INSTALLATION PROCESS
Great Northern doors should be installed only by professional garage door installers
FINISHING
You may choose to have your door professionally finished by Great Northern Door
or coordinate finishing yourself, once you receive your door. Doors that are delivered
without stain will be shipped to you, sanded 120 grit and ready for finish. Due
to transportation and handling, additional sanding may be required before applying
stain or paint.
The door must be finished on all surfaces and edges within ten days of delivery.
Doors must be stained with a Sikkens Cetol 1 & 23 Plus stain or painted with a Sherwin
Williams Alyd Primer and then a Sherwin Williams Latex paint.
MAINTENANCE
We recommend annually checking the door’s finish to verify that it is preventing
moisture from reaching the wood’s surface. Refinish doors every one to three years
as necessary, or as recommended by the finish manufacturer. We want your garage
doors to have a long and useful life.
