Mastics & Sealants


LAMA offers a wide range of mastic and sealant products that are designed to protect, repair, patch, or fill cracks on roofs and in basement applications. These products are available in both solvent-based and water-based versions, giving customers a range of options to choose from based on their specific needs.


Mastics & Crack-fillers

Mastics offers a reliable solution for repairing, patching or filling cracks on a variety of surfaces, including roofs, flashings, eaves, gutters, walls, chimneys, vents, and more. Our products are designed to be easy to use and effective at addressing a range of issues related to cracks and leaks.



Sealants are essential for protecting surfaces from water, air, and other contaminants that can cause damage. Our asphalt-based sealants create an excellent water-tight bond with substrates, effectively blocking water passages and other harmful substances from infiltrating the surface.
