Stucco is a building material made of aggregate, binder, and water that is applied wet and hardens into a solid surface. It is used to cover exteriors of buildings. The process of applying stucco involves first attaching lath and corner beads, then applying a scratch coat to embed the lath followed by a skim coat to smooth the surface and optional texture coat. Tools used include a hawk to hold the stucco and trowel to apply it in layers, scratching the first coat for texture before finishing with subsequent coats.

2. WHAT IS STUCCO?
• Stucco is a material made of an aggregate, a binder,
and water. Stucco is applied wet and hardens to a
very dense solid. It is used as decorative coating for
walls and ceilings. Stucco may be used to cover less
visually appealing construction materials such as
concrete, block, or clay brick and adobe.

3. TOOLS USED IN STUCCO WORK
• Hawk-The hawk is the palette or square with which you hold
your plaster.
!
• Trowel- the trowel is what you use to apply the plaster on the
wall

4. First you place the felt, (black paper), then the wire lath, then the corner beads
on corners and around doors and windows.

5. WHAT IS “LATH”?
• Lath is a wire mesh, typically with a paper
backing, that is applied to a wood or metal
framework as matrix over which stucco is
applied:
Lath
Corner bead

8. FIRST LAYER OF STUCCO:
SCRATCH COAT
• Scratch Coat.The purpose of the
first base coat, the scratch coat, is to
embed the metal lath and provide a
base for the skim coat.The scratch
coat gets its name from the fact that
it is physically scratched with
horizontal marks.These scratches
create texture, so that the skim coat
can stick to it.

9. HOWTHE SCRATCH COAT IS
DONE
• Once a full coat of stucco is
applied, use a broom to
create texture.

10. SCRATCH COAT AROUND WINDOW
• Corner Bead Around the window:
• Putting scratch coat around the window.

11. THE SECOND COAT:
• Skim Coat. The Skim Coat
is used to finish the wall, so
that it is smooth, and even.

12. THE FINAL COAT:
• Texture Coat. This coat is
optional, depending on the
desired look.The texture
coat adds texture and
dimension.
