Leadax Original Flashing Installation Instructions
Overview
- Leadax Original Flashing is installed and formed in a similar way to traditional lead flashing.
- Use your hands to pre-form Leadax Original flashing and the Leadax Dresser or Steel Pressure Roller to mold it into place.
- Temperature changes have little or no effect on the expansion or contraction of the product.
Roofing Materials
- Leadax Original flashing is suitable with all types of roofing materials (EPDM, bitumen, plastics and metals), only use Leadax High-Tack Sealant for fixation (not hot air)
- Leadax Original flashing can be used on all lead code 5 applications.
- For flat and low-slope roofs, seal edges and seams with Leadax High-Tack Sealant.
Preparation
- The ideal installation temperature is from 41°F (5 °C) and rising. Leadax Original flashing can be installed in temperatures as low as -4°F (-20°C), however forming Leadax Original flashing could be more difficult and require additional time.
- Ensure surface is dry and free of grease and dust before applying Leadax Original flashing.
Installation
- Installs up to 19.7ft (6m) without needing an overlap.
- Overlaps must be a minimum of 3.1” (80mm) and sealed with hot air or Leadax High-Tack Sealant.
- The recommended welding temperature is 800°F (425°C), depending on the ambient temperature. Use the Leadax steel pressure roller to press down the welding seam.
- In areas frequently exposed to wind, Leadax Original flashing can be secured using Leadax High-Tack Sealant.
- When molded or used as a facing material, it is recommended to secure with Leadax High-Tack Sealant.
- Use Leadax High-Tack Sealant to seal off any edges and seams.
- After application, remove the protective film from the face and reverse.

1. Install VaproShield WRB/Air Barrier membrane according to installation instructions. Pictured: WrapShield SA WRB/Air Barrier.
2. Place VaproMat horizontally against exterior wall, filter fabric side out. The drainage matrix should face the building interior. Starting at the bottom of the wall, position the first piece of VaproMat at the bottom edge of the stone where the weep screed is located (weep screed installed by others).
3. Mechanically fasten Vapromat approx. 2” down from the top edge with stainless steel (SS) staples. Continue securing VaproMat every 24”. Remaining VaproMat material will be held in place by stone lathing fasteners.
4. Vertical seams of VaproMat drainage matrix butt together and do not overlap.
5. Horizontal seams of the drainage matrix butt together.
6. Overlap the 2” selvage edge in shingle fashion. Secure every 24” with SS staples.
6. Trim VaproMat around all penetrations, windows and doors.
8. Install expanded metal lath over the VaproMat according to the manufacturers’ recommendations. Consult the Adhered Stone Manufacturers Stone Guidelines. All lath including weep screeds are installed “proud” or over the VaproMat material.
9. Apply thin-set stone according to manufacturers’ recommendations. Guidelines should include a weep method for ventilation and drainage as recommended.
