A. Scope

 

Hydrawood Lining products can be fixed directly to Steel and also timber frame constructions.

​

Standard sheets are produced in white with one side GLOSS and the other side MATT finish 

 

Timber Framing

 

Studs must be placed at 600mm maximum centres for 1200 wide sheets and 450 wide centres for 900 wide sheets, with nogs and top and bottom plates at 1200mm maximum centres.

 

For ceilings, battens should be spaced at 400mm minimum centres

Timber support faces must be straight, flush, in alignment and the bonded surfaces must be dry and clean.

Moisture content of support surfaces must be less than 18% moisture content and must be in accordance with NZS 3604.

Hydrawood Lining products can be affixed directly to existing wall linings such as plasterboard.

Stainless steel screws must be used when fixing to and or through Hydrapanel.

 

Lined Walls and ceilings

 

Surfaces, such as plasterboard must be flat, sound and suitably fixed

Concrete, Masonry or brick walls and ceilings

Ensure concrete, masonry is dry and seal if necessary

Timber battens must be fixed as follows;

For 1200mm panels, battens are spaced horizontally and vertically at 600mm centres

For 900mm panels, battens are spaced horizontally at 600mm and vertically at 450 centres

For ceilings, battens are spaced at 400mm centres

Battens / strapping must have DPC between the timber and concrete surface

 

Shower linings

 

Old shower linings must be removed, framing and plumbing must be inspected to ensure items are fit for covering

 

 

B. Hydrapanel Aluminium Jointers

 

1. End Cap

Use to finish the end of a panel.

Also used as a top cap and bottom cap to the panels as required

 

2. Standard H Jointer

Use to join sheets on a flat surface 

Can also be used as an end cap where a negative detail is required

 

3. Mini H Jointer

Use to join sheets on a flat surface with a minimum profile cover

 

4. Internal Corner

Use to join sheets where sheets intersect at an internal corner junction

 

5. External Corner

Use to join sheets and to protect the edges at an external corner junction

 

6. Jointer notes

 

• The above jointers are designed for use with the Hydrapanel 7.6mm Lining

• Generic 7.5mm Jointers are available from Bunning’s for use with Hydrapanel Lining 

 

Fixing with Adhesives

 

Hydrawood Lining panels are easy to install using Selleys Armourflex FC Adhesive, Gorilla Fix All High Tack, Wurth PUR construction adhesive Rapid.

Hydrawood Lining panels can be installed using Aluminium or plastic jointers.

Hydrawood Linings can also be installed edge to edge with a silicon joint between the panels.

Hydrawood Linings can be installed combined with double sided tape to be used to hold the sheets in place while the adhesive sets or the sheet can be braced for approx 24 hours to allow for full adhesive cure and adhesion.

When using tape with jointing strips, do not apply tape on the stud where the jointer is located, as this will not allow for the Hydrawood lining sheet to slide into the jointer section.

Construction adhesives should be used in accordance with this guide.

 

Recommended adhesives;

​​

• Selleys 650FC  ( formerly ARMOURFLEX FC )

• Gorilla FIX ALL HIGH TACK

• Wurth PUR CONSTRUCTION ADHESIVE RAPID

 

INSTALLATION PROCESS

Materials Required

 

• Selleys Armourflex adhesive

• Hydrapanel double sided foam tape or similar

• Selleys Ply cleaning wipes

• Screws / nails

• Silicone sealant and masking tape

• Edge sealer **

• Lint free cloths

• Packing blocks – minimum 10mm

 

 

Tools Required

 

• Cartridge Gun

• Sharp blade knife

• Hand Saw

• Battery or power drill

• Level

• Sanding block

 

Preparation

 

• Check all walls and ceiling and floor intersections are square

• Check framing is dry, all timber and sheet surfaces are clean and free of contaminates 

• Check framing is straight, flat and level across the face surface

• Measure and mark sheet positions to centres of corresponding framing, if using jointers allow tolerances for the panels to fit easily between

• We recommend using full sheets in the centre and cut sheets at wall junctions

• Sheets are gloss on one side and matt on the other - gloss side has the Hydrapanel label.

 

Cut and prepare sheets

 

Measure panel sizes from top and bottom of the wall to determine panel width

• Using a straight edge, cut the panels to suit, using either a table saw, circular saw, hand saw or router

• Remove the protective plastic film 60mm from each edge, DO NOT remove all of the film until the panels are completely installed.

• Smooth finish the edges of the sheets with a planer or a block with 200 grit sandpaper

• Mark and cut out for penetrations

• Seal edges of all penetrations with Selleys wet area silicon sealant

 

Installation using adhesive with standard  8mm* jointers 

(*Suitable for Hydrapanel lining only)

 

• Ensure that you have a clean and prepared surface to work with.

• Wipe down the timber/steel framing that you are going to overlay with a solvent based Cleaner. Ensure that you use plenty of clean lint free cloths.

• Wait for Cleaner to completely dry.

• Fix the first jointer to the stud 

• Fix second jointer to Right hand side of first sheet

• Use sealant in jointers if using in wet areas 

• Apply a continuous bead of Selleys Armour Flex FC Adhesive 5mm x 5mm .

• Wipe down the corresponding reverse side of the Hydrawood Lining (that surface that is going against the timber/steel framing or wall) with Cleaner. (Ensure that you use plenty of clean lint free cloths.)

• Fit the edge of the sheet into the jointer and press the panel against the adhesive on the framing whilst packing the sheet of the floor / base with 10mm packers.

• Roll or press firmly over all areas of the Framing or Wall to ensure that the adhesive is compressed to a point where the Hydrapanel™ is in full contact with the glue and Double Sided Tape.

• Screw or pin the jointer attached to the sheet to the corresponding timber frame.

• Repeat this process until finished.

• Leave finished Hydrapanel™ lined a full 24hours for the adhesive to cure before carrying out further work in the area/room being lined with Hydrapanel™

• Apply Selleys wet area silicone sealant to all penetration edges after sheets have been fixed

• Remove masking tape whilst the silicone is still wet. (do not touch the silicone with skin as this can promote mould growth)

• When installing in a 3 sided shower, fix the centre sheet with jointers attached to both sides of the sheet

• Double sided tape can also be used to hold the sheets in place while the glue dries ….. please note however that the use of tape will not allow the panel to be moved or slid into position, care must be taken if using tape that the panel is in position before it is pressed to the wall / stud

​

HELPFUL HINT - When screw fixing; use 6g x 30mm screws / pilot drill hole in Aluminium with 1/4 inch drill bit, this will allow the 6 guage screw to countersink and sit flush to the aluminium edge

 

Installation using adhesive and silicone joints

 

• Position Double Sided Tape to stud in centre position of the panel 

• Apply a continuous bead of Selleys Armour Flex Adhesive 5mm x 5mm to framing (positioned approx 25mm from the edge of the Double Sided Tape).

• Wipe down the corresponding reverse side position of the Hydrawood Lining (that surface that is going against the timber/steel framing or wall) with Solvent Cleaner. 

• Roll or press firmly over all areas of the Framing or Wall to ensure that the adhesive is compressed to a point where the Hydrapanel™ is in full contact with the Double Sided Tape, whilst packing the sheet of the floor / base with 10mm packers.

• Position corresponding sheets with a continuous joint of 3mm

• Hold sheets in place with Nail blocks (refer detail 2 )

• Repeat this process until finished

• Leave finished Hydrapanel™ lined a full 24hours for the adhesive to cure before carrying out further work in the area/room being lined with Hydrapanel™

• Once adhesive has cured, remove nail blocks

• Remove 60mm of the protective film from each edge of the panels

• Apply masking tape to the panel edges and apply silicone sealant to the gap between the panels

• Apply silicone sealant to all penetration edges after sheets have been fixed

• Remove masking tape whilst the silicone is still wet. (do not touch the silicone with skin as this can promote mould growth)
