheen, including satin, semi-gloss, and high gloss. On overdyed concrete, gloss sealers will enhance the color of the concrete while offering an attractive “wet look.” For the best results, apply a surface effect sealer over new concrete that has been cured for 28 days. For existing concrete, clean the surface thoroughly to remove stains and dirt before using a penetrating sealer.
Application Methods
The simplest way to apply most concrete sealers is with a regular garden-type sprayer. A paint roller or a large driveway squeegee are alternative application tools, and sometimes recommended.
When applying a sealer to a concrete driveway, treat the entire surface all at once, without starting and stopping. Should a partial coat of sealer dry and more product be applied later, overlap lines may be visible on the finished surface.
Tips for Using Driveway Sealer
Before trying to apply a driveway sealer, it is important to learn how to clean a driveway and how to apply the sealer correctly. For most sealing applications, make sure that the driveway is in the best condition possible before sealing, including filling in cracks or holes. It’s also important to scrub the driveway before applying any sealers to make sure no materials become trapped underneath. Here are a few tips to consider before applying driveway sealer.
- When cleaning a driveway before applying sealer, it’s best to get the driveway as clean as possible. Scrub with a detergent or stain remover to banish evidence of spills, and follow up with a power washer to deep clean dirt from the surface. For the best results, make any necessary driveway repairs before applying a sealer.
- While applying sealer, note that concrete sealer options can be applied with a pump-type sprayer. If puddling occurs, use a large push broom or squeegee to distribute the liquid evenly. Some asphalt sealers can be spread with a squeegee or rolled on with a heavy-duty paint roller.
