Application Details

DO NOT THIN. Intermix containers to ensure color uniformity. Stir thoroughly and often during use. Apply to a small area and allow stain to dry to ensure acceptable appearance and penetration. Apply one thin coat with a high quality brush, paint/stain pad or with spray equipment. When applying by roller or spray, always back-brush for best results. To help avoid lap marks, apply to only a few boards at a time, and maintain a wet edge.

Apply when no precipitation is expected for 24 hours, and when air and surface temperatures are 50°F (10°C) to 90°F (32°C) and will remain above 50°F (10°C) for the next 24 hours. Avoid staining in direct sunlight or on hot surfaces.

Drying Time

Normally dries in 24 hours when applied in optimal temperatures of 50°F (10°C) to 85°F (29°C). Application in high humidity or in temperatures below 50°F (10°C) may prolong drying times. Allow 24 to 48 hours of drying time before light foot traffic or replacing furniture.


Approximately 250 to 350 sq. ft. (23.2 to 32.5 sq. meters) per gallon (3.78 Liters) depending on application, wood texture and porosity.
