Bonded Dalsouple® tiles have two sides: one side is sanded to ensure proper adhesion of the glue and the other side is the side visible once the tiling is installed.


Choice of tools and materials not supplied by Dalsouple®

All materials and/or equipment must be used in accordance with the instructions and directives of the associated suppliers.




Choice of adhesive

The tiles may be laid with different adhesives depending on where they are installed and their intended use. Whatever the adhesive you intend to use, it is important to follow the manufacturer's instructions to ensure proper installation. Carefully follow the recommendations regarding the technical time to be observed when using their adhesive (gumming and open time that define the sequence of bonding operations and working times).

Generally speaking, the bonding operations must be performed in an aerated room while wearing the appropriate personal protective equipment (e.g.: gloves, mask, etc.)

Two-part adhesive:
These types of adhesives are recommended for applications outdoors or in humid environments.
- Epoxy adhesive (Bostik SOLFIX EP60 type)
- Polyurethane adhesive (Bostik EPONAL PU456 or Bostik SOL NM type)

Emulsion adhesive:
Acrylic adhesive: recommended at HEQ sites. They are sensitive to water and humidity (Bostik POLYMANG HPE or SM type).

Contact adhesive:
Neoprene adhesives can be used (double spread) depending on local legislation, as they contain volatile and flammable solvents. (Bostick NM type floor adhesive).

Dry adhesives:
"Double face" type adhesives are used in certain configurations and particularly allow for nearly immediate use of the tiled surface. Some of these adhesives allow Dalsouple® tiles to be laid on an unequal floor surface (such as ceramic floor tiling).

Please consult us.


Selecting a trowel/spreader

The trowel/spreader is chosen based on the type of glue used. It is important to follow the adhesive supplier's recommendations.

Dalsouple® tiles require a smooth or finely serrated No. 2 or A2 type trowel (TKB standard) to spread 250 to 300 g/m² of adhesive and to ensure that the tile surface is covered completely and regularly.


Before installation

Check that the tiles are properly packed: damaged packaging may indicate that the quality of the Dalsouple® tiles has been compromised.

We recommend you check your layout plan by loose laying the tiles before applying adhesive to the substrate. No claims shall be entertained if the tiles have already been laid.
Note: the colour of the tiles may vary slightly compared to the samples presented and according to which the order was placed.
This may be due to the difference in the date of manufacture, which necessarily leads to slight pigmentation variations in the gum.

The tiles must be stored together in the same neutral physical and chemical environment (temperature > 10°C under shelter, humidity < 75 % , atmospheric pressure, neutral pH, etc.). This storage should be as short as possible and must not exceed 1 month to avoid slight variations in size before bonding (bonding the tiles eliminates this phenomenon).
The storage location must be dry, protected from inclement weather, mechanical stresses and/or chemical and direct sunlight.

To avoid condensation on the tiles, resulting in reduced bonding efficiency, they must be stored in job site conditions at least 48 hours prior to installation.

In case of cohabitation with chemicals, every precaution must be taken to protect the Dalsouple® tiles.
In particular, our standard Dalsouple® references are not guaranteed against oils and hydrocarbons of any kind. Special tile references, created for these types of applications, are available in our product range (consult us).
Unless a specific request is made for a special tile reference, the standard reference will be manufactured.

 

Preparation of the substrate

The substrate must be prepared by professional flexible rubber flooring installers in accordance with current trade rules and/or regulations in the country concerned. For France, DTU 53.2 must be respected with regard to the rules governing substrate acceptance.
Compliance with these rules and therefore the success of the installation does not fall within the scope of responsibility of Dalsouple® as it has no control over the work performed by the installer.

In addition to this regulatory framework, the specific characteristics of Dalsouple® flooring must be taken into account.
The risk of rising damp must be completely eliminated (in particular, cement screeds must be completely dry without risk of rising damp - refer to the construction standards in force in the country or location in question, especially regarding the measurement methods).
If a risk is present, provide a special barrier sub-layer.

The installer must measure surface porosity and moisture content in accordance with current standards before the tiles are installed (recommendation: sufficient porosity to allow the adhesive to bond and screed humidity below 3 %).
A non-compliance shall result in the immediate implementation of corrective measures.

Dalsouple® products must be installed on a P3 class thin set mortar (thickness > 3 mm).
Any other configuration shall be the responsibility of the installer.
The substrate must be sufficiently hard so as to resist marking in case of a concentration of short-term load (e.g.: the passage of someone wearing spike heels).
The floor must be perfectly clean and flat, without cracks, waviness, holes, bumps and free of any defects that may affect its flatness and/or strength.

It must be cleaned of all cement grout and laitance, particles or dust (e.g. thin-set mortar sanding dust ) and in general, all elements likely to interfere with the bonding of the Dalsouple® tiles.

Preparation of the installation

All our floor coverings must be laid by professional flexible rubber flooring installers in accordance with current trade rules and/or regulations in the country concerned. Compliance with these rules and therefore the success of the installation does not fall within the scope of responsibility of Dalsouple® as it has no control over the work performed by the installer.

If coloured tiles and/or tiles with multiple textures are used, experience has shown that it is better to define the order and position of each type of tile before starting to bond the tiles (layout).
The installation must be performed at a temperature between 10°C and 30°C; humidity should be below 75 % (refer to the adhesive supplier's recommendations).
The temperature gradient between the tiles and the laying area must be low enough to avoid condensation.

The room must be sufficiently ventilated to allow the adhesive to dry.

To avoid any risk of damaging the Dalsouple® floor covering by other work in progress, it must be laid last and in a single operation depending on the areas concerned.
If this is impossible, the area must be covered by an appropriate system of protection throughout the construction period.
In order to limit the risk of soiling and damage to Dalsouple® floor coverings, an effective passive protection (such as a floor mat) should be placed at the entrance of rooms where tiles have been laid.

Installation method

Once the floor has been traced to prepare the positioning of the tiles, the floor is then coated with adhesive (see "Choice of adhesive"). For aesthetic reasons, we recommend that the tiling operation begin at the centre of the room.
We also recommend that the tiles be laid in a "brickwork" (staggered) fashion as this pattern will minimise any difficulties associated with tile alignment.

The bonding surface of Dalsouple® floor tiles have been sanded. The back of the tiles must therefore be brushed slightly prior to installation. Doing so will ensure that the surface is free of any material, debris, residue or other foreign particles that could interfere with bonding.

The use of joints is prohibited. The tiles are to be glued flat, without stress, edge-to-edge with no gap between them; the corners must be in perfect contact with no spaces.
The formulation of the Dalsouple® tiles allows them to be perfectly butt-jointed (edge-to-edge).

Any excess adhesive should be cleaned immediately as its removal becomes delicate once it has dried.

For whatever reason, any interruption of the tiling operation must allow operations to be resumed in the same conditions.
All surfaces to which adhesive has been applied must receive a tile, even it is just partly glued. When laying operations resume, additional adhesive may be applied to finish the bonding.
Once the glue has dried, it cannot be removed without undermining the floor's flatness and the ability to lay the tiles edge to edge.
The job site must be fully completed before opening it to foot traffic.
Otherwise, all such areas must be fully bonded and carefully protected from damage until the project is completed.

Do not walk or press on the tiles until the adhesive has fully dried. Adhesive that has not dried completely may be expelled under the contact points and the flatness of the tiles may be affected.

The tiles must be laid without any stress and must be followed immediately by light and careful pressing with a suitable cork squeegee. Pressing by hand should be avoided as it may deform the Dalsouple® tiles owing to their flexibility and elasticity.

In order to completely remove trapped air bubbles and ensure that the adhesive is uniformly spread over the entire underside of the tile, a second pressing operation is performed 30 min. to 1 hour after installation (depending on the adhesive and weather conditions - refer to the adhesive manufacturer's recommendations).
Pressing operations should be performed with a 40 kg roller.
As a guide, bonding is considered complete when substantial mechanical force is required to remove the floor covering; the floor or the substrate would be partially damaged.

The tiled area may be opened to foot traffic 48 hours after laying.

Installation on floors with underfloor heating

Dalsouple® tiles may be laid on floors with underfloor heating.
The substrate must be perfectly stabilised (refer to the underfloor heating manufacturer's recommendations).
The underfloor heating system must be turned off at least 5 days before laying the Dalsouple® tiles. Once the adhesive has dried, restart must then be progressive and spread over 1 week.
The adhesive for floor without underfloor heating is suitable for floors with underfloor heating.


Installation without adhesive

Certain Dalsouple® tiles may be loose-laid without adhesive as their high density allows them to stay in place.
Their special design allows them to mechanically interlock with one another, like a puzzle, allowing them to be disassembled and reassembled as required.

These tiles must be laid with a 3 cm expansion joint along the perimeter of the area and around all fixed points in the site (along walls, partitions, pillars, furniture, etc.).
This expansion joint will fill in progressively over a few months.
If this instruction is not respected, the tiles will eventually begin to become deformed and/or overlap one another. In this case, the only way to free them would be to cut around the mounting point.

The floor must be prepared in the same way as for any Dalsouple® bonded floor covering.
The humidity rate is not an important factor in securing these tiles. They must be stored at the job site at least 48 hours before laying operations begin. Laying operations must be performed as quickly as possible in order to accelerate job site stabilisation.

It is recommended that the corners of the tiles be bend downward slightly when laid to facilitate their placement and attachment.
These tiles may be bonded. In this case, refer to the recommendations concerning installation with adhesive.

In heavy traffic areas such as in work areas with machine traffic, sections subjected to machinery rotation must bonded according to our recommendations concerning bonded floor tiles. Failing this, the tiles may come apart.


Job site cleaning
and 1st waxing

After drying and before it is opened to circulation, the job site must be carefully cleaned. All traces of dust, dirt, grease, sand or other debris must be completely removed.
Prior cleaning is recommended. To do this, apply Dalsouple® TR20 type cleaner, diluted 1:10, with the green disc buffer (as per 3M classification for Scotchbrite discs).
Allow to react a few minutes, rinse then vacuum the excess liquid.

When the floor is clean and dry, apply the Dalsouple® liquid polish/wax which will form a nourishing and protective film on the surface of the tiles.
This first application is very important as it will facilitate subsequent maintenance.
The wax must be applied in two thin cross coats with a foam mop or polisher which will dry rapidly (1 litre for 50m²).
Allow the wax to dry 1 hour between coats.

Two additional applications of wax must be performed during the following month, on a clean and dry floor. In the case of heavy traffic or exposure to intense sunlight, do not hesitate to repeat the operation.
Waxing the floor promotes the overall protection and appearance of the flooring. Dalsouple® tiles will maintain their lustre when sufficiently nourished.
Dalsouple® also proposes gloss or matte-finish waxes.

Maintenance

Routine maintenance

- A periodic maintenance in accordance with our recommendations is necessary to maintain the aesthetic appearance and service life of Dalsouple® floor coverings.

- The waxing is imperative for subsequent maintenance operations.

- The floor covering is cleaned with a low-speed buffing machine equipped with a red disc or an industrial washer using Dalsouple® TR20 cleaner, 1 litre for 100 m² diluted 1:10 (if another cleaning product is used, a small area must be tested first. Do not use products that are incompatible with one another - carefully follow the manufacturers' recommendations).

- Spread the mixture, allow it to sit for a few minutes, vacuum the product and the cleaning residues before it dries, then carefully rinse with clean water and allow to dry. No residue must remain on the floor.
Once the floor is clean and dry, a film of wax may be applied. Doing so will increase the floor's lustre and enhance its protection . High-speed polishing is possible.




Special maintenance

- If routine maintenance of the Dalsouple® flooring is no longer satisfactory, the wax film may be damaged or dirt has become captured in the wax as a result of improper cleaning. In this case, we recommend through deep cleaning of the surface and complete rewaxing in accordance with Dalsouple® recommendations.

- Proceed in the same manner as with routine maintenance but use the Dalsouple® TR20 cleaner pure. Let it sit 10-15 minutes, depending on the amount of dirt and grime. Spread the mixture, allow it to sit for a few minutes, vacuum the product and the cleaning residues before it dries, then carefully rinse with clean water and allow to dry. No residue must remain on the floor.
Use a green disc.
Adapt the amount of pressure applied and the speed of the buffing machine to the situation.
We recommend that a preliminary test be performed on a small area.
A single pass is usually sufficient to remove damaged film of wax.

- At this point, the floor can be rewaxed in the same manner as for the first waxing operation (see "Job site cleaning and 1st waxing"). The floor will rediscover its original lustre.


Stains

In all cases, immediately treating stains promotes their removal without consequence for the Dalsouple® flooring.
Certain types of stains require special treatment.
