    Step by step

    Step 1- Mixing

    Add the content of the bottle B (hardener) to component A (resin) in the bucket and mix with a low speed electric drill and stirrer until the mixture is completely free of lumps.

    Step 2 - Application as a tile adhesive

    Ceresit ULTRAEPOXY is applied directly from the mixing container and spread with a notch trowel in the same easy way as cementitious material.

    Step 3 - Application as a grout

    Apply the mixed compound with an epoxy grout float into the clean, dry joints. Make sure the joints are filled without any voids. Afterwards remove any excess material by skimming it diagonally off the tile surface with the grout float.

    Step 4 - Cleaning and finishing

    The grout work must be cleaned and finished while the product is still wet. Use a common wet sponge with any water temperature.

    Step 5 - Cleaning with EpoxyCleaN

    For the easy removal of any stains or residues left 24h after the use of Ceresit ULTRAEPOXY, use Ceresit CE 51 EpoxyClean as a special cleaner.
