About Summum Liner
Protecting what matters.
Founded in Quebec, Summum Liner is Canada's reference for high-performance polyurea coatings. Our mission: extend the life of what you own.
Our mission
Built to
last.
At Summum Liner, we believe protecting your assets means respecting them. Since our beginnings in Quebec, we have developed a range of high-performance polyurea coatings designed for the most demanding conditions — northern winters, industrial job sites, high-stress equipment.
Our proprietary XL-7 formula is the result of years of research and real-world application. Every product we formulate, every installer we certify, answers to a single requirement: the protection must last.

Our values
What sets us apart.
Product integrity
We make no compromises. Every XL-7 batch goes through a battery of tests before leaving the workshop. If it doesn't pass our standards, it doesn't reach the client.
Field expertise
Our installers aren't trained online. They complete a hands-on certification program covering application, surface preparation, and quality control. Theory validates practice.
Local roots
Summum Liner is rooted in Quebec. Our suppliers, partners, and workforce are all rooted here. Buying Summum means investing in the local economy.
Full transparency
We document everything: technical sheets, certifications, application limits. Our clients know exactly what they're buying and what to expect after installation.
Continuous innovation
The market evolves, so do our formulas. Our R&D team works continuously on the next generation of coatings — extreme temperature, UV, flame retardant.
After-sales service
The sale doesn't end at delivery. Our network ensures follow-up, touch-ups, and technical support. Because lasting protection requires maintenance.
Our commitment
The Summum promise.
Every Summum Liner application is covered by our performance guarantee. No fine print, no exceptions — if the protection fails, we step in.
Performance guarantee
Every application is guaranteed against material and installation defects.
Installer certification
All our franchisees are trained and certified by Summum Liner. No uncertified applicators in our network.
