PreMark Sealer For Concrete
Ennis-Flint PreMark and PreMark XF preformed thermoplastics must have a primer applied prior to using on concrete.
Preformed thermoplastics will bond just fine with the bitumen oils in asphalt but concrete doesn't have a binder to bond with. If you don't use a sealer with concrete you risk the preformed popping off the concrete.
Choose between a 1-part sealer or 2-part sealer depending on how big the job is and how much sealer you will need.
For all projects where there is plenty of time for cleanup and application, we recommend the 1-part sealer.
For small projects and patch jobs where time is important, the 2-part sealer might make the most sense but does require a special applicator.
