Preparation:
- Install flashing and house wrap (e.g., Tyvek) per manufacturer’s instructions. Seal the exterior sheathing effectively.
- Ensure all surfaces are clean, dry, and structurally sound.
Panel Alignment & Attachment:
- Cut off the bottom alignment track of the panel to install a complete course of thin brick at the base.
- Begin at the bottom of an outside corner, aligning the panel flush with the corner.
- Work horizontally, leveling each panel.
- Cut panels vertically as needed to accommodate wall lengths.
- Use a level and corner thin brick to align continuous alignment track channels.
- Utilize the Panel+ tongue & groove system for continuous insulation and easy installation.
- Stagger or offset panels to prevent creating standing seams.
- For mechanically fastened method: Attach foam panel to sheathing using Old Mill washers and screws at least 1” into the main structure's framing.
- For fluid-applied method: Apply Old Mill Air & Water Barrier with a paint roller or spray system, allowing it to cure (1 hour dry to touch, 2 hours for recoat, 12 hours total at room temperature).
Thin Brick Application:
- Start from the top of the wall, installing corner bricks first.
- Apply a 3/8” bead of Old Mill adhesive to the back of the corner brick.
- Work inward from the corner, applying adhesive directly to the panel brick track.
- Run a single course of brick horizontally along the brick tracks of the panel.
- After the initial course is in place, use plumb lines to keep courses orderly.
- Cut bricks as necessary.
Grout Installation:
- Mix Type S mortar with water according to instructions for a smooth consistency.
- Apply mortar mix over joints, both horizontally and vertically.
- Allow mortar to set to a firm, pliable consistency.
- Use a joint tooler for embedding mortar into the joint up to 1/8” below the brick face.
- Brush joints with a stiff brush in diagonal strokes after the mortar sets, to remove excess.
Cleaning & Finishing
- Brush grout joints with a stiff bristle deck brush using diagonal strokes when grout becomes stiff, to remove excess grout from brick faces and joints.
- Clean brick as required after grout is cured, following the cleaning compound manufacturer's instructions.
- Rinse brick promptly and thoroughly with clean water.
- Use the appropriate cleaning solution 24 to 72 hours after grouting.
