Applying Microdur Medium with Terrazzo Flakes

Mixing the MicroDur Medium with Terrazzo

You will need 20kg of MicroDur Medium with Terrazzo to complete 1 coats over 10m2.

To mix 1 x 10kg batch, measure 2.5l – 3.0l Water using a measuring jug.

Pour the Water into your mixing bucket, and mix in the Colour for 10kg MicroDur Medium.

Use the Water to rinse out all of the colour from the bottle.

Add 10kg MicroDur and mix thoroughly.

Then add 1kg Terrazzo Flakes to 10kg MicroDur 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 Microdur Medium with Terrazzo

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 terrazzo across the area so that you have full coverage and drag marks are minimised.

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 24 hours.

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

Sand with 40 grit sand paper to reveal the terrazzo 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 terrazzo, 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.
