Super Prefix 

High performance cementitious ceramic tile adhesive

Description

SUPER PREFIX is a high performance thixotropic mortar with a high bonding power, formulated on the base of cement, selected aggregates, synthetic resins and admixtures which improve its workability, water retention and adhesion. It is suitable for both interior and exterior ceramic tile placement with medium to high absorption degree as well as interior thin bed coatings.

SUPER PREFIX is classified as a cementitious adhesive C1TE according to UNE/EN 12004.

Application procedure

Substrate preparation: The substrate must be sound, clean and free from dust, superficial laitance, loose particles or any other material which would prevent the adhesion. The substrate humidity must be lower than 3%.

SUPER PREFIX can be applied to cementitious and concrete substrates and is particularly suitable for plywood. Do not apply on plaster (use PREFIX PLASTER instead) or substrates with under-floor heating. The surface must be leveled. Use a 2m ruler to minimize the level differences up to 5 mm.

Holes and existing voids must be repaired at least 24 hours before the application using any of the PREREPAR range products.

Product placement: Mix 25 kg of SUPER PREFIX with 7 liters of water to obtain a uniform mixture without lumps. The mixing speed must be slow, lower than 400rpm. Leave the mixture to rest for 5 minutes before the application. Apply simple bonding (on the substrate) and double bonding (substrate and pieces to be bonded) using a dented trowel. It is recommended to begin spreading the smooth part of the mortar first and then continue with the dented one. The percentage of the tile surface which gets in contact with the mortar must be higher than 80. Before the application, check that the mortar has not formed a superficial film which would prevent the adhesion. Should that be the case, trowel the surface once again. Place the pieces pressing hard to flatten the grooves.

Tiles larger than 900cm2 and those in a dovetail shape require a double bonding. Allow a waiting time of at least 24 hours before performing the joining. The distances between the joints should be 1.5 mm on walls and 5 mm on floors.

Tools cleaning: Tools and application equipment are washed with water immediately after use. If the product hardens, it can only be removed by mechanical means.

Recommended for

• Interior ceramic flooring with an absorption degree >3%.
• Interior ceramic flooring using IIB and III group tiles (water absorption >6%).
• Tiling on plywood.
• Swimming pools tiling.
