Applications & Uses
- Markets
- Applications
- Compatible Substrates & Surfaces
- Basic Uses
PLS is specially formulated for sealing asphalt and portland cement concrete parking lot cracks.
- Preparatory Work
Crack or joint must be properly prepared prior to installation of PLS by means of routing and/or the use of a hot compressed air jet to remove all incompressibles and assure the sidewalls of crack are clean and dry.
- Methods
PLS can only be properly heated in a kettle with both agitation and temperature control. The range of safe heating temperature for the product is between 325-375°F. Material can be pumped or gravity fed into crack/joint. Care should be taken to minimize the amount of sealant left on the pavement surface.
- Mix Design
Blocks of PLS are formulated as a single component system. Do not add to or mix with any other material.
- Application
Install heated sealant directly into cracks/joints not to exceed a 4 inch wide band. Thickness should be controlled to not more than 1/8 inch above pavement surface. Finished sealed cracks and joints will be uniformly level. Refill to achieve a flush to 1/8 inch concave surface appearance. One pound of PLS will fill the following lineal feet:
