With our extensive installation experience, which we’re happy to share and Cemher’s extensive product range, you’ll be a step ahead when it comes to taking on microcement jobs from this day forward.

Cemher’s parent company, Kilnher, have a long history of producing microcement products, which they supply as white label to almost all of the familiar microcement brands on the market. Their familiarity with the competition puts them in a unique position to develop a game-changing range of microcements.

Refreshingly, Cemher don’t adhere to the “one size fits all” approach that many of the microcement brands have adopted. Instead they have developed a number of different products to suit specific scenarios. These include; microcement for large floors and high traffic areas, the strongest microcement in the world, MicroRock, waterproof microcements for wet areas and at long last, a sealer that you can be confident in using to meet the specific demands of worktops.

We know that there’s a lot to take in at first – microcement itself is quite an involved process and the Cemher range is larger than most.  

So don’t muddle through on your own.  Whether you need an estimate, technical advice, help choosing products, or just want to touch base, we are ready and waiting for your call.

This revolutionary new kit allows professional microcement installers to create an incredibly strong microcement floor without compromising on finish.

Contains all the products that you will need to complete an 40m2 microcement floor to a high performance spec.

By sandwiching our tried and tested hero product, MicroDur Medium, between a combination of incredibly strong products, the ever-popular effect is preserved against anything that life might throw at it from both above and below the surface.

This kit does require some professional knowledge and equipment so is recommended for experi-enced microcement installers only, we are on hand to offer help, advice and training to anyone hop-ing to transition to using high performance kits.

The process begins with the application of our High Performance Fibre Glass Mesh and Aquasell.

Aquasell will bond the Fibre Glass Mesh for Thick Base to your substrate adding strength to the substrate and creating a strong, impenetrable base for your microcement.

It will also ensure a uniform drying rate across the microcement surface and block stains in the sub-floor transferring through to you microcement.

It is particularly good at stopping small cracks in concrete floors and joins between boards being transferred through from the substrate to the microcement. The chance of move-ment must still be eliminated in advance.

Quartz sand is included in the kit. This will be used to “sand blind” the epoxy in order to give it a key.

Base coats are completed in MicroDur Thick Base is ideal as it’s one of our strongest, most dura-ble 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 Mi-croDur Medium. MicroDur Medium has similar attributes to MicroDur Thick Base, with a working time of around 3 hours, yet it contains a medium sized aggregate, this makes it smoother whilst re-taining a superb compressive strength. Plus, you’ll find it’s extremely resilient, you can take your time as you move across large floor area, blending as you go.

Once 2 coats of MicroDur Medium are complete and the microcement has had time to dry, you’ll be sealing it with Cemher’s premium water resistant, acrylic based pre-sealer, HydroPrimer. When ap-plied correctly, HydroPrimer will deeply penetrate the microcement giving it an almost impenetra-ble resistance to moisture.

This will be consolidated with 2 incredibly hard, durable, opaque coats of MaxiPur – this is our high-est performing solvent-based, 2 part polyurethane sealer which can be rolled onto the surface with a roller suitable for use with solvents. The thick, oily consistency of MaxiPur helps to ensure that sufficient product is installed on the surface, it dries incredibly hard and repells water and other stains extremely effectively.

All the colours are accurately weighed out for you so all you have to do is add them to the mix.

You will find a step by step which is specific to this kit and an installation guide in your delivery.

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.

To ensure the best price and freshest products, the High Performance Kits are only available in 40m2 batches – we can’t offer different amounts at present.  However you can by all the products individually so get in touch to discuss your specific needs.

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.

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.

We wouldn’t normally recommend that you use the High Performance Kits without some experience or training.  Please get in touch to discuss your specific requirements and we will advise how we can help you transition into using these products.

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.

Our installation guide includes a detailed explanation on how to prepare a wide range of common surfaces for microcement:

Microcement Installation Guide for High Performance Floors

This isn’t the best kit for using near to heat. If you are hoping to microcement onto a fireplace or around a log-burning stove, choose the professionals kit for walls instead.

This isn’t the best kit for using in wet rooms, whilst some professional installers do choose to use it in wet areas, 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.
