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.

** Cohesive failure

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 Backer-

Rod. 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

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.

CONCRETE, STONE, AND OTHER MASONRY

Clean by grinding, sandblasting, or wire brushing to expose a sound surface free of contamination and laitance.

WOOD

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.

METAL

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

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.

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.

Clean Up

1. Immediately after use, clean equipment with

Reducer 990 or xylene. Use proper precautions when handling solvents.

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

For Best Performance

• Do not allow uncured Ultra to come into contact with alcohol-based materials or solvents.

• 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.

• Ultra can be applied below freezing temperatures only if substrates are completely dry, free of moisture, and clean. Contact Technical Service for more information.

• Do not use as a cap, heel, or toe bead for exterior glazing. Refer to the Sonolastic ® product data sheet (Form No. 1026309).

Service (1-800-433-9517) to verify the most current version.
