SikaBond®-948

• Adhesive meets or exceeds all requirements of the American Plywood Association Specification AFG-01, Adhesive for Gluing Plywood to Wood Framing.
• FHA Bulletin UM-60
• ASTM D 3498

SikaBond®-948 is a high-solids polyurethane elastomer that cures by reaction with atmospheric moisture.

Weight:
10.8 lbs/gal (1.30 kg/L)

1 year when properly stored

Store in unopened containers in a cool, dry area away from direct sunlight. Storing at elevated temperatures will reduce shelf life. SikaBond®-948 remains flexible even when stored at freezing temperatures, but should be stored at room temperature for at least 24 hours before using.

Does not freeze

250°F (121°C)

Up to 1 hour

SikaBond®-948 forms a firm set in 1–2 hours and a tenacious bond overnight. Cure time varies with temperature, humidity, and the porosity of the materials joined.

1. Surfaces must be structurally sound, dry, clean, and free of dirt, moisture, loose particles, oil, grease, asphalt, tar, paint, wax, rust, waterproofing or curing and parting compounds, and membrane materials.

On Metal Surfaces
Remove scale, rust, or other coatings to expose a bright white surface.

On Concrete, Stone, or Other Masonry Surfaces:
Clean by grinding, sandblasting, or wirebrushing to expose a sound surface free of contamination and laitance.

On Wood Surfaces:
The surface must be clean and sound. Scrape away paint to bare wood.

Priming

SikaBond®-948 bonds well to most substrates; however, it is the user’s responsibility to check the adhesion of the cured adhesive on specific substrates. For further information, contact Sika Technical Services.

1. Apply by caulking gun or trowel.
2. Wearing gloves during application is highly recommended. Once material has cured it cannot be removed.
3. Because of the high strength provided by SikaBond®-948 adhesive, do not apply it as heavily as you would a conventional adhesive. Cut the smallest possible opening in the spout to render the appropriate-sized bead. Be certain to fill all gaps between materials.
4. Materials may be repositioned without loss of adhesive strength up to one hour after application.
5. When necessary, use mechanical fasteners to hold materials in place until the adhesive has fully cured.

Clean all tools and equipment immediately after use with a dry cloth; Xylene, mineral spirits, or acetone may also be used. Cured material must be mechanically removed.
