Kiilto Pro Epoxy Tile grout

Tile grout

Before grouting, make sure that the tile adhesive is sufficiently hardened and the joints are clean. The tiling adhesive may have risen to a maximum of 1/3 of the joint’s depth.
When grouting, the temperature of the substrate, grout and tiles must be above +10 °C. The temperature strongly influences the consistence of the grout, working time and hardening. The warmer the mass, the easier it is to apply and the faster it is to cure. Floor heating should be switched off approximately 24 hours before tiling, and it can be switched back on around one week after.
We recommend mixing Kiilto Pro Epoxy Tile Grout in full containers. The correct mixing ratio is important to the hardening and properties of the grout. Mixing should be done mechanically, at slow speeds for at least three minutes. Scrape the edges of the mixing container from time to time while mixing. After mixing, the mass can be divided into heaps, so the reaction heat doesn’t reduce the working time. Do not add water or solvent to the mixture.
The grout is applied with a stiff epoxy rubber squeegee obliquely across the joints by vigorously pressing the joints to the full. The extra grout is removed as much as possible, thus reducing the material
residuals and need for washing.
Start cleaning as quickly as possible by first washing the tile surface with circular motions with a small amount of water using a coarse sponge, such as a scouring pad. This way, the joints get compacted and excess grout gets onto the surface of the tiles properly. Then remove the excess grout carefully with a softer sponge, regularly rinsing the sponge with clean water. The water should be changed frequently. Dry any excess water off the surface of the tiles with a sponge. Replace the sponge if its pores become saturated with grout.
Cleaning must be done carefully, because once hardened, Kiilto Pro Epoxy Tile Grout residue is difficult to clean off. For glazed tiles, leftover grout can be cleaned off within six hours by wiping with denatured ethanol (methylated spirits).
When using Kiilto Epoxy Cleaner for cleaning after tiling, it is important to thoroughly wash it off with clean water, as it will turn yellow over time, staining the surfaces of the joints and tiles.
Cleanability is heavily dependent on the type of tiles used, such as coarse tiles and porous tiles. If necessary, test the suitability for grouting and cleanability beforehand. When dealing with large areas, grouting and cleaning must be done in sections.
Tools can be washed with water, as long as it is done immediately.
Expansion joints, interfaces between differently moving building parts (such as corners and inlets), as well as joints between tiling and other surface materials, should be grouted with Kiilto Pro Sanitary Silicone or Kiilto Pro Silicone E.
Tiling can withstand light stress the following day. It will attain its final properties after seven days (at +20 °C). Cool conditions slow down the hardening.
When using the product for fixing tiles, the substrate must be firm, dry and clean. Put the mortar on the surface to be tiled (trowel 6x6x6 mm). The tiles are pressed tightly. The excess mortar residues are freshly removed with water.

Examples of grout consumption (not accounting for material loss):

Although Kiilto Pro Epoxy Tile Grout repels dirt very well and has very good cleanability, highly staining substances, such as tea or coffee, may leave stains on light-coloured joints. Thermally modified and exotic wood, such as thermally modified Monterey pine, may release chemicals into indoor air that can cause discolouration of the grout. Test the suitability if necessary. Chlorinated water can cause slight discolouration to white joints over time.
Due to the manufacturing technique of colour samples, there may be slight differences in colour between the samples and finished joints. The grout used to tile a unified space should all come from the same batch.
The information in this data sheet is based on our own research and practical knowledge. The technical values have been determined in standardised conditions. If the local conditions differ from these, they and the working methods will affect the values and the product’s functionality. The way the work is carried out also has a significant impact on the end result. Kiilto bears responsibility for ensuring that the product quality meets our quality system standards. However, the local conditions and working methods are beyond our control, and therefore we cannot be held responsible for the final result. To ensure proper product usage, the working instructions and method guide (if applicable) should be consulted.
