Sealcoating 101: Sealed vs. Unsealed Asphalt in Baltimore

Friday, April 11th, 2014

Still on the fence about sealcoating your asphalt? Let’s compare the merits of sealed and unsealed lots.

Weather

It’s now April and getting warm and sunny, but who could forget that winter? Here in Baltimore, it snowed ridiculous amounts and remained cold for weeks. The cold and lingering ice probably did a number on your parking lot. Without sealcoating, the weather erodes the binder in asphalt, resulting in a surface vulnerable to potholes and pitting. The result is unattractive and possibly even damaging to customers’ vehicles as they visit your business.

But not if you’ve recently treated your lot with sealcoating. Even through the last unusually harsh Baltimore winter, sealcoating made certain lots continue to look and feel new. Now that it’s spring, take a look. What’s the difference between a sealed and unsealed lot? The sealed one is clean, uniform and free from potholes and other damage. It doesn’t have patches, which are a band-aid solution resulting in more rough surface.

During the winter, sealcoating offers other advantages. How many times did you pull into a snow-and-ice-filled Baltimore lot this winter, and shuffle carefully into the business, hoping not to slip?

With sealcoating, this is less of a problem. Snow and ice melt more quickly on sealed asphalt than on unsealed asphalt.

Aesthetics

Harsh winter or not, sealcoating simply makes a parking lot look better.

When you visit a business in Baltimore, what’s the first thing you do? In many cases, it’s stepping out of your car into the parking lot.

You probably don’t get down on your knees and inspect the lot, but you do notice—consciously or subconsciously—its condition. This may be the first impression that you have of a business.

An unsealed lot can look worn-out and neglected, possibly reflecting badly on a business owner.

If you’re a Baltimore business owner, you want that crucial first impression to be favorable. A well-maintained parking lot, treated with sealcoating from SealMaster®, will give your customers an impression of professionalism as they take their first steps on your property.

Money

Yes, you have to spend a little money to treat your lot with sealcoating. But you’ll save it in the long run. If you coat your lot every four years, you’ll of course spend more money—in the short term—than the business owner who doesn’t. But after a dozen years or so, he’ll have to re-asphalt his entire lot, a much more costly undertaking. Yours will still stand out as one of the newest in Baltimore, even when it’s years old.

The Verdict

Sealcoating your asphalt carries many advantages—it makes your lot more weatherproof, nicer to look at, and—in the long run—less expensive to maintain. More questions?

Is Thick Sealcoat better?

Friday, September 20th, 2013

PTG Enterprises is a full service commercial asphalt contractor in Baltimore, Maryland. Since 2001, we have set the standard for quality asphalt work in the area, paving thousands of miles of asphalt parking lots. Unlike those other contractors, we care about you and your business. In fact, when you hire PTG, you’ll work with owner Patrick Gillen from start to finish, from the initial site visit and pre-construction meeting to the final walk-through. We are also more than happy to answer any asphalt questions you may have, questions like “Is Thick Sealcoat better?”

Is Thick Sealcoat better

Sealcoat has many benefits: it protects the pavement from the elements and re-beautify the parking lot with a fresh jet-black look. And this is just the beginning. Additional benefits of sealcoating include:

  1. Stain Resistant: Not only can gasoline and oil stain your asphalt parking lot, but they will also soften the pavement. Sealcoat helps prevent this from happening.
  2. Slows Fading: Ultraviolet rays from the sun break the links between carbon bonds within asphalt, both fading and damaging the asphalt. Sealcoat helps shield your asphalt from the damaging rays of the sun.
  3. Ease of Maintenance: Sealcoat makes it much easier to wipe up spills and maintain your asphalt parking lot.
  4. And so much more!

However, none of the above benefits will come to pass if the sealer is not applied properly. So, is think sealcoat better? Quite simply, no!

Bigger is not always better. Sorry Texas. Sometimes, less is more. This is especially when it comes to sealcoat. Sealcoating is not meant to be applied in thick patches and will not provide your parking lot with more protection. It actually has the opposite effect. Thick sealcoat doesn’t cure evenly; is prone to tracking, which can lead to surface cracks; takes longer to cure, which can lead to degradation; and reduces the life of your sealcoating.

How Cold is too Cold for Sealer?

Friday, September 13th, 2013

If you have ever read our blog, you have probably noticed an article or two about the benefits of sealcoating. They are numerous. For starters, freshly laid sealcoat gives your asphalt lot a dark black color while also preventing staining and fading, greatly improving your parking lots aesthetic appeal. But more than that, sealcoating helps slow oxidation and water penetration, thus extending the life of your asphalt parking lot. So when was the last time you had your parking lot sealed? Is there still time? How Cold is too Cold for Sealer?

Sealcoating should only be applied if both ambient temperature and pavement temperature are above 50°F and below 85°F. For these reasons, fall is typically considered the perfect sealcoating season.

How Cold is too Cold for Sealer?

“The best time to sealcoat is from daylight savings time to daylight savings time,” explains Patrick Gillen, owner of Baltimore-based PTG Enterprises, a full service commercial asphalt contractor.

Your window is typically March to early November. However, there are still instances during this stretch of time where conditions are not ideal for sealcoating, when the temperature is either below 50°F or above 85°F. This is why, as we said earlier, fall is the best season for sealcoating. During the fall months, the temperature tends to fall within the proper threshold more often than not.

Fall Sealcoating from PTG Enterprises

Over time, your asphalt parking lot will deteriorate. There is nothing you can do to prevent this from happening. Even the best asphalt pavement will eventually crack and fail. There are, however, several steps you can take, from preventative asphalt maintenance to timely asphalt repair to sealcoating, to ensure that your asphalt parking lot looks great for as long as possible.

So do the right thing for your parking lot and have it sealcoated every 2-7 years, or as needed. Pick up the phone and call PTG Enterprises today. Unlike those other asphalt contractors, we care about you and your business. In fact, when you hire PTG, you’ll work with owner Patrick Gillen from start to finish, from the initial site visit and pre-construction meeting to the final walk-through.

Sealcoating: Protecting Your Asphalt Pavement from Water Infiltration

Wednesday, June 12th, 2013

PTG Enterprises is a full service commercial asphalt contractor in the Baltimore, Maryland area. We have been in the asphalt paving business for more than a decade, paving thousands of miles of asphalt lots during that time. And while asphalt may seem tough and durable, the effects of traffic and the elements take their toll, slowly breaking down the pavement over time. This is why Sealcoating is so important. Contrary to popular belief, sealcoating does a lot more than give your asphalt parking lot add aesthetic appeal.

Protecting Your Asphalt Pavement

Sealcoating: Protecting Your Asphalt Pavement from Water Infiltration

The biggest benefit of sealcoating is its ability to protect your parking lot or other asphalt surface from water infiltration. When water finds its way into the cracks and crevices in the surface of your asphalt, it works its way to the base, slowly eroding your parking lot from beneath. The end results are cracks, pot holes, and, eventually, premature pavement failure.

Sealcoating, which is essentially a thin liquid layer added over a paved surface, is designed to block water infiltration, protecting your asphalt surface and extending its useful life.

Additional Benefits of Sealcoating

  1. Fresh sealcoating has several benefits that will help protect your asphalt. However, there is one benefit of sealcoating that has nothing to do with asphalt longevity: Aesthetics. Simply put, fresh sealcoating will make your asphalt look great, giving it a dark black color. Plus, sealcoating makes your asphalt much easier to clean, allowing you to keep your parking lot looking its best.
  2. Over exposure to oxygen will harden asphalt binders, resulting in brittle pavement prone to cracking. Sealcoating can help.
  3. Sealcoating will help keep small cracks and asphalt degradation from growing and causing premature failure.
  4. Sealcoating will help block harmful UV rays, which can damage your asphalt surface.
  5. Sealcoating will also help protect your asphalt from damaging chemicals, like gasoline and oil.
  6. Sealcoating costs pennies per square foot. Asphalt repairs cost dollars per square foot. Needless to say, it is far less expensive to sealcoat your parking lot every few years than it would be to overlay or completely replace your parking surface.

Parking Lot Maintenance from your Baltimore Asphalt Contractor

Friday, November 9th, 2012

Maintaining your parking lot is not an option. It is a necessity. And if you are worried about money, consider how much money you will save when your well-maintained parking lot lasts 10-15 years longer than an unmaintained lot.

On average, a parking lot which undergoes no regular maintenance will last 10-15 years. A parking lot that is regularly maintained, however, can last 20-25 years. Now ask yourself which scenario makes more sense for you, your business, and your budget.

Asphalt may seem tough and durable, but add up the effects of traffic and the elements, and you’ll see how quickly commercial asphalt can wear down. The trick is to be proactive.

The Importance of Proper Cure Conditions: Baltimore, Maryland Sealcoating

Friday, September 21st, 2012

Sealcoating is a crucial process in the preventative maintenance of any parking surface. However, because sealcoating is water based and cures by releasing all the water from their applied films, cure conditions are in credibly important. Sealcoatings cured under improper conditions are likely to fail prematurely.

Proper Cure Conditions

  1. Temperature: Sealcoating should only be applied if both ambient temperature and pavement temperature are above 50°F and below 85°F. When sealcoating below 50°F, the asphalt particles do not soften to form a continuous film. Because of this, the sealcoating will not only appear grey, but will also lack integrity. When sealcoating above 85°F, the sealcoating will lose its fluidity too rapidly, immobilizing binder particles and preventing them from fusing and forming a continuous film.
  2. Humidity: Humidity directly influences the rate of water loss from the sealcoating film. Sealcoating applied when it is overly humid will take a long time to cure. Sealcoatings will cure much faster at lower humidities.
  3. Wind: Wind can play a very big role in cure times. Under humid conditions, a nice breeze can help sealcoating cure faster. However, under low humidity, wind may cause sealer to cure too fast.

These conditions are the recommendations of the industry and its research association, Pavement Coatings Technology Council (PCTC).

Asphalt Deterioration and its Causes

Friday, August 10th, 2012

Asphalt pavement is the preferred material for most state and federal road projects for a few very good reasons. Most notably, asphalt is known for its durability, strength, resilience, and longevity. Still, even the toughest asphalt road or parking lot undergoes a lot of wear and tear, eventually deteriorating to the point of no return.

Over time the materials that make up asphalt begin to break down, affected by elements such as rain, sunlight and chemicals. Asphalt binder loses its natural resistance to water, allowing liquids to penetrate the surface and deteriorate the pavement.

Asphalt Deterioration and its Causes

  • Cracking: There are numerous different types of cracks, from alligator cracks and edge cracks to longitudinal cracks, block cracks, and more. When it comes to asphalt pavement maintenance and dealing with cracks, you have two basic options: crack sealing and crack filling.
  • Distortion: Caused by improper pavement construction and the deterioration of the underlying base, asphalt distortion includes : channels or ruts, corrugations and shoving, grade depressions, upheaval and utility cut depressions.
  • Disintegration: Asphalt disintegration includes potholes, raveling, and gas and oil spillage.

Asphalt must also be properly maintained and protected to maximize its lifespan.

Sealcoating Performance: Frequently Asked Questions (FAQs)

Friday, June 15th, 2012

I have had the opportunity to respond to many questions pertaining to sealcoatings, based both on refined tar and asphalt, during my many years of lecturing and day to day service to our customers. The following is a condensed list of questions and my answers which are frequently asked.

Q.1. Why are two thin coats of a sealcoating is better than one thick coat?

A.1. Sealcoatings applied in two coats dries and cures much better than one thick coat application. Sealcoatings are commonly water-based coatings, which cure through the process of water release (evaporation). Also, sealcoating film dries from top to bottom, meaning top layers dry faster then from the bottom layers. A thin coat will release water much faster than a thick coat. If the sealcoating is applied in one thick coat instead of the recommended two coats, it will have a tendency to hold water and stay soft for a longer period of time, possibly causing tracking.

Q.2. Why apply two coats, when one coat looks good enough?

A.2. Appearance is only part of the benefits. The sole purpose of sealcoating is to protect and preserve the asphalt. One coat will possibly provide only half of the protection and will wear out in less than half the time. You will have to sealcoat more frequently if you used only one coat.

Q.3. Why did the sealcoating fail or peel?

A.3. Peeling is caused by sealcoating not bonding to oil spots or any other surface contaminants like dirt, grease, etc. or oxidized pavements. Prior to sealcoating application, the pavement surface shall be thoroughly cleaned, oil spots be treated with an oil spot primer. And oxidized surface be primed either with a specialty primer or a thin coat of the sealer or a tack coat.

Peeing and dis-bonding, may also be caused by freezing temperatures during the final cure process, before the film was fully cured. Freezing temperatures will shatter the sealcoating bonds from the bottom layers of the sealer film.
Deposit of tree sap in the pavement profile. The failure is seen as the flaking of the sealer.

Sealcoating over a very hard coating, e.g. Gilsonite-based. The failure appears as chipping because the top coat does not bond and flex with the bottom coat.

Q.4. What causes white streaks in the sealcoating?

A.4. It may be an indication of a problem with the base itself. The limestone from the base may be coming up with water though pre-existing cracks in the pavement. (details in a previous article published here).

If not, then contact your sealer manufacturer to be assured that that the material in question was processed adequately to mix the clay and fillers during the processing.

Q.5. Why does the sealcoating dry gray?

A.5. The graying is caused by sealcoating drying under less than ideal conditions, e.g. shaded areas, cooler temperatures, high humidity, etc. The problem is mostly temporary i.e. after a few days in full sun it will cure to its normal color. Temporary graying can also be eliminated through the use of specialty additive that helps sealcoating dry faster and at a uniform rate. If the problem persists and the sealcoating does dry to its characteristic charcoal black color, the manufacturer should be consulted.

Q.6. Why does the sealcoating wear out faster in traffic lanes, entrances and exits?

A.7. Aside from the obvious reason of more traffic in those areas, it could be an adhesion problem, If the wear is excessive. The surface aggregates in these areas become smooth (polished) over the years of usage. For any coating, including sealcoatings, to bond properly, it is imperative that the surface be sufficiently rough. Our recommendation is to use a specialty primer to prime faster traffic lanes, exits and entrances. These primers penetrate the smooth polished aggregates and allow the sealcoating to bond effectively.

Is Thicker Sealer Better? :: Sealcoating Tips from My Pavement Guy

Friday, April 27th, 2012

The decision to sealcoat an asphalt surface is an easy one. After all, the cost of sealcoating is only pennies a square yard versus repairs and rehabilitation, which can be as much as twenty times higher. What does confuse many business owners and property managers is the amount of sealer needed.

The more the merrier, right? Well, no.

Bigger is not always better. And the same goes for thickness…especially when talking about sealcoating. When it comes to the application of sealer, thicker is definitely not better. Sealer is not meant to be applied in thick patches.

Disadvantages of Thick Sealer

  • Thick coats don’t cure evenly
  • They are prone to tracking and can lead to surface cracks
  • A thicker coat takes longer to cure, which can lead to degradation
  • Thicker coats will reduce the life of your sealcoating

A thick sealcoating will not provide your parking lot with more protection. It actually has the opposite effect. Sealer manufacturers set specific mix designs for their product; when these specifications are not adhered to, the product will not perform as intended.

One of the easiest ways to tell if a parking lot has been over-sealed is if the lot has no texture. An asphalt parking lot should never look smooth, the texture of the below asphalt should be visible.

Avoid the typical more is better thinking —with sealer, thicker is not better!

The asphalt experts here have managed hundreds of pavement projects and have the experience you need.

“There are many different sealcoating options available to property managers and owners today than there were when I started in the Industry,” said PTG Enterprises owner Patrick T. Gillen III. “This works to the advantage of the property and to the pavement. Now, depending on the current condition of the asphalt, I have the ability to recommend several different options depending on the condition of the lot, previous maintenance schedules and budgets.”
