Product Properties

• Plastically flexible laying mortar, the medium bed mortar is only distributed with an adequately large notched trowel or medium bed trowel
• Deformation capable, compensates for temperature fluctuations and substrate stresses
• Adheres without priming or base coat on concrete, cement screed, and cement plaster
• Effective crystalline water binding, making it particularly suitable for large-format ceramic tiles
• Low shrinkage, even with large mortar layer thicknesses up to 4 cm, no shrinkage stresses occur between PCI Carrament and natural stone tiles
• Durably water-resistant and frost-proof, suitable for interior and exterior use on walls and floors
• Fast setting, reduces the absorption of moisture during installation, preventing efflorescence
• Quickly hardening, walkable and groutable after approximately 6 hours, fully loadable after about 1 day
• In white, no show-through of the adhesive bed with white marble when installed using the combined buttering-floating method
• PCI Carrament meets classification C2F according to DIN EN 12004
• EMICODE EC 1 PLUS R

Application Area

• For interior and exterior use
• For walls and floors
• For laying natural stone tiles, including sheet material
• For large-format porcelain stoneware tiles
• For leveling uneven substrates prior to installation
• PCI Carrament grey also for laying sewer pipe bricks in wastewater structures
• For stairs and house sills in residential areas on electric underfloor heating, screeds, balconies, and terraces in halls, rooms, and on industrial building floors
• In institutions, service, and administrative buildings

Substrate Preparation

• Minimum substrate age: PCI Novoment Z1 or PCI Novoment M1plus screed 24 hours
• PCI Novoment Z3 or PCI Novoment M3plus screed 3 days
• Cement screed 28 days
• Concrete 3 months

The substrate must be dry, dust-free, and load-bearing. Highly absorbent cement substrates should be primed with PCI Gisogrund 1 diluted with water. For sanded anhydrite or gypsum, liquid screeds, and cast asphalt screeds indoors, prime with undiluted PCI Gisogrund. For time-sensitive work, cement and gypsum-based substrates should be primed with PCI Gisogrund Rapid. Allow primer to dry. Screeds must not exceed 4% residual moisture content, anhydrite screeds not more than 0.5%.

Application of PCI Carrament

Pour the mixing water into a clean working container. Then add PCI Carrament and mix with a suitable stirring or mixing tool attached to a drill until a homogeneous, lump-free mortar is achieved. After a reaging time of approximately 3 minutes, briefly remix again.

Installing Natural Stone Tiles

Medium bed method: Apply PCI Carrament section-wise to the substrate, draw a contact layer. Distribute as much mortar as can be covered with natural stone within the open time using a medium bed trowel or a suitable notched trowel to achieve a fully bedded installation. Check the open time with a finger test. Lay tiles with a slight sliding movement to achieve a fully filled bedding.

Adhesive method: PCI Carrament can also be used for setting large-format natural stone tiles on walls, such as stairs, risers, or sills. Apply PCI Carrament in the desired thickness to both the substrate and the back of the tiles using a medium bed trowel or spatula. Position the natural stone tile, align, and possibly wedge. Ensure only as much mortar is applied as can be covered with tiles within the open time. Check the open time with a finger test. Applying PCI Carrament to the back of the tiles prevents show-through of the adhesive joints and allows for a largely hollow-space-free installation.

Grouting

For joint widths from 1 to 8 mm

Special Cases

• Plastic jointing for polished natural stones: PCI Flexfug, 2 to 10 mm joint width, exception: sand grey tone 3 to 15 mm
• PCI Rapidfug, 1 to 10 mm joint width

For non-sensitive natural stones, consulting PCI is recommended. Other PCI joint mortars may also be used, such as:

• From 2 to 8 mm joint width: PCI FT Fugengrau, PCI FT Fugenweiß
• Elastomeric joints: corner joints, floor-wall, wall-wall, wall-ceiling, and connection joints, installation parts, tile coverings, wood coverings, elastic with PCI Carraferm
