.DESCRIPTION AND USES .
WaterTite
®
Polyurethane Sealant is a high performance,
low modulus, single component, moisture-cured modified
polyurethane joint sealant. It is designed to fill deep cracks
and holes, seal dynamically moving joints such as
expansion and control joints, precise concrete panel joints,
tilt-up panel joints, curtain wall joints and perimeter
caulking to windows, doors and panels. It is suitable for
use on concrete block, cast-in-place concrete, stucco, tilt-
up, exposed aggregate and slump block. Polyurethane
Sealant can be used on basement and cellar walls,
expansion and control joints, curtain wall joints, windows,
doors, panels, fountains, reflecting pools, planters, canals,
retaining walls and privacy fences.
.FEATURES .
 Flexible joint filler - remains flexible over time
 Fills deep cracks and holes
 Excellent adhesion – does not diminish over product
life
 Seals and waterproofs

.PRODUCT APPLICATION .
SURFACE PREPARATION
IMPORTANT – The joint surface must be free from dirt,
dust, oil and loose particles. The joint must be sound,
clean and dry. The joint surface may require scraping or
wire brushing to remove loose mortar or previous
coatings, or abrasive blasting or grinding to remove
laitance, release agents or masonry waterproofing sealers.
WARNING! If you scrape, sand or remove old paint, you
may release lead dust. LEAD IS TOXIC. EXPOSURE TO
LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS
BRAIN DAMAGE, ESPECIALLY IN CHILDREN.
PREGNANT WOMEN SHOULD ALSO AVOID
EXPOSURE. Wear a NIOSH-Approved respirator to
control lead exposure. Clean up carefully with a HEPA
vacuum and a wet mop. Before you start, find out how to
protect yourself and your family by contacting the National
Lead Information Hotline at 1-800-424-LEAD or log on to
www.epa.gov/lead.
PRODUCT APPLICATION (cont.) .
JOINT DESIGN
Polyurethane Sealant may be used in any horizontal or
vertical joint design in accordance with accepted
architectural/engineering practice. Joint width should be 4
times the anticipated movement, but not less than ¼” (6.4
mm) wide.
JOINT DIMENSIONS
For joints ¼” (6.4 mm) to ½” (12.7 mm) wide, the width
and depth ratio should be equal. Joints that are ½” (12.7
mm) wide or greater should have a sealant depth of ½”
(12.7 mm). Minimum joint size is ¼” by ¼” (6.4 mm by 6.4
mm).
APPLICATION
Apply only when air and surface temperatures are
between 40-120°F (4-49°C). It is strongly recommended
the material temperature be at least 50°F (10°C) prior to
use. Colder material will require more effort to dispense
material from the cartridge. Insert Polyurethane Sealant
tube in a conventional caulk gun. Cut the plastic tip on an
angle to the desired opening size. Puncture the foil inside
plastic tip. Dispense the material into cracks. Apply to
cracks ½” wide or less. Cracks over ¼” in depth must be
filled with backing material or filler before applying
Polyurethane Sealant. Use a putty knife to level and
smooth the surface. A topcoat can be applied after the
sealant has cured for 72 hours.
TOOLING AND CLEANING
Tooling is recommended immediately after application to
ensure firm contact with the joint interface. Dry tooling is
preferred. To clean-up, use xylene or paint thinner while
sealant remains uncured. KEEP OUT OF REACH OF
CHILDREN.
LIMITATIONS
Do not apply over damp or contaminated surfaces. Use
with adequate ventilation.
