Asphalt is a complex paving material that uses many chemicals and petroleum-based products. The composition of asphalt makes it hard for paint to cling to it. Whether you’re striping a parking lot or putting in a three-point arch for your driveway basketball court, there are specific paints that work better on asphalt. Knowing the types of paint to use on asphalt will prevent you from wasting your time. The right paint will adhere to the asphalt, look bright and vibrant, and last a long time. Don’t choose the wrong paint that will peel up after a single rainfall.
Coal tar paint isn’t as expensive as acrylic paint, but it is more dangerous and caustic to work with. It is mixed with other polymers to make it tougher and more durable than the other types of paint. It can handle a high traffic area and unrelenting UV rays from the sun. Coal tar paint is a black sealant that’s commonly used as paint coverage for large areas.
Acrylic paint is the go-to for most asphalt professionals. It is water-soluble and polymer-based to prevent the lines from lifting off the asphalt. Since it is water-based, it won’t cause damage to the asphalt, subgrade, or surrounding areas. Acrylics are available in many different colors and can be applied with brushes, rollers, or spraying equipment. As the most popular and versatile kind of paint, acrylics are more expensive than other paints.
Oil-based paint is like acrylic paint in that it comes in many different colors and can be applied with various tools. The physical properties of oil-based paint are the same as acrylic, except it’s not made with water. This kind of paint is slow to dry but will withstand high-traffic areas for a long time. Oil paint isn’t flexible, so it will eventually crack, break apart, and need replacement.
Water-based latex paint comes in many colors too. It can be specially formulated for use on asphalt. The asphalt formulation has already been sealed with another kind of paint, usually coal tar paint. It is the fastest drying type of paint to use on asphalt and is dry to the touch within three hours.
