We often get asked what the best way of creating a “polished concrete” look with microcement, so we thought we’d make a kit with all the right products for achieving this popular effect.
This kit contains everything that you’ll need to complete a microcement install with a finish that is very similar to “polished concrete”.
To get the “polished” look, you’ll need to close in the pours from the previous coat with increasingly fine coats. This isn’t possible with a lot of microcements as the “fine” option is rarely strong enough for floors.
Which is why we’ve chosen MicroLevel for this Kit. The microcements contain densifiers so making them super strong, meaning even the fine option is suitable for use on floors.
The kit includes fibre glass mesh for strength, a choice of primers – one for absorbent surfaces and one for non-absorbent surfaces. Enough MicroDur Thick Base for you to complete 2 base coats.
MicroDur Thick Base is ideal as it’s one of our strongest, most durable microcements, it’s also easy to mix and apply with a long working time of up to 3 hours.
MicroDur is a mono-component microcement, which is mixed with water – this makes it stronger than resin-based bi-component microcements as the cement actually reacts with the water to form concrete. MicroDur contains powdered additives give it flexibility, strength and prevent cracking.
Once the MicroDur Thick Base is applied and you’ve given it time to dry, you’ll be applying the MicroLevel Medium. MicroLevel Medium has a slightly shorter working time than MicroDur, so it needs to be mixed in smaller batches, ideally no more than 10kg at a time. It contains a medium sized aggregate, this makes it smoother whilst retaining a superb compressive strength.
Once a coat of MicroLevel Medium is complete and the microcement has had time to dry, you’ll be applying a very thin grout coat of MicroLevel Fine. This will fill in all the pours and give you a smooth, polished look.
Once dry & gently sanded, you can seal it with Cemher’s premium water resistant, acrylic based pre-sealer, HydroPrimer. When applied correctly, HydroPrimer will deeply penetrate the microcement giving it an almost impenetrable resistance to moisture.
This will be consolidated with 2 hard, durable, opaque coats of AquaMax Extreme – this is our highest performing water-based, 2 part polyurethane sealer which can be rolled onto the surface with a microfibre roller.
All the colours are accurately weighed out for you so all you have to do is add them to the mix.

This refers to the surface or “substrate” that you will be applying the microcement to. Absorbent substrates include plaster, concrete, screeds, cement board and composite timbers. Non-Absorbent substrates include tiles, marble, metals and plastics.
We will supply you a different primer depending on the surface, namely Primer TAC for non-absorbent surfaces and Primer 100 for absorbent ones.
If you have a mixture of absorbent and non-absorbent substrates, then you can either let us know at the checkout and we can provide a different primer for each 10m2 or purchase an additional primer. Consumption rate is 1l per 10m2.
With 40 colours to choose from, it’s worth taking some time to make sure you have chosen the right colour.
We’ve tried to represent the colour as accurately as possible by providing images of each colour and an image of it in situ. You can view large versions of the swatches and images on Colour Options. Please be aware, however that colours can vary quite dramatically from screen to screen. So to make sure you’ve found the right colour for your project, we’d highly recommend that you buy a Colour Swatch or Swatch Book so that you can see it for yourself.
It’s also a good idea to take it into the room and place it against the wall and floor to see how the colour is affected by the light in the room. As with paints, different lighting can give a very different impression of the colour.
All the products are made up in batches of 10m2. So we can give you a different colour for each 10m2 but we won’t be able to break them down any further than that. If you would more than 1 colour and can split them into 10m2, then just select one of the colours and leave us a note at the checkout to tell us which other colour you would like and how many m2 of each.
If you require more than one colour but not in 10m2 batches, then you can choose one of the colours for your kit and buy the second colour separately. You will then need to weigh the colours out for yourself – you can work out how much colour to weigh for each 1kg of product by dividing the no. grams colour per 10kg by 10. The no. grams per 10kg will be shown on the colour pigment bottle. It’s important that colours are weighed accurately using scales that go down to 0.01g, failure to do so will result in colour variation across batches.
If you need more than 40m2, then please get in touch and we will work out the cheapest price for you.
All our products are supplied in multiples of 10, so you’ll need to round up to the nearest 10m2. Unfortunately we can’t supply kits in different quantities as it would mean opening the tubs which would reduce their shelf life.
Microcement is a cement-based render that can be applied to a wide range of surfaces to give a seamless, durable finish with an appearance that is similar to polished concrete. It is applied in four very thin coats giving a finished depth of just 3-4mm – and can be done by homeowners with the help of a DIY kit and some basic guidance.
It can be used to completely transform the look of existing surfaces (including plaster board, composite timber and painted walls) or as an alternative to tiles and other finishes across floors, walls, wet rooms or worktops. Because microcement is applied to surfaces in situ, it can be applied seamlessly without the need for joins or grout lines – making it easier to keep clean.
You’ll be using a trowel to apply 4 coats of microcement one after the other onto your surface. The surface will need priming and meshing beforehand and sealing once it has had time to dry.

If you are completing a DIY project in your own home then we would suggest you start with one of the DIY Kits. The DIY Kits aren’t quite as strong as the Professionals Kits but they’re pre-mixed and waterproof so easy to work with & apply.
Tradespeople, including plasterers, who haven’t used microcement before will need to spend some time familiarising themselves with the processes and techniques to achieve professional results. And we would recommend starting with the DIY kits.
There are two things that you/they will need to bear in mind to complete a microcement install successfully:
1. Process – familiarise yourself with the process in advance, don’t skip any steps and respect the drying times.
2. Technique – use the grain as a level, go as tight as you can with each coat, complete an area using small random trowel movements, then blend it into the previous section, removing any excess as you do so.
The process is very similar whichever kit you choose, however they each contain products with small differences that make them more suitable for the end use. The Professionals Kit for Floors has a thicker base coat and a hard sealer where the wall kit is more focused on getting a good visual texture and smooth finish for example.
You’ll need to leave it 48 hours once the last sealer has been applied to give it time to harden. And then ensure light use only for the first 14 days.
Like all cementitious products, microcement takes 28 days to fully harden. Any heavy work is not recommended, but if it does take place then we recommend that you cover the microcement with a breathable material or only cover down whilst working and lift the protection off for the majority of the time.
You can microcement onto almost any surface as long as it is smooth and free from movement. You may need to prepare the surface for microcement before you start.
Some of the more common surfaces that you can microcement onto, are listed here:
Cement Board, Composite Timber Boards, Plaster Boards, Painted Walls, Plastered Walls, Concretes, Screeds, Self Leveller, Tiles, Plastics, Metals, Marble.
A well consolidated concrete or screed floor is probably the best surface to be microcementing onto. Make sure it has been give plenty of time to cure fully before applying microcement.
Yes, all the products in this kit are fire retardant, so can be used on fireplaces and around log burning stoves. However direct contact with open flames should be avoided.
This isn’t the best kit for using in wet rooms, whilst some professional installers do choose to use it in wet areas, it will be completely dependent on the sealer so generally we would recommend the Professionals Microcement Kit for Wet Rooms instead, which contains a waterproof microcement.
Microcement surfaces can be cleaned with any pH neutral cleaning products.
Do not clean microcement surfaces with aggressive or descaling products, such as those which contain chlorine, bleach and ammonia as they can damage the sealers.
Use Cemher Floor Protect every 2 -3 months to protect you microcement and to help build up the sealers.
