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.

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.
