The nature of concrete is porous hence it will absorb most liquids. If the liquid is oil, it will be hard to wash off and cause a dirty patch or unevenness on the flooring. This is important to the aesthetic of estates as visitors will see and comment to the owner and thereafter complaint will start to flow in as "design flaw". Although we know that it is not a design flaw but we are doing it out of goodwill to improve the relationship between the developer and the owners.

The above is the chemical formula for hardener
In short, when hardener comes into contact with concrete it will react with the limestone in the concrete to form a compound that had a higher hardness than limestone.
After studying the reactions and effects of hardener, i went further to outsource and found a contractor that is willing to do our carpark at a low rate and it will be done next week.
Three more weeks to end of internship and i already starting to miss this job. Had learnt so much more in just thirteen weeks and Mr Chan & Ms Lily had been so kind to me. Really hope Mr Chan will call me back after this internship.
