FLOOR AND WALL TILES – CERAMIC

1. PROPER PREPARATION OF SURFACE

The wall must be firm, levelled, dry and clean. Uneven surfaces greater than 2 mm must be levelled with specific products. All cracks and imperfections should be repaired, so that the wall is completely smooth. The moisture content of the surface must be under 2%.

2. INSTALLATION MATERIAL

For a correct installation, several factors must be taken into account: Material kind of the wall to be tiled (synthetic pannels, plaster, wood, etc.), wall stability, environmental conditions, kind of surface to be covered , speed of carrying the work, etc. All the above parameters determine the choice of the adhesive kind.

All the adhesive materials recommended by DUNE have been previously tested in our facilities, in controlled environmental conditions and on rigid brick and/or concrete walls. Under different conditions from the above mentioned, it is recommended to test firstly and if in doubt, please contact DUNE or the adhesive distributor.

White and Red body wall tile: C1 concrete glue. (Consult adhesives table).
Stoneware and porcelain tile: C2 concrete glue. (Consult adhesives table).

DUNE always recommends to test first the material with minimum two pieces before placing all the material.

3. INSTALLATION

We recommend starting the installation from the floor to the ceiling, continue in phase to allow the adhesive the necessary time to get dry. Extend a thin layer of adhesive on to the surface where the piece will be installed (3mm approx.) Then, use a notched trowel no. 3 to make incisions into the adhesive layer. Place the piece while the adhesive is still soft and before a dry layer of film forms on the adhesive surface. To install 30×60 pieces or similar, extend a thin layer of adhesive on the surface where the piece will be installed (vertically) and another layer on the back of the piece itself, in the opposite sense (horizontally). Then, use also a notched trowel no. 3 and make the incisions into both the adhesive layer of the wall and in the opposite sense in the piece. Do not use dot setting or dab the adhesive during installation.
Once the piece is placed, press carefully to obtain correct adhesion and cover possible areas without adhesive. For a better fixing, it is recommended to set the pieces by using some tape or a wooden strip. To correct the position of the bases, it is recommended to take them off and correctly clean their back part before placing them again.

We recommend a minimum joint of 2mm and the use of crosspieces. For areas with severe thermal dilatation or non-stable surfaces (plasterboard), a minimum joint of 3 mm is strongly recommended.

DUNE recommends the use of SELF-LEVELING SPACERS to avoid the appearance of lippage between adjacent pieces.

The placement of a locked joint greater than 25% is not recommended to avoid the appearance of uneven or lippage between adjacent pieces. Claims of material placed on a locked joint greater than 25% will not be accepted.

Models manufactured with LUX resin components should not be installed in areas close to a heat source, such as behind radiators, in saunas, near burners, etc.

4. GROUTING

All joints must be perfectly clean and dry and having a minimum depth of 2mm. Use a flat rubber trowel to spread the paste, being sure that the joints are completely covered. Use a wet sponge or neutral PH products – never abrasive products – to wash off immediately the excess of grouting paste from the surface before it dries.

It is very important to do this before the paste dries. If this happens, use a cement remover to clean the surface

For better waterproofing, we recommend an epoxy grouting paste, especially in water areas

Items decorated by pre-cuts, so that it is recommended to follow the lines of those pre-cuts in order to get a correct finish. Make sure that the distance between one sheet and another is the same as the one of pre-cuts, so that all the joints look alike. It is not necessary to use crosspieces as the pre-cuts can be used as joining references.

Consult the grouting materials table.

Important:The colour of the grouting paste might change the product’s appearance. We recommend to test with some pieces before grouting the entire surface.

5. CLEANING AND MAINTENANCE

For everyday cleaning, use regular cleaners with PH neutral. Do not use abrasive products.

PVD AND DELICATED PRODUCTS: Avoid using abrasive and anti-lime cleaners or steel wool. Preferably use pH neutral cleaning products.

GLASS series’ items can be combined with the rest of CERAMIC tiles, as long as tiles are installed with joints in order to minimize the small size dissimilarities between pieces made of different materials.

References from the AURA series are sensitive to sun light. It is highly recommended to avoid direct sun exposure, even if they are installed on indoor walls (direct light through windows without curtains).

CUTTING AND DRILLING

STRIGHT CUTS: diamond blade wheel fitted with water-cooling systems.

DRILLING: Use a drill bit for perforating glass. We recommend using hollow drills with a diamond finish. The drill bit must be constantly cooled. Use the drill at a low speed and without hammer action. Do not apply excessive pressure on the piece while drilling; allow the drill bit to gradually perforate. Otherwise, the edges can break or cracks can appear later on. Be especially careful when the hole is about to be finished, this is the most delicate step.

Items with reliefs (VENEZIA) are difficult to bedrilled due to the glass internal forces. It is highly recommended not to do more than one hole and inferior than 8 mm in diameter.

It is very important to avoid applying coats of adhesive more than 3 mm thick, given that the shrinkage of the adhesive can generate defects at the back of some finishes (see attached photos).

It is essential that the pool is completely waterproof. We recommend using specific sealing materials. Make as many tests as necessary to ensure the swimming pool walls are completely waterproof. Please, note levelling materials are not waterproof.

3. INSTALLATION

We recommend starting the installation from the floor to the ceiling, continue in phase to allow the adhesive the necessary time to get dry. This will avoid vertical displacements. Extend a thin layer of adhesive on to the surface where the piece will be installed (3mm approx.) Then, use a notched trowel no. 3 to make incisions into the adhesive layer. Place the piece while the adhesive is still soft and before a dry layer of film forms on the adhesive surface. Once the piece is placed, press carefully to obtain a correct adhesion and to cover possible areas without adhesive.

Important: make sure that the distance between one sheet and another is the same as the one among the components so that all the joints look alike.
For irregular mosaics, we recommend pulling out some components and relocating them in the joint between two sheets. This will improve the finish of the mosaic.

Handcrafted molten glass mosaics present variations of both colour and shape between the different tesserae that make up the mosaic. Small imperfections and/or irregularities are considered to be a part of this process and, as a result, will not be grounds for complaint (CINEMA, GILDED, SALSA and BLUES).

LYRA, NICE, ALEGRIA, KANNA and ARGUS references, must not be exposed to natural light because the organic inks lose their colour.

IMPORTANT: SHOWER FLOOR: Where mosaics are installed on shower floors, it is highly recommended to apply an anti-skid product. DUNE recommends and sells ANTIGLISS.

CUTTING

Use special pliers for glass mosaics or radial disc for glass or porcelain water cooled.

Use a wet sponge or neutral PH products – never abrasive products – to wash off immediately the excess of grouting paste from the surface before it dries.

Consult the grouting materials table.

Important:The colour of the grouting paste might change the product’s appearance. We recommend to test with some pieces before grouting the entire surface.

TROPICANA NATURA: do not grout.

MADERA NOGAL, MADERA ROBLE y MADERA WENGUE have a low resistance to scratching. For a proper finish, use a fine grouting material. Excess of grout must be immediately cleaned with a sponge and water, avoiding excessive pressure. Be especially careful as it is at this stage of the installation when scratching is more frequent.

5. CLEANING AND MAINTENANCE

For everyday cleaning, use regular pH neutral cleaners. Do not use abrasive products.

TROPICANA NATURA: We recommend the sealer FILA PARQUET NATURE or TEAK OIL. The frequency will also depend on the use. Test the product on a piece to see the result.

WASHBASIN

INSTALLING THE WASHBASIN

General

The washbasins sold by DUNE are decorative. The only fixing point required to secure the washbasin to the surface on which it rests is the drain valve.

The drain valve should not be overtightened when installing the washbasin. If it is too tight, it could lead to cracks appearing in the washbasin.

Glass

In the case of glass washbasins, you should not use adhesives or silicone to fix them to the base, as this may lead to the back guard breaking due to the adhesive shrinking, which would affect the finish on the visible side. DUNE will not accept any complaints about stains appearing near to the drainage area if adhesives have been used to fix the washbasin to its base.

Glass washbasins should always be handled on a level surface, and avoid subjecting them to bumps and scratches, as breaking the washbasin’s back guard would affect the finish on the visible side. DUNE will not accept any complaints about problems with the finish caused by improper handling of its washbasins.

Stone

The shading of models made from stone may vary as they are manufactured using a natural product composed of veins of varying colours. This should be considered an inherent characteristic of the material which gives each washbasin a unique finish. DUNE will not accept any complaints about shading differences in stone washbasins.

Cement

As they are highly rigid, cement washbasins may crack due to rough handling, bumps or high pressure in the installation of the drain valve. Handle these products with care.

CLEANING THE WASHBASIN

It is recommended to use water, neutral soap and a soft cloth for daily cleaning. To prevent limescale stains, we recommend drying the washbasin after use.

Ceramic

These should be cleaned regularly with suitable cleaning products and rinsed with water. Do not use abrasive products to clean them, to avoid scratching the surface of the washbasin.
Repeatedly pouring away high-temperature liquids leads to stresses in the material, which may result in cracks forming to relieve the stresses. To avoid this phenomenon, DUNE advises against pouring high-temperature liquids into the washbasin or to do so gradually.

Stone

We recommend always using pH neutral cleaning products. Cleaning products with an acidic/basic pH may alter the colouring of the washbasin.

Metal

We recommend using soap and water or pH neutral products for cleaning. Do not use abrasive products to clean them, to avoid scratching the surface of the washbasin. Cleaning products with an acidic/basic pH may alter the colouring of the washbasin.

Cement

Do not pour products with a very high temperature into the washbasin, to prevent cracks from forming.
Repeatedly pouring away high-temperature liquids leads to stresses in the material, which may result in cracks forming to relieve the stresses. To avoid this phenomenon, DUNE advises against pouring high-temperature liquids into the washbasin or to do so gradually.

PVD (gold/silver finish)

We recommend using soap and water or pH neutral products for cleaning. Do not use abrasive products to clean them, to avoid scratching the surface of the washbasin. Cleaning products with an acidic/basic pH may alter the colouring of the washbasin.

FAQ’S

Which materials can and cannot be used for exteriors?

The use that you are going to put a base to depends on their porosity. As a general rule if the level of porosity is higher than 3% the tiles can only be used for interiors, while if it is above 6% then they can only be used for walls.
If the level of porosity is low (less than 3%) then the tiles can be used for both exteriors and interiors and on both floors and walls.
Although other criteria also exist to determine usage, absorption is the most widely employed.
Consult the usage table on page 318 and, in case of doubt, contact your commercial consultant.

What is PVD?

PVD is a decorative technique used to cover tiles with a metallic coating. This is a very fine film that highlights the features of the covered surface: shine, relief details… any irregularity or nuance will be stressed.
The PVD effect is particularly spectacular in the EXTRAVAGANZA Series, where the raised volume of the tiles is highlighted by the sheen provided by the PVD, which creates a fascinating play of light and shadow.
In technical terms PVD is an acronym for the process of “Physical Vapour Deposition”, in which pieces are passed through a reactor, inside which a vacuum has been generated, and are bombarded by a kind of metallic vapour, using an electric arc.
As a result of this process the metallic particles become firmly adhered to the surface of the part. This finish neither increases nor decreases the resistance of the tile, and the PVD products included in our catalogue are not apt for exterior use, given that the process is applied to porous materials that do not have the required water absorption index for exterior use.
