01. Product preparation
Ceresit CE 79 and CE 89 consists of two components supplied in one container. Add the hardener (component B-catalyst) to the resin (component A) and mix with a low speed electric drill and stirrer until the mixture is free of lumps. Hand mixing is not recommended. Make sure that all the paste is catalyzed.
The two parts are pre-batched to avoid this way any risk of mixing errors. Do not add water or solvents to improve workability.
Scrape the sides and bottom of the container to make sure all the paste is catalyzed.
02. Grout application
The ideal temperature for application is between +18 and +23 °C – the product is an easily workable smooth paste, with a pot life time, working and correction time of 60 min. At temperatures between +8 and +12°C, the product is very dense, difficult to apply and the hardening time is lengthened.
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.
03. Cleaning and finishing
The The grout work must be cleaned and finished while the product is still wet. Use a common wet sponge with any water temperature.
For the easy removal of any stains or residues left 24h after grouting, use Ceresit CE 51 EpoxyClean. Some kinds of tiles (e.g. polished porcelain tile) and natural stone have rough, microporous surfaces, making them susceptible to staining and very difficult to clean. In this case preliminary test application should be performed.
