Applying Microne Plus Medium with Glass Crystals

Mixing the 1st Coat of Microne Medium with Glass Crystals

Microne Medium 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.

Then add Microne Plus Comp B to the Microne Medium at a ratio of 500ml Microne Plus Comp B : 10kg Microne Medium and mix well.

Finally, add 1kg Glass Crystals & mix gently on a slow speed.  Take care not to mix too aggressively as this could cause the Terrazzo flakes to break down.

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

Applying the 1st Coat Microne Medium 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

The microcement is pre-mixed and the colour has been added to the tub, so all you need to do is give it a good mix to Tensure the colour is evenly distributed. hen add 500g Microne Plus to 10kg Tub of Microne & mix well with a microcement mixer. That’s a mix ratio of 1:20.

Once the Microne Plus has been added to the tub, you’ll have around 2 hours working time, so only mix it when you’re ready to use it.  And mix in batches if you have a large area.

Do not add Glass Crystals to this mix.

Applying 2nd Coat Microne Medium

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 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.
