PRODUCT DESCRIPTION
Ultra-Set Advanced ™ is a tenacious, one-part, trowel applied, elastomeric waterproofing/crack/sound isolation membrane and setting adhesive. Use Ultra-Set Advanced as a waterproofing, crack, and sound isolation membrane over properly prepared concrete; structurally-sound, exterior grade plywood (interior/dry use only); cementitious backer board; and existing, well-bonded vinyl/VCT or ceramic tile; prior to the installation of ceramic or stone tile. Ultra-Set Advanced may be used with gypsum based underlayments in dry, above grade installations with minimum compressive strengths of 2,000 psi. Follow applicable TCNA specifications for installation of tile over poured gypsum underlayments. Use Ultra-Set Advanced as a setting adhesive for ceramic or stone tiles over properly prepared concrete; structurally-sound, exterior grade plywood (interior/dry use only); cementitious backer board and existing, well-bonded vinyl/VCT or ceramic tile.

Ultra-Set Advanced contains Bostik BLOCKADE^™ antimicrobial protection, which inhibits the growth of bacteria, mold or mildew on the surface of the dried membrane; the dried membrane resists stains caused by mold.

Ultra-Set Advanced was independently tested in a controlled laboratory environment to measure the IIC (Impact Insulation Class) according to ASTM E492-04 and E989-89 and STC (Sound Transmission Class) according to ASTM E90-04 and E413-04 installed over 6 inch (152 mm) Concrete Slab Floor- Ceiling Assembly with Suspended 5/8” Gypsum Board Ceiling with Quarry Tile on Hydroment Ultra-Set Advanced Membrane.

INSTALLATION:
Read and understand data sheet completely before beginning installation. Follow applicable ANSI, TCNA and NTCA installation standards.

SURFACE PREPARATION:
Surface must be clean, dry and smooth; free of voids, projections, loose materials, oil, grease, sealers, curing compounds, waxes and all other surface contaminants that may inhibit proper bond.

Prior to application of membrane: All cracks (1/8” or less), coves, corners, drains, pipes, etc. should be treated by applying Ultra- Set Advanced with the notched-side of a 3/16” x 5/32” V-Notch Trowel. Immediately embed a 2” wide fiberglass mesh tape into the fresh material with the flat side of the trowel to achieve a flat, reinforced, uniformly thick membrane (30-mil. minimum). A minimum 6” wide coat should be applied to both sides of the joint, crack, or intersection.

All cracks greater than 1/8” should be treated, by inserting a backer rod, bond breaker tape or, fill the crack/joint with Ultra-Set Advanced or Chem-Calk 900 urethane sealant. Apply Ultra-Set Advanced with the notched-side of a 3/16” x 5/32” V-Notch Trowel. Immediately embed a 2” wide fiberglass tape into the fresh material with the flat side of the trowel to achieve a flat, uniformly thick membrane (30-mil. minimum). A minimum 6” wide coat should be applied to both sides of the joint/crack.

APPLICATION: For waterproofing, noise reduction, and crack isolation: Apply Ultra-Set Advanced using the notched side of a 3/16” x 5/32” V-Notch Trowel, immediately smooth material with flat side of trowel to achieve a flat, uniformly thick membrane with a minimum wet thickness of 30-mil (thickness of a drivers license).

As an anti-fracture/crack isolation membrane: Apply Ultra-Set Advanced using the notched side of a 3/16” x 5/32” V-Notch Trowel. Immediately smooth material with flat side of trowel to achieve a flat, uniformly thick membrane with a minimum wet thickness of 30-mil (thickness of a drivers license). The membrane should be applied to both sides of the crack/joint a minimum of the width of the tile being installed (i.e. a 12” tile should have a minimum 24” wide membrane).

As a setting adhesive: Due to its tremendous diversity, apply Ultra-Set Advanced according to Bostik’s current published literature, or consult Bostik’s Technical Service Department for application instructions.

COVERAGE: 50 square feet per gallon.

CLEAN-UP: Clean all tools and equipment with Bostik’s Ultimate Urethane Adhesive Remover, or mineral spirits before material cures. Cured urethane is difficult to remove. For cured material, use Bostik’s Ultimate Urethane Adhesive Remover Towels or Liquid.

CURING: Keep all traffic off the installation until material cures (approximately 6-12 hours). Set times are dependent upon temperature and humidity.

TILE INSTALLATION: Install Ceramic tile or stone with Hydroment Reflex, Big Tile & Stone, Single Flex, Single Flex FS, PM Thin Set; and Tile-Mate Premium or TileMate Floor & Wall mixed with Hydroment 425 Multipurpose Acrylic Mastic or 447 Flex-A-Lastic; Hydroment 100% Solids Epoxy, Hydroment 1900 Modified Epoxy or any Hydroment Ceramic Tile Mastic. Follow applicable ANSI, TCA & NTCA installation standards.

LIMITATIONS:

• Ultra-Set Advanced is not designed to be a wear surface.
• It must be covered with approved flooring materials using approved application methods.
• Ultra-Set Advanced is a “positive” waterproofing membrane only. Do not use where hydrostatic/negative water pressure can occur.
• Ultra-Set Advanced in not intended to reduce sub-floor moisture or moisture vapor transmission.
• Ultra-Set Advanced is not designed for use in joints/cracks with dynamic movement (i.e. expansion, isolation, or construction joints).
• As a waterproofing/anti-fracture/sound reduction membrane Ultra-Set Advanced is designed for movement of 1/8”, or less.
• If Ultra-Set Advanced is exposed to excessive moisture while curing, membrane may exhibit bubbles or pinholes.
• When used as a waterproofing membrane, fill any pinholes or voids with a second coat of Ultra-Set Advanced. If pinholes are excessive, cut-out affected area and replace with fresh material.
• Do not apply over surfaces below 50ºF.
• Total thickness of material should not exceed 60-mils (3/32”).
• Do not install over wet, contaminated or friable substrates.
• Do not use to bridge expansion joints.
• Do not use over cushion backed or perimeter bonded sheet vinyl flooring.
• Do not use beneath Vinyl or VCT flooring.
• Do not apply over oriented strand board, particle board, masonite, luaun, or similar unstable substrates.
• Due to the limitations of plywood as a substrate, Ultra-Set Advanced is not intended for use on plywood in exterior, wet interior, or applications subject to heavy/commercial traffic.
