Concrete and Asphalt Driveways
Both concrete and asphalt are made from gravel or sand and stone. The difference between these two materials lies in how these ingredients are bonded together. The adhesive in asphalt is a petroleum-based substance called bitumen, whereas cement is the binding agent in concrete. When these materials dry they provide a hard-wearing surface which is used in the building of roads and driveways. Whether you have a concrete driveway or an asphalt driveway they will both benefit from a sealer.
But what is a driveway sealer and why is it necessary to seal your driveway?
What Is a Driveway Sealer and Why do I need it?
Whether your driveway is concrete or asphalt, sealing your driveway is essential for prolonging its life by protecting it from the UV rays, chemicals, and oil stains, as well as the freezing and thawing during winter months. The UV rays of the sun can cause major damage over time as concrete and asphalt are not naturally UV resistant. However, there are plenty of UV stabilized sealers on the market that will protect your driveway for years to come.
Sealing your driveway also makes it far easier to clean which is great for maintaining curb appeal. Preventative maintenance is cheaper in the long run as it can save you from having to do expensive repairs or having to resurface the entire driveway. A driveway sealer does what the name suggests, it seals off the surface from the elements but there are also specialty sealers available.
Types of Driveway Sealers
An expertly built driveway can hold its own against the elements, but over time they can start to degrade. Web-like cracks can form as well as low spots and if neglected these can lead to potholes which can end up costing you money in the long run. Driveways can also be susceptible to mold, especially in humid regions. This is why selecting the correct driveway sealer for your specific needs is imperative. Here is a brief list of the different types of driveway sealers:
- Coal tar sealers
- Asphalt sealers
- Acrylic sealers
- Oil-based sealers
- Fill-and-seal sealers
- Mold inhibiting sealers
- Expoxy sealers
- Linseed oil-based sealers
Coal Tar Sealers
Coal tar is a coal derivative that is a black and syrup-like liquid that is easy to apply. It is very effective in filling existing cracks and the coating can last a long time. It stands up well to oil and gasoline stains and resists fading due to sun exposure.
The downfall of coal tar sealers is that it is not ideal for DIY application and is toxic to the environment. Instead of expanding and contracting it is likely to crack in extreme weather as it is not very flexible. It also contains toxic chemicals and because of this has been banned in certain states and cities.
True to its name asphalt sealer contains a lot of the same materials as asphalt itself. Like coal tar sealers asphalt sealers are easy to apply and last a long time. It can be more expensive than a coal tar sealer but is far more eco-friendly. Once cured asphalt sealer has some flexibility so it will crack as easily as coal tar sealers.
Asphalt sealers penetrate deep into the existing asphalt and best of all it is DIY friendly as no heating equipment is needed for application as is the case with coal tar sealers.
Acrylic sealers are environmentally friendly and come in an array of colors and finishes. It is an ideal driveway sealer but it can be expensive. Most acrylic sealers are UV stabilized and hold up well to temperature fluctuations and harsh environments. Even though it is expensive they last a long time which will save you money in the long run.
Unlike Acrylic sealers, oil-based sealers penetrate the surface of the asphalt and last a lot longer before having to reapply. However, oil-based sealers are not environmentally friendly. These sealers do not protect the asphalt from UV rays and are less effective in resisting oil and petroleum stains.
These types of asphalt sealers contain sand or silica particles that fill in small existing cracks and seal the asphalt at the same type. Fill-and-seal type sealers are ideal for cracked asphalt but they will not work on large cracks or potholes. This sort of damage needs to be patched before moving onto sealing.
Mold Inhibiting Sealers
Mold, mildew, lichen, moss, and algae can ruin the look of your asphalt or concrete driveway. Mold inhibiting sealers are best for warm, humid climates where fungi and algae thrive. If your driveway is prone to mold or algae, it is best to remove all the mold or algae and clean your driveway thoroughly before applying a mold inhibiting sealer.
Epoxy sealers are very hard to wear and much more durable than acrylic sealers. Epoxy sealers are easy to clean but do not penetrate the surface like asphalt sealers. Like acrylic sealer different colors are available.
Epoxy sealers usually cost more than acrylic sealers, the finish can be slippery and they are not as breathable as acrylic sealers.
Linseed Oil-Based Sealers
This is an early method of sealing asphalt driveways and it is a great alternative to other driveway sealers that may have negative effects on the environment. This option can be quite effective in preserving the asphalt and concrete driveways. Linseed oil-based driveway sealer is one of the safest options as there are no harmful fumes and is easy to mix up yourself.
Why Is it Important to Use a Breathable Driveway Sealer for Concrete?
A vapor permeable or breathable driveway sealer may seem counterintuitive. However, when it comes to concrete driveway sealers, vapor permeability is a must. A breathable concrete sealer may slow down the movement of water and vapor through the surface of the concrete but should not stop it completely.
Over time, a non-breathable concrete sealer could cause delamination as well as the degradation of the concrete itself. It is not only rain you have to consider but the water content of the earth below your driveway sealer which is in constant flux, even if you live in a dry area. Most concrete driveway sealers available are breathable, so do not be concerned if the water seems to absorb slowly into the surface of your sealed driveway, as it is not only normal but ideal.

How to Seal Your Driveway, a Step-by-Step Guide
Before we get right to applying the driveway sealer preparation is key. If your driveway is in very bad condition you need to look at patching up potholes and filling in large cracks before you move on to sealing.
Allow crack filler and patched areas to fully cure before moving on to sealing your driveway. If your driveway is in fair condition you can proceed with the steps below. What follows is a general guideline that will be a great supplement to the instructions that came with the driveway sealer that you have selected.
What do You Need to Seal Your Driveway?
The great thing about sealing your driveway is that it is DIY friendly as it requires no special expertise or heavy machinery. With a few household items and some sealer, you will be well on your way to sealing your driveway.
- Garden hose and water supply
- Stiff-bristles brush or broom
- Long-handled brush, roller, or squeegee (Depends on the type of sealer)
- Painters tape
- Plastic sheeting
- Rubber boots or old shoes
- Gloves and old clothes
- Driveway sealer
- Leaf blower (Optional)
- Power washer (Optional)
- Weedwhacker (Optional)
- Drill and paint mixing attachment (Optional)
Step One: Planning
Check the weather forecast to make sure it is an ideal time to seal your driveway. The ideal temperature for sealing your drive is above 10 °F. Avoid attempting to seal your driveway on extremely hot days as the sealer could start drying before you are finished applying the first coat of sealer. Not to mention working in the heat can be extremely uncomfortable.
The sealer will need at least 48 hours to cure properly so make sure there is no rain forecast for the following few days.
Step Two: Remove Debris
Begin by removing all debris from the surface of the driveway. This includes overhanging grass as well as weeds that may have sprouted inside small cracks. You may have to do this using your hands unless you have a weed whacker handy. Use a leaf blower or a broom to get rid of the bits of grass and weeds.
Step Three: Power Wash
Pressure washing is a great way to remove stubborn bits of debris and dirt. Alternatively, you can use a garden hose and a stiff-bristled brush. You may also need to use a detergent or degreaser if you have any oil spots or grease stains. Dirt and moisture will prevent the sealer from bonding to your driveway. Once thoroughly washed, rinse thoroughly and allow the driveway to dry before moving onto the next step.
Step Four: Mask and Mix
Use painter’s tape to mask off any areas that you do not want to get sealer onto, for example where the driveway meets the wall or garage floor. Lay plastic sheeting on the area where you wish to mix the sealer to protect from spills as even spills on your driveway can show through after sealing. Mix the sealer using a paddle. Be sure to mix the sealer thoroughly. A paint mixing attachment for a drill will be a lot easier and save you some time.
Step Six: Cutting In
Cutting in is a phrase used for painting the corners and edges first before moving onto the larger areas. Use your paintbrush or small roller to apply the sealer to these areas. Make sure to not apply too thinly. The aim is to saturate the pores of the driveway.
After you have cut in the cover and edges of your driveway it is time to move onto the rest of the driveway.
Step Seven: Pour and Spread the Sealer
Plan to start from one end of the driveway working your way across to completion. If you are a thin sealer on concrete you may want to use a tray and roller for the job. If you are using a thick asphalt sealer, a squeegee or a push broom may be better suited. Always refer to the driveway sealer manufacturer’s instructions before proceeding with sealing your driveway.
Pour the sealer in a line across one end of the driveway and use the squeegee or broom to work the sealer into the asphalt while spreading it around. Proceed to move backward as you work until you reach the other side of the driveway. If you are using a roller, roll the sealer from your tray onto the driveway, working the sealer into the driveway while spreading it around.
Step Eight: Finishing it Off
Once you have coated your drive completely in the driveway sealer, place the sealer pails at the entrance of the driveway to prevent people from driving onto it before it has cured. You will want to keep people from walking on the surface, a little construction tape around the perimeter should do the trick. You may need to apply another coat the following day.
It is best to wait at least 48 hours before you use the driveway as normal.
Our Tips and Tricks to Help You Seal Your Driveway Successfully
If this is your first time sealing your driveway on your own, you may need some extra tips and tricks to make the process as smooth as possible. Here are some of our tried and tested tips to make it easy for you to seal and protect your driveway.
- If you are looking for a natural look, it is best to select a driveway sealer with no-gloss or matte look. Matte finishes are ideal as they tend to be less slippery.
- If you are mixing the sealer with a drill and paint mixing attachment, cut a small hole in the top of the pail of the sealer just big enough to allow the attachment through. Mixing this way can prevent accidental spills.
- When sealing your driveway wear shoes and clothes that you do not completely mind ruining. Sealer is bound to get on your clothes as well as on your shoes and it can be near impossible to clean or remove.
- If you are having difficulty removing weeds from in-between cracks in your driveway, try mixing up a solution of borax, white vinegar, and dish soap and spraying it onto the weeds. The following day the weeds should have died and will be a lot easier to pull out.
- The best time to seal your driveway is in the morning after the dew has evaporated. This will allow the driveway sealer the rest of the day to cure and it is a great way to avoid working in the heat of the day.
- If your asphalt driveway is newly built, you should wait about 6 months before you apply a sealer to your driveway. This will give it enough time to cure.
- Applying multiple coats will ensure maximum coverage as well as an even finish. This is subject to the consistency of your driveway sealer as well as the manufacturer’s instructions.
- Remember not to walk on the driveway for at least 8 hours after applying your sealer. Motor vehicles should be kept off the driveway for at least 24 hours.
It is easier than you think to seal your driveway yourself. With our recommendations, you now have the tools to choose the best sealer for your driveway, whether it is concrete or asphalt. You will also know all the best tips and tricks to make sealing your own driveway easier than ever!
