Proper maintenance of an asphalt surface requires periodic sealcoating and we’re here to offer sealcoating preparation tips. Kentucky asphalt will deteriorate over time from the effects of weather – especially our freeze and thaw season, rain, sun, chemicals, etc. Sealcoating, like painting the exterior of a house, will protect your driveway or parking area from the elements. It will save you money in the long run.
One of the most important steps in the sealcoating process is surface preparation. In order to obtain a properly sealed driveway or parking area, several steps must be taken to insure proper adhesion of the sealcoating material and to eliminate any sub-surface sources for future deterioration.
First, the area must be swept and cleaned thoroughly to remove all excess debris. Hiring a sweeping contractor is a great way to remove debris and help maintain the sealcoating afterwards. Sometimes it is necessary to wash the surface with water. Grass should be removed from around the edges and from any cracks or potholes that may be present. A weed and grass killer may be applied. It is important that the roots be dead or removed on any vegetation that exists in a crack or hole or it will continue to cause damage to the asphalt in the future. Grease spots should be cleaned, treated and primed.
The next, and one of the most important steps to be taken prior to sealcoating, is the repair of all cracks and holes. The way each is handled will depend entirely on the size and nature of the crack or pothole. Small areas can be remedied by the owner but larger areas should be professionally treated. Your sealcoating professional knows exactly what steps should be taken for each type of area.
Generally the area is properly cleaned, filled and then these areas are sealed. The cleaning involves scraping away any loose asphalt and smoothing the edges of the area. Next a filler product is used.
The actual sealcoating process will be done only when all preparation work is completed. Proper prepping will insure that the sealcoating provides maximum protection. One or more top coats of sealant will be applied depending on the condition of the driveway or parking lot surface.
