Why builders care
The board is where a wet-area quote can quietly lose margin.
When tile, membrane and labour are already in the package, board cost can squeeze margin. Price MgO early, show a cleaner substrate number, and trial it on a small wet-area or balcony job first.
19mm board
Tongue-and-groove sheet for wet areas, balconies, renovations and joist floor systems.
Sample first
Sample pieces are available locally before the builder prices the full floor package.
Quote-ready count
Send drawings or floor area and we can help price sheet quantity and delivery.
Where MgO earns a place
Where this board fits.
Best for wet-area and balcony scopes where the builder wants a sharper substrate number, a sample in hand and a clear sheet count before quoting.
Bathrooms & laundries
For wet-area floor builds where the membrane system is priced separately.
Tiled balconies
A 19mm board option for balcony and tiled deck build-ups, subject to project approval.
Joist floors
19mm tongue-and-groove board for timber or steel joists up to 450mm centres.
Repeat renovations
Use one board profile across similar bathroom and laundry scopes.
Why quote an alternative?
Because the familiar option can still make the quote too tight.
When fibre cement, AAC or yellow tongue pushes the package up, check a 19mm MgO option before the client signs off.
Early comparison
A confirmed sheet count helps the client compare the substrate option early.
19mm selling point
A thicker 19mm board profile builders can put beside common 18mm retail boards during early pricing.
Local samples
Show the board before the first order.
Cleaner quote split
Keep board, membrane, adhesive and finish clearly scoped.

FAQ
Straight answers before you try it.
The questions builders ask before putting a new board into a real job.
Why try MgO if my current board works?
Because it can give the quote a cleaner board number before the floor build-up is locked. Start with a small wet-area or balcony job and compare the total package.
Where is it strongest as a sales offer?
Bathrooms, laundries, tiled balconies, joist floors and repeat renovation scopes where price, sample speed and a 19mm tongue-and-groove sheet matter.
Is it waterproof by itself?
No. It is the board under the system. Wet areas still need the nominated waterproofing membrane and tile or floor-finish build-up.
Can it replace yellow tongue, fibre cement or Hebel?
Only when the builder, designer or certifier accepts the build-up. Treat it as an option to price and check, not as an automatic swap for every floor.
What do I send for a quote today?
Send the suburb, area or drawings, application, joist spacing, finish and delivery timing. Heriton can price the sheets, sample and delivery.
Final pricing and use depend on current stock, quantity, delivery, accepted substrate, waterproofing, fixing and project approval.
