MasterFinish 380 Exposed Aggregate Retarder – 20L

Master Finish 380, previously known as MBT expose, is a water based chemical retarder to expose the aggregate in horizontal concrete surfaces. Master Finish 380 delays the set of the top layer of slurry to a controlled depth so it can be washed off once the concrete has set. The purple colouration of the liquid ensures even and adequate application.
