Eucobar is designed to be used as an evaporation retardant on concrete surfaces of all types. When sprayed over fresh concrete, Eucobar forms a monomolecular film that prevents rapid moisture loss from the concrete surface.
Euclid Eucobar is an evaporation retardant and finishing aid designed to reduce rapid moisture loss from fresh concrete surfaces during placement and finishing. When sprayed over fresh concrete, it forms a monomolecular film that helps hold surface moisture, reduce crusting, and minimize the risk of plastic shrinkage cracking. Eucobar is especially useful in direct sun, wind, high temperatures, or low relative humidity where evaporation rates can rise quickly.

What is Euclid Eucobar used for?
It is used as an evaporation retardant and finishing aid on fresh concrete to help reduce moisture loss, crusting, and plastic shrinkage cracking during placement and finishing.
How is Eucobar mixed?
Eucobar is supplied as a concentrate and must be diluted at a 9:1 ratio of water to Eucobar before application.
When should Eucobar be applied?
It should be sprayed over fresh concrete as soon as possible after floating. In extreme drying conditions, additional applications may be used as needed.
Can Eucobar be used as a curing compound?
No. The manufacturer specifically states that it should not be used as a curing compound.
Does Eucobar affect the color of concrete?
No. It is a pink liquid concentrate, but its use will not affect the final color of the concrete.
What should be avoided when using Eucobar?
Do not use it as a surface retarder for exposed aggregate concrete, do not apply it as a final finishing aid, do not immediately work it into the surface, and do not allow it to freeze.
