Pinto engineered products may either be glued down over plywood or concrete subﬂoors. They can also be nailed/stapled down over plywood subﬂoors, using a specially designed hardwood ﬂoor stapler or nailer.
1. GLUED INSTALLATION
- Suitable for concrete subﬂoor and on pre-existing ﬂoors such as: marble,Palladian ceramic, etc. Before the installation, it is necessary to verify the state of subﬂoor. Use a glue ﬁtting to the type of existing subﬂoor in order to avoid incompatibility or deformations of the elements which have already been oiled or painted and do not need any further intervention. Cleaning during the laying process is essential, since the waste of glue could damage the pre-ﬁnished ﬂoor.
2. NAILING OF TONGUES AND GROOVES
(only for 20 mm parquet) – After having chosen the best area in the room, align the board with the groove side along the wall, at a distance of at least 10-13 mm. For every listone-ﬂoor one or two 35-40 mm long nails must be inserted at 45° in the female part. THE NAILED INSTALLATION IS ALSO SUITABLE FOR: - Wooden ﬂoors set in work on joists - Wood panels made of wood by-products (in case of woody derived panels, we recommend an additional gluing of the ﬂooring boards).
3. INSTALLATION ON HEATING SUBFLOOR
Before installation check the humidity level of the parquet-ﬂoor: it should respect the recommended values. In case of ﬂoating ﬂoors, the thermal resistance of the underlay under the ﬂoor must be veriﬁed. In the case of glued ﬂoors, the glues used must keep enough plasticity over time and be suitable for the laying on heating subﬂoor. After the subﬂoor has dried, its humidity level must be measured (in case of concrete subﬂoor it must not overcome 1.5-1.7% in the anhydrite subﬂoor 0.2%). The subﬂoor is then heated for at least 2-3 weeks with a temperature gradually increasing by 5° per day up to the maximum temperature of exercise of 35°C (which is kept for about 2 weeks). The heating is then turned oﬀ for 4-5 days (with the temperature gradually decreasing) before the installation takes place. Afterwards the heating can be turned on again, with the temperature gradually increasing up to normal levels. It must however be kept in mind that, according to the characteristics of the wood, the formation of gaps in the ﬂoor during the period of heating cannot be excluded.
