How to Replace a Stucco Weep Screed

A stucco wall that is damaged needs to be repaired as soon as possible. One step in the wall's repair involves replacing a damaged section of weep screed, a device that allows moisture collecting behind the stucco to drain away from the wall. To replace a weep screed, you first need to remove a small section of the stucco to expose the metal lath. The stucco material is adhered to this metal lath.

Tape measure
Felt-tip marker
Chalk line
Circular saw
Carbide blade
Sledgehammer
Pliers
Pry bar

Instructions

- 1
  Measure up from the bottom on one side of the wall 12 inches with the tape measure. Mark the location with a felt-tip marker. Repeat this step on the other side of the wall.
- 2
  Snap a chalk line on the marks you made on the wall in Step 1.
- 3
  Cut along the chalk line with the circular saw using a carbide blade. Adjust the depth of the saw to the thickness of the stucco material. You can also progress in 1/4-inch increments until you reach the metal lath.
- 4
  Tap on the bottom section of stucco with a sledgehammer to separate it from the metal lath. Repeat this process along the length of the wall.
- 5
  Remove any nails or staples that were used to secure the metal lath to the wall with the pliers. Lift the metal lath up to expose the weep screed.
- 6
  Remove the weep screed from the wall using the pry bar. Take the weep screed off and set it aside.
- 7
  Set the new piece of weep screed along the bottom of the wall and secure it with nails using a nail gun.
