I. Description:
Back to Nature (BTN) Strip-Tox is a revolutionary new paint
remover that combines Back To Nature Safer remover Technology with
the Pre-Tox 2000 Patented "Non-Hazardous Lead Waste Removal System".
This biodegradable, non-flammable, remover contains no methylene
chloride, caustic or other harsh chemicals. BTN Strip-Tox has been
shown to render lead-based paint waste non-hazardous for disposal*.
Back To Nature Strip-Tox is a state of the art, environmentally
safe paint remover designed to remove multiple layers of paint easily
and safely. Since it is a non-caustic remover, the surface does
not need to be neutralized. It can be brushed, rolled or sprayed
on. Back To Nature Strip-Tox is cost effective and easy to use.
One product removes multiple paint layers and can render lead paint
waste non-hazardous*.
II. Types of Paint Removed:
In addition to effectively stripping lead based paint, BTN Strip-Tox
can remove most varieties of paints & varnishes which are oil or
water-based including, latex, stains, alkyds, enamels and polyurethanes.
Unlike other paint removers, BTN Strip-Tox can remove more difficult
coatings such as two part epoxy, most baked on enamels, and urethanes.
III. Surfaces:
BTN Strip-Tox works on a multitude of surfaces including
metal, wood, brick, plaster, masonry, stone, concrete, and fiberglass,
etc. BTN Strip-Tox will not damage wood (it will not discolor or
raise the grain) or affect any substrate it is applied to. It is
especially effective for stripping lead on steel.
IV. Instructions:
A. Preparation - Mask any areas not being stripped with polyethylene
and masking tape.
B. Application -

Test
Patch Since it is often hard to know the type or the amount
of paint on a surface, small test areas should be stripped
to determine proper application and the dwell time needed
for paint removal to occur.

1. For removal of multiple
layers or stubborn coatings:
Two test patches are recommended.
i) First Test Patch:
Apply the remover approximately 1/32" thick (30 mils) to the
surface-with a brush, roller, trowel, putty knife or sprayer. Can
be sprayed effectively using an airless Drill mix before sprating
- Remove filters from sprayer & spray gun - Submerge pump directly
into remover, Do not use suction hose- - Use NEW 1/4" or 3/8 " airless
hose. Use at least a 1 GPM piston spray .047 - .055 reversible spray
tip. A wet mil gauge should be used to measure thickness.
Use mineral spirits to initially flush sprayer and to clean pump.
The patch then should be checked for dwell time as follows (only
a portion at any one time): Check the patch first at 2 - 4 hours,
then periodically thereafter. As a rile of thumb, the greater the
layers of paint, the longer the product should be left on. The remover
will usually remove 8 - 12 layers of paint in 24 hours. More layers
of paint (20 +) may take longer (2 - 3 + days). Due to the nature
of certain paints such as two part epoxy and urethanes, Strip-Tox
may need more time to be effective. Average dwell time for these
coatings maybe 48 to 72 hours.
ii) Second Test Patch:
In some areas, some surface coatings (usually latex) soften easily,
causing puffing away from the surface. In these cases, the remover
works differently so the patch should be done as follows:
a). Apply a light coat of paint remover (approximately 5 - 1 0 mils)
to the surface. Wait 2 - 6 hours. If the surface starts to pull
away, the top layers have lifted from the surface and can be easily
removed with a scraper or knocked off the surface with a broom or
other device. The paint remover has penetrated through these layers
and begins to soften the remaining layers.
b). While the undercoats are still soft, apply another coat of remover
at approx. 1/32" thick (20-25 mils) to the surface. The patch then
should be checked for dwell time as follows (only a portion at any
one time): Check the
patch first at 2 - 4 hours, then periodically thereafter. As a rule
of thumb, the greater the layers of paint, the longer the product
should be left on. The remover will usually remove 8 - 12 layers
of paint in 24 hours. More layers of paint (20 +) or chemically
resistant coatings may take longer (2 - 3 + days).
c). This procedure usually applies to stripping ceilings as well.
Coverage for Strip- Tox when used mi this manner (1) and (ii) varies
between 50 and 75 + sq. ft. per gal.
3. Strip-Tox will easily cling to vertical surfaces. Use
your tool to fill detailed, intricate or grooved surfaces. For best
results apply at temperatures between 60 F and 80 F. Product activity
is reduced below a temperature of 60 F and may require additional
dwell time before all layers of paint are removed. If product freezes
let thaw and stir vigorously until product 'is consistent. No Neutralization
required Clean tools with water.
C. Suggested Removal Techniques
1. Metal Surfaces:
Agitate or rough up remover/paint on the surface with a wire
brush without attempting removal. This helps to lift bottom layers
from the surface. Use a 4in or wider razor blade scraper (wallpaper
remover) or stiff putty knife (pipe railings or irregular surfaces,
should use the putty knife) to lift remover/paint off the surface.
Use a Wire brush with Lead-Clean or light amounts of water to remove
any residue remaining.
2. Plaster Surfaces:
(i) Flat Plaster Surfaces
Easiest removal is achieved using a 4in or wider razor blade scraper
(commonly known as a wallpaper remover) to lift the remover/paint
off the surface.
(ii) Decorative Plaster (or Wood)
Use a molding scraper set to lift the remover/paint off the surface.
Use a stiff
bristle brush with Lead Clean Paint Remover Wash or light amounts
of water to remove any residue.
3 Wood Surfaces
(i) Flat Wood Surfaces - Easiest removal is achieved using a BTN
stainless steel scraper to strip remover/paint from the surface.
Use a stiff bristle brush with Lead Clean or light amounts of water
to remove any residue.
(ii) Decorative Wood - (see Decorative Plaster)
4. Masonry, Concrete Surfaces:
Remove bulk of remover/paint with a stiff putty knife or a wire
brush. Use a wire brush with Lead Clean or light amounts of water
to remove any residue remaining. Residue can also be removed with
a high pressure washer where permitted.
5. Note:
Any paint residue remaining on a surface should be removed within
a short period of time so that paint residue will not dry up and
re-adhere.
* V. Waste Disposal - Sample
waste as per federal and local regulation. Dispose of waste in accordance
with federal and local regulations. In independent tests, after
the applicator followed Back To Nature application and removal techniques
lead paint waste generated passed independent TCLP tests. However,
user must perform its own lead paint Waste tests for job specific
results. Results may vary depending up a number factors including
substrate conditions, amount of paint on a surface, specific lead
content, as well application and removal technique. User is solely
responsible for testing and classifying the waste, determining the
proper disposal method, and all disposal costs.
