Interior or exterior wood surfaces including wood siding, log homes, decks, fences, shake shingles, outdoor wood furniture, all wood types including pressure treated lumber, hardwood, and all other natural wood surfaces.


Surface Preparation: Allow new wood to weather for 3 to 6 months to adequately dry out prior to application. Kiln dried lumber can be stained immediately.

STRIP: Do not use DEFY Ultra Semi-Transparent Wood Stain over painted or varnished surfaces. These surfaces must be stripped prior to application of the product. If sanding is necessary to remove older finishes, use a coarse grit sandpaper. Avoid using fine grit sandpapers as they can adversely affect the penetration of the stain.

CLEAN: All wood surfaces must be clean, porous, and visibly dry before applying DEFY Ultra. Use DEFY Wood Cleaner to remove mill glaze, mildew, graying and other foreign matter that might block surface pores and interfere with product penetration. Rinse thoroughly with a garden hose or power washer (maximum 1200 p.s.i.). DEFY Wood Cleaner will darken redwood and some types of cedar; however, this darkening will disappear once the wood is treated with DEFY Wood Brightener.

BRIGHTEN: While surface is still wet from cleaning, use DEFY Wood Brightener to neutralize the wood, restore the wood to its natural color, and open the pores of the wood, allowing the stain to be more easily absorbed.


WEATHER CONDITIONS: Surface and air temperatures should be between 45°F and 95°F. Avoid application in direct sunlight. Do not apply to wet or water saturated surfaces, or when rain is expected within 4 hours. Stain may be applied to wood surfaces the same day as cleaning and brightening as long as surface is visibly dry before staining.

WATER TEST: After allowing the wood to dry from cleaning and brightening, sprinkle a few drops of water on the wood. It should soak in within a few seconds. If it doesn't, then do not apply the finish. The wood is either not dry enough or not porous enough to accept the finish correctly. Test a small area for color and appearance before starting general application to assure desired results.

MIX WELL: Shake or stir contents before and periodically during use. Do not thin product. To ensure absolute color uniformity from container to container, mix at least one third of the product from a used container with the contents of a new one.

Use plastic, cardboard, and/or drop cloths to protect all adjacent non-targeted surfaces such as siding, windows, masonry, plant life, etc. from overspray and runoff. Immediately remove overspray from non-targeted areas with soap and water. Overspray that is allowed to dry will be difficult to remove; dried product cannot be removed from concrete and masonry.

USE THE RIGHT EQUIPMENT: Hand brushes should be high quality nylon or polyester. A deck brush or paint roller may also be used. If using an airless sprayer, use tips between .011 and .015, and use the lowest pressure that achieves a uniform spray pattern to minimize fogging and overspray. When spraying or rolling, always back brush to ensure a uniform application, and to break the surface tension of the wood so the stain will penetrate deeper, adhere better and last longer.

NUMBER OF COATS & Level of Sheen: If a natural, non-glossy look is desired, apply one coat of stain. If more sheen and a deeper color is desired, apply a 2nd coat before the first coat has dried (usually within 5-10 minutes - watch this video for more info).

DECKS: Start by staining the railings, benches, and undersides of upper-level decks. Once underside is treated, immediately brush out all overspray, drips, etc. Treat horizontal surfaces last.

HORIZONTAL SURFACES: Brush product into surface working out all drips, puddles, or areas of overspray before product dries. Complete entire sections or to a natural break before allowing to dry. Never break in the middle of a board. Thoroughly coat the ends of boards or logs to prevent water penetration. All surface checks on logs should be thoroughly coated. Horizontal surfaces may require maintenance coats more frequently than vertical surfaces as they typically receive more direct sunlight as well as more wear and tear.

VERTICAL SURFACES: Start from the bottom and work up. Treat the entire length of a board before moving up. If necessary, brush or feather in to avoid lap marks. Brush in product before it dries and work out drips, runs, or overspray.

DRY TIME: To touch, 2 to 6 hours depending on temperature and humidity. Allow 24 hours for deck to completely cure before using.

CLEAN-UP: Clean tools and equipment immediately after each use with soap and water.

COVERAGE: One gallon will cover approximately 200 - 300 sq. ft., per coat, depending on wood texture and porosity.
