Sealer coat or rather also referred to as the pavement sealer is a liquid mixture that is normally used on asphalt pavements, this is in many cases done after the sealant is properly mixed, and a number of processes are performed on it. The seal coat or the pavement coat is often marketed as protective coating that normally prolongs and extends the life of asphalt pavements. The pavement coat or the seal coat may also reduce the anti-skid or the friction that are associated with the exposed aggregates and in asphalt. It is obviously beyond the human capabilities to create or rather to put up all the pavements in the same way and the same style, there always ought to be a difference be it a big difference or a small difference. The asphalt pavement that is selected is often a poor protector, or rather they offer dismal protection to the surface against harsher environmental climate, environmental chemicals and the environmental hazards that the pavement is exposed to.
Petroleum based sealers unlike most of the other sealers offer protection against water and chemicals somewhere between the two sealers. The coatings may be similar in many cases, but they often differ in terms of their wear, the best tar pavements wear for a period of 3 to 5 years, asphalt-based coating wear for a duration of 1 to 3 years, the petroleum pavement lies between the two periods. The seal coats can be divided into three major categories, this may include the asphalts based pavement, the petroleum-based pavement and the tar based pavement.
All the three types of the seal coating mentioned above are of their various advantages, but they are typically chosen or rather they are typically selected by their respective contractors, this thus makes them distinctly applied because the contractors often have their own different choices and options, this often the case unless otherwise specified. Before the seal coat is applied the surface ought to be dry and clean. Poor adhesion is always resultant to the failure of keeping the surface clean and dry, the process is often done by the use of hand or the pressurized squeezing machine. The equipment should compulsorily have a continuous agitation in order to maintain consistency of the seal coat mix, the process is often a two coat application that requires a range of 24 to 48 hours of curing before anything can be allowed to pass on the surface.
It is a source of hydrocarbons, and can be harmful if ingested before curing.
