The options for stucco finishes are vast. With basic skills you can create a wide variety. One of the easiest to get started with is the Sand float finish.
The process is demonstrated in this video from Wayne Previtti of East West concrete. Here are the steps he uses for a sand for a sponge sand finish is 3 steps:
- Spray the stucco.
- Trowel it to a smooth with as little troweling as possible.
- Rub the surface as it is setting up with a lightly moistened sponge.
Note the way he pulses the trigger on/off so that he can spray a 1/8 inch average final coating. Normally we say that the stucco sprayer has a range of 1/4″ tick to 1″ thick coatings. With this technique you can get a thinner average. Wayne reports that when using the sprayer he and one employee get as much work done as they used to do with 3-4 people.
Some additional interesting notes about this video. Since he is finishing Rastra ICF blocks, Wayne goes straight to the finishing coats without the traditional Brown and scratch coats. He uses the sprayer to finish ICF and Concrete block walls this way. With Styrofoam ICFs he is careful to power-wash any oxidation off the wall before he begins. He has also use the sprayer in thin shell structures for ferrocement.
Another good resource for stucco finish textures is the TSIB Technical Services and Information Bureau. They have a pictures page with many different finishes.
