Areas of Application

Indoor and outdoor grouting of ceramic tile and natural stone floors and walls. Also suitable for acid-resistant
bonding and rapid setting of ceramic tiles, stone materials, fibre-cement, concrete and any other building
material on all types of substrates normally used in construction.

Kerapoxy allows you to create floors, walls and worktops, etc. in compliance with the HACCP system and the requirements of EC Regulation No. 852/2004 regarding hygiene and foodstuffs.

Some application examples

  • Grouting floors and walls in the food industry (dairies, abattoirs, breweries, wine-cellars, conserved-food plants, etc.), shops and areas where hygiene is required (ice-cream shops, butchers, fish vendors, etc.).
  • Grouting industrial floors and walls (electrical industries, tanneries, battery rooms, paper-mills, etc.), where high mechanical resistance and resistance to acid attack is required.
  • Grouting swimming pools; particularly suitable for basins containing salt or thermal water.
  • Grouting tanks containing aggressive chemicals (purification plants, etc.).
  • Grouting ceramic tiles on laboratory benches, kitchen work surfaces, etc.
  • Acid-resistant bonding of tiles (used as an adhesive in compliance with class R2T specification according to EN 12004 standard).
  • Bonding marble doorsteps and windowsills.
  • Bonding tiles in plastic reinforced by fibre glass swimming pools.
  • Bonding special pieces of tiles.

Technical Specifications

Kerapoxy is a two-component, very low emission of volatile organic compounds, epoxy-resin-based product with silica sand and special components, with excellent resistance to acids and excellent cleanability.

The following features are obtained when used correctly:
• Excellent mechanical and chemical resistance, therefore excellent durability.
• A smooth final surface with low water absorption, therefore easy to clean; ensures hygiene.
• Easy workability and finishing.
• Becomes very hard and is highly resistant to heavy traffic.
• No shrinkage, therefore absence of cracks and fissures.
• Uniform colours that are resistant to ultra-violet rays and atmospheric agents.
• Excellent bonding.

Application Procedure

Preparing the joints
The joints must be dry, clean, free of dust and emptied at least 2/3 of the tile thickness.
The excess adhesive or mortar should be removed while still fresh.
Before grouting, make sure that the installation mortar or the adhesive has set and released most of its moisture.
Kerapoxy is not affected by the moisture on the surface; the joints should not be wet during work.

Preparing the mix
Pour all the hardener (component B), into a bucket containing component A and mix well until a smooth paste is obtained. For perfect mixing and avoiding overheating of the mixture, which could reduce working time, a low speed electric stirrer should be used.
Use the paste within 45 minutes from mixing.

Applying the grout
Spread Kerapoxy with the appropriate squezee, making sure the joints are completely filled. Use the same squezee, but on edge, to remove excess grout.

After grouting with Kerapoxy, floors and walls should be cleaned immediately, before the product dries.
Wet the surface thoroughly and emulsify with an abrasive pad for cleaning joints (such as Scotch-Brite® or MAPEI tile-joint cleaning kit), making sure not to wash-out the joints.
When cleaning walls, the cleaning pad should be fully soaked with water. The excess liquid can be removed with a hard cellulose sponge, and should be replaced when too full of resin. Use the same type of sponge for the final tooling of the grout.
It is very important that once the finishing process has ended, no traces of Kerapoxy are left behind on the tile surface because it will be very difficult to remove. It is therefore necessary to frequently rinse the sponge with clean water during the cleaning process.
When finishing large floor surface areas, use a rotary, disc-type power float with Scotch-Brite® abrasive pads, well saturated with water. All excess liquid can be removed with a rubber squeegee.

Application Procedure as an Adhesive

After mixing the two components as described above, spread the adhesive with a notched trowel. Apply the tile under firm pressure to ensure good contact.
After setting, bonding becomes extremely strong and resistant to chemical agents.

Set to Light Traffic At +20°C, floors are set to light foot traffic after 24 hours.

Ready for Use after 4 days. Surfaces can also undergo chemical attack after 4 days.

Cleaning Clean tools and containers with plenty of water before Kerapoxy hardens.
