Applying Microne Medium Plus with Glass Crystals

Follow the directions below to apply the Microne Medium Plus with Glass Crystals.

The standard consumption for Microne Medium Plus with Crystals is 10kg for 10m2, one coat.  Expected drying time for Microne Medium is 3 hour and there is no limit on how long you can leave it between coats.  The pot life of Microne Plus is 1-3 hours, so it’s best to mix it in batches.

Mix 10kg Microne Medium with 500ml Microne Plus Comp B.

You will need a microcement mixer and a flexible trowel.

Mixing the 1st Coat Microne Medium with Glass Crystals

You will need 10kg of Microne Medium with Crystals to complete 1 coats over 10m2.

For each 10kg batch, add 500g Microne Plus Comp B to the tub.

Mix thoroughly with a microcement mixer head attachment on a cordless drill.

Then add 1kg Glass Crystals to 10kg Microne Medium & mix gently on a slow speed.  Take care not to mix too aggressively as this could cause the Crystals to break down.

Applying the 1st Coat Microne Medium Plus with Crystals

Use a Microcement Trowel and hold hold it quite flat to the surface. Don’t put as much pressure on as you did with the base coats to avoid the crystals leaving drag marks across the surface.

Gently spread the crystals across the area so that you have full coverage and drag marks are minimised.

Leave to Dry

Leave the Microcement to dry.  With crystals in the mix, this often takes more time than standard Microcement.  Allow up to 12 hours.  Drying times do vary depending on temperature and ventilation.

Mixing 2nd Coat Microne Medium

You will need 5kg per 10m2 for your final Microne Medium.

For each 10kg batch, add 500ml Microne Plus Comp B to the tub.

Mix thoroughly with a microcement mixer head attachment on a cordless drill.

Do not add glass crystals.

Let the mixture rest for a few minutes before applying.

Applying 2nd Coat Microne Medium Plus

Use this coat to glide over the previous one, filling in any imperfections as you go. Because there’s no crystals in it, you go can a lot thinner with this coat.

Leave to Dry

The microcement needs to be fully dry before sealer is applied. If not the microcement will not reach full hardness and could de-laminate.

Moisture content should be less than 5% before sealer is applied.

The timings below are for guidance only, your microcement may take longer to dry depending on temperature and humidity.

Leave Microne to dry for at least 12 hours.

Sand with 40, 80 & 120 Grit Silicone Carbide Sand Paper

Sand with 40 grit sand paper to reveal the crystals in the microcement.  This will be a lot easier with an orbital sander than by hand.

Once you have revealed a good, even spread of crystals, move onto the 80 grit sand paper and give the whole area another sand.

Finally, use a 120 grit sand paper to tidy up your wark and close in the pours.

Vacuum the surface to remove all dust and debris. Do not wet the microcement.
