How to Apply
Joint Preparation
1. The number of joints and the joint width should
be designed for a maximum of ±25% movement.
2. The depth of the sealant should be 1/2 the width
of the joint. The maximum depth is 1/2"
(13 mm) and the minimum is 1/4" (6 mm).
Maximum recommended joint width is 1-1/2"
(38mm). Refer to Table 1.

Test results are averages obtained under laboratory conditions. Reasonable variations can be expected.
3. In deep joints, the sealant depth must be
controlled by Closed-Cell Backer-Rod or Soft BackerRod. Where the joint depth does not permit the use
of backer-rod, a bondbreaker (polyethylene strip)
must be used to prevent three-sided adhesion.
4. To maintain the recommended sealant depth,
install backer-rod by compressing and rolling it into
the joint channel without stretching it lengthwise.
Closed-Cell Backer-Rod should be about 1/8" (3
mm) larger in diameter than the width of the joint to
allow for compression. Soft Backer-Rod should be
approximately 25% larger in diameter than the joint
width. The sealant does not adhere to it, and no
separate bondbreaker is required. Do not prime or
puncture the backer-rod.
Surface Preparation
WOOD
Surfaces must be structurally sound, fully cured, dry,
clean, free of dirt, moisture, loose particles, oil,
grease, asphalt, tar, paint, wax, rust, waterproofing or
curing and parting compounds, and membrane
materials.
New and weathered wood must be clean and sound.
Scrape away loose paint to bare wood.
Any coating that cannot be removed must be tested
to verify adhesion of sealant or to determine an
appropriate primer.
CONCRETE, STONE, AND OTHER MASONRY
METAL
Clean by grinding, sandblasting, or wire brushing
to expose a sound surface free of contamination and
laitance.
Remove scale, rust, and coatings from metal to
expose a bright white surface. Remove protective
coatings as well as any chemical residue or film.
Aluminum window frames are frequently coated with
a clear lacquer that must be removed before the
application of Ultra. Any coating that cannot be
removed must be tested to verify adhesion of sealant
or to determine an appropriate primer. Remove any
other protective coatings or finishes that could
interfere with adhesion.

Priming
Clean Up
For Best Performance
1. Special circumstances or substrates may require
a primer. It is the user’s responsibility to check the
adhesion of the cured sealant on typical test joints at
the project site before and during application. Refer
to product data sheet on Primer 733 or 766 (Form
No. 1017962) and consult Technical Service for
additional information.
1. Immediately after use, clean equipment with
Reducer 990 or xylene. Use proper precautions when
handling solvents.
• Do not allow uncured Ultra to come into contact
with alcohol-based materials or solvents.
2. For immersion applications, Primer 733 must
be used.
3. Apply primer full strength with a brush or clean
cloth. A light, uniform coating is sufficient for most
surfaces. Porous surfaces require more primer;
however, do not overapply.
4. Allow primer to dry before applying Ultra.
Depending on temperature and humidity, primer
will be tack free in 15 – 120 minutes. Priming and
sealing must be done on the same work day.
Application
1. Ultra comes ready to use. Apply by professional
caulking gun. Do not open cartridges or sausages
until preparatory work has been completed. In cool
or cold weather, store at room temperature for at
least 24 hours before using.
2. Fill joints from the deepest point to the surface by
holding a properly sized nozzle against the back of
the joint.
3. Dry tooling is recommended. DO NOT use soapy
water or solvents when tooling. Tooling results in the
correct bead shape, a neat joint, and maximum
adhesion.
2. Remove cured sealant by cutting with a sharpedged tool.
3. Remove thin films by abrading.
Curing Time
The cure of Ultra varies with temperature and
humidity. The following times assume 75° F (24° C),
50% relative humidity, and a joint 1/2" width by 1/4"
depth (13 by 6 mm).
Skins: overnight or within 24 hours
Functional: within 3 days
Full cure: approximately 1 week
Immersion service: 21 days
• Do not apply polyurethane sealants in the vicinity
of uncured silicone sealants or uncured
Sonolastic® 150 or 150 Tint Base.
• Ultra should not come in contact with oil-based
caulking, silicone sealants, polysulfides, or fillers
impregnated with oil, asphalt, or tar.
• All horizontal applications require the use of
Primer 733.
• Protect unopened containers from heat and direct
sunshine.
• In cool or cold weather, store container at room
temperature for at least 24 hours before using.
• When Ultra is to be used in areas subject to
water immersion, cure for 21 days at 70˚ F (25˚
C) and 50% relative humidity. Allow longer cure
time at lower temperatures and humidity.
• Do not use in swimming pools or other
submerged conditions where the sealant will be
exposed to strong oxidizers. Avoid submerged
conditions where water temperatures will exceed
120˚ F (50˚ C).
• Lower temperatures will extend curing times.
• Do not apply over freshly treated wood;
treated wood must have weathered for at
least 6 months.
SONNEBORN® PRODUCT DATA
ULTRA
• Substrates such as copper, stainless, and
galvanized typically require the use of a primer;
Primer 733 or 766 is acceptable. For Kynar
coating use Primer 733 only. An adhesion test is
recommended for any other questionable
substrate.
Health and Safety
First Aid
ULTRA
• Ultra can be applied below freezing temperatures
only if substrates are completely dry, free of
moisture, and clean. Contact Technical Service
for more information.
Risks
In case of eye contact, flush thoroughly with water for
at least 15 minutes. SEEK IMMEDIATE MEDICAL
ATTENTION. In case of skin contact, wash affected
areas with soap and water. If irritation persists,
SEEK MEDICAL ATTENTION. Remove and wash
contaminated clothing. If inhalation causes physical
discomfort, remove to fresh air. If discomfort persists
or any breathing difficulty occurs, or if swallowed,
SEEK IMMEDIATE MEDICAL ATTENTION.
• Do not use as a cap, heel, or toe bead for
exterior glazing. Refer to the Sonolastic® 150
product data sheet (Form No. 1026309).
• Make certain the most current version of
this data guide is being used; call Customer
Service (1-800-433-9517) to verify the most
current version.
• Proper application is the responsibility of
the user. Field visits by BASF personnel
