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; 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.
