Prior to application, confirm substrate moisture content, r.h. and dew point. If > 4% pbw moisture content, Sika® EpoCem® range may be applied as a T.M.B. (temporary moisture barrier) system.
Sikafloor® Terrazzo SA system must be applied by recommended experienced applicators. The following is only a brief description for the application procedures:
Primer:
Make sure that a continuous, pore free coat covers the substrate. If necessary, apply two priming coats. Apply primer by brush, roller or squeegee. For more details please consult relevant Product Data Sheet and Method Statement.
Membrane Layer:
Optionally, apply membrane layer onto the floor using rollers and immediately after application start application of reinforcing mesh to bridge static cracks or joints. Contact Sika's Technical Department for further information.
Terrazzo Epoxy Screed:
Apply the mortar/screed evenly using screed boxes, trowels, levelling boards and guide rails where necessary. After a short waiting time thoroughly compact and smoothen the mortar with a trowel or Teflon coated power floater (usually 20 - 90 rpm)..
Grinding:
Start grinding of the screed after approximately 12 hours, using 3 or 4 head mechanical grinding machines. If required, contact Sika Technical Services for advice prior to commencing grinding operations.
Grouting:
Uniformly spread Sikafloor® Terrazzo SA by using a trowel or squeegee, work well into substrate to ensure complete filling of blowholes.
Finishing:
Using a 3 or 4 head mechanical grinder with 80-120 grit, resin bonded, diamond grinding tools. Execute final grinding and polishing applications.
Sealer:
Apply sealer as the final wearing course by using a short pile roller or airless spray equipment.
