Choosing the Best Surfaces for Swimming Pools/Hot Tubs
Because the proucts in this kit are very strong, it can only be applied to surfaces that have a minimum compressive strength of 25N/mm2 and a Tensile Strength of 1.5N/mm2.
MicroRock is waterproof both above and below, so as long the substrate is less that 10% moisture, it can be applied.
This kit is commonly used on:
- Cement Board with High Performance Primer
As with all Microcement Kits, the following rules must be followed when preparing substrates for microcement:
Surfaces should be completely smooth – as if you were going to paint onto them.
Surfaces should be well consolidated, so that any chance of movement is eliminated.
