When you notice your drives are fading, you should make sure you apply sealants. The seal coating procedure will help restore the color of driveways. The drying and fading of blacktop is accompanied by hardening of paving material. With time, when you have laid down your driveways, they will begin to harden on the outermost layer. The blacktop is made up of binders, which harden due to constant exposure to ultraviolet rays.

The baking by sunlight will render the surfaces inflexible meaning they are not able to expand or contract as desired. A hardened driveway blacktop will start showing cracks. When you use sealcoats, they improve the flexibility of your blacktop. It is able to expand when it is heated by sun radiation and contract in times of cold weather.

When you use a sealant product, you restore the beautiful black color of pavements. You also improve the flexibility of driveways and they can expand as well as constrict due to changes in temperature. To prevent cracking, asphalt pavements should be able to expand when they are exposed to heat and constrict when it is cold.

Sealcoating is simply a driveway or parking lot restoration procedure. It will help enhance the visco-elasticity of blacktop thus minimizing the cracks. When the first coating is applied about 6 to 12 months after the installation of pavements, other successive coats should follow. It is recommended that you sealcoat parking lots and drives after about every 2 to 5 years.

Apart from environmental factors, asphaltic material suffers from manmade factors such as gasoline products and salts. Gasoline products like transmission fluids and oils will spill on surfaces of pavements and cause the binders to deteriorate. If not checked, the areas, which receive constant spills such as the parking lots, could deteriorate fast.

Your blacktop is likely to collapse as the material fills the empty cracks. By using sealants, it helps protect water from penetrating inside pavements. The sealants provide a membrane cover, which is weatherproof. With timely application of sealcoats, it will extend the time life of your asphaltic pavements. Before you apply any sealant product, ensure the surfaces are in good condition.

It is therefore, important to repairs the cracks, potholes, and other forms of defects before you apply sealants. The contractors you choose to sealcoat driveways, they should be qualified, and use the right products. There are many coating products in the market and if you do not use quality sealants, you may spend a lot of money.

With regular inspection, you are able to know the right time to coat pavements using sealants. Sealcoats will also prevent water from infiltrating the sub base and loosening the material underneath blacktop surface. Water is an element that is as destructive as the UV light. The water entering the sub grade layer is likely to freeze inside and expand. Freezing water will widen cracks as it expands and when it melts, it leaves behind spaces that make the blacktop to crumble.
