Installation and cleaning


Before laying

Firstly, we have to verify that the model, size and quality impressed in the box are the same as per the order.
Next, we have to open some boxes to check that the model is the same as that one written in the delivery note.
Once we have checked the product is the correct one, we have to prepare the surface where the material is going to be laid. This surface must be clean and smooth.
When we are working with floor tile, we have to place some pieces on the surface to see their effect.
For modular installation, we must ask the factory for compatible caliber and shade.

During laying

The material used for laying tiles depends on the characteristics of the laying surface, the kind of ceramic product, climate conditions and its use.
Recommended adhesive: H40 Eco Flex by Kerakoll – adhesive C2 E according to UNE 12004/12002. Highly deformable for the laying of porcelanic material, both interior and exterior surfaces. Specially recommended for the laying of stuck facades, highlevelled flooring, high traffic….. available in white and grey colour.
Using the correct tools it is a very important point when laying tiles (rubber mallet, rubber float for pointing, toothed tiling trowel, etc.)
The sides of the tiles have to be clean and they have to be placed in perfect alignment.
For a better results use The Ceramic Levelling System of PEYGRAN
1.- Adjust the pliers according to the ceramic thickness. Place the crossheads.
2.- Lay the next ceramic tiles and put the wedges.
3.- Press the wedges with the pliers.
4.- Lay the ceramic tiles around and do the same.
5.- Once mortar is set, hit the crosshead on its corner, in the same direction of the join. After all, pick up the wedges for later use.
When laying tiles in an offset pattern, they must be laid with a distance maximum 20% of the length of the tile. Excepting Chelsea´s collection where we advise 15% as a maximum.
DURSTONE porcelanic is rectified with a microbisel to avoid chips. Joints, when laying this kind of product, must be of 2 mm indoors and up to 3 mm outdoors.
When sealing the joints, it is important to use specified products ( we recommend Fila MP/90); this sealing must be made using rubber float once the adhesive has completely set and, always, respecting the material’s application times. Then, joints can be cleaned using a soaked sponge.
In those areas which surface is larger than 8 sqm, the joint must be of 5 mm around the whole perimeter; on the other hand, in those areas with a surface larger than 50 sqm indoors and 30 sqm outdoors, partition joints must be used in order to absorb any possible movement.

After laying

Once joining is finished, the excess material has to be removed before it dries and hardens and, also, the tiles must be cleaned using non-abrasive products, avoiding the use of hydrofluoric acid. After this, tiles can be cleaned (we recommend DETERDEK or Fila PS/87).
Once laying is finished, it is important to cover all the floor using cardboard or other elements in order not to damage the laid product.


To remove remains of dust and solids: sweeping or vacuum cleaning.
Do not use dust-catcher mops with silicones and waxes.
The surface must be washed with neutral soap and the amount of hot water recommended by the manufacturer.
Do not use cleaning products containing wax, brighteners or similar additives, since in time they may leave a waterproof layer on the tile which alters its surface appearance. If this occurs, Durstone, recommends cleaning the surface with dry cleaning products (detergents in powder form) and cleaning the tiles as indicated above.
Before using any chemical product for cleaning, it is necessary to check its effect over the surface of the ceramic or porcelanic product, using it over a non-visible area to see its effect over the product.
When flooring porcelanic material we have to be careful in both the initial and the final cleaning because, during the polished process, the micropores in its surface open up; this means that they are more vulnerable to be stained by certain liquids. It is also important that any product that may affect polished porcelain tiles (oil, fizzy and alcoholic drinks, acids, etc.) must be cleaned using water as soon as possible in order to avoid they become stained.

After-sale service

It is very important the checking of the supplied product before laying it as we do not accept any claim over already laid product. Therefore, if any anomaly in the product is observed, the factory must be informed about them before laying the material.


When using rectified porcelain product it is recommended tiling using ceramic levelling System of PEYGRAN.
Seiling using Fila MP/90 and cleaning and maintenance using Fila CLEANER.
