Real stock, not a swatch. Blended products vary a little batch to batch, so treat these as a guide rather than an exact colour match.

What Adbri Grey Mortar suits
What can you use Adbri Grey Mortar for?
Bricklaying
The bag's first listed use. A small wall, a garden bed edge, a repair course.
Barbecues
Listed on the pack. Small, freestanding masonry where buying sand separately is more trouble than the job.
Letterboxes
A bag or two does the whole thing, and there is no leftover sand pile to deal with afterwards.
Repairs and repointing
When you need a small consistent batch today rather than a mix you have to proportion by shovel.
How many bags of grey mortar?
Count the bricks, not the metres
Mortar quantity follows the number of joints, which follows the number of bricks. A square metre of standard brickwork is a much better starting point than a square metre of anything else.
For small jobs it is quicker to bring the brick count to the counter and have somebody who does it daily tell you, than to work it out from a table.
| Job | Roughly | Worth knowing |
|---|---|---|
| A letterbox | One to two bags | Almost always less than people buy. |
| A barbecue | A few bags | Depends entirely on the design — bring a sketch. |
| A repair or repointing | One bag | Mix small. Mortar does not wait for you. |
| A wall of any size | Ask us | At some point sand and cement separately is cheaper. We will tell you where that point is. |
Water quantity is printed on the bag and it is the number that matters. Wet mortar burns skin and the burns are delayed, so people often do not notice at the time. The dry blend contains crystalline silica. Gloves, eye protection and a P2 mask, every time.
Adbri Grey Mortar in Perth
The coastal question, in Perth
M4 mortar is required in severe marine exposure, and a lot of the metropolitan area sits inside that band. It is the single most useful thing to check before buying a pre-mix for external brickwork.
Ask us, or ask your builder, and do it before the bags are in the car. It is a two minute conversation that saves a wall.
Why Adbri Grey Mortar
Why choose Adbri Grey Mortar?
Nothing to proportion
Shovel-counting is where small batches go wrong. This is the same mix every bag, which matters more on a repair than on a wall.
No sand to buy or store
A cubic metre of brickies sand is a big commitment for a letterbox. Two bags is not.
The class is printed on it
AS3700 M3, on the pack. You can point at it, which you cannot do with a site-mixed batch.
Grey, for most brick
If the brick is red, brown or dark, grey is almost always the right joint. Cream is for cream brick and reconstituted limestone.

Using Adbri Grey Mortar
How to use Adbri Grey Mortar
Work out how many bags first
Mortar goes further than people expect on a small job and nowhere near as far as they expect on a wall. Bring the brick count to the counter.
Add water to the bag's figure
The quantity is printed on the pack. Measure it rather than eyeball it — extra water buys workability and costs strength.
Mix small batches
Mortar has a working life. Mix what you will lay, not what you will still be looking at in an hour.
Keep it off your skin
Waterproof gloves and eye protection. Lime makes mortar more caustic, not less.
When to choose something else
When it is the wrong product
- It is an M3 mortar. AS 3700 asks for M4 in severe marine exposure — in practice within about a kilometre of the water, which catches a lot of Perth. For external brickwork near the coast, check the classification before you lay.
- It is a mortar, not a concrete. It bonds masonry together; it does not carry structural load and it is not a substitute for a concrete mix.
- Mortar is caustic wet and the burns it leaves are delayed, so a splash you ignored in the morning can be a chemical burn by evening.
- The dry blend contains crystalline silica. P2 mask while you tip the bag, and mix in the open air.
