Calculate Brick Size: Measure 10 random bricks, calculate average length, and add joint thickness (3-4 mm). Use this as a reference for the facade. Tip: Mix bricks from multiple packs for consistency.
Calculate Course Size: Stack 10 bricks, divide total height by 10, and add joint thickness. Tip: Always mix bricks from different packs.
Choose Mortar: Use standard mortar for Zero® bricks as the special hole increases bonding strength. Tip: Ensure bricks are wind-dry before use.
Mortar Colour: Use darker mortar for shadow effects or matching mortar for a uniform look.
Tilt the Bricks: Tilt each brick from front to back to evenly spread mortar, avoiding excess on the front edges.
Damp Proofing: Place moisture-proof foil and XPS insulation between brick layers below ground to prevent rising moisture.
Provide a Vertical Dam: Use waterproof foil and draught strips between windows and brickwork to block water infiltration.
Use Closers: For mismatched wall lengths, use longer or equal-length bricks as closers for a seamless finish.
Joists and Lintels:
Visible: Place bricks on top of joists, adjusting window casements.
Hidden: Lay bricks upside down to maintain course measurements.
Expansion Joints:
Straight: 5 mm or 10 mm openings with foam cords and sealers.
Stepped: Guide with foil or foam for independent wall movement.
Garden/Freestanding Walls: Use an open cavity construction to prevent the see-through effect.
Flat Roofs: Lay the top layer of bricks with the mortar bed down for a flat substrate.
