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; a levelling 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.

Whilst Microcement is strong, it can only ever be as strong & stable as the substrate that it’s going onto. Which is why preparing surfaces correctly is so important. This kit can be used to fill cracks in concretes, screeds and self-levellers prior to microcementing.

Aquasell is thick a 2 part epoxy that can be poured into cracks to fill them and weld them together. As long as there is no further movement, the crack wont transfer through to the surface. Quartz sand is included for you to scatter on the wet Aquasell to ensure the microcement has a good grip on the surface.

To Repair cracks under 3mm wide
Use a 5” grinder to open up the crack (take care not to cut into any underfloor heating), hoover out any dust then mix Epoxy with Epoxy Hardener (Ratio 5:2) and pour into the crack. Leave to cure fully, this will take for at least 12 hours. It may need topping up depending on how deep the crack is.

To Repair cracks over 3mm wide
Use a 5” grinder to open up the crack and grind approx 100mm “stitches” horizontally across the length of the crack around 40mm apart (take care not to cut into any underfloor heating), hoover out any dust then insert steel helical stitching bars into the stitches. Mix Epoxy with Epoxy Hardener (Ratio 5:2) and pour into the crack. Leave to cure fully this will take for at least 12 hours. It may need topping up depending on how deep the crack is.

Mixer & Drill

Our custom made Microcement Mixer Head is ideal for mixing microcement.  It’s unique double helix design forces the product to the centre of the mix, thus reducing air in the mix.  This is important because to maintain its full performance and waterproof properties there must be no exposed areas in the microcement.

Silicone Carbide Sand Paper

Because Microcement is very strong, you need to use a strong, high quality sand paper that has been designed to be compatible with cement based products.  Our Silicone Carbide Sanding Discs have been rigourously tried and tested.  For most applications you’ll need: 40, 80, 120, 220 & 400 grits.  For large areas, you’ll really benefit from using an orbital sander & if you’re regularly completing large floors, it might be worth investing in a floor sander.

Clean Mixing Bucket, Measuring Jug & Weighing Scales

Most of the items in the kits have been weighed out for you.  But you may need to split larger tubs down into batches or weigh out sealers, hardeners etc to a reasonable degree of accuracy to get the ratios correct.

Applying Sealers / Primers

You’ll need a few Medium Pile Rollers & a Tray for applying the primers and sealers.  We find microfibre rollers work well for all the water-based products.  If you choose solvent sealer, you’ll need to use a roller suitable for solvents.

Use a Squeegee Trowel instead of rollers for applying High Performance Primer or Polyshield sealer.

To ensure the best price and freshest products, this kit is only available in 25m2 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.

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.
