PK has the equipment and experience to install all types of permanent pavement markings both non durable (lasting 1 year or less) and durable (lasting 3 years or more). In selecting which type of material to use, an owner/agency must consider a number of factors such as: pavement type and condition, the desired frequency of restriping, the dangers of restriping, the level of desired reflectivity and the safety gained by wet reflectivity. These factors must be weighed against the cost of providing the longest lasting, most highly reflective marking that can be seen day and night when it’s dry or raining.


Plural component materials are applied using specialized application equipment that mixes two separate compounds during application to produce a durable marking with superior color retention and reflectivity. They can be applied at temperatures down to 40 degrees between April 1 and November 15. Depending on the choice of optics used, plural components can reach reflectivity levels that can exceed 1000 milicandelas (standard paint is approximately 250 mcdl). They require careful surface preparation to ensure maximum bonding to the road surface.

Polyurea is the highest grade of the plural component material used in Michigan. It has the best color retention, is the most durable with a service life that can exceed five years.

Modified Urethane is another plural component material used in Michigan. As with polyurea, it is a durable marking. While its durability and color retention may be slightly less than polyurea it is a superior material compared to non durables and will last 3-5 years.

Methyl Methacrylate (MMA) is a durable pavement marking material recently introduced to Michigan in 2012. MMA originated in Europe and has been widely used throughout the West and Northwest United States. It can be applied to any surface or recessed for longer life. It’s splatter design creates peaks and valleys within the line surface that allows rain to flow off of the line creating wet reflectivity.
