Applying the 1st Coat of Microne Base

Mixing 1st Coat of Microne Base without Colour

In order to set a neutral foundation, it’s best to apply the 1^st base coat without any colour toner.  If you ordered a kit, you will be supplied enough colour toner for the 2^nd base coat only.

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 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.

Large Floor Areas

For large floor areas, you may find it quicker to use a Squeegee Trowel to apply your 1st base coat.

If you choose to do this, add 1l water (maximum) to the mix & stir well.

Pour the Microcement along the width of the room and use the Squeegee to flatten it out over the floor so that it is no thicker than the grain in all areas.

Complete around a metre before wiping the excess off the trowel and going back over the area to remove any raised lines & remove any excess product, before moving onto the next section.

Sanding the 1^st Base Coat

If your trowel technique is correct, the surface should be flat & even after the 1^st base coat, so you shouldn’t need to sand it.

However, if there are ridges in the surface, or the coverage across the area isn’t even, then we do recommend that you sand the 1^st base coat before moving on.

Wait until the surface is dry, this should take around 3 hours, but will depend on the conditions.

Use a 40-grit sanding disc to sand evenly across the area, removing any ridges, high spots & imperfections.

Ensure the surface is free from dust before applying the 2^nd base coat directly onto the surface (no additional primer is needed).
