Mapei Technical Services were on site for the entire duration of the work so that the client and contractor could be sure the proposed products and solutions were applied correctly.
Mapei products were used to install the decking and the rubber flooring on the external bridges, tiles in the swimming pool on the main bridge, the kitchen coverings and the bathrooms for the cabins. The total surface area installed amounted to around 2,000 m2.
As far as the external areas were concerned, the metal surfaces were treated with PRIMER MF two-component, epoxy resin-based, low viscosity primer. This product is solvent-free and non-flammable. The surface of the primer was broadcast with QUARTZ 1.2 ME to guarantee perfect adhesion of the smoothing and levelling compound. Then, in order to form a perfectly flat surface, the substrates were levelled with ULTRAPLAN FIBER KIT ultra rapid-hardening, self-levelling smoothing compound (manufactured and distributed exclusively in the UAE), which had been recommended to the client for its high level of resistance to foot traffic.
Once the surfaces had been levelled off, a coat of KERALASTIC two-component, solvent and water-free polyurethane adhesive was applied on the surface to make it more elastic and waterproof.
At this point the decking flooring was bonded in place with KERALASTIC T two-component polyurethane adhesive while for the rubber coating ADESILEX G19 epoxy-polyurethane adhesive has been chosen. The grout lines were filled with ULTRACOLOR PLUS high-performance, anti-efflorescence, rapid-setting and drying polymer-modified mortar with water-repellent DropEffect® and anti-mould BioBlock® technology.
Mapei products were also chosen to install ceramic and marble in the swimming pool on the main bridge. White ADESILEX P10 non-slip, improved cementitious adhesive was used to bond the tiles. This product is particularly suitable for bonding glass mosaics, ceramic and marble. To improve its performance characteristics and deformability to the requirements of class S1 (deformable adhesive) according to EN 12004 standards, 50% of the mixing water for the ADESILEX P10 adhesive was replaced with ISOLASTIC elasticising latex.
The grout lines were filled with KERAPOXY and the separation joints were sealed with MAPESIL AC pure acetic solvent-free, silicone sealant. The wide range of 34 colours available for this particular sealant met the requirements of the client, enabling a finish to be obtained which was well up to the standards required for the yacht.
PRESTIGIOUS FINISHES FOR THE INTERNAL SURFACES
The internal floors in the kitchen and the bathrooms for the cabins were prepared using the same method as for the external surfaces, by applying PRIMER MF, QUARTZ 1.2 ME and ULTRAPLAN FIBER KIT in the same order. The tiles on these surfaces, on the other hand, were bonded with KERAFLEX MAXI S1, a non-slip adhesive with a good degree of deformability which, thanks to the use of innovative Low Dust technology, considerably reduces the amount of dust given off when mixing the product. ULTRACOLOR PLUS was used to grout the joints. KERAFLEX MAXI S1 was also used to bond the tiles in the bathrooms and, in this case, KERAPOXY anti-acid epoxy mortar was the preferred choice to fill the grout lines.
