Stucco is one of the most popular and versatile exterior home treatments. You can apply it as glass smooth or popcorn bumpy and in many different colors. Although the three-step process is not for everyone, it can be accomplished with some knowledge and practice.

Facts about Stucco

Stucco has been around since ancient Rome. However, the original ingredients of stucco, which included animal blood, urine, eggs, and rye whiskey have undergone a major overhaul. Stucco is now made from Portland cement, hydrated limestone, sand, and water.

Where to apply stucco?

Stucco can adhere to any type of masonry as long as it isn’t painted or sealed to prevent it from absorbing water. You can also apply it to wood, regardless of whether it’s painted or not. However, you will need to first attach a lath, which is a strong metal mesh.

Get your tools and supplies.

You will need 15-pound roofing felt, paper-backed lath, metal cutters, nail guns, and nails that are appropriate for your walls if you apply stucco to masonry walls. A large bucket or tub is necessary to mix the stucco, as well as the tools and equipment to apply it.

To apply scratch or base coat, the first tool is a large flat trowel. The second tool is the scratcher. It looks almost like a wide comb. The second is the double-handled darby. This is a long, thin trowel that smooths the coat. You will be in need of a trowel and a hawk. The hawk is similar to an artist’s palette. You can use it to spread small amounts of stucco and then make any final coat designs. To ensure the stucco doesn’t dry before covering the entire wall, it is a good idea to have several people to help you.

Prepare the Surface

Use a sturdy brush or mop to clean your surfaces. A power washer can be used as long as your exterior treatment is adequate to handle it without causing damage. If necessary, patch any cracks. You must dampen stucco walls with a mister, whether they are stucco to brick, cement blocks, or existing stucco walls.

Apply lath to the wall if you are applying stucco to a wooden or painted surface. You don’t have to attach roofing felt before you can use a paper-backed, 17-gauge, self-furred lath. Take care to measure and then use your circular saw or metal shears to cut the lath to fit large panels. Start on one side, slowly moving to the other. Attach the lath to the wall using the proper nails at 18 inches intervals.

Use the Stucco

Follow the manufacturer’s instructions when mixing your stucco. Make small batches to ensure that the stucco doesn’t dry out or harden. Spread the stucco onto the lath by wiping it with a 3/8-inch thickness. Drag the scratcher horizontally across the wall once it is completely covered. This will make the next coat stick better.
