Poly Modified Waterstop is a one component, polymer modified,
cement coating designed to waterproof/dampproof concrete and
masonry. It may be used above or below grade. Poly Modified
Waterstop consists of polymer, cement, fine sand and other
propriety chemicals. The waterproof additives are crosslinked
with the polymer providing long-term performance. Poly Modified
Waterstop produces premium-waterproofing properties combined
with the durability of a cement sand coating. Poly Modified
Waterstop is available in gray, white and special order colors.
The finish of the cured coating is a light texture. For a
smooth surface waterproof coating use Orco Blended Products
Poly Modified Waterstop Paint.
Uses: As a waterproof
and decorative coating for above or below grade masonry and concrete.
Waterproof/dampproof basement walls, retaining walls, planters,
fountains and reservoirs. Decorate and waterproof block walls, pools,
stucco and concrete structures.
Advantages: Poly Modified Waterstop
produces a premium waterproof coating. The cement sand coating produces
a decorative coating that is much more durable than paint. The polymer
enhanced cement-to-cement bond produces a coating, which actually
becomes part of the substrate. Poly Modified Waterstop is one-component
system add only water. Being water based it is easy and safe to
apply and clean up.
Technical Data: Poly Modified Waterstop meets the 1997 Uniform Building
Code as a dampproof coating under the category of acrylic modified
cement coatings in Appendix Chapter 18 section 1824. Test results

Poly Modified Waterstop is available in weather resistant paper
bags in 50 lb. weights. Store in a cool dry area. Shelf life is
approximately I year.
Coverage: Approximate coverage per 50 lb. bag is 200 square feet
per coat 2 coats required for good waterproofing properties. Coverage
figures are approximate only. Sufficient material must be applied
to completely fill and seal all holes, pores and voids. Coverage
may vary due to substrate and job requirements.
Surface preparation - All surfaces must be clean and structurally
sound. There must not be any dirt, grease, oil, and efflorescence,
curing compounds or any type of bond inhibitors on the surface.
Dense or smooth surfaces should be roughened or primed. Mortar droppings
and other impediments should be removed prior to application. Repair
all holes, voids and cracks with a suitable repair material (i.e.
water plug, polymer patch, caulk etc.). Dampen the substrate just
prior to application no standing water.
add Poly Modified Waterstop to clean potable water (approximately
2 gallons per 50 1b. bag). Thoroughly mix the material to a pancake
batter consistency making sure all lumps are removed. Allow to stand
10 15 minutes before application. Re mix and adjust consistency
just prior to application. Do not over water material.
coating with a brush, roller, trowel or spray in 2 even coats of
approximately 200 square feet per 50 lb. bag per coat (coverage
may vary with substrate or job conditions). Extend coating over
footings. Allow I" coat to dry before applying second coat.
If coating drags during application rewet substrate, do not overwater
coating. Do not apply on frozen or frost covered substrate. In extreme
heat or wind, fog curing may be necessary.
- Do not apply when rain or freezing temperatures
(40) are expected prior to cure.
- Will not bridge moving cracks in the substrate.
- Do not apply to frozen substrates.
- Properly cure in extreme heat and wind.
Prolonged exposure to dust may cause delayed lung disease. Eliminate
exposure to dust. Use NIOSH approved mask for silica dust. Freshly
mixed materials may cause skin irritation. Avoid direct contact
where possible and wash exposed skin areas promptly. If any cementitious
materials get into the eyes, rinse immediately and repeatedly with
water and get prompt medical attention. See Material Safety data
