Choose Finish

This refers to the sheen of the sealer coat.  Choose the one you prefer. And don't worry they all perform equally well.

Matt

Flat matt with the lowest level of sheen. Great for achieving a natural effect across walls & wet rooms.

Satin

A light sheen to finish off an installation. We love using satin on big open floors, for a framed yet natural finish.

Gloss

The highest level of sheen, another great one for floors or more opulent interior schemes.

Choose Primer

You'll need to choose the right primer for the surface you're going on to. If split water would soak into the surface it's Absorbent, if not choose Non-Absorbent. For floors with joins or cracks, High Performance is best.

Choose Sealer

Choose between some of the highest quality microcement sealers on the market: Water based, AquaMax Extreme, Solvent based, MaxiPur and the incredible new Polyshield.

Water Based

Water based, AquaMax Extreme, is a very good sealer for microcement. Extremely hard and has a high resistance to scratches. Use a medium pile roller to ensure good coverage. Relatively odourless.

Solvent Based

Because it’s solvent based, MaxiPur will naturally repel water, giving it a slightly higher level of stain resistance, it’s also slightly thicker than AquaMax Extreme which makes it easier to get good coverage. Good ventilation and protective masks are essential for application as it emits a strong chemical odour whilst wet.

Quality Assured

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.

Ask a Question

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.

The products in this kit were originally designed for swimming pools.  They can be fully submersed in water on both sides and be completely unaffected. This is particularly useful when microcement needs to be applied to eternal patios, slabs and retaining walls that have not been damp proofed.

Both the base coat and the top coat are incredibly strong and durable.  Making them suitable for use on car driveways.

This kit contains everything that you’ll need to complete a long-lasting, durable microcement exterior.

You’ll notice that this kit doesn’t contain primer and mesh.  This is because MicroRock Base has incredibly good adhesion so can be applied directly to the substrate.  And it’s best not to inhibit it’s adhesion by including mesh in the mix.  However we would also recommend using fibre glass mesh for bridging joins.

Because Microrock is incredibly strong, it requires a substrate that is sufficient to hold it.  Surfaces must have a compressive strength of at least 25N/mm2 and a tensile strength of 1.5N/mm2.

The base coats is MicroRock Base which is our strongest base coat, the MicroRock Base is pre-mixed in a tub and comes with a hardener to be added at the point of use.  Once mixed it has around 45 minutes – 1 hour working time. MicroRock is a 2 part epoxy based microcement. It is incredibly strong, has excellent adhesion, and will not crack.

Once the MicroRock Base is applied and you’ve given it time to dry, you’ll be applying the MicroRock Medium.  MicroRock Medium is available in either a Stucco Effect or Continuous Effect – so you can be sure you’ll get the look that you want. Either way, the MicroRock Medium is strong and smooth, it’s just the “visual texture” that will vary depending on your choice.

MicroRock is unbelievably hard and 100% waterproof.  Uniquely for an epoxy based Microcement it retains a very organic, mineral finish when dry.

Once 2 coats of MicroRock Medium have been applied, you’ll be sealing it one of Cemher’s advanced sealer systems.

Training & Installation Guide

Once you’ve purchased the kit, you receive a thorough training and installation guide which includes a step by step guide to the complete installation of this kit.

Pre-Mixed Colours

Choose from 56 beautiful new colours, including 18 which are only available from Relentless Microcement.

Each of the colours have been scientifically formulated to counter tonal variations across the microcement product ranges. Microcement contains natural minerals so colours may still vary slightly between batches.

Consumption per 10m2
MicroRock Base 20kg
MicroRock Medium 10kg
MicroRock HARDENER 3l

Each of the sealer systems has been designed to exceed expectations, but each has unique features with different appeal depending on your preferences and requirements.  Here’s an overview of the process, pros & cons for each sealer system to help you decide which one is right for you.

Water Based Sealer System

You’ll be applying a hard, durable, opaque coat 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.

Because it’s fire rated, AquaMax Extreme is the one to choose near firepits and barbeques.

Solvent Based Sealer System

Again, you’ll start the sealing process with a coat of water-based AquaMax Dur, a 2 part polyurethane sealer which can be easily rolled on with a microfibre roller.  This provides the 1st coat of sealer protection and prepares the surface for the MaxiPur.

Because it’s solvent based, MaxiPur will naturally repel water, giving it a slightly higher level of stain resistance, it’s also slightly thicker than AquaMax Extreme which makes it easier to get good coverage.  Good ventilation and protective masks are essential during the application of MaxiPur as it emits a strong chemical odour whilst wet.

MaxiPur is not recommended for use near an open flame.

Both continuous & stucco effect are smooth to touch but the “stucco” will have more visual texture and some colour variation, sometimes described as a “cloudy” texture, whereas the continuous effect has a more uniform, gentle texture. Coarse effect contains a thicker grain so is slightly coarse touch.

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. Click below to view the step by step which shows the breakdown of tasks:

Step by Step Installation Guide

Once you’ve purchased the kit, you’ll receive access to a thorough online training and installation guide which includes a more detailed step by step guide to the complete installation of this kit.

If you are completing a DIY project in your own home then this kit is ideal. 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 DIY Kit you choose, however they each contain products with small differences that make them more suitable for the end use. The DIY 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.

Because Microrock is incredibly strong, it requires a substrate that is sufficient to hold it.  Surfaces must have a compressive strength of at least 25N/mm2 and a tensile strength of 1.5N/mm2.

Concrete and cement board are most likely to meet this criteria, but we’d recommend that you get datasheets from the manufacturers of any substrates that you are planning on applying MicroRock to be sure.

Concrete or cement boards are best.

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

Microcement Installation Guide  for External Surfaces

Yes, this is the best kit to use on external surfaces.

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.
