UZIN PE 460 Premium Plus - Moisture Vapor Retarder / Surface Strengthener

2-component reaction resin

Two component epoxy resin moisture vapor retarder for concrete substrates with high residual moisture. UZIN PE 460 can also be used as a surface hardener for absorbent substrates and as a bonding agent.


  • Interior & exterior use
  • Use as a MVR over mechanically prepared concrete substrates up to 100% RH*
  • Surface consolidation of weak substrates
  • Bonding over abraded ceramic tile, stone and terrazzo surfaces, existing substrates with adhesive residues (including water soluble adhesive residues), smoothing compounds, certain metals and non-absorbent surfaces
  • Use with UZIN KR 518 two-component joint filler 
  • Fast-track installations with the addition of UZIN Epoxy Accelerator* (3.5 hr. dry time)
  • Use with radiant floor heating systems (obtain technical advice)

*See “Application Instructions” for additional information.
