Product Description:

Hydrawood is unique, moisture resistant composite real timber flooring that can be laid on virtually any base without fear of swelling or delaminating.


Hydrawood can be used for commercial and domestic flooring applications inclusive of kitchens, bathrooms and areas where moisture could be a problem.

Hydrawood can be laid directly to cured concrete floors negating the need for a moisture proof membrane or moisture barrier.**

Hydrawood can be laid directly to MDF, particle board, wood or other cellulose composite flooring.

Note: Hydrawood is non structural and is recommended only as overlay flooring.


Sub-floor, must be dry, clean and free of dust.

Sub-floors must be flat to 3mm per 3m radius. If sub-floor prep work is required, “hills” should be sanded or ground down and “valleys” filled with a self leveling compound.

General Points:

As part of the sub-floor preparation, it is recommended that existing skirtings and architraves be removed to ensure a neat finish. These can be put back at completion. To avoid difficult scribe cuts, it is recommended to undercut door jambs by placing a piece of Hydrawood on the sub-floor as a height guide for hand saw cutting.


Gluing down Hydrawood to all sub-floors is recommended. To float the floor negates the unique water qualities. Gluing also reduces the footfall noise factor often associated with floating floors.

Recommended adhesive is
Selleys Direct Stick for concrete and timber floors.

For gluing / sealing tongue and groove, use Unika Lock seal. In addition to gluing, lock seal also is completely waterproof and is recommended on all joints where excess water is present.

Hydrawood can be cut using any traditional saw, saw blade or plane. In addition to a good saw, it is recommended that the following tools also be available.

Tapping Block: Use a hardwood block or polypropalene strip no less than 400mm width approx 500mm.

Pull Iron: Notched trowel for adhesive (3mm).



Hand Saw: Utilise for undercutting.

Jig Saw

Small Plane

Common Sense

Preparatory Installation:

Hydrawood should be glued to the sub-floor. The following methods are recommended.

For small areas (under 5 m2) Apply Sellys direct stick LF to the back of the board using the application gun to apply a 6mm bead of glue  across the full length and width of the board.

Always recommended and for larger areas  use Selleys Direct stick and trowel the direct stick to the sub-floor using a 3mm notched trowel. When laying in this manner only apply the glue to cover a maximum of four panels at a time to avoid glue contamination.

IMPORTANT: If glue gets on the prefinished surface, remove immediately with liquid nails direct stick remover, turps or an approved glue remover. Once glue is set it cannot be removed.

Always follow and adhere to the manufacturers' instructions. Hydrawood will not accept any liability for the misuse or poor application of adhesive.

Measure the width of the room being laid and calculate the width of the final board.  We recommend that the first and last boards be the same width to avoid a narrow last board.

When cutting boards using a circular saw or jigsaw, place boards face down and cut slowly and carefully to avoid chipping the edges.

If possible, lay panels parallel to light source.

Hydrawood is unique, in that minimal expansion and contraction occurs due to moisture, humidity and temperature variations. An minimal expansion gap of 2mm is recommended, be sure not to jam boards tight against fixed structures.

Position the boards but just before pushing two boards together leave a 5mm gap and fill with Unika Lock seal. Immediately tap / push boards together, excess Lock Seal should squeeze out of the seam, allow 5 mins to dry, then peel off overfill.

Install the first row with the groove facing the wall. The subsequent rows are installed, (side and end glued with Lock seal) with a hammer and tapping block.

Tapping block should be used gently against the tongue only. Do not tap on groove side as this can cause damage. Stagger all joins 400mm minimum is required between end joints.

It is best if the first three rows are installed simultaneously to reduce racking and to create a firm platform to work to. From then on lay one row at a time.

lnstalling the last row. Most often the last row will not fit. When this occurs, follow this simple procedure.

(a) Lay a row of boards, unglued, tongue to wall directly ontop of the last row.

(b) Take a short piece of Hydrawood with face down and tongue side to wall.

(c) Draw a line with a pencil along the row moving down the wall. The resulting line gives the proper width for the last row which, when cut can be wedged in with a pull iron or pinch bar.

Keep off floor for 12 hours to allow adhesive to set.

Finally replace all skirtings and trims.


Take your time - plan properly.

Ensure the floor is flat (within 3mm over a 3 metre radius) clean and dry.

Do not install over sub-floors with visible defects.
