For professional installation of the agglomeration trend follow our simple recommendations.

  • General conditions

    With any agglomerate sheet or tile installation, you should begin by evaluating the site conditions, including temperature and humidity, substrate and waterproofing. For exterior installations, you should also consider the need for either partial or total covering. The substrate must be correctly aged; normal site practice suggested by adhesive manufacturers is to wait 28 days for the underlay and cement-based plasters to set, or even 90 days for concrete. With anhydrite-based substrates, allow a maximum of 0.5% residual humidity.

    It is also important to take into account the possible effects of temperature on adhesives and materials. At temperatures below 10°C, proper drying of the adhesive will be considerably slowed and could create problems for bonding over the long term. At temperatures over 35°C, it is advisable to carry out the installation at a time of day where there is less sun, generally in the morning or late afternoon. Also, you could shield the site from excessive sunlight during the hottest parts of the day, to prevent possible dehydration of the adhesive.

    It is equally necessary to consider the dehydrating effect of the wind, especially during the installation of exterior facades. In the case of swimming pools, it is possible that a leak test may be required to assess the behaviour of the underlying structure. Shower floors, whirlpools and jacuzzi tubs must always be waterproofed with special products. Before laying the agglomerate, all traces of dirt, grit and oil must be carefully eliminated and any loose parts and surface powder removed.

  • Technical instruments

    Before beginning, check that all the instruments are clean and rust-free.

    · Angle grinder with crown diamond, continuous cutting disc.
    · "Special" diamond disc for cutting agglomerate, diam. 110 mm.
    · Measuring tape and pencil.
    · String for marking main reference grid.
    · Mosaic pliers and cutter.
    · Set of various-sized trowels and floats. 

    · Toothed spreader, suitable for material/substance.

    · Rubber float for grouting and felt-backed float.
    · Tray with roller and sponge for cleaning. 

    · Trend agglomerate adhesive. 

    · Low speed drill with spiral mixer, so that adhesive properties remain consistent.

  • Laying agglomerations "Traditional System"

    Always make sure that the agglomerate sheets or tiles are positioned on a flat surface. Trace out the grid lines to match the number of sheets or tiles. Once the reference grid has been marked out, the adhesive is spread over the base. The adhesive is spread on the floor or wall, taking care that the teeth of the trowel are suitable. Then, with the smooth side of the trowel, spread glue on the back of the agglomerate, using the technique of double coating. Position the agglomerate with the utmost care, exerting a strong, uniform pressure to enable perfect adhesion to the substrate and release any excess glue. Check the contact between the agglomerate and the substrate, by removing one or more of the pieces already laid. Do not cover any expansion or structural joints, which must be filled with elastic material capable of absorbing movement.

  • Grouting and cleaning

    The surface of the agglomerate must be kept clean and any edge glue must be removed immediately after installation, before the adhesive dries. Then proceed with the grouting. First, using a sponge soaked in water, wipe the entire surface to eliminate all traces of adhesive. When grouting, the main technique is to use grout with a grain structure compatible with the size of the joint and to employ perfectly clean tools, to avoid defacing the agglomerate.

    Cleaning should begin before the grout begins to harden, preferably using Trend Clean. Prepare a container of Trend Clean diluted with warm water and, with the aid of a soft felt cloth, wipe in a circular motion to emulsify the excess grout and smooth the joints. Then, prepare another container of diluted Trend Clean and, using a sponge, remove any residual grout. Finally, use a sponge and clean water to remove any marks and polish the agglomerate to a bright finish. Any stubborn residues can be removed with Trend Special Clean and soft felt once the grout has set, rinsing the surface again when finished.

  • Care and maintenance

    The care and cleaning of agglomerate is very simple. We recommend regular cleaning using commonly-available neutral detergents, following the manufacturer’s on-pack instructions. Do not use wax, oil, hydrofluoric acid or phosphoric acid, or any products containing these ingredients. For special cleaning of limestone deposits, we suggest using a mild, slightly acidic solution and recommend testing this on a hidden area before proceeding generally. After cleaning, rinse immediately and thoroughly with clean water.

    For the walls of showers and bathrooms, we recommend using Trend Brilliant cleaner, which forms a protective film that prevents the formation of limescale and leaves a pleasant clean scent.
