Retarder 20L (AuSeal)

Concrete retarder (AuSeal) is the tool for an exposed aggregate finish. Applied to the fresh surface or to the form, it slows the set of the top layer of cement paste so it can be washed back the next day to reveal the stone underneath.

Timing and wash-off make the finish, so follow the coverage and timing directions for the look you want. It is used on feature driveways, paths and patios. Supplied in a 20 litre drum.
