Sealcoating: A Quick Guide
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 coating or rather the pavement coating has since time immemorial been marketed as the best thing to do to surfaces since they are protective coating that has always proven in all the cases no matter the weather that they can prolong and extend the duration or rather the time a pavement may take and last after being put up. The pavement coating or the seal coating in most cases may also reduce the friction that is often associated with the aggregates and also associated with the asphalt, it is also advantageous since it helps reduce the antiskid and the friction that is also associated with the asphalt. It is impossible to create all the pavement in the same way, there must be some differences either big or small. 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 can also differ in terms of wear, the refined tar-based sealers often offer the best wear of about 3 to 5 years, the asphalt-based sealer offers a wear period of 1 to three years while the petroleum-based coating lies between the other two sealers. 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 these three are advantageous on their own but are typically selected or rather chosen by the contractor’s preference unless otherwise specified. Before the application of the seal coat the surface must be arid and clean using sweeping or blowing methods. 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 process often require 24 to 48 hours of curing before introducing anything to the surface.
Studies suggest that refined tar sealant are the source of polycyclic aromatic hydrocarbon in streams and creek beds, the same studies suggest that it can be harmful if in any case ingested before curing and ingesting dust that is contaminated by the eroded coal tar sealant.
