1) The assembler shall be granted a clean and dry assembly space, free of any furniture or tools, devices, aggregates or equipment that might hinder the floor assembly-mounting activity. It is recommended that the floor be mounted last in the order in which the respective space is finished. Any danger of water infiltration or excessive humidity shall be eliminated, as its penetration during or after the mounting might compromise the quality of the floor. A temperature of 15-25 degrees Celsius shall be ensured in the mounting space. The relative humidity shall be between 40% and 65%.
2) The specifications comprising the surface sizes, mounting heights, axes, treading finishing and other requirements of the designer/beneficiary shall be made available to the assembler and established in due time before mounting in order to calculate the necessary materials and mounting order.
3) The support surface shall be delivered clean, dry, plane, firm, without cracks or empty spaces, without chemical stains (grease, oil, etc.). The contraction of the support-floor shall be taken into consideration so that in the future there shall be no size variations. Also the support surface shall be made to support a load equal to that of the sum between the floor weight and the maximum of its load, both specified by the assembler.
4) Any operations for mounting the electrical and water installations under the floor shall be completed before starting its mounting. Any installation under the floor shall be at least 12 mm from the wall in order to adequately position the carrying structure. The plastering of the walls shall be completed 60 days and the painting (washable paint) 30 days before mounting the floor. The surfaces coming into contact with the floor shall be firm and resistant to vibrations or shocks sent by it.
5) The assembler shall have electrical power and water sources and in the mounting space other persons’ access shall be forbidden from the moment of installation until 1 day after its completion. A storage space shall be ensured whose security is the responsibility of the beneficiary/contractor in the vicinity of the mounting space
FLOOR MOUNTING
Before starting the mounting the level differences of the support hoe (with laser leveler) shall be checked in order to verify, on the mounting level, whether the floor to be mounted fits in the adjustment interval of the structure. Also the quality of the hoe shall be checked by recommending an anti-dust treatment with special paint. This treatment is indispensable if the space under the floor is to be used as air conditioning tubing.
Pedestalsshall be fastened on the support hoe either by dowels or by gluing with the adhesive recommended by QUATTRO, both variants being accepted from a technical point of view
1) ) The mounting shall start by tracing 2 axes perpendicular on the floor of the room, parallel to the sides of the panels to be mounted (fig. 1).
2) The structure shall be laid down by complying with modularity 600 x 600 mm, starting with point 0 (see figure 1) by avoiding, following its placement, panel cuts under 15 cm (fig. 2).
Fig 2
3) Variant A – Fastening the structure, mounting the panels and adjusting the floor shall be performed in parallel.
4) Variant B – After completing the placement of the structure (only base supports or base supports + beams) the level of the entire structure shall be adjusted for horizontality.
5) Panels shall be placed in order to obtain a T shape starting with the first row, on the two perpendicular axes (fig. 3).
Fig 3
6) The perpendicularity of panel placement shall be checked (fig. 3).
7) The placement of the panels may continue on 2 directions opposite to the obtained T shape.
8) The last to be mounted shall be the panels that make up the perimeter, after they are cut to size. If the structure is only made up of adjustable base supports, these shall be fastened to the floor by adhesive gluing. In this case the structure shall be fastened and adjusted separately and concomitantly to laying down the panels. Traffic shall be allowed only after 48 hours
