Tremco Spectrem 4 1.5 Gallon Pail : Construction Sealant


• Tremco Universal Color Paks in 70 standard colors and no minimum purchase quantity afford color flexibility for seamless façade appearance.
• Opportunity to tint materials on-site means quick turn-around.
• A 20-yr non-stain warranty when pre-approved and tested by Tremco in accordance with ASTM C1248.
• Low polar attraction to dirt makes buildings easier to clean and maintain.
• Low-modulus and low Shore A hardness reduces chance of EIFS substrate failures when compared to applications with medium-modulus sealants.
• Primerless adhesion to most construction materials.
• Extended tooling time and workability in high temperatures.
• Ease of use reduces risk of application failure.
• No cure inhibition with Spectrem 1, Spectrem 2, Dymonic® FC when applied “wet-to-wet,” minimizing the chance of leakage when sealants abut at glazing and other façade intersects.
• Low-VOC and zero-solvent content satisfies the LEED Indoor Environmental Criteria.
• Greenguard Gold certification ensures safety for use in the most sensitive indoor environments including hospitals and schools.

Tremco Spectrem 4 is a multi-component, low-modulus, construction sealant with patented advanced silicone technology. Non-staining and low polar attraction to dirt increases aesthetic appearance. Tremco Spectrem 4 offers color
flexibility with the opportunity to tint the material on site. Contact Us.

Formulated for use in dynamically moving building joints with +/- 50% movement. Typical applications for Spectrem 4-TS include EIFS, expansion and control joints, tilt-up panel joints, precast concrete panel joints, and
perimeter caulking (windows, doors, panels).

Mix in accordance with directions on the product container label. Mixing should continue until the desired uniform color is reached. Apply with conventional caulking equipment, filling the joint completely and tool.

Expansion joints:                                                                                                                                                                                The minimum joint width (W) and sealant contact depth (C) of any silicone sealant application is 1/4” by 1/4” (6.35 mm by 6.35 mm). It is recommended that the sealant joint depth (D), when measured from the face of the sealant bead to the crown of the backer rod, be equal to one-half the sealant joint width (W), known as 2:1 width-to-depth joint ratio. For silicone sealants, the minimum sealant joint depth (D) at crown of backer rod is 1/8”(3 mm) and the maximum sealant joint depth at crown of backer rod is ½” (13mm). For joints that are wider than 1″ (25 mm), contact Tremco’s technical services or the Tremco sales representative nearest to the application site for additional support.

Window perimeter joints:                                                                                                                                                                 For fillet beads, or angle beads around windows and doors, the sealant should exhibit a minimum sealant contact depth [C] of 1/4″ (6.34 mm) onto each substrate. Proper joint backing or bond breaking must be implemented to allow the sealant to perform when exposed to joint movement.

Joint Backing:
Closed-cell polyethylene backer rods are preferred as joint backing to control depth of sealant bead. Where depth of joint will prevent use of joint backing, an adhesive- backed polyethylene tape should be installed to prevent threesided adhesion. Joint backing must be dry at time of sealant application.
