Spectrem 3: Tremco 20oz Sausage Silicone


  • Low polar attraction to dirt makes buildings easier to clean and maintain.
  • Low-modulus and low Shore A hardness reduce chance of EIFS substrate failures when compared to applications with medium-modulus sealants.
  • Primerless adhesion to most porous substrates.
  • Extended tooling time and workability in high temperatures.
  • Ease of use reduces the risk of application failure.
  • Matte finish affords an aesthetically pleasing appearance with EIFS and stone substrates.
  • No-cure inhibition with Spectrem1, Spectrem2, Dymonic®FC when applied “wet-to-wet,” minimizing the chance of leakage when sealants used for 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.

Spectrem 3 has a patented chemistry that has been specifically formulated to seal porous stone, EIFS, metal panels, masonry and pre-cast concrete joints.

Closed-cell polyethylene backer rods are preferred as a joint backing material 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 three-sided adhesion. Joint backing must be dry at the time of sealant application.

Surfaces must be sound, clean, and dry. Contact surfaces should be free of loose dirt, dust, oils, and any other contaminants. Tremco recommends that air temperatures be 40 °F (5 °C) or above before applying any sealant. If colder weather is imminent, please refer to the Tremco Guide for Cold Weather Applications at www.tremcosealants.com.

Tooling is recommended immediately after application to ensure firm, intimate contact with the joint interface. Dry tooling is preferred. Cleaning can be accomplished with solvents such as IPA, MEK, Toluene or Xylol while sealant is in an uncured state.

• Do not apply to damp or contaminated surfaces.

• Use with adequate ventilation.

• Not intended for continuous water immersion.
