PRi EPOXY

Suitable for resistant installation and grouting of floor and wall tiles and mosaic in interiors and exteriors with grout joints between 2 to 15 mm wide, such as:

• Floor and wall tiles in general
• Floor and wall tiles in bathrooms and showers
• Under floor heating
• Kitchen counter tops
• Terraces and balconies
• Dairy & food processing plant
• PRiBOND’SPRi EPOXY can be used for the grouting of ceramic tiles in environments submitted to direct contact with foods, like
• workbench of meats, dairy products of floor, basin for fish breeding, workbench in restaurant and bakeries.
• Suitable for applications where surfaces are exposed to aggressive chemical substances such as dairies, laboratories, pubs, food factories in general.
• Also recommended for grouting swimming pools and tanks containing thermal or brackish water.

• PRi EPOXY is easy to apply and easy to clean that lends the following advantages when used correctly:
• Extremely easy application and to clean even compared to normal cementitious sealants.
• Stable and uniform coloring for all types of tiles with exclusive colour effects.
• High mechanical strength & hardness.
• Very low water absorption.
• Total absence of cracking or crazing during hardening.
• Excellent chemical resistance.
• Excellent bonding.
• Uniform colors, resistant to weathering agents.
• Optimum hardness and ability to withstand heavy traffic.
• Stain free
• UV resistance

• Concrete
• Brick masonry
• Concrete masonry
• Cement mortar beds
• Gypsum wallboard
• Ceramic tile and stones
• Exterior glue plywood
• Non-water soluble cut-back adhesive
• Vinyl or other resilient tile
• Plastic laminate
• Cement backer board
• Steel
• Cement plaster
• Cement terrazzo

1. Before grouting check that tiles have been laid correctly and are anchored perfectly to the substrate Substrates must be perfectly dry.
2. Fill joints in accordance with the recommended waiting time indicated on the relative data sheet for the adhesive used.
3. For mortar substrates, wait at least 7/14 days depending on screed thickness, ambient weather conditions and on the level of absorption of the covering and the substrate.
4. Any water or moisture rising can cause vapour pressure to accumulate, which may in turn loosen the tiles on account of the complete in absorbency of the grout or of the tiles themselves
5. Joints must be free from any excess adhesive, even if already hardened, further more they must be of an even depth on the whole width of the tile covering, thereby ensuring maximum chemical resistance.
6. Any dust and flaky parts must be removed from joints by carefully cleaning them with electric dust extraction equipment.
7. Before grouting, check the clean ability of the tile covering, as porous or highly micro porous surfaces may make cleaning difficult. It is advisable to perform a preliminary test on tiles not to be laid or in a small, concealed area. In these cases we recommend treating the covering with specific protective products, being careful to avoid applying it to the joints.

1. PRi EPOXY is prepared by mixing together Parts A and B from the bottom upwards; using a low-rev (400/min.) helicoidal agitator, respect the preset ratio of 5: 1 of containers. Part A = 2 parts by weight & Part B = 1 Part by weight (two parts are pre batched in their respective containers) =
2. Pour Part B into the bucket containing Part A, being careful to mix the two parts uniformly until a smooth even coloured mixture is obtained. Only mix an amount of grout that can be used within 1 hour at +23 °C, 50% R.H.
3. The containers of PRi EPOXY must be stored at a temperature of +20°C for at least 2/3 days prior to use.

Higher temperatures will result in the mixture being too fluid and hardening too quickly, while lower temperatures will make the mixture harder to apply and will slow down setting, which is inhibited at temperatures of below +10 °C

1. PRi EPOXY must be applied evenly on the tile covering with a hard rubber spreader.
2. Seal the joints by completely grouting them, applying the filler diagonally to the tiles.
3. Remove most of the excess grout immediately using the spreader, leaving only a thin film on the tile.
4. Right after this start to clean up the tile surface.
5. On completion, to clean the tiles use a thick, hard and large-sized sponge damped in clean water to avoid removing grout from the joints. Use circular movements to soften the film of grout on the tiles and finish cleaning the joint surface. Specific highdispersion polymers ensure all grout residues are removed using only a small amount of water, which would otherwise impair the final chemical resistances.
6. Rinse frequently to ensure clean water is used at all times, using appropriate trays and grills with cleaning rollers, if necessary, replace the sponge or felt cleaning pad when saturated with grout
7. Finish cleaning up by dragging the sponge diagonally across the tiles to avoid going into the joints. 

• Do not use on joints less than 2 mm or more than 15 mm in width.
• Do not use on porous flooring for which more specific or alternative chemical resistances are required compared with those listed in the chemical resistances table.
• Do not use to fill elastic expansion or fractionizing joints or on substrates that are not fully dry and subject to moisture rising.

Always use protective gloves and eyewear both during mixing and during application avoid any contact with the eye. If in case happens do not rub, clean with plenty of fresh water immediately.
