Pure Paper Color panels are processed and bonded in the same manner and to the same substrates as all the laminate panels available on the market. Please refer to the French "NF T 54-320 standard "Installation of High Pressure Decorative Laminates" for additional information. See below.
Press Gluing : Using a cold-press or hot-press machine is the safest gluing method. When opting for this method, use standard laminate glues such as vinyl or urea formaldehyde. Do not exceed 70° C (160° F) when using a hot-press machine.
Gluing without a press : A large number of neoprene glues produce satisfactory results. We recommend in particular the Agoplac and Pattex brands. Gluing must be done in an environment with an ambient temperature between 18° and 22° C (65 and 72° F) and a relative humidity between 40 to 60%. Strictly follow the manufacturer's instructions for basis weight and open times. Roller-pressing operations must be performed using appropriate rollers.
The panels can be applied to all kinds of base material having a perfectly flat and thoroughly clean surface, such as particle board, MDF, etc, with the exception of solid wood.?Gluing to metal requires careful preparation of the surface, particular attention being paid to thorough degreasing with a strong solvent (trichlorethylene, etc...). Bonding on cement or gips substrate is to be avoided.
For best results, use Pure Paper Color balancing panels of the same thickness on both sides and position them in the same direction. When using a balancing panel other than Pure Paper Color, prior testing must be performed in accordance with the project's specifications (Format, thickness of the substrate, wall installation).
Sawing, milling, and drilling operations are performed using machines commonly used for machining laminate panels.
Aligning raised patterns between several panels
Dimensional and structural variations are generally inherent to the laminated panels.
These dimensional and/or structural variations are mainly due to the components, the manufacturing process (structural variations before trimming) and also storage conditions (dimensional variations after trimming).
Textured Pure Paper Color laminate sheets meet the EN-438 and accept structural and dimensional variations of 10.5 millimeters per meter widthwise and 5.5 millimeters per meter lengthwise.
Therefore, the geometric raised patterns in the Color and Metal lines (all products except Skin and Figured) should not be expected to be perfectly symmetrical and/or connectable.
Recommendations to take into account for an optimized application
Proper installation following the few recommendations listed below will help optimize the visual homogeneity of raised patterns between panels.
Advice n°1. Storage
The Pure Paper laminate sheets as well as the various components used as part of the installation (substrates, backing boards) have to be stored flat in an enclosed space, away from humidity with a hygrometry level between 40 to 60% and a temperature between 18°C to 22°C.
Advice n°2. Tracking the serial number
It is preferable to keep track of the serial numbers of the Pure Paper sheets to organize the order of the installed panels. Please note that in a same series, the dimensional and structural variation between two sheets is limited.
Advice n°3. Following the orientation of the sheets
Follow the top and bottom orientation of the sheets when doing the pattern layout (coloured marker on the bottom left corner of each sheet).
Advice n°4. Avoiding mixing length
Avoid mixing standard length panels (2500 mm) with long-length panels (3050 mm).
Advice n°5. Managing the first sawing
Pure Paper sheets are always supplied with the left long side aligned to the first line of patterns. For each Pure Paper sheet, take into account this point of reference to align the panel with the sheet. Therefore, it is recommended to respect this side of reference when gluing the panel on a base material or for the first trimming.
Advice n°6. Opting for the visible part
Set optimal alignment points (or areas) at eye level.
Advice n°7. Providing an open-joint
A space (open-joint) between 2 panels helps limit or eliminate the visual impact of incorrect pattern alignments that may occur.
