SpecEtch is a spray-applied surface retarder that exposes aggregate in freshly placed horizontal concrete for decorative finishes
SpecEtch preserves the natural color of aggregate and concrete, applied at approximately 150 sq ft per gallon and cured under plastic sheeting before exposure washing.
Key Features & Benefits

Application Instructions
- Float, screed, or trowel the surface level without overworking, to avoid driving aggregate too deep
- Apply evenly at approximately 150 sq ft per gallon with a garden-type sprayer as soon as surface water has disappeared, avoiding puddles
- Cover the treated area with (preferably black) plastic sheeting, securing the edges
