Why Seal Coat ??

Here's how a 6 month old driveway looks before the WhySeal treatment.

Can you tell the difference?

Seal coating is very important in maintaining structurally sound pavements for the following reasons:

Asphalt is made up of fine sand particles and larger stones held together by liquid asphalt cement. The cement evaporates from exposure to the sun and wears off from salt and water exposure, turning the asphalt gray. This gray color is the color of stone and sand with no tar holding them in place. It is an indication of oxidization, and less flexability in the asphalt. Asphalt common name is flexible pavement, unlike cement, asphalt is designed to flex when the frost heaves the ground. Less flexability means a larger likelyhood of cracking during frost heaving.
Our sealer is made by the same people who make 90% of all the liquid asphalt in Ontario. Liquid asphalt is what all the asphalt plants use to make asphalt. By applying Whyseal sealer yearly, you stop this process and keep your asphalt surface like new indefinitely . .
Structurally sound pavements can dry out prematurely from the sun’s ultraviolet rays. It makes the asphalt cement brittle and as a result the asphalt fines and then the larger aggregate can ravel away. The sealer forms a tough bond that does not allow the UV rays from the sun to penetrate into the pavement.
Once the pavement has been weakened from the above two conditions, water can wash away the aggregates that are the strength of any pavement.
Asphalt is not a waterproof substance. If water is left sitting on the pavement it can penetrate into the sub-base causing premature pavement failure during freezing and thawing. Our sealer reduces these affects by making the pavement much more waterproof and the jet black color raises the temperature of the pavement making water evaporate more quickly and makes ice melt more quickly in the winter.

Blacktop Asphalt Seal Coating Seal coating protects your pavement while providing a jet black finish that keeps it looking great.

Our 1 year sealer is a composite oil/tar sealer that is oil based just like your asphalt. It bonds to the surface and never tracks. Your asphalt is protected so that when it heaves in winter, it does not crack.

Procedure In order for seal coating to do its job, any structural failures or wide cracks over 10 mm must be repaired in advance (see our "Asphalt Patching and Crack Sealing Services" information - click here). Next we can seal coat your pavement with a thick coat of BlackMac asphalt sealer, a composite asphalt based sealer high in polymers. The sealer is applied in the following manner. First we sweep the pavement surface free of any heavy dirt areas, and then blow off all the dirt, dust and debris with heavy duty air blowers. All bad petroleum stains are burned off to allow the sealer to adhere in these areas. Next, the sealer is spray applied onto the pavement for uniform coverage. We can coat from 6, 000 – 10,000 square meters in a single day, depending upon location and access.

Cost Of Sealing your Driveway or Parking Lot

Our regular sealer lasts for up to 2 years and most driveways are $50 to $100 dollars - cheaper than buying all the things to do it yourself! Our price is 12 cents per square foot, so you can calculate the cost yourself with a quick measurement. Also beware of cheap prices - you get what you pay for in this business! I could charge 8 cents - but you would get an 8 cent job! If you want it done right, you should be paying someone 11 to 15 cents per square foot! Also, there are lots of guys in rusty old pickups with no name on them and no insurance! If a hose bursts and your house is covered with sealer, the bill could be in the thousands with the fly-by-niter long gone. Don't forget when comparing prices - about our great warranty! We are not the cheapest, but we are the best value for your money!

........here is what a leading home expert has to say about when and why to seal. http://www.askthebuilder.com/074_Blacktop_Sealers_-_The_Right_Stuff.shtml

DEAR TIM: I'm a do-it-yourselfer and would like your opinion. My blacktop driveway is 3 years old and has never been sealed. It still appears black in color. My boyfriend tells me that I can wait another few years before sealing it. I have also heard that gasoline and oil can hurt blacktop. Is this true? If so, can you recommend a treatment to prevent this damage? How often should I seal my driveway?
DEAR C. O.: Hurry! Get to the local building supply store as fast as you can. You have already waited too long! Your driveway should have been sealed at some point within its first year depending upon your geographic location. Blacktop or asphalt paving is a very interesting surfacing material. The asphalt industry actually markets the material as a flexible pavement. This claim arises from the fact that the asphalt cement, the material that holds together the small pieces of stone and sand in the blacktop, can remain pliable for a long period of time. This quality helps the asphalt or blacktop to resist cracks if installed properly. However, asphalt which is exposed to air and sunlight will begin to loose this flexibility. The asphalt actually begins to oxidize. Ultraviolet light (UV) from the sun also helps to breakdown the asphalt cement. This is where problems begin to happen. If the asphalt oxidizes, it becomes brittle. The bond between it and the sand and stone particles(aggregate) begins to fail. The result of this process is cracking and loosening of individuals pieces of aggregate. If you live in a climate that experiences cold weather, this process is accelerated by water which enters these cracks and then freezes.

Note from Whyseal: Coal Tar and Acrylic sealers destroy asphalt. I have sealed thousands of driveways and often hear the comment "sealing wrecks asphalt". This is true with acrylic and coal tar sealers. Acrylic is NOT pliable. It is rock hard with no give. When the asphalt expands or contracts, the acrylic which has "bonded" itself to the surface, does not move. The result, is cracking of the surface. The same is similarly true with coal tar. It expands and contracts at a different rate than the asphalt. Several layers of these sealers cause cracks large enough that they traverse all the way through the inch and a half asphalt of your driveway. You may ask - well why do they sell it if it's bad for asphalt? Why do they sell alcohol or tobacco? Because we want them and they are relatively cheap. That's what we want so they continue to sell it. The product I use is flammable and vapour harmful - insurnace wouldn't let them sell it in stores, but it is the ONLY thing 100% compatible with asphalt!!Click here for pictures and proof!
