Bathroom & Sanitary Silicone Sealant

Description

ALSEAL AS-206 is a one-component, mildew-resistant, 100% neutral cure silicone sealant designed for use in high humidity and high-temperature areas. The fungus resistance of this sealant has been tested on ASTM G21-02 and found to have a strong fungistatic effect. It cures to form a strong, flexible, watertight seal on most common building materials for wet areas. It is tested for low VOC content following SCAQMD Rule 1168 (Application of Adhesives and Sealants).

Bathroom & Sanitary Silicone Sealant is widely use for grouting ceramic tiles, bedding tile accessories, and sealing showerheads, tubs, rimless, sinks, kitchen, and bathroom fixtures.

• 100% neutral silicone
• ASTM G21 tested

Usage Instructions

1. Surfaces must be clean, dry and free of dirt, grease, oil or water.
2. Surfaces should be cleaned with alcohol, M.E.K. or other suitable solvents. Do not use soap or detergent.
3. For a neat finish, apply masking tape and remove it before sealant skins over.
4. Cut nozzle at 45° angle to the desired bead-width and apply to a substrate with a cartridge gun.
5. Tool the sealant within 10 minutes of extrusion before it skins. Tack-free in 20 minutes.
6. Uncured sealant can be cleaned up with mineral spirits.

Clean Up

• Wet sealants can be cleaned up with acetone or mineral spirits.
• Cured sealants can only be removed mechanically.

Joint Design

• The specified sealant bead size should be calculated to comply with the compression and extension capabilities of the sealant in relation to the anticipated joint width due to expansion and contraction.
• Generally, calculation of the width sealant bead should be computed on the basis of a maximum ±20 %movement capability
• Minimum joint depth should not be less than 6 mm to accommodate movement.
• Sealant design joint width-to-depth ratio should be 2:1.
