1. Preparing the surface
   • Check that the floor is clean, dry and perfectly smooth.
   • Level out any irregularities by filling in the surface if necessary.
   • Apply a primer for better adhesion.
2. Acclimatising the parquet
   • Leave the parquet to acclimatise in the room for 48 hours before laying.
3. Choosing the laying method
   • Decide on the right method: floating, glued or nailed, depending on the type of parquet and the support.
4. Deciding on the direction of installation
   • Install the boards in the direction of the light or parallel to the longest wall.
   • Do a dry run to visualise the result.
5. Installing the underlay
   • For floating installation, install an insulating underlay.
6. Laying the boards
   • Start against a wall, leaving an expansion gap of 8-10 mm.
   • Use shims to maintain this space.
   • Join the boards together by interlocking or gluing them, depending on the method chosen.
7. Adjustments and cutting
   • Use a suitable saw to adjust the boards to the contours of the room.
8. Finishing touches
   • Remove the expansion spacers.
   • Install the skirting boards and threshold bars.
9. Final check
   • Check the alignment and stability of the boards.
   • Make sure there are no gaps between the boards.

By following these key steps and taking the necessary time for each phase, you will guarantee perfect installation of the parquet, thus ensuring its longevity and appearance for your client.

For a professional parquet floor installation, whether for a new installation or a renovation, the following tools are essential:

Measuring and marking tools

• Tape measure
• Pencil
• Set square

Cutting tools

• Jigsaw or circular saw
• Box cutter

Installation tools

• Hammer or mallet
• Striking block
• Blade puller
• Expansion spacers

1. • Belt sander (for renovation) or multi-disc type 4D depending on your habits, the size of the space and the type of surface
   • Edger (for areas that are difficult to access) much more efficient than manual sanders.
   • Vacuum cleaner or central vacuum system
2. Inspection tools
   • Spirit level
3. Protective equipment
   • Gloves
   • FFP2 mask (for sanding and sealing)
   • Slippers to avoid leaving marks
   • Knee pads to look after your joints too!
4. Specific tools depending on the installation method
   • For glued installation: notched trowel and suitable adhesive
   • For sealing: roller or trowel, depending on the surface

These tools enable you to carry out all the essential stages of a professional installation, from preparing the surface to finishing, ensuring precision, efficiency and quality of work.

1. Inspection and cleaning
   • Carefully examine the existing surface for any damage or loose parts.
   • Remove the old floor covering and skirting boards if necessary.
   • Thoroughly clean the surface, removing all traces of grease, residue and glue. Consider using the glue pads, accessories of your Multidisque 4D or the new ranges of dedicated abrasives.
2. Humidity control
   • Check the humidity level of the surface with a moisture meter.
   • For a cement screed: < 2.5% CM (75% RH).
   • For an anhydrite screed: < 0.5% CM (50% RH).
   • For a wooden surface: < 10% humidity.
3. Hardness control
   • Check the hardness of the substrate with a moisture meter. The Mohs® hardness test kit offered by Repex is an essential tool for craftsmen specialising in polished concrete, decorative and hard floors. This kit allows for a quick and efficient evaluation of the hardness of the concrete surface on a scale of 1 to 10, where 10 represents the hardness of diamond. By determining the scratch resistance of the surface, professionals can make informed decisions about the choice of diamonds to use and the sanding method to adopt. This precise evaluation not only optimises the work process, but also potentially saves hundreds of diamonds and many hours of work, thus guaranteeing a high-quality end result for the treated floors.
4. Checking flatness
   • Make sure that the surface has no irregularities greater than 2 mm per metre and 1 mm per 20 cm.
   • Use a ruler and a parquet knife to check the flatness.
5. Levelling
   • If necessary, apply a levelling compound to correct any irregularities.
   • Use a spatula to smooth the surface.
6. Application of a bonding primer
   • Apply a primer suitable for the type of substrate to improve adhesion.
   • For porous substrates, use a specific primer.
7. Laying of an underlay
   • For a floating installation, install a polythene film as a moisture barrier.
   • For glued installation on a surface with a humidity level of between 3 and 10%, use an insulating underlay.
8. Acclimatisation of the parquet
   • Leave the parquet to acclimatise in the room for at least 48 hours before installation.
9. Specific preparation according to the surface
   • On old parquet of no interest: lightly sand the surface with coarse-grained paper.
   • On tiling: make sure the tiles are properly fixed and level if necessary.

By following these steps, you will create the optimal conditions for successful parquet installation, thus guaranteeing its longevity and appearance for your customers.

To renovate a wooden floor properly, it is essential to have the right tools and accessories to ensure efficient, accurate and safe work. Here is the main equipment you will need:

• A floor sander, essential for stripping the surface and removing the old finish. Large areas usually require the use of a belt sander or ride-on sander.
• An edge sander, which allows you to treat edges, corners and hard-to-reach areas such as those near skirting boards.
• A triangular or multi-function sander, useful for tight corners, pipe contours or confined areas.
• Sandpaper of various grades, to be used progressively, from coarse to fine, to achieve a perfectly smooth finish.
• A powerful vacuum cleaner, essential for removing dust between each stage of sanding and keeping the area clean.
• A spatula and wood filler to fill cracks and holes before final sanding.
• A hammer and mallet to readjust the boards and hammer in any protruding nails.
• Rags and a mop to clean the surface before applying the finish.
• Protective equipment such as gloves, goggles, a dust mask and, if necessary, ear defenders.
• Application tools such as a brush, roller or spalter, needed to apply the chosen finish (varnish, oil or wax).
• The finishing products themselves, suitable for the type of floor.

Depending on the condition of the floor, other tools may also be useful:

• A jigsaw and a drill to replace damaged boards.
• Wood filler or a mixture of sawdust and resin to fill large gaps.
