Applying Microne Base

Follow the directions below to apply the Microne Base.  Make sure you use Microne Base without colour added for your 1st base coat.  This will help to make the final colour more accurate.

The standard consumption for Microne Base is 10kg for 10m2, one coat.  Expected drying time for Microne Base is 3 hour and there is no limit on how long you can leave it between coats.  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 1st Coat of Microne Base without Colour

Use Microne Base without Colour for the 1st Base Coat.

Microne Base is pre-mixed in the tub, to loosen the mix, 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.

Applying the Microne Base

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. You should still be able to see the mesh after after applying this coat.

Completely coat 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.

Mixing 2nd Coat of Microne Base

We have added the colour to the tubs but not mixed it in.  The colour is at the bottom of the tub so shen you open the tub, it may look like there’s no colour in there at all.  But when you start mixing, it will gradually change colour to the one you have chosen.

Unlike the Top Coats, the colour for Base Coats is not an accurate match to the swatch, it’s just enough to take it in the right direction before Top Coats are applied.

To loosen the mix, 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.

Applying the Microne Base

Apply the 2nd Coat of Microne Base in exactly the same way as the 1st coat.

Leave to Dry

This should take around 3 hours but may vary depending on temperature and humidity.

Sand with 40/80 Grit Sand Paper

Once the base coats are dry and before you apply your Top Coats, you need to make sure the Base Coats are completely flat.  You need to use a strong sand paper, like Silicone Carbide, to prevent colour from the disc transfering to your work.

Flatten the Microne Base with a 40 or 80 grit sand paper. An orbital sander is ideal, but, for smaller areas, you can do it by hand.

Use the sand paper to remove ridges and drips that have dried in the microcement.

The top coats are very thin so any ridges or imperfections in the base coats will be visible in the top coats.  Take your time to get it completely flat before moving on to the next step.

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