Engineered Timber-Floating & Glue-down


Step       1:            PRE-INSTALLATION PROCEDURES:

Please handle, transport, and unload the flooring with care.  Flooring should be stored in a dry place, with at least a 100mm air space under cartons.  Flooring should not be delivered until the building has been closed in with windows and doors in place, and until cement work, plastering, painting, and all other materials are thoroughly dry. Acclimatize  the flooring for at least 48 hours (preferably 3-4 days) prior to installation  In addition, the heating or cooling system should be operating and controlled at 40°–60° for at least 48 hours before, during and maintained after installing.  Do not install in areas that are subject to extreme seasonal temperature changes where you cannot control the temperature. .  Due to the many different types of radiant heat floors, we do not recommend installing over this type of substrate.  


Step       2.            MOISTURE TEST:

Before installing over concrete or a wooden sub-floor, check the floor for moisture in several areas using an appropriate qualified commercial moisture meter.

The acceptable moisture level of Concrete sub floors should be no more than 3-5%, if the test is within the specified range, this also applies to engineered floors that are manufactured using ply-wood as its structure.

Engineered flooring is not to be confused with solid timber as engineered is dimensionally stable.


Step       3.            SUB-FLOOR PREPARATION:

ACCEPTABLE SUBFLOORSThe sub-floors must be structurally sound.

Note:  The sub-floor must be structurally sound and checked for moisture content. Movement and squeaks should be well fastened with ring nails or screws to the floor joists. If gluing the Floor down direct to the concrete then the sub-floor must be clean and free of paint. Wax, oil, paint and other debris must be removed; In addition it must be flat and level within 2mm inside a 3meter radius.  High spots must be sanded/ground flat and low spots must be filled with a leveling compound recommended by your dealer. On old or uneven wood floors, apply 15-20mm Plywood, glue & screw every 150mm to avoid squeaking & hollowness – gluing is essential if sub floor was uneven


Step       4.            BEFORE INSTALLATION:

Unpack & lay out the flooring where it is to be installed, that is, lay the boards down roughly as they will appear after installation, taking care to mix in a color pattern pleasing to the eye, Our quality control procedures at the factory ensure that very few, if any boards are defective when delivered to the consumer, remember that all natural flooring comes in a range of colors and shades, the Installer should inspect each plank at this time for finish and quality, check for damaged or defective boards if any are found these should be removed and returned to your supplier for exchange or you may choose to  fit these boards in areas out of site such as cupboards.




Use 3mm foam padding Underlay we suggest using TIMBERWALK Silent Step high density acoustic underlay, you can also install over sound deadening underlayment’s with this method. Apply a 3-4mm bead of PVA D3 CROSS LINKED ADHESIVE: NOTE WHEN INSTALLING TIMBERWALK BY FLOATING METHOD, THEN YOU MUST USE A D4 ADHESIVE: the glue must be placed on the upper top edge of the groove, both the long and short side of the boards MUST be glued, this is done by turning the board with the face pointing down, the glue is applied in the groove then the board is turned back and is ready to install. Use a tapping block if necessary to gently tap the boards into place, a tapping block can be made with a 150mm” piece of scrap timber flooring.  Remember to allow at least 10-15mm for expansion around the perimeter walls. Do not tap on the tongue or groove directly, as you will damage the floor.  Be sure to remove all excess glue as quickly as possible, as once it dries it may be more difficult to remove. You can use a watered damp cloth. when removing the D3-D4 glue.

NOTE:  Failing to use sufficient glue will cause movement & squeaking. 


Snake Or Zig Zag: this method is done by applying a continues bead of glue on the back of the floorboard, the bead must not be more than 100mm apart. The board is glued and then put in place by firmly pushing/moving the board in position which will  take up any unevenness in the sub floor, it is very important that sufficient adhesive is used at all times, if not, movement could occur resulting in drumming or squeakingBe sure to clean up any adhesive on the surface immediately, as once it dries, it may be very difficult to remove.  Always follow manufacturers’ instructions using their suggested adhesive and installation instructions for their adhesive warranty to be in effect. Remember to leave at least 10-15mm “expansion gap around the perimeter.  This method is suitable for ENGINEERED TIMBER


The adhesive is poured onto the sub floor/concrete in small amounts, a cup size is sufficient, then using a 3- 6mm notched trowel the adhesive is spread evenly over the sub floor, this must be done in small areas as the adhesive has a tendency of sinking, the board is then placed in position by firmly pushing/moving the board in place. Be sure to clean up any adhesive on the surface immediately, as once it dries, it may be very difficult to remove.  Always follow manufacturers’ instructions using their suggested adhesive and installation instructions for their adhesive warranty to be in effect. Remember to leave at least 10-15mm “expansion gap around the perimeter. This method is suitable for ENGINEERED TIMBER

NOTES: Timber flooring are a natural and environmentally friendly product take care to install this flooring correctly; taking all precautions suggested in this guideline, the flooring will give you many years of satisfaction.  Please note that it is always best to have your floor installed by a professional licensed floor installer even though it is possible to install yourself.  This is only a guideline regarding the installation of this flooringTIMBERWALK cannot be responsible for the installation under any circumstances, unless installed by an employee of TIMBERWALK or by a fully licensed installer


Usually you will want to orientate the boards with the major source of incoming light (windows) so that light is shining down the length of the boards, or install the floor  with the length of the room.


Blue masking tape, available from most hardware shops is ideal if you need to hold the boards in position, in most cases the floor does not require clamping


SKIRTING & SCOTIA’S:   Remove skirting if possible and undercut door jambs to insure a quality installations if the skirting’s are left on then you need to finish of using a Scotia trim

FINISHING THE JOB: Replace original skirting, or install matching skirting.  Install matching transitions as needed or recommended by your dealer.

INSTALLING OVER EXISTING TIMBER FLOORS:   Floating is the preferred method, installation must be in opposite direction to existing panels, the floor must be sound, level and without creaking or squeaking


VINYL TILES-LINO:           Floor cannot be glued down unless suitable floor preparation has been performed;    floating method can be applied on top of vinyl tiles using appropriate membrane

Concrete: Floating system or Glue-down method can be applied

RECOMMENDED AREAS: Timber flooring IS not RECOMMENDED to be installed in wet areas such as bathrooms (with tub/shower), wet rooms, outdoors, in direct sunlight, or areas that allow water to be carried in, unless you are very particular about the way you treat your floors such as rubber mats in bathroom then it is up to you, some people have been very successful with timber floors in these areas.

FOR CREATING A RANDOM EFFECT: To avoid creating a joint pattern in the floor, it is necessary to begin installation using starter boards. To create a starter board, cut the board at 2/3 the length.  Start with the 2/3 length, and then install the full lengths and continue across the room. Use the 1/3 length to start the next row and continue as above keeping at least a 250mm distance between the end joints. Cuts made at the opposite wall should be used for starter boards.  If necessary, use the pull straps -clamp at 1meter. Intervals to hold the planks firmly together.  Be sure to allow at least a 10-15mmexpansion gap around perimeter.

SEALING:            The floors come pre-finished in a factory environment, it is not necessary to apply additional sealing or waxes


  1. Read all instructions first: Get all your questions answered before you start installing the floor.
  2. Amount of needed: Buy enough flooring to equal at least 105%to 110% of the square meterage of your room, for waste allowance.
  3. Before installing, with closed boxes let flooring sit in room for 3 to 4 days to acclimatize to temperature and moisture. Run air conditioning or heat, as it will be in normal living conditions.
  4. Be aware of moisture problems: Moisture can ruin any floor. Always look out for potential moisture problems, especially in basements.
  5. Dealing with moisture before installation: If you have or suspect moisture problems, don’t install your floor yet. Contact a professional flooring installer to improve sub-floor to an acceptable level of moisture.
  6. Room/entryway preparation: Undercut door casings are much better than trying to scribe the flooring to fit there.
  7. Leave expansion gaps: Leave a 10-15mm space at each wall, beneath door jambs (these can also be scribed) and at transitions for expansion of flooring, skirting and Scotia’s will cover any gaps
  8. Tapping block: You can use a trimmed piece of flooring for this, or buy a pre-made tapping block. NEVER HIT FLOORING DIRECTLY AND BE CAREFUL NOT TO FRACTURE FLOOR EDGES.
  9. Old glue on the board can be removed using Methylated Spirits or Turps, gently wipe with a soft cloth

1) Bending or bowing of the boards in length direction. These boards might be a little harder to install, but will NOT be a problem after they are installed, or in the future.  They will lay flat WITH THE OTHER BOARDS

2)  Color Variations may occur as timber are natural products be sure to select the colors accordingly before installing.

NOTE: It is normal for all hardwood  floors to expand and contract with the seasons. This means that small gaps may form during low humidity conditions.   You can prevent this from happening by controlling the humidity year-round.   All floors will scratch and dent depending on your living conditions.
