Technical Specifications

Professional Contractor:
On Horizontal or Vertical Surfaces: Apply solution with a
pump sprayer (no aluminum parts) or airless sprayer.
Safe Handling directions detailed on other side must be
followed to avoid exposure to over-spray.
Application Instructions
Before You Start – Replace rotted, extremely weathered or
warped boards. Pre-rinse grass, plants and shrubs
surrounding wood structure to be stripped, then cover to protect
foliage from product exposure. Mask off siding and cover all
wood surfaces not intended to be stripped. Cover any exposed
aluminum surfaces (siding and flashing) to prevent corrosion.
Protect adjacent concrete surfaces from rinse
water. Sweep away surface dirt and debris. If the surface is in
direct sunlight and hot to the touch, dampen with fresh water to
cool. Remove any standing water before beginning application.
Weather Conditions –
For best results, apply when outside temperature is above 50 ° F
(10 ° C), and when 24 hours of precipitation-free weather is
expected. Surface to be stripped should be out of direct sunlight
to avoid premature evaporation of the product.
Application Steps –
Step 1 – Prepare to Use
Moderately shake container for 15 seconds, then pour into
sprayer tank. If using a brush or mop, pour product into a 2-
1/2 gallon or similar sized plastic bucket. Do not mix with any
other products.
Step 2 – Apply
Working end-to-end on 5-10 boards (20 sq. ft.) at a time to
maintain optimum surface wetness, apply product and let sit
for 15 minutes. If stripper dries prematurely, keep it wet with
additional product as needed.
Step 3 – Pressure Wash
Using a 40 ° tip and 1,500-2,500 PSI for pressure-treated
wood and hardwood, 500-1,000 PSI for Cedar and
Redwood, pressure-wash the surface to rinse away
dissolved coating. Move lengthwise with boards to
avoid cut marks across grain.
OR
Step 3 – Brush and Hose Rinse
If pressure washing cannot be employed, vigorousy scrub
surface with a Wolman WOODWORX
®
Deck Brush or other
stiff, synthetic, short-bristle broom or brush for several minutes
using moderate pressure, then rinse thoroughly with a
garden hose, using the highest pressure nozzle setting
available.
On a vertical surface, continually rinse stripped areas to avoid
streaking. Rinse any wood fibers off surrounding surfaces
immediately. When dry, surface should appear clean, bright
and free of previous coating.
Repeat Steps 2-3 on each 5-10 board section (20 sq. ft.) until
entire surface has been stripped. When finished, rinse
surrounding grass and plants thoroughly.
Special Note: After stripping Cedar, Redwood or exotic
hardwoods, black tannin stains may rise to the surface
and give wood an overall darkened appearance. If this
occurs, treat affected areas with Wolman Deck & Fence
Brightener liquid concentrate to restore the natural wood
color. DeckStrip is not designed to remove tannin stains.
Recommended Number of Coats – APPLY ONE (1)
COAT, and allow to sit for ENTIRE recommended time of 15
minutes. Stubborn spots or surfaces with built-up, multiple
coating layers may require a second application.
CAUTION: BARE WOOD OR COATED SURFACES CAN
BECOME SLIPPERY WHEN WET. Use caution when
walking on wet surfaces.
Coverage Rate – Depending on coating type, number of
layers, surface porosity and method of application, one (1)
gallon covers approximately 150 sq. ft.
Dry Time – Allow wood to dry thoroughly before re-applying a
water-base finish, and at least 24 hours before applying an
oil-base finish.
Clean Up – Clean tools and equipment immediately after use
with soap and water. Use water or vinegar-soaked rag to wipe
off any drips or spills on unintended surfaces immediately.
Storage – Store unused portion in the closed, original labeled
container.

Safe Handling
During preparation and application, wear rubber or plastic- coated
gloves and safety goggles. If applying with a sprayer, wear a
properly fitted, NIOSH-approved respirator. Care should be
taken to cover any exposed aluminum surfaces to
prevent discoloration, as this product is corrosive to metal.
