Installation Tips


  • Before the installation, make sure that surfaces are clean, dry and free of any loose particles.
  • With a 3/8″ trowel apply the approved adhesive (or base coat) to cover the backside of the detail.
  • For proper adhesion stick the detail immediately, while the adhesive is still wet. Some details may require a mechanical fastener to prevent sliding. When adhesive has completely dried up, prepare the surface for the finish coating by taking the screws out carefully or by putting the base coat over the screws.
  • When connecting two or more details use fiber mesh and base coat at the joint level.
  • For a smooth and leveled joint, sand the excess material from the details.
