PWP (Penetrating WeatherProofer)
Advantages
PWP is an advanced formula water repellant treatment for stone, brick
and other masonry surfaces. Compared to most weatherproofers, it has
numerous advantages. Instead of coming as a ready to use product, containing
a high percentage of chemical solvents, PWP is a pure concentrate, and
to be used, it is mixed with water. PWP is not only easier to store,
handle and cheaper to ship than most weatherproofers, but because it
eliminates the need for chemical solvents, it is also |

| • Much less expensive to purchase |
• Non-flammable after mixing |
| • V.O.C. compliant |
• Environmentally friendly |

| Solvents do not offer water repellency
to treated surfaces. They simply act as carriers. After permitting the
silicone polymers to be absorbed, they simply evaporate away. Moreover,
solvents add greatly to the price of weatherproofers, and they present
a fire and explosion hazard during application. Solvents are also volatile,
releasing fumes which are dangerous to breath and destructive to the
environment.
Advanced Protection
Like all advanced weatherproofers, PWP works by penetrating into the
masonry substrate. It is not topical. After being absorbed, PWP establishes
a powerful chemical network within the masonry pores, keeping moisture
out. Besides keeping treated surfaces dry and making it easy to clean,
because PWP does not block the pores, it permits essential vapor transmission.
Concentrate Formula
Advanced Formula
Like any advanced formula WeatherProofer, PWP works invisibly and permits
surfaces to breath, but because it comes as a concentrate does not mean
it performs any less well than solvent-based weatherproofers. In fact,
PWP's advanced micro emulsion technology meets or exceeds all commonly
accepted standards for... |
| |
| • Alkali resistance |
• Vertical water repellency |
| • Chloride ion intrusion |
• Horizontal water repellency |
| • Vapor Permeability |

| Technical Data |
Appearance/Odor: Amber colored liquid with strong solvent
aroma.
Packaging: Available in quart metal cans, 1 gallon metal
cans, 5 gallon pails and 50 gallon drums
Minimum Temperature for Application: 50ºF
V.O.C.’s: 28 g/liter
Storage/Shelf Life: Keep material sealed in airtight
factory containers and store in a cool dry place. When properly
stored, material will keep for a minimum of 1 year from the date
of purchase
Coverage: This will vary depending on the porosity of
the surface, somewhere between 100 and 250 sq ft. per gal. of
mixed product can be expected.

| |
| DANGER: This material is flammable in its concentrate form.
Mix only in a well ventilated area away from any form of spark or ignition
source. |

Precautions
Adjacent areas must be properly protected when using PWP. Cover windows
and all adjoining non-masonry surfaces with plastic sheeting and tape.
Also prevent PWP from coming in contact with vegetation.
Preparations
Surfaces should be clean, dry and absorbent before sealing with PWP.
If surfaces are not new, they should be cleaned with EZKleen first.
Using EZKleen will insure PWP achieves maximum penetration.
Directions |
| 1. |
For vertical surfaces, mix 1 part PWP with 9 parts water by volume,
and for horizontal surfaces (floors) mix 1 part PWP with 5 parts
water. Do not mix any more material then will be used in
a 24-hour period. Any clean tap water is suitable. PWP is spontaneously
miscible in water and upon mixing, turns milky white. After mixing,
it is immediately ready to use. |
| |
|
| 2. |
Apply PWP in a single flood coat using a low-pressure sprayer.
An oil resistant pump up sprayer with a fan shaped spray
nozzle is recommended to be used. Allow 8 to 10 inch run down on
vertical surfaces, and on horizontal surfaces, apply sufficient
material to completely saturate the surface. Prevent puddling by
spreading out material with a deck broom. |

Note: PWP works by absorbing into surfaces. Any residue must
be removed or it will discolor the treated surface. Protect newly treated
surfaces from exposure to moisture for at least 24 hours, and PWP will
reach its maximum water repellency in 72 hours.
Limitations
PWP is a WeatherProofer. It is not a waterproofer and is not meant to
seal cracks nor be used in situations where hydrostatic pressure is
present (below grade). PWP also provides no protection against grease
and oil absorption. If oleo phobic protection is desired, POP (Penetrating
Oil Proofer) should be used.
Warning: Do not use PWP on uncured concrete. Wait at least
6 weeks from when it was installed before sealing or spotting may occur.
Safety
Ventilate enclosed areas, and wear oil resistant rubber gloves and safety
glasses. If PWP gets on skin or into eyes, rinse thoroughly with water.
