Click parquet installation guide, Puudelicatessen Collection & Esta Parket

The laying direction of the parquet panels should be decided before installation begins. The direction will depend on the shape of the room and the position of the windows. We recommend laying the panels along the longer wall and/or parallel with the natural lighting. Having determined the direction, the room width must be measured. This width should be reduced by 25 mm (for expansion gap) and divided by the width of a parquet board. In this way the number of rows of parquet boards can be calculated, as well as the width of the last row. If the last board width is narrower than 70 mm, then we recommend that the first board to be laid should also be trimmed in order to give a pleasing balance to the finished floor. In any case, the installation will begin the small tongue towards the wall and the first row must be trimmed to the shape of the wall and the small tongue cut away from the wall side.
The largest area recommended is 8 x 10 meters (width x length). Larger areas should be divided with expansion joints. Expansion joints should also be made for doorways in rooms and, for example, between the living room and a long hallway, and covered with a joint strip or threshold. The strips must not prevent the natural movement of the parquet. Larger areas with no extension gaps will cause problems (more than usual gaps, noice etc.) when the wood floor naturally expands and contracts as the moisture content of the room varies with the weather. Problems caused by insufficient expansion gaps are not covered by warranty. 

IMPORTANT: Proceed with a visual inspection of the strips before installation. The warranty does not extend to cover the flooring after installation against defects present at the time of the installation. Once installed, any board is considered accepted by the installer and the owner, even if the owner is absent at the time of installation.

Before isntallation: The evenness of the subfloor must be checked before installation. The maximum permissible evenness deviation is +/-3 mm over a 2-meter measurement distance. Larger unevenness should be grinded/leveled using methods suitable for the subfloor.
Before laying on concrete, gypsum, or similar subfloor the moisture content must be controlled in accordance to Finnish building code. The moisture content must be measured as described in instruction RT103333 by a certified moisture controller. The moisture content must not exceed the limits specified by applicable regulations and must not also exceed 85 % RH in the measuring depth and 75 % RH in the surface part (0,4 x measuring depth and up) of the subfloor.

1. Laying of the floor should commence by placing the underlay material on top of the damp proof membrane [as necessary eg. on concrete subfloors] The membrane, such as 0.2 mm polyethylene, should be placed beneath the underlay with a 20cm overlap at any joints and these should then be taped. The underlay itself must fit flush, not overlapped.
On wood subfloor we do not recommend using plastic films under the parquet unless specified in the plans by the chief engineer of the building project. 

2. The first row of floorboards should be laid with the lock tongue facing the wall.

3. Along the shorter edges the panels should be joined by sliding the profiled (lock) elements of the next board at about a 30 degrees angle. By lowering the board into a horizontal position the lock is engaged. You may use the hammer and block on the panel from the short edge to secure the lock completely

4. When the first row has been assembled, it should be placed along the wall with 10-15 mm gaps on the 3 sides, using wooden wedges or waste pieces of the parquet.

5. The next row should be started using the length remaining from the previous row provided it is longer than 50 cm. If the off-cut is shorter than 50 cm – then a new parquet panel should be cut into half and 1 of the pieces should be used to start the row. Please ensure that short – edge joints are placed at a minimum distance of 50 cm away from each other in adjacent rows.

6. There are 2 ways to lay Uniclic parquet. We recommend the method described under 6B.

6.A Slightly lift the edge of the parquet panel and insert the tongue into the groove of the previous row and press it together so that there is no gap between them, and then press down to the floor until the boards are locked. You may need to use the hammer and block to fix the panel up tight to the previous row. The next board should be placed the same way leaving 5-7 mm distance between the short edges. Then the short edges need to be locked using the hammer and block and the wooden wedges applied at the end of the completed rows.

6.B Assemble the 1st row of parquet as described in point 2 above (laying the first row). When this row has been assembled completely allowing for expansion gaps etc. as described in method ‘A’, the whole row is inserted into the groove of the 1st row and then pressed down slowly until the lock engages. Using the hammer and block the whole length can be pushed up tight to the previous row.

7. The exercise is then repeated until only one row remains to be fitted.

8. The last row of parquet boards should be measured carefully as it is essential that, as previously described, an expansion gap is left all the way around the perimeter of the laid floor. If necessary, it should be cut to achieve correct width. Select an area to comment on

9. A gap of 10-15 mm wide should be left and the final row tightly pressed to the penultimate row using wooden wedges or hooks.

10. When the flooring has been completely laid, the wedges should be removed. The last task is to conceal the expansion gap and this can be achieved by any number of timber profiles available. The chosen profile should be fixed to the wall and NOT fixed to the parquet floor otherwise it would prohibit the natural slight movement inherent in any timber construction.
