Technical Specifications

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, then pour into sprayer tank. If
using a brush or mop, pour product into a 2-1/2 gallon 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 – Brush or Pressure Wash
Briefly scrub surface with a Wolman WOODWORX
®
Deck
Brush or other stiff, synthetic, short-bristle broom or brush,
using moderate pressure
OR
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. Move lengthwise with boards to avoid
cut marks across grain.
Either technique helps ensure old coating is entirely
dissolved and removed.
Step 4 – Rinse
If pressure washing is not employed, after brushing, 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 2-4 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 bleed
stains.
Recommended Number of Coats – APPLY ONE (1)
COAT, and allow to sit for ENTIRE recommended time of 15
minutes. Fresh coatings, 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. (DeckStrip is
packaged in a “bonus” 1.32 gallon size, which will cover
approximately 200 sq. ft).
Dry Time – Allow wood to dry thoroughly before 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.
Technical Data
Active Ingredient: Sodium Hydroxide
pH: 13.0 minimum
Biodegradable: Active ingredient biodegrades into
inert chemicals
Weight per Gallon: 8.9 +/- 0.2 lb./gal.
Viscosity: 450-550 cps; Spindle #2 @ 6 RPM
Compatibility: This product will strip weathered oil and latex
(water-base) coatings, but is not designed to strip 100%
acrylic stains and paints. Once dry, surfaces stripped with
this product may be coated with oil or water-base water
repellents, transparent finishes, colored stains or paints.
Safe Handling
During preparation and application, wear rubber or plastic-
coated gloves and safety goggles. If applying with a sprayer,
wear a NIOSH-approved full-face respirator with an organic
vapor cartridge and N-95 pre-filter. Care should be taken to
cover any exposed aluminum surfaces to prevent
discoloration, as this product is corrosive to metal. DO
NOT MIX WITH ANY OTHER PRODUCTS, especially those
containing chlorine or bleach (sodium hypochlorite). Rinse
grass and plants with water after exposure
Precautions
DANGER: MAY BE FATAL IF SWALLOWED. CAUSES
SEVERE BURNS. CONTAINS SODIUM HYDROXIDE. May
be harmful if swallowed. Causes eye and skin irritation.
Prevent contact with eyes and skin. During preparation and
application, wear rubber or PVC gloves and safety goggles.
Wash thoroughly after handling. May cause respiratory and
throat irritation. Do not breathe spray mist. If applying with a
sprayer, wear a properly fitted, NIOSH approved respirator.
Use only with adequate ventilation. KEEP OUT OF REACH OF
