For optimal results when using Baines Masonry blocks, it is crucial to follow specific guidelines. Firstly, Baines Masonry blocks should be laid dry to minimize subsequent shrinkage. Additionally, it is important to keep mortar off the face of the blocks and clean off any droppings as work progresses, before the mortar sets. Whenever possible, avoid cleaning down with acid. A comprehensive guide to cleaning concrete masonry is available at Baines Masonry, or you can find full technical details on the Concrete Masonry Association website at www.cmaa.com.au.
When ordering, ensure you purchase enough product to complete the project at once to avoid batch variations. Concrete masonry blocks behave differently from clay bricks in terms of moisture movement and temperature changes. To prevent cracks in walls, assuming sound foundations are provided, use control joints, bond beams, and/or joint reinforcement correctly. The rules for using these elements are detailed in Australian Standard 3700-2011.
