Safety Precautions

Apply and cure in a well-ventilated area. Wear gloves.


Use between -35°F (-37°C) and 140°F (60°C). Protect work area. Surfaces must be clean, dry and free of old caulk, grease, dust and other contaminants. Note: Paint will not adhere to silicone. If desired, paint items prior to gluing. Remove cap. Puncture inner seal with other side of cap. Attach nozzle and cut to desired bead size (3 oz. tube only).


As an adhesive: Apply to one of the surfaces to be bonded. When bonding rubber or plastic surfaces, lightly roughen surface for best results. Press materials together. If possible, clamp parts together for full cure time of 24 hours.

As a sealant: Apply with a steady pressure, forcing sealant into the joint. Tool within 5 minutes. Do not use in joints deeper than 12 mm (1/2") without the use of a backer rod. Use in joints between 1/4" and 3/4" wide. For aquariums: Apply a 1/4" bead to the edge of glass, covering the thickness of the glass edge. Set glass on base and repeat procedure for all sides. All joints must be glass to sealant to glass with no entrapped air bubbles. Apply additional sealant to inside joints. Do not use in aquariums larger than 30 gallons (114 L) and/or aquariums containing water greater than 18" (46 cm) in height.


Clean tools and adhesive residue immediately with mineral spirits. Cured sealant may be carefully cut away with a sharp-edged tool.
