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.
