to two thin coats . Sealers are water-based coatings , that dry and cure through the evaporation of water from the film . Thicker coats tend to hold water longer and will stay soft for longer duration which may lead to tracking . In some cases , being a thick coat , the bottom part of the sealer does not cure properly because of water lock in the system . This will lead to premature failure because the sealer did not bond with the surface -- lack of adhesion . One coat applications deposit approximately only half the required amount , which could lead to premature failure , and wear out quicker than it supposed to be .” McLeod offered the following perspective as to the number of sealcoat applications that will work best : “ The application of pavement sealer is so important in ensuring protection from the elements and extending the service life of the bituminous asphalt concrete . The customer
wants to roll into a beautiful black surface with popping , vibrant directional line stripes enhancing their properties look and value .” McLeod continued : “ It is an industry standard to apply two coats of pavement sealer and most contractors do apply two , however there are factors that determine a one coat versus two coat application . The main decider is the porosity of the surface . For example , if the surface is pitted , old and brittle . a one coat will probably not do the job due to the fact the sealer will lay in the pours sealing the asphalt , however a second coat will lock in the sand in the pores and provide a smoother , longer-lasting service life of the asphalt . One coat applications are typical for residential driveways and non stressed surfaces with minimum exposure to vehicular stresses , such as , bike paths , jogging paths , and school playgrounds .”
Once a sealcoating project is completed , what are reasonable performance expectations ? “ When completed , the customer should enjoy just how the sealcoated area looks black and even ,” Pandrapragada said . “ There should be no peeling , but only minor surface scuffing . The customer may see some tracking in the initial days , which heal with time . Sealcoating might wear out a bit sooner in higher traffic areas such as entrances , exits , etc ., but that should be expected .”
To conclude , the key benefits of sealcoating that customers will appreciate are ... it prevents water intrusion beneath the surface , slows deterioration from oxidation , protects the asphalt binder from oils and gasoline , enhances skid-resistance , enhances flexibility , enables easier pavement cleaning , and ultimately … extends pavement life which should save money .
