How to Install Catnic Coil Mesh?
The coil mesh is laid in strips between brick or block courses leaving approximately 25mm clearance from the faces of the work. Where coil mesh joins are required, ensure they overlap by at least 75mm.
The reinforcement is then simply embedded in the mortar for the next course.
In most instances, application every third course, for the full length of the wall, will be sufficient.
To reinforce brickwork at an opening, e. g. window or door, mesh should be installed to overlap part of the opening, and part of the solid wall.
Thinking of the width of the opening, lay the mesh approximately a quarter of the way across the opening. The mesh should lie the same distance again, across the solid wall.
Above windows or doors, install Catnic mesh for 2-3 courses, starting from the course above the lintel as shown below
