ZAR® Deck & Siding: Protecting Your Wood Deck

The surface must be clean, dry, and in good condition. Remove all mildew, dirt, dust, loose wood fibers, paint flakes, mill glaze, oil, and grease*. Test the wood for factory treatment by sprinkling a few drops of water on the surface. If the water is readily absorbed into the wood, proceed. If not, do not apply ZAR® Clear Wood Sealer & Natural Toner Base. Wait 1 month and then retest. Repair or replace any loose, cracked or warped boards. All mildew (dark, fuzzy or powdery deposits) must be removed with ZAR® Deck, Fence and Wood Cleaner. Or, use the following solution: one-third cup heavy-duty laundry detergent to 1 quart household bleach to 3 quarts of warm water. Wear protective eye goggles and waterproof gloves when handling the solution. Apply with a scrub brush. Rinse thoroughly and allow it to dry before staining.

For Old Grayed Wood Exposed to UV (sunlight) for More Than 3 Months
Power wash the surface to remove the thin layer of degraded wood and clean surface as above.* Allow the wood to dry thoroughly after power washing before applying ZAR® Clear Wood Sealer & Natural Toner Base.


Apply only when surface and air temperatures are above 50°F and less than 90°F. Do not thin. Stir thoroughly before and during application. Do not apply if rain is expected within 24 hours. Avoid applying in direct sunlight. Apply using a brush, roller, foam pad applicator, or spray. If sprayed, coating should be dry brushed or back rolled for uniform appearance. One coat will protect and beautify the wood while allowing the natural grain to show through. Optional: a second coat may be applied to deepen the color and bring out a soft sheen.

On vertical siding, start at the top on several boards and apply continuously toward the bottom. On horizontal siding, start at one corner on several boards and apply continuously across, breaking at doors, windows and corners. Be sure to maintain a wet edge. Brush out any runs or lap marks.

As a Natural Toner Tint Base
Test the tinted ZAR® Clear Wood Sealer & Natural Toner Base on a sample piece of wood or in an inconspicuous area to determine the final color. When using 2 or more gallons of the same tinted ZAR® Clear Wood Sealer & Natural Toner Base, mix them together to ensure color uniformity.

Areas with harsh exposure to sun, weather or foot traffic will show wear more quickly than other surfaces. If this occurs, clean the affected areas and recoat as necessary.


Dispose of contaminated absorbent, container and unused contents in accordance with local, state and federal regulations.
