Installation of Weitzer Parkett


Prior to installation

WP Charisma with the intelligent, patented double-click system was designed for a glue less floating installation. for installation in damp rooms, complete adhesion and appropriate care in handling is required.

We recommend a gluing of header joints which have been installed and opened again. the application of glue is demonstrated in Illustration 3. this is also recommended when the evenness of the subfloor is bordering on the acceptable limits. In higher traf c areas or in usage with under oor-heating, we recommend complete adhesion.

The maximum surface temperature must not exceed 26°C. Higher temperatures may lead to irreparable defects. Please consult a professional for best advice and a professional installation in those cases. to improve the visual impact, we recommend that installation is oriented towards the source of prevailing daylight. In small, narrow areas (e.g. hallways) we further recommend that installation follows the length of the space/room. floating  oor installations wider than 8 m require an additional expansion joint.
the base for a  floating-floor installation must be clean, dry, even and solid. all wall-to-wall carpeting must be removed. existing PVC or linoleum  floors may, depending on their condition, serve as a suitable base. Please test the base for evenness. Variations of more than 3 mm per 120 cm must be levelled out with a suitable levelling compound. failure to ensure a level base may cause the floor to  ex resulting in possible damage to joints and/or the interlocking mechanism.

Maximum Allowable Residual Humidity (MARH) as measured by appropriate instrumentation:
Concrete floor: according to Önorm B2218: 2%
Anhydrite floor: up to 0.3 %

When planning an underfloor heating system, please apply the following MARH standards:
Concrete floor: according to. Önorm B2218: 1,8%
Anhydrite floor: up to 0.3 %

In new-construction applications we strongly recommend that MARH is measured professionally. In slabongrade construction, it is essential to install an appropriate vapour barrier.

Illustration 4: required tools: tape measure, pencil, jigsaw or piercing saw, square.

Illustration 5: at using the 2.5 mm, natural ber underlay WP Sekura, or the 2 mm cork mat, ambient sound is reduced. the concrete has to be coated by a 0,2 mm Pe foil before. make sure to overlap any joints by at least 30 cm. Do not use underlays which are too soft, as this may cause the oor to ex and resulting in possible damage.


During installation

WP Charisma must be installed only in rooms that are ready for occupation. the ambient temperature must be at least 18°C with a relative humidity of between 40 – 60 %. allow the original packages of WP Charisma to acclimatise for several days on site and do not open the packages until immediately prior to installation.

Wood is a natural product. Variations in colour and/or grain are not only possible but in fact are a normal characteristic. We recommend that installation proceeds simultaneously from 3 or 4 packages to assure a cross section of grain and colour. Material defects discovered after instal- lation are excluded from warranty.

Illustration 6: once the direction of ins- tallation is determined, start with the rst board in the left corner of the room.the longitudinal joint (Illustration 2 see arrow) must face the wall. maintain a distance of at least 10mm from the wall.(you may elect to use spacers to maintain the appropri- ate distance). It may be an advantage to completely t and interlock the rst three rows of boards and then to carefully slide them towards the wall where the 10 mm distance is maintained. With this approach, installation may proceed without the need of spacers. If the wall is not straight, the first row of boards must be fitted to maintain the minimum distance of 10 mm throughout.

Illustration 7: the remaining boards of the rst row may now be installed. Carefully align the board ends and engage the in- terlock by using a rubber mallet. a tight t is an indication that the interlock has properly engaged. If the cut off at the end of the rst row is longer than 40 cm, it may be used as the rst board of the second row etc. see Principles of Installation (Il- lustration 1).

Illustration 8: Interlock the rst board of the second row alongside the rst row by exerting simultaneous pressure against row one and pushing downward.

Illustration 9 & 10: subsequent boards are rst positioned at an angle along the rst row, and the headed board ends are pressed tightly together before engaging the interlock. a sideways and downward pressure will then lock the boards to- gether. Please ensure that no open joints are visible and take care not to damage the edges.

Illustration 11: Use the square to mark the correct length of the last piece in the row. maintain a distance of at least 10 mm between the cut end and the wall.

Illustration 12: measure the last row; cut where necessary and click into place. re- member to maintain the 10 mm gap with the wall. If the last row is less than 10 cm wide, it should be edge glued to the pre- vious row.

Illustration 13: for wooden or metal door frames, you are advised to establish an expansion joint of at least 3 mm. another option is to shorten the frames that the parquet oor can be pushed underneath.

After installation

Humidity should not be lower than 40% during heating period.
the lower the humidity the higher the risk of irreparable defects of the floor.

We recommend removing abrasive dirt with broom, mop or vacuum cleaner. Wa- ter, sand and stones should be removed immediately. Dust and dirt shall be removed with slightly damp cloth.

Do not flood the floor with water. Depending on surface finish of the floor, add the Weitzer Parkett recommended cleaning agent to water.
