• Swimming pool tiling.
• Large surfaces with heavy traffic
• Suitable for tile over tile installations.
• Suitable for floor with underfloor heating.
• Suitable for swimming pool.
• Suitable for tiling over cementitious waterproofing surfaces.

Suitable Substrates

• Conventional cement-based substrates.
• All types of plasterboard or drywalls.
• Marble, granite, other natural stones, terrazzo, and all types of tile substrates, for both interior and exterior flooring, as well as interior cladding.
• Do not apply on top of paint.
• Substrates must be resistant, stable and sound. They must be clean, and free of dust, laitance, remains of release agents, and organic compounds. 
• All substrates must have a suitable flatness. If this is not the case, levelling can be performed up to 5 mm using the same adhesive, 48 hours prior to tile installation.
  • For levelling over 5 mm thickness use:
    • On floors: depending on the particular need, Paviland SL 10/ Paviland SL 10R, self levelling compounds, or a screed
    • On walls: mortars with an adequate tensile strength and with drying shrinkage already completed.
• In case extreme heat, hard wind or very absorbent susbstrate, it is recommended to moisten the substarte and wait for the water film to dissapear
• On exterior pavement installations, the substrate must have a slope equal to, or greater than 1%.
• Avoid application on gypsum, plaster, anhydrite or other substrates that may have a high sulphate content.
• Avoid contact with water with high sulphate content.
• All substrates must comply with the specifications in section 6.4 of the UNE 138002 standard.

Application Procedure

• Add water (23% - 25%) and mix manually or mechanically until a homogeneous and easy-to-work-with consistency is achieved.
• Let the mixture rest for 5 minutes and remix.
• Spread the mixed mortar on the substrate with a trowel to a maximum area of 2m².
• Comb the area with a notched trowel to adjust the thickness (see table).
• Place the tiles on the fresh adhesive, pressing and moving them until the ridges are fully flattened and the entire surface of the tile or stone adheres correctly. Periodically check the stickiness of the adhesive by lifting a tile, if you notice that skin has formed on the adhesive and the adhesive is no longer wet, remove the material and apply fresh product.
• Use the back-buttering installation method for exterior applications, when laying tiles with a side exceeding 45 cm, for commercial or industrial flooring, when underfloor heating is present, when levelling systems are utilized, or when the tile or stone has surface relief that may hinder proper adhesive contact.
• Respect the joints between the tiles as indicated in section 7.7 of the UNE 138002 standard. In interiors and swimming pools, the joint width should be ≥ (1.5 - 3) mm, and in exteriors, the joint width should be ≥ (3 - 5) mm, depending on the type of installation and the size of the tile being laid.
• Joints should be grouted after 24 hours on walls and after 48 hours on floors. Use the appropiate Morcemcolor product for grouting, depending on the type of installation.

NOTE: The shorter the time between spreading the adhesive and laying the tile, the better the results that will be obtained

Recommendations

• The longevity of the ceramic tile installation can only be ensured with proper planning. We therefore recommend consulting the national standards in force in each country, such as UNE 138002 in Spain. These standards outline specifications for material selection, proper planning, and installation, ensuring the achievement of the required levels of quality, performance, and durability.
• Application temperature range from 5ºC to 40ºC. Avoid application when there is risk of frost, rain, strong winds or direct sunlight.
• Under extreme weather conditions, drying occurs faster than normal, and less adhesive should spread before placing tiles.
• Maximum weight of tile or stone on walls : 60 Kg/m2
• Avoid application on gypsum plaster or paint.
• Do not use the spot bonding technique.
• Temperature, ventilation, substrate absorption, and coating materials can vary the workability and setting times of the adhesive.
• Respect the movements joints (structural, contraction, expansion, and perimeter) as indicated in section 7.8 of the UNE 138002 standard. These joints should be treated by placing prefabricated movement profiles or by filling them with elastic, deformable sealant.

Dimensioning and sizing of expansion joints

Dimensioning and sizing of perimeter joints

• Refrigerated rooms must stay turned off until the adhesive has cured, at least 7 days depending on environmental conditions.
• Swimming pools can be refilled 7 days after the adhesive has been applied. Tile adhesives do not replace waterproof membranes in swimming pools or other wet areas.
• On floors with underfloor heating, apply when the substrate is at room temperature. Underfloor radiant heated floors must be turned off at least 48 hours before installation and the ignition must be carried out gradually after at least 7 days from the installation.
• In applications on laminated plasterboard walls, ensure the substrate is securely fixed to prevent movement.
• When tiling over existing tile flooring, remove the poorly adhered pieces and fill the gaps with adhesive the day before the applying the new tiles. Ensure that the old ceramic is free of grease or wax residue. If necessary, grind the old surface until the tiles or stones lose their shine. If in doubt, perform a preliminary test to determine the suitability of the application.
• When installing façades, it is recommended to follow the local building codes or international reference stardards such as UNE 138002, BS 5385-2 or DIN 18515-1. Following these standards, Pidilite Puma recommends façade installations with mixed anchoring: adhesive and mechanical fastening, when any of the following conditions are met: formats greater than 2,400 cm2, a piece with one of the sides larger than 60 cm, a weight superior to 40 kg/m2, or an application above 3m high.
• When installing water sensitive or mesh reinforced stone or aggllomerate tile, contact the technical department to recommend the adhesive.
• Water-sensitive tiles that might stain or warp should be palced with a fast-setting adhesive, PEGOLAND FAST FLEX.
• For slate and thin porcelain slabs use PEGOLAND SUPERFLEX.
