Vertical cylindrical roll of black underlay material photographed against a white background. The textured roll stands upright and features a blue-and-white product label near the top with the text 'UX 500 MICROGUARD' and a company logo. The material appears to be a decoupling membrane or protective floor underlay with a felt-like surface. The clean studio shot isolates the product for catalog use.

UX 500 MicroGuard Tile and Stone

Super Thin Uncoupling Membrane

Applications

  • Tile and stone interior installations for wet and dry areas
  • Over UZIN priming and surface preparation systems
  • Single-layer tongue-and-groove plywood subfloors 5/8” (15.75 mm) or thicker on joists up to 19.2” (49 cm) O.C., eliminating backerboards (See important notes)
  • Concrete and gypsum substrates to isolate the tile from the floor assembly
  • Once young concrete substrates are walkable and there is no standing water
  • Crack isolation underlayment to handle up to 1/8” (3 mm) in-plane movement 
  • Suitable for most radiant heat floor applications (see substrate requirements) 
  • Residential, commercial, and industrial applications
  • Compatible with UZIN CX 15, 20, 30, 33, and 38 cement-based tile-setting mortars and UZIN TR 400 resin-based setting mortar
  • For topical waterproof integrity, UZIN WP Seam Tape bonded with UZIN CX 15, 20, 30, 33, and 38 or UZIN HS 200 is recommended for seams and perimeter details. It is also compatible with UZIN HS 100 for seams and perimeter details

Properties

  • Installer-friendly - Extremely lightweight, easy to carry, fit, cut, & flatter surface to kneel and trowel on
  • No Memory Effect - Rolls out flat immediately
  • Thin Profile - Reduced overall thickness & uses ~50% less thin-set than geometrically configured membranes
  • Fast-Track Installation - Can be installed over young concrete & gypsum substrates with tile able to be installed immediately on top of the membrane
  • Underlayment Grade - Replaces traditional tile backerboards over single layer plywood or OSB subfloors
  • Waterproof and Vapor Management - Allows vapor to equalize from the underside, but waterproof from the top when seams and perimeter are treated

* At 70 °F (21 °C) and 65% relative humidity.
