How to prepare the surface before painting for increased duration

A proper surface will allow you to obtain the following benefits when using thermoplastic paint:

  • Easy application
  • Good adherence
  • Better appearance 
  • Long lasting results 
  • Maximum retro reflectivity
  • Optimum performance

Learn more about the process to prepare surfaces and the details that require attention to attain professional results.

Steps for preparing the surface before painting

The following steps will lead to a successful installation:


1.- Stable and smooth surface

Potholes and loose material require maintenance and repairs, for a suitable surface.

2.- Cleaning

The surface must be free from contaminants, such as:

  • Solids: Dust, dirt, or old paint markings.

Liquids: Water, oil, grease, curing agents, or additives.


3.- Moisture

After cleaning, check for nearby water leaks or streams, automated irrigation systems, industrial or residential discharges, puddles, potential rain and/or muggy weather.

The presence of such elements may cause bubbles when the thermoplastic paint is applied, thus affecting application and performance.

4.- Sealant

Next, use an adhesion-promoting additive to ensure proper binding of the paint pavement.

Then, allow to dry for as long as necessary, as per the manufacturer’s instruction, before application.

Best Practices for Each Surface

Below are some tips for preparation, based on the type of surface where the paint will be applied:

Old Asphalt and Concrete

  • Make the necessary repairs, such as potholes, cracks, or pits, so paint can be applied on a stable and smooth surface.
  • If the surface is badly damaged (or with very exposed aggregate) we advise to use a sealant or primer first.

New Concrete

  • Wait a minimum of 30 days after pouring the hydraulic concrete. This will help avoid possible reactions against the moisture in the concrete, which can affect the application of paint.
  • Use a primer or sealant to promote better adhesion to concrete.

New Asphalt 

  • Thoroughly clean the surface, since oil byproducts, such as asphalt, leave many residues behind. This can lead to black spots and may distort the color of the paint.
  • Wait at least 30 days after asphalt installation to prevent mixture bleeding or oozing. This will prevent spots and will give the Paint a perfectly smooth appearance.
