A1Creatives Concrete 7039 is a ready to use two-component system consisting of a mineral powder and a water-based resin. These bind in such a way that a very strong object is created with a Concrete look. A1Creatives is water-based, easy to use and does not contain solvents. A1Creatives is developed to be casted into a (silicone) mould as it will create a copy of the mould with all fine details.

A1Creatives Concrete consists of:

  • 100 grams of A1Creatives Concrete Liquid
  • 300 grams of A1Creatives Concrete Powder

The mixing ratio to create a mixture is 1 part Liquid and 3 parts Powder on weight. Make sure all components are present before starting to mix. Use a scale if needed.


  • Determine the amount of A1Creatives needed. The A1Creatives Concrete set is enough for approx 200 ml in volume. If needed you can combine several sets of A1Creatives Concrete together.
  • Shake the liquid well and pour 1 part liquid (on weight) into a cup. 
  • Put 3 parts of Powder (on weight) into the same cup.
  • Mix the Liquid and the Powder until all lumps have disappeared. Normally this will take between 30 and 60 seconds.
  • Pour about half of the mixture into the mould and shake or tap on the sides of the mould to remove any possible air entrapments. For more complex moulds we suggest to rotate the mould several time to create a layer of the mixture in the whole mould and to remove any possible air entrapments. An alternative is to brush a first layer of the mixture in the mould.
  • Fill the mould with the rest of the mixture.
  • Wait between 20 and 60 minutes to let the A1Creatives Concrete to cure. Use the leftover in the mixing cup to verify if the A1Creatives Concrete has cured. Extend the waiting time (for fragile objects with several hours) if needed.
  • Release the A1Creatives Concrete object from the mould. The object will at this stage look quite dark. It will take approx 24 hours to cure further and as a result will reach a lighter colour.
  • After placing the object onto a surface expect some moist to be released on the surface as the curing will continue for the next few hours.   

After treatment

  • You can sand or gently sandblast the A1Creatives Concrete object.
