Sika MultiSeal® Plus
High Tack Ethylene Propylene Copolymer Self-Adhering Tape and Flashing Sheet

Description

Sika® MultiSeal Plus Ethylene Propylene Copolymer Tape and Flashing Sheet is a high performance, industrial grade self-adhered tape & flashing sheet. Sika® MultiSeal Plus consists of a nonrelease UV resistant TPO top film membrane laminated to at high tack, non-drying and non-hardening reinforced rubber compound with inert inorganic, non-asbestos fillers. It is specially designed for use as a waterproof barrier and thru-wall flashing membrane. Sika MultiSeal® has superior weathering characteristics and retains adhesion and elasticity for prolonged periods. Sika® MultiSeal Plus is manufactured in accordance with ISO 9001 / 14001 quality assurance system and the Responsible Care Program.

Where to Use

Sika® MultiSeal Plus Tape & Flashing Sheet is specifically formulated to seal joints and provide a waterproof barrier when properly applied over prepared substrates.

Sika® This product is not recommended for sealing PVC sheeting. MultiSeal Plus Tape & Flashing Sheet is also intended to be used as a thru-wall flashing membrane in cavity wall construction when used in conjunction with Sikagard 530 and other Sika Liquid Applied Vapor Permeable Air Barrier Systems. This product is suitable for experienced professional users only. Tests with actual substrates and conditions must be performed by the end user to ensure adhesion, function, durability, and material compatibility. Applications in volving water immersion may require special substrate pre-treatment. See the Limitations section.

The above information is offered for general guidance only, and testing for specific resistance is recommended. Advice on specific applications will be given on request.

How to Use

Application

Repair Tape - Specific advise on use as a repair tape only is available from the Technical Service Department of Sika Industry at tsmh@sika.us.com. Thru-Wall Application - Acceptable substrates are precast concrete, cast-in place concrete, concrete block, primed steel, aluminum mill finish, anodized aluminum, galvanized metal, gypsum board, wood and Sikagard® 530 Liquid Applied Vapor Permeable Air Barrier Systems. All surfaces to receive Sika® MultiSeal Plus Tape & Flashing Sheet must be clean of oil, dust and excess mortar. Strike masonry joints flush. Concrete surfaces must be smooth and without large voids, spalled areas or sharp protrusions. Concrete must be cured a minimum of 14 days and must be dry before Sika® MultiSeal Plus Tape & Flashing Sheet is applied. Sika® MultiSeal Plus Tape & Flashing Sheet is designed for permanent exposure and may be installed direct to concrete or Densglass Gold without the aid of primers or other surface conditioners. Alternatively, Sikagard® 510 or Sikagard® 530 may be used for priming. Applications to wood require the use of Sikagard® 510 or Sikgard® 530 as a primer. Material should be conditioned at room temperature for ease of application. Cut the desired length of Sika® MultiSeal Plus Tape & Flashing Sheet, remove release paper, position into place and apply positive pressure using a roller. Use care to avoid blisters or wrinkles. Overlap all joints by 2 inches. Keep Sika® MultiSeal Plus Tape & Flashing Sheet back about ½ inch from outside face of wall or veneer. At all laps, seams, penetrations, and along top edges of membrane apply a continuous bead of Sikaflex®-11 FC sealant as the termination seal. Form end dams as required with same sealant. Apply under dry conditions when air and surface temperatures are above 25 degrees F. Top or leading edge of Sika® MultiSeal Plus Tape & Flashing Sheet should be sealed with a Sikaflex Sealant to limit rainwater from migrating behind the membrane. For further advice on use as a thru-wall flashing, contact Sika Technical Services at 1-800-933-SIKA(7452).

Removal

Sika® MultiSeal Plus may be removed from tools and equipment with mineral spirit or another suitable solvent. STRICTLY FOLLOW SOLVENT MANUFACTURER’S WARNINGS AND INSTRUCTIONS FOR USE. Following use wash hands with soap and water. Do not use solvents on hands!
