Data Sheet


Spectrem Simple Seal is an ultra-low modulus, preformed silicone extrusion specifically designed to have high elongation properties. Simple Seal is typically bonded with Spectrem 1 or Spectrem 2 Silicone Sealant to a wide range of substrates to provide a watertight seal. Questions? Contact Us.

Simple Seal is designed for both new construction and restoration work involving window perimeter, EIFS joints, parapet walls, skylights, aluminum window seals, transition seals, curtain wall joints, sheet metal roof joints, and other lap joints.

Do not apply on damp or contaminated surfaces.
Do not use clear silicone sealant for the application of Spectrem Simple Seal.
Simple Seal should not be used under the following conditions:
• Below grade or below water line applications
• Joints where physical abrasion and abuse may occur, such as traffic joints
• In association with building materials that release oils, plasticizers or other material

Surface Preparation:
Surface 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.

Apply masking tape to the substrate surface at the width edges of the Spectrem Simple Seal to provide a clean edge.

Select the width of Spectrem Simple Seal wide enough so that the ridges are fully encapsulated by the sealant when installed over the joint. Apply Spectrem 1 or Spectrem 2* to each side of the joint with beads large enough to encapsulate the width of the ridges. Immediately embed the Spectrem Simple Seal into the wet sealant. Using a roller, apply consistent pressure to ensure uniform contact. Remove masking tape and any excess sealant.

Custom color matching is available. Please contact your sales representative or Customer Service representative for assistance. Lead times and costs will vary based on the request.
