How To Patch Stucco (with Pictures) - WikiHow

Primary tools List

• Trowel- primary tool for spreading cement on wall
• Hawk- tool used for holding cement mix in one hand while spreading the cement on the wall using the trowel with the other.
• Darby or 2x piece of wood- This is used to even the patch out with the rest of the wall.
• Margin trowel or pointed trowel- For placing cement in tight areas.
• Drill and beater- This is the easiest way to mix the cement. Improvise and you may not need an electrical drill and beater.
• Wash brush- For cleaning tools.
• Aviation snips- for cutting small pieces of metal lath
• Snips- for cutting large pieces of metal lath
• Scoop- Used to scoop the cement mix out of the bucket. Improvise to use anything else for the same purpose.
• Scratcher- This is used literally to scratch the stucco during the scratch coat. Anything may be used in its place for the same purpose.
• Hammer tacker (stapler)- This tool looks similar to a hammer. You load staples into the device and pound on things in order for a stapler to come out.
• hammer
• chisel
• Tape measure
• Chalk or other device that can be used for marking
• float (This looks like a trowel with a sponge on the side without the handle)
• 5 gallon (18.9 L) buckets (The more you have the easier the process will be. These will be used for mixing in, holding water, collecting garbage and debris, and hauling around tools.)

Other tools

• work clothes (this is a dirty process so don’t wear any clothes you plan on wearing out next Friday night)
• Dust mask
• Eye protection
• Work gloves

Materials

• Metal Lath
• Double D tar paper
• Nails
• dry cement mix (To simplify this guide, assumptions will be made that the user is using a premixed bag of cement made for stucco. These pre-mixed bags will often include the fibers in the mix. I recommend asking someone in the store you are buying the materials from to help you find the right mix.
• Staples
• rubber membrane- This stuff comes in rolls. One side is a white plastic film and the other side is a sticky black tar like material.
• fibers (If you buy a bag of cement with fibers then you do not need to buy additional fibers)
• bonding agent- This is a white liquid that looks just like milk. Ask a person at the place you purchase the materials to ensure you buy the right product.
• Water (a hose with a nozzle comes in handy for clean-up)
• covering materials (tarps, tape, poly, anything that will cover up an area that could get messy throughout the process)
