CARRcrete BaseCoat Microcement is the perfect medium to start your microcement project off when you have a smooth floor surface. If your substrates are too rough we recommend using CoarseCoat or PRObase as a starting point.

Our microcement base coat is an awesome high tech formulation that includes every ingredient within the powder mix; no need for any liquid polymer. Simply mix with water and apply one to two coats to the floor before sanding smooth the next day and coating with either DeckCoat or FinishCoat finishes.

How To Prepare Substrate

  • Over CoarseCoat Layer: No need to prime, unless you prefer to. Ensure previous layer is dust and debris free before applying BaseCoat.
  • Non-porous substrates: Ensure the surface is dry, clean and free of bond breaking contaminants. Be sure to key the surface of any tile installations with a 30/40 grit diamond abrasive. Apply epoxy resin primer to surface and whilst tacky blind the resin fully with Chelford 30 sand (0.5mm). Be careful not to leave any bare patches of epoxy. Allow epoxy to dry and harden fully before removing excess loose sand.
  • Porous cementitious substrates: Ensure the concrete or screed surface is keyed with either coarse metal bond diamond tooling or a fine shot blast to create a textured surface. The surface must be dry, clean and free of bond breaking contaminants. Apply CARRcrete PROprime acrylic primer mixed 3 parts water to 1 part primer. Allow to dry fully before commencing with application.
  • Non-cementitious flow screeds: We do not recommend the use of this product over gypsum or calcium sulphate substrates, due to the unpredictable nature of these types of screed. Concrete surfaces are the most reliable to work with.

General Site Precautions

  • Site should be weather tight and with minimum temperature of 10’C
  • Through drafts may cause uneven drying to occur
  • Mask up any items that need protection; doors, windows, skirting, furniture etc
  • Work from the farthest corner back to a doorway
  • Large areas are better controlled by using multiple applicators

 

How To Mix

This product should only be mixed with cool clean water; warm water will reduce the cement set time to an uncontrollable rate. If colouring the product, always use CARRcrete colour packs to ensure compatibility.

  • Always agitate the product in its bucket before mixing 
  • Only mix what you can apply within 60 minutes
  • Use less than 280 grams of water for each 1 Kg of product required
  • Add required CARRcrete colour to water, rinse out container into mixing water
  • Mix at slow speed with electric paddle mixer
  • Gradually add the BaseCoat powder to the bucket whilst mixing
  • After 1-2 minutes, product should be lump free
  • Scrape down sides into the mix
  • Allow mixed product to slacken off for 1-2 minutes
  • Re-mix for 1 minute to ensure all is fully combined
How To Apply
  • Use a plasterers bucket scoop to place the mixed product on the surface. 
  • Prevent drops of micro cement from setting on substrate to prevent shadow spots
  • Spread the BaseCoat out with a semi-rigid stainless steel trowel, applying pressure to the surface to push the coat into the substrate beneath
  • You should feel the trowel pass over the grains of glass and quartz, this action determines the thickness of the layer
  • Apply 1-2 coats as required to create the look specified
  • You can apply subsequent coats as soon as the application can take your weight without causing damage. Alternatively allow to dry
  • Only sand between layers of BaseCoat if you need the smoothest possible finish
  • Allow to dry overnight and sand final layer before applying our DeckCoat or FinishCoat

Product Detail

Our BaseCoat Microcement is our usual starting point product. If the floor is smooth and flat, we opt for this as a base layer. When things are rough and out of specification, we turn to CoarseCoat or PRObase which is a hard self leveller before applying the BaseCoat.

This is a beautiful product that applies easily, evenly and is incredibly user friendly. We created the formulation to allow the product to have a greater degree of workability than many of the competition. Why make things difficult?

Having that extra degree of workability allows the base coat to be pressed into the substrate beneath to get a really good bite, plus the high grade powdered synthetic resins ensure that your micro cement installation is not going anywhere.

The powdered mix comes uncoloured which looks off white. You can of course colour the mix with our liquid pigment colour packs which produce a far superior tone that regular mineral pigments, these are ideal for quick and easy colour addition and mix super easy.

Every base layer needs to provide the strength for the deck/finish coats or the flooring will not last. To this end we purposely chose the hardest ingredients to include in this formulation. So out went the calcium carbonate and marble sands used by the competition and in came recycled glass and quartz to radically improve the performance of such a fine overlay system.

In MicroFloor BaseCoat we are using grains of glass and quartz with a maximum diameter of 0.5mm. Coarse enough to create texture, strong enough to provide a very durable coating suitable for high traffic areas.

Great rheology and working time were important attributes specifically detailed for this product in order to allow contractors more time when working in difficult areas or on multi-room projects. No need for mesh unless you need to cover cracks in the concrete flooring or floor screed.


MicroFloor BaseCoat is also suitable for a textured high strength non-slip decorative coating when correctly abraded.

If using as a finish coat ensure a protective layer of sealer such as water-based varnish like our MicroGuard and MicroSeal is applied as the final finish.

MicroFloor BaseCoat is supplied in 20 Kg recycle-able plastic buckets.
