Applying MicroDur Medium Plus with Natural Terrazzo
Follow the directions below to apply the MicroDur Medium with Natural Terrazzo.
The standard consumption for MicroDur Medium with Natural Terrazzo is 10kg for 10m2, one coat. Expected drying time for MicroDur Medium is 3 hour and there is no limit on how long you can leave it between coats.  The pot life of MicroDur is 1-3 hours, so it’s best to mix it in batches.
For each 10kg batch, measure 3.6Kg MicroDur Regular Plus Comp A + 450g MicroDur Regular Plus Comp B using a measuring jug.
Mix the A + B components into a mixing bucket, then slowly add the MicroDur Medium, mixing as you go to avoid lumps forming in the mix.
You will need a microcement mixer and a flexible trowel.
Mixing the 1st Coat MicroDur Medium with Terrazzo Flakes
You will need 10kg of MicroDur Medium with Terrazzo to complete 1 coats over 10m2.
For each 10kg batch, measure 3.6Kg MicroDur Regular Plus Comp A + 450g MicroDur Regular Plus Comp B using a measuring jug.
Mix the A + B components into a mixing bucket, then slowly add the MicroDur Medium & Natural Terrazzo, mixing as you go to avoid lumps forming in the mix.
Take care not to mix too aggressively as this could cause theTerrazzo to break down.
Applying the 1st Coat MicroDur Medium Plus 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 crushing the flakes.
Gently spread the terrazzo across the area so that you have full coverage.
Leave to Dry
Leave the Microcement to dry. This should take around 3 hours hours. Drying times do vary depending on temperature and ventilation.
Mix & Apply 2nd Coat MicroDur Plus Medium
Mix & Apply this coat in exactly the same way that you applied the 1st one.
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 MicroDur 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 natural terrazzo effect 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.
