CEM525 is extensively used for the grouting of tile joint widths greater than 1/8 inch (3 mm).
For added performance, EB550 SBR can be added to CEM525 to improve color uniformity and intensity, toughness and freeze-thaw durability. CEM525 should not be used in areas subjected to strong acids. CEM525 may be used with confidence in high traffic conditions such as:
- Factories and industrial applications
- Shopping mall and public utility services
- Industrial kitchens, dining halls and catering facilities
- Power plants and sub-stations
- Showers, toilets and bathrooms
- Decorative showrooms and domestic housing applications
- Hospitals and waiting rooms
- Swimming pools and fountains.
CEM525 may be mixed with EB550 SBR to improve color uniformity, intensity, toughness and freeze thaw durability.
- Do not grout if temperatures are expected to fall below 54F (12C) within 48 hours after application.
- Grouting may be performed after 48 hours from setting installation.
- CEM525 should not be used in areas subjected to severe exposure to strong acids.
Mixing: add CEM525 to water or EB550 SBR and mix to a thick consistency. Avoid adding too much mixing liquid which may cause color inconsistencies. To obtain uniform color, be consistent in the amounts of mixing liquids used. Mix at a low speed to avoid entraining excess air into the material. Let material slake for 10 minutes and remix prior to use. Do not add additional water to retemper material.
Application: for unglazed tile, dampen the surface prior to grouting, but do not leave water in the joint spaces. Using an appropriate grouting float, diagonally press material into spaces with pressure to insure complete filling of the joint. Remove excess material with edge of the float. Once the grout has acquired an initial set, smooth the joints and remove the grout haze from the tile with a slightly dampened soft cloth. Protect grout surface with building paper for several days after installation to protect the grout from dirt or stains. To inhibit shrinkage, cracking and color inconsistencies during dry or hot conditions, it is especially important to cover the grout joints with building paper in order to maintain a damp cure. If necessary, a final cleaning may be performed with soap and water to remove any residual grout haze from the tile surface. A mild solution of grout cleaner, suitable for tile installations, may also be used to remove well-adhered grout haze from tile. Refer to manufacturer’s recommendations for use of cleaners and always apply a test sample in a hidden area to evaluate performance prior to entire application. Sealers may be applied after 28 days from application.
Coverage: varies depending upon the size of the tile and the width of the joint.
Cleaning: CEM525 should be removed and cleaned from equipment and tools with water immediately after use.
Store out of direct sunlight. Store in cool, dry storage facilities. Shelf life up to 12 months when stored in original bags in cool, dry storage places.
CEM525 is non-flammable and non-toxic in nature, avoid contact with eyes and skin as it may cause irritation due to its alkaline nature. Splashes of CEM520 should be washed off immediately with clean water. Wear necessary gloves and dust mask.
