Applying Microne Coarse
Follow the directions below to apply the Microne Coarse. The colour has been added to the tub for you.
Standard consumption for Microne Coarse is 10kg for 10m2, one coat. The pot life of Microne is unlimited, so you can take your time applying it.
You will need a microcement mixer and a flexible trowel.
Mixing Microne Coarse
This is pre-mixed with the colour in the tub, all you need to do is give it a mix before you start to loosen it and make sure the colour is evenly distributed.
To do this, mix thoroughly with a microcement mixer head attachment on a cordless drill. If it still feels stiff, you can add up to 10% water to loosen & mix further. That’s a maximum of 1l per 10kg.
Let the mixture rest for a few minutes before applying.
Apply Microne Coarse
Use the same technique as you did for the base coats. It’s important that you go as thin as the grain with Microne Coarse.
Here’s a reminder of the technique:
Using a Microcement Trowel, work your way out from one corner creating a random edge pattern. Keep trowel movements small and random, avoid long sweeping arches – as these will show through to your final finish.
Use the grain in the microcement as your level – if you apply the microcement thicker than the size of the grain, the finish won’t be as strong and will require a lot more sanding. Run the trowel back over each section that you have put down to smooth it out and remove excess product.
Completely cover each surface without stopping. For complete rooms, start with ceilings, then walls from left to right (or right to left) and then the floor.
Run your finger or a corner trowel along internal corners to push the microcement into the corner and then gently trowel away the excess product.
Leave to Dry
Once you have completed the coat, you’ll need to leave it to dry before sanding and applying sealers. This will take at least 12 hours.
Sand with 40/80 Grit Silicone Carbide Sanding Disc
Once the Microcement is fully dry, gently & evenly sand the surface of the microcement with a 40 or 80 grit paper to remove any rough patches and drips. It should be flat from the trowel so you shouldn’t need to sand it too much at this stage.
Vacuum the surface to remove all dust and debris. Do not wet the microcement.
