ROOF & GUTTER REPAIR TAPE .jpg

Cemix A.P.R.A. is an amber-coloured, chemical release agent that reacts with cement to create a smooth, easy-to-release surface. Designed to break the bond between freshly cast concrete and formwork, it simplifies removal and protects your formwork and tools. Ideal for both DIY builders and trade professionals, A.P.R.A. helps you achieve clean, high-quality concrete finishes with less effort.

TYPICAL USES:

  • Concrete garden edging, pavers or decorative blocks

  • Driveway slabs, patios, and walkways

  • Concrete steps, curbs, and retaining walls

  • Small structural pours like foundations, columns and lintels

  • Timber, plywood, steel or plastic formwork, used in domestic or small‑scale builds

  • Tools, shuttering, machinery, handling equipment — helps prevent buildup during casting


ADVANTAGES:

  • Easy Bond-Breaking: Helps concrete release cleanly from formwork without sticking.

  • Smooth, Stain-Free Finish: Produces a clean surface with minimal blemishes.

  • Protects Formwork: Regular use on timber formwork lowers maintenance costs and extends its usable life by shielding against moisture cycles

  • Tool-Safe: Can be used on placement tools and handling equipment to prevent concrete buildup.

  • Doesn’t Interfere with Later Coatings: Doesn’t affect the bonding of paint, plaster or waterproofing products applied later.
