Description

Uniplast, a cementitious based plaster is mixed with Acrybond "S" acrylic liquid polymer additive to form a ULC tested non-combustible base coat for Durex® EIFS family of systems. Being a cementitious plaster combined with an acrylic admixture, it is unique to the EIFS industry. It provides excellent adhesion to EPS and mineral fibre insulation, has very good workability with outstanding durability. Uniplast is available in fine, medium and coarse grades. Acrybond "S" is available in standard and winter grades.

Advantages
  • Rated ‘non-combustible’, thus meeting the National Building Code as a material to protect foamed plastic insulation for exterior applications.
  • Superior bonding to foam plastic insulation and mineral fibre insulation.
  • Excellent workability; longer open time of mixes.
  • Simplified job site mixing as no water or other additives required.
  • Consistent job site quality control.
  • Low moisture absorption rate of the mixes.
  • Higher compressive and flexural strength of the cementitious mixtures.
  • Reduced shrinkage and cracking of the mixes.
  • Excellent freeze-thaw stability
Uses

Uniplast / Acrybond "S" is to be used as a non-combustible base coat for all Durex® EIFS systems. Uniplast is available Medium and Coarse grades can be used to build up base-coat thicknesses and are ideal for use in conjunction with high-impact fibreglass meshes. Uniplast fine is to be used for finer finishing to achieve a smoother surface.
