A good surface retarder contributes to evenly washed out concrete by, as the word says, prevent the set of the top layer of the concrete. This to get an aggregate surface without etching or blasting.
What problems are solved when working with our retarders?
Working with the right type of retarder ensures that concrete surfaces are made suitable for decorative finishes or adhesion for second pours. It also prevents an uneven wash depth and makes it possible to better maintain planned time schedules for finishing concrete surfaces up to 72 hours.
