Intrim VJ Board Pro sheets must be delivered to a building site after lock up stage, including all external windows and doors installed, fully roofed and external cladding completed, at least 2 days prior to installation. They should be stored within the building close to where they are to be finally fixed to minimise the impact of the surrounding elements including moisture content, and in order for the sheets to acclimatise.
It is preferable to lie them flat in a low traffic area for their safety with the top sheet placed upside down to keep the top sheet clean.
If sheeting both ceilings and walls, it is best to fix the ceiling sheets first. This will then set the sheet position for the end walls – it looks best if the ceiling grooves line up with the wall grooves.
Before you begin to install your initial wall or ceiling sheet, you need to plan what Intrim corner mouldings and installation method you intend to use to complete your project.
When sheeting the walls, it is common practice to start installing your initial sheet at an internal or external corner and work around the room from that point.
|Tools and Equipment||Framing Requirements|
|Measuring tape or folding rule||Walls:
|Handsaw or an electric circular saw|
|Hand or electric planer|
|Bubble or laser level|
|Intrim dripless caulking gun|
|Intrim Intense Hold adhesive|
|PVA Wood glue|
|Fixing gun or hammer|
|38mm long fixing nails or screws|
|Safety glasses or protective eyewear|
You may use a handsaw or an electric circular saw for cutting Intrim VJ Board Pro wall sheets. We recommend that the rear face of the sheet is positioned in a downward direction when using a handsaw, and the rear face of the sheet is positioned in an upward direction when using an electric circular saw, to minimise chip out, and form a neater finish to the cut edge.

When completing Intrim VJ Pro Board in ceiling or wall applications, there are several alternatives to choose from. Below are some typical details of our recommended Intrim moulding alternatives for completing installation of corners and joining ends of sheets. We can help you choose mouldings that best suit your application.
|Finishing an Internal Corner||Finishing an External Corner|
Scribe the second sheet so that it butts neatly up to the existing sheet.
|Method 1 — Corner Mould:
Trim the first sheet off level with the outside edge of the corner stud. Start the next sheet level with the outside edge of the trimmed sheet. Cover the join with an external corner timber moulding.
Butt-join the corner sheets (leaving a 3-5mm expansion gap) and fit a suitable moulding (e.g. square DAR, scotia, ovolo or quad) to cover any gap between the corner sheets.
It is good practice to always study and measure the walls in a room before commencing the installation to minimise waste.
|Method 2 — Butt joint:
|Method 3 — Mitre joint:
We highly recommend for your safety that you follow the below steps when installing and working with Intrim VJ Board Pro:
It is difficult to achieve a good result when butt-joining wall or ceiling sheets as expansion and contraction over time will inevitably crack the join.
We recommend 2 options:
An acrylic sealer-undercoat should be applied as the base coat if purchasing or using unprimed sheets.
The back of my sheets are raw, do I need to prime them?
Only if the sheets are likely to be exposed to moisture, e.g.
If the wall contains doorways or windows that are more than 1210mm wide, you can sometimes save material by starting to sheet at one edge of the opening; i.e. you can avoid cutting a large hole out of a sheet.
To fill in heads above doorways and floor-length windows less than 1210mm wide, you can use off-cuts, rather than cut large holes out of a full sheet. This is done using an off-cut and joining this to the v-groove of the next full sheet.
NOTE: The window and door head sheets must be installed as you go, otherwise you may not end up with a gap that is a full number of ‘boards’ wide. You will need to cut to the centre of the v-groove and router a groove to allow to install the tongue in the new join.
When you have finished one wall, you can use the off-cut from the last sheet to start the next wall if off-cut is large enough to be practical.
The Intrim VJ Board Pro tongue can be removed by pulling from one end of tongue using pliers. The tongue is interchangeable and may be used on either side of the sheet.
