Correct Selection and Mixing of Mortar for Brick and Block Laying.

Here’s some shocking information about bricklaying and illegal substances that not many people know.

Every day on Australian building sites, bricks and blocks are being laid with mortar additives that are not in compliance with the Australian Masonry Standards and industry best practice.

In fact these substances are banned. And Its actually worse than tha.

Most brickies and their labourers are ignorant about their huge mistake as these substances massively reduce the structural integrity and lifespan of the buildings.

 What we are talking about here is the use of Coca Cola and other sugar based drinks, Palmolive and other dishwashing liquid and high clay content “Brickies Sand” all added to the mortar mix to make it workable. And here’s why they do it.

 Clean sand and cement on its own is really tough to work with. The illegal substances are added to make the mortar soft and fluffy and easy to work with. This means the brickie can lay more bricks in a day and get paid more.

 And… There is another big problem…. the most junior person on the site, the brickies labourer is in charge of making up the mix.

 Often inexperienced and completely ignorant of the Australian Standards or how important the mortar is for the strength and life span of the building.

Even when they do know and care, they are told by their brickie boss to “Do what your told or find another job”

 So here’s the solution …. To this huge and complex problem and the widespread use of illegal substances used in mortar. 

1: Get educated about why mortar bond strength is so important

2: Understand and build to the Australian Standard

3: Specify a mortar additive that increases bond strength

4: Specifically mention that you do not want any illegal and banned substances added to your mortar mixes.

Metcell is a brand new product on the market. Its a methyl cellulose based water thickener that solves the problem of making a mortar mix that is easy to work with, compliant with the Australian Standards and increases bond strength and durability.
