Honed concrete, how to hone and seal concrete.
- How to protect new natural stone pool coping from the concrete pour.
- What type of concrete mix, finishing requirements the contractor needs.
- Pouring, placing and finishing concrete ready for honing.
- Grinding the concrete to a 30grit diamond size usually helps slip ratings.
- Care required around the new natural stone pool coping.
- Using Pro Seal 896 helps to cure and protects from stains until you grind.
Pre-sealing the natural stone coping tiles helps prevent staining and marking during the placement and finishing of the concrete.
Concrete cement colours and aggregate sizes and types will vary. As a rule request a higher strength mix, usually 32 Mpa. Ask your concrete to be careful edging pressure and screed mark depressions, the concrete needs to be flat. All sections need to fall in one plane, strip grates are better than small round grates. My personal finish is with a rotary trowel to compact the fines reducing small air voids. All of these things will affect the finish and how much grinding will be required for an even exposure of stone.
Always use a good grinding contractor with good machinery with at least 5 years grinding experience. They should be using metal bond diamonds and cut the finish at less than 60 grit around an outdoor area for non-slip purposes. Check building codes always for outdoor area requirements. In this case, we finished at 30grit because this will be a pool area, external wet areas can be hazardous for running and slipping.
We applied Pro Seal 896 to the coping tiles in the first video and now to protect concrete from stains prior to honing. This also helps cure the concrete better, before the grinding process 1 week later. Watch the video below and feel free to add comments…
