HOW TO GET THE BEST RESULTS FROM BAINES MASONRY’S BLOCKS
DO NOT WET BLOCKS
Baines Masonry’s blocks should be dry when laid in the wall to minimise subsequent shrinkage.
CLEANING CONCRETE MASONRY
Keep mortar off the face of the blocks. Clean off droppings as work progresses and before mortar sets.
Cleaning down with acid should be avoided whenever possible.
A guide to cleaning concrete masonry is available at Baines Masonry or full technical details are available from the Concrete Masonry Association web site - www.cmaa.com.au
COLOUR
Care should be taken to order enough product to complete the project at the same time to avoid the possibility of batch variations.
CONTROL OF SHRINKAGE CRACKING
Concrete Masonry’s blocks behave differently to clay brick in regard to moisture movement and temperature changes.
Assuming sound foundations are provided, cracks in walls can be avoided by the correct use of control joints, bond beams and/or joint reinforcement.
Rules for the use of these elements are contained in Australian Standard 3700-2011
