• How should I prepare my surface for microcement?

  There’s absolutely loads of information on preparing surfaces for microcement in our Surface Prep guides. The prep varies, depending on the substrate, but there are some generic rules that apply to all surfaces.

  Here are the golden rules to follow when preparing surfaces for Microcement.

  • Surfaces should be completely smooth – as if you were going to paint onto them.
  • Surfaces should be well consolidated, so that any chance of movement is eliminated.
  • Surfaces should have a minimum compressive strength of 16N/mm2

  Additional Important Rules:

  • Never Microcement directly onto natural timber or across cold joints/expansion joints.
  • Surfaces should be free from oil stains, dirt, dust and excessive laitance.
  • There must be no risk of water getting to the microcement during the install process.
  • Surfaces must be damp-proofed and edges siliconed so that no water can get to the Microcement from underneath at anytime.
  • Allow 3-4mm as the finished depth.

  For Kits Containing Micropool Only (Swimming Pools, Outdoor Surfaces & Steam Rooms):

  • Micropool can only be installed on a substrate with a minimum compressive strength of 25N/mm2 and a Tensile Strength of 1.5N/mm2.
  • Micropool is waterproof both above and below, so as long as substrate is less that 10% moisture, it can be applied.

• How do I get a good finish with Microcement?

  There are a few golden rules, that it’s really important to follow, if you want to get a good finish with microcement:

  It’s extremely important that you get the surface prep right.  You’re aiming for a clean, dry, completely flat surface, that’s free from movement.

  Familiarise yourself with the process in advance, don’t skip any steps and respect the drying times.

  Finally, 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.

  Thankfully, we’ve got all this covered, with our easy to follow, free online microcement training.

  From surface prep right through to aftercare, our online microcement training is packed full of step by step guidance, tips and tricks, to give you the knowledge and practical skills to tackle your project with confidence.

• Is microcement better than tiles?

  Microcement is an extremely versatile and hard-wearing material that is becoming increasingly popular in modern interior design. It’s a practical and visually stunning material that’s perfect for use in bathrooms and wet rooms.

  One of the main advantages of using microcement in a bathroom is its seamless finish. Unlike tiles, which have visible grout lines, microcement can be applied in continuously, creating a smooth and uniform surface. This not only looks great but also makes cleaning much easier, as there are no grout lines to trap dirt and bacteria.

• Is microcement expensive?

  Historically, microcement has been quite a niche product, with just a few installers charging high prices.

  However, we strongly believe that everyone should enjoy the benefits of microcement.  So, we’ve focused our efforts on making microcement more affordable and accessible to everyone.

  We’ve worked hard to make our microcement kits affordable, with kits starting from less than £30 per m2.

  And we’ve developed a whole load of free online training guides, including bespoke training courses for every customer.

• Is microcement waterproof?

  Not all microcements are completely waterproof, the natural minerals in the mix make them very porous. The microcements are sealed to make them waterproof. Which means that if the sealer gets scratched or there isn’t sufficient coverage of it, then water can get to the microcement and stain it.

  Thankfully, Cemher have developed a number of microcements that are 100% waterproof, even without sealers. These products have revolutionised the industry, making microcement a much more viable choice for DIYers and Professionals looking for extra reassurance.
