Directions for Use

  • Grind substrate with course grit diamonds. Surface must be clean, dry, free of laitance and sound.  If FC sheet over timber, caulk joints to ensure no leakage. Generally ensure compliance to the Australian Tiling Standards.

  • Shoot levels (if required) and place edge strips. Maximum panel size 6m x 6m interior, 4.5m x 4.5m exterior with perimeter edge joints.

  • Pre-fill any trenches to ensure maximum depth 30mm.

  • Using a thick paint roller prime with CC Floor Primer (1kg + 1L = 8 sqm) the day prior and again just before pouring.

  • Using a high-shear concrete mixer empty 20kg bags and mix dry for 1 minute. Evenly and gradually add clean water, pre-blended with CC Admixture concrete conditioner at the noted doses and mix for a minimum of 2 minutes. Stop mixer and see if mix consistency is such that it starts to self-level after air expulsion. Add additional water in 100ml increments.

  • Try not to mix longer than 6 minutes. Don't clean mixer between batches.

  • Discharge and spread evenly (can use CC Screed Box), roll with spiked roller, check flatness and thickness.

  • Spray CC Film evaporation retarder immediately after placement of each panel (1l = 8 sqm).

  • After initial set (when able to walk on, usually next morning) spray CC Curehard curing compound and let cure a minimum of 5 days, preferably 10 days minimum.

  • Coarse grind until aggregate is exposed to desired level (approx. 1.5 - 2 mm) and re-apply CC Curehard using a spray and microfibre applicator, let dry. Complete medium grind, re-apply and fine grind. Run 100 resins.

  • Grout - dampen substrate with coloured CC Floor Primer sprinkle CC Pinfix coloured nano-cement and run with grouting plates or 100 resins. Manually check for any remaining visible airholes and rub with a 100 block. Do only 3 - 4 sqm at a time.

  • Remove surface grout with 100 resins. Spray CC Lithium Super Hardener and spread with a microfibre applicator. Keep wet for 10 minutes, wet mop off.

  • Continue to complete the honing/polishing process to the desired look or P rating. It is important to remove all dust continually through the process.
