ProMasonry Water Shield
is a clear, water based, low odor,
water repellent for concrete
and masonry surfaces.
Spray apply to vertical and horizontal concrete,
concrete block, concrete pavers, natural stone,
stucco and brick.
- Passes ASTM E514.
Advanced silicone technology.
Mitigates carbonation. Effective chloride
ion screen. UV stable. Unaffected by
- Water vapor permeable.
- Will not darken or alter light reflection
of substrate when properly applied to
a dry and untreated surface.
- Repels water from penetrating substrate.
Most damage to concrete, masonry and
stone is due to water entry.
- Meets all current VOC emissions
for waterproofing concrete/masonry sealer.
- Water based technology, low odor,
easy handling and clean up.
- Substrate must be clean and free of loose debris,
oils, paints, previously applied water repellents
or any substance that can interfere with
- Substrate must be dry; moisture in substrate
will reduce penetration.
- Re-point loose or deteriorating mortar,
fill all voids and cracks in mortar.
- Inspect flashing around all openings, caulking,
expansion joints and roof components to
determine condition and for evidence of water
entry. Water Shield will not prevent water entry
through cracks or voids in the substrate or
other building components.
Priming is not necessary.
Shake or stir until homogenous.
- Always apply to a test area to ensure
ProMasonry Water Shield will not affect the
appearance of the surface due to reaction
with previously applied materials or by
drawing surface contaminants into the substrate.
- For best results apply with a low pressure
sprayer using a fan tip.
For vertical applications begin at the
bottom of the wall and work up generating
a 4 - 6 inch rundown.
- Work to natural break points in the structure.
- Always keep a wet edge.
- For horizontal applications begin at one edge
and work backwards towards the opposite edge.
- Apply enough material to saturate the surface,
but do not allow material to pond.
Brush out ponded material before
surrounding area dries.
Protect from moisture and traffic for 8 hours. Material is fully cured in 14 days.
Clean tools, equipment and adjacent areas with water immediately after application. Clean glass with glass cleaner before
material can cure.
1, 5 and 54 gallon plastic containers.
18 months in unopened containers.
Protect from freezing.
Transport and store in cool, clean, dry conditions
in unopened containers.
High temperature will reduce shelf life.

- Ensure proper ventilation before
- Use NIOSH approved respirator, safety glasses,
gloves and complete skin cover during application.
- Do not apply if precipitation is forecast
within 8 hours.
- Do not apply to damp surfaces.
- Do not apply unless substrate and ambient
temperature are at least 40°F.
- Do not spray in high winds.
Always apply a sample to determine
suitability to substrate.
- Do not dilute.
- Formulated to be a single application.
Apply wet-on-wet for additional protection.
HEALTH AND SAFETY
- Product is alkaline.
- Do not ingest.
- Avoid breathing fumes.
- Avoid contact with skin and eyes.
- Refer to Material Safety Data Sheet
(MSDS) for additional information.
If swallowed contact a medical professional
immediately. Do not induce vomiting or give
anything by mouth. Only induce vomiting
if advised to do so by a medical professional.
In case of skin contact,
