Opus Easytard TF should be spray applied to fresh horizontally cast concrete at a rate of 3.5m2 /litre immediately after finishing, avoid excessive trowelling of the concrete as this may seal the surface and negate the retarding action. Avoid application to free standing/bleed water. During the curing period, protect the treated surfaces from rain and frost. Removal should take place between 2-12hrs. The retarded matrix should be removed by hosing/brushing to expose the underlying aggregate. All equipment can be cleaned with water following application.
Opus Easytard TF should be spray applied by pneumatic spray equipment at the rate of 3-5 m2 /litre. The depth of exposure is governed by the cement content, w/c ratio, etc. Trial casts should be assessed prior to use, NB. Certain admixtures hinder retarding action, again evaluate prior to use.
