4.1.3.1 Protection of areas ad spaces not subject to the work

Prior to surface preparation and wooden floor applications, remove, mask, or otherwise protect, machined surfaces, radiator covers, plates, lighting fixtures, public and private property, and other such items not to be coated that are in contact with surfaces to be coated.

4.1.3.2 Wooden Floor Application

Different type of wooden floor application:

• Nailed: for this technique, the oldest and most expensive, it is necessary to use staves at least 1.8 cm thick and a layer of wood to be able to fix the nails.

• Glued: installation carried out with special glues applied to the pre-existing floor, an intermediate layer is not necessary. This technique is the ideal one for laying solid wood parquet.

• Floating: Ideal for prefinished parquet, laying floating or "floating" parquet does not use nails, glues or other supports. It consists in placing the parquet on the base by hooking the slats thanks to T&G decking joints. To guarantee soundproofing, protection from humidity and thermal insulation, insulating material or soundproofing adhesive is placed between the wooden slats and the old floor. Being an interlocking installation, the advice is to opt for large and therefore heavier lists, so as to minimize movement.

If the underlying floor is valuable, the best option for laying is the floating one:

a layer of functional insulating fabric is laid to make the planks adhere to the laying surface, thus avoiding the formation of voids which can damage the parquet and amplify noise from trampling.

To lay the parquet on an existing floor, the initial height will rise by 1-1.5 cm, so it is essential that the professional check the level of the fixtures during the inspection.

- 23 -

Prepare and clean the substrate, checking its flatness, compactness and absence of humidity. In the presence of defects, smooth or use a self-leveling product.

Smooth the substrate with a pumice stone to favor the adherence of the glue.

In the case of walls that are not perpendicular to each other, square the room, tracing perpendicular lines, to refer to when laying the first row of strips.

Apply the leveler with suitable materials, starting from the point furthest from the door, pouring gradually and insisting a little on the marked and grouted areas. Wait about 3 days before laying the parquet.

Spread the glue evenly with a notched trowel, without excesses that could create imperfections as creating air bubbles between the screed and the wooden floor. Dose the optimal amount of glue for good bonding and use single-component adhesive with a silanic termination that reduce noise, recommended for gluing of pre-finished wooden floor onto marble, grit, ceramic or marble-chip floor tiles and with acoustic insulation.

Proceed with the application of the wooden floor, and baseboard if required by the contract, agreed with the C.O.R. Lay the strips and with a rubber mallet and spirit level, make sure that the strips adhere to the substrate, are perfectly aligned and do not present flatness problems.

Space the slats 1 cm from the walls to compensate for the expansion of the wood as a result of temperature changes.

Glue the skirting board on the walls.

4.1.3.3 Finished Surfaces

Provide finished surfaces free from runs, drops, ridges, waves, laps, works marks, and variations in colors. Apply special water-based or synthetic resin varnish to the parquet, creating a film that tends to uniform the surface of the wood, making it particularly bright and resistant to abrasion and absorption.
