FINISH WITH CONFIDENCE

Exterior finishing is where
callbacks get expensive

Powered by FibreGrit® Technology

Built for serious durability

DuroGrit is powered by patented FibreGrit® Technology and designed for strong mechanical and UV resistance. This is the core reason it belongs in exterior applications where pros need more than a finish that looks good on day one.

DuroGrit is a 1-coat exterior wood stain and finish

A simpler exterior finishing process

Applies in 1-coat

Traditional exterior systems often require multiple coats, adding time and labor to every job. DuroGrit simplifies that process with a one-coat, no-wipe-off step so crews can move faster with less effort, without the usual back-and-forth of multi-coat schedules.

One finish, more applications

Formulated for the jobs you do

DuroGrit can be used on new and old wood across a range of exterior applications, including siding, decks, outdoor furniture, and other exterior wood surfaces. That gives pros one finish they can evaluate once and use across more of the work they already do, without juggling multiple product lines for similar jobs.

  • Fencing / structures

Less risk after the job

A finish you’re proud to sell

When an exterior finish fails, it reflects on you. Clients want a solution that holds up, not another product that looks good for a few months and then disappoints. DuroGrit gives you a durable exterior finish you can recommend with confidence, especially when homeowners ask tough questions about long-term performance.
