It's tough to match the texture found on a stucco wall. We'll show you the steps it takes to make a repair look seamless.

On a wood-sheathed stucco wall, the sheathing is covered with roofing felt, then wire lath is nailed over the felt. Two or three layers of stucco are applied over the lath. On a masonry wall, stucco is typically applied directly with no lath.

Before patching a small area, press hard with your palm against the surrounding wall. Wherever you find sponginess, the stucco has disengaged from the wall and should be removed and replaced.

Getting a stucco patch to blend with its surroundings is more difficult than it may first appear. However, by experimenting with various tools, you can likely discover how to apply a texture that comes close.

What You Need

  • Caulking gun
  • Hammer
  • Cold chisel
  • wire brush
  • Lineman's pliers
  • Tin snips
  • Putty knife
  • Old can opener
  • Detail scraper
  • Masonry brush
  • Magnesium float or flat trowel
  • Scarifying tool
  • Paint roller
  • Wheelbarrow or trough
  • Masonry hoe,
  • Ladder or scaffolding
  • Stucco caulk or exterior caulk
  • Stucco patch
  • Stucco mix (basecoat and finish)
  • Roofing felt
  • Stucco lath
  • Roofing nails

What if you Need to Texture Your Patch?

Start with a basically smooth wall that is at the same thickness as the surrounding surfaces. Use a masonry brush or whisk broom to etch swirls, straight lines, or a pattern of alternating straight lines. You may need to periodically rinse the brush in a bucket of water.

To make a series of scallops, use a triangular trowel, sculpting with a semicircular motion.

To produce a spatter texture, dip a brush in a bucket of fairly wet stucco mix and flick at the wall by tapping the brush against a small scrap of wood.

To create a knockdown texture, start with peaks created by pulling back, and gently smooth the surface with a trowel.

Patching Small Holes

Step 1: Clean Hole

Tap with a hammer and chisel to remove any loose stucco. Use a wire brush, then a wet bristle brush, to clean out dust and debris.

Step 2: Attach Mesh

If needed, nail in place a new piece of mesh. Dampen the area with a wet rag shortly before applying the patch.

Step 4: Apply Stucco

Use a putty knife or trowel to apply a ready-mix stucco patch. It may take two or three layers to fill the hole. Allow each layer to dry before applying the next.

Step 4: Add Texture

When you reach the last layer, match the texture. Here, a brush is used in a sweeping, semicircular motion.

Repairing Cracks

Step 1: Widen Crack

Use an old puncture can opener or a detail paint scraper to dig out and widen the crack. Work to make the innermost part of the crack wider than the surface crack.

Step 2: Fill Crack

Apply stucco or mortar caulk, both of which have a grainy texture that blends with a stucco wall. Or to seal but not texture the crack, use regular exterior caulk.
