Check every board carefully before installation for any manufacturing faults. We cannot consider any claims regarding product defects after installation.
Engineered flooring is not suitable for installations in wet rooms such as bathrooms, saunas or in similar rooms where there is a regular flow of water.
A professional floor fitter should be used to install the product and a list of these can be found on www.cfa.org.uk or www.bwfa.co.uk failure to use a professional fitter could invalidate any warranty.
All sub floors must be prepared for installation in accordance with normal sub floor preparations procedures and accepted tolerances within the flooring industry. To BS8204-1.
Before installing engineered flooring there are the following points to consider:
Engineered flooring: installed as a floating flooring configuration can be installed on all sub floors, which meet the above described requirements. Here are some examples:
The sub floor surface temperature may never exceed 27°C. Electrical radiant sub floor heating systems installed as foil-heating element may be used only if the manufacturer of the heating element can ensure that the sub floor surface temperature is never above 27°C. If the sub floor temperature exceeds 27°C a barrier must be inserted under the floor in order to dissipate the heat and achieve the correct reading. A sub floor thermostat must be installed in order to control this temperature. The heating engineers installing the underfloor heating should provide evidence that the sub floor temperature is limited to 27°C.
Controlling the sub floor temperature should result in a surface wood floor temperature of around 24°C – 25°C and a room temperature of around 21°C. We do not recommend this temperature is exceeded at any time.
Due to the nature of the product gaps between boards can occur and small hairline cracks may appear in the veneers due to the use of the underfloor heating.
Please note the following rules for the different sub floor types:
Engineered / Solid Blocks (All sizes) – Glued to the sub floor
13 / 14 / 15mm thick engineered – Glued on the top of the groove and floated or glued to the sub floor up to a width of 240mm. Above 240mm glue to the sub floor only.
18 / 20 / 21mm thick engineered – Float / Glued / Secret Nail up to a width of 190mm. Above 190mm the only methods we recommend are to secret nail or glue to the sub floor.
Before starting the installation the engineered flooring has to be brought into the room where it will be installed or in a room with the same climate condition. The acclimatisation will be carried out as following:
Engineered flooring looks its best when the engineered flooring panels are installed parallel to the light coming in through the windows. The only required installation direction is if you install engineered flooring over floor board. In this case you have to install the engineered flooring at a 90° angle to the existing hardwood floor boards.
After determine the best layout of the flooring and the starting wall, measure the width of the room and divide it by the width of the engineered flooring panels to determine the number of rows and width of the last row. If the last row is determined to be less than 60mm wide, it should be adjusted by cutting the first row length wise.
Since engineered flooring is made of organic materials, it is subject to certain movement behaviours (shrinkage / expansion) due to changes in climate conditions. It is necessary to leave gaps of minimum 10mm for the expansion in all parts of the structure i.e. walls, door frames, stairs and around pipes etc. Any vertical obstructions.
Through the shrinkage and expansion behaviour of engineered flooring you have to install transition mouldings in the following areas.
Please ensure all wet trades including painting have finished and all moisture levels recorded as previously advised before commencing the installation.
Check all panels for possible damages / Defects. Ensure you understand the difference between the tongue and the groove on the panel. Begin installing the first row from the left hand corner of the room with both tongue sides of the panels pointing towards the wall. Place spacers between the edge of the flooring panel and the wall to provide the correct space for expansion. Connect the second panel to the first by indirectly tapped using a hammer and push block, thereby joining the boards’ headers. Mark the last panel in the first row to the required length (place tongue to tongue) and cut. start the second row with the off cut from the last panel of the first row. Always make sure the off cut is at least 500mm long. Start all subsequent rows with the off cut piece from the previous row. Connect the second row to the first by placing the interlocking end of the new panel at an angle to the previously installed panel and then lower it into a horizontal position to lock then indirectly tapped using hammer and push block, thereby joining the boards’ headers. Ensure all the short ends are staggered at least 500mm. It is vital to maintain a minimum of 500mm between the ends of the boards in the adjacent rows (staggered).
If you have a wooden doorjamb, we recommend undercutting the wooden doorjamb according to the thickness of the flooring plus the possible underlay. Install the flooring now underneath the doorjamb – leave the necessary expansion gaps. In the case of completing your installation underneath a doorjamb we recommend that you remove the locking part of the protruding groove of the pre-installed panel with a utility knife or a pocket plane. The newly laid panel can now be pushed horizontally over the groove of the previously laid panel. Use high quality wood glue on top of the tongue to secure the connection if you have a doorjamb which cannot be shortend e.g. metal doorjamb we recommend that you cover the expansion gaps with mouldings or fill them with elastic acrylic sealants.
After a correct installation of the flooring, install the transition mouldings as well as wall mouldings.
Covering the boards with any form of protection may result in the board sweating and colour running, so we recommend this is only done for short term use and not days at a time.
Use the recommended appropriate finish maintenance guidelines supplied by your dealer. All natural oiled and some UV oiled products should be re oiled / waxed after installation in order to provide extra protection and to seal the joints, please contact your local distributor for the recommended products.
