A trowel and a roller are both tools used for wall texturing, but they differ significantly in application, finish, and technique.
**Trowel:**
- **Application**: A trowel is a flat, handheld tool used to apply and spread plaster or joint compound on walls. It requires skill and precision to achieve the desired texture.
- **Finish**: Trowels can create a variety of textures, such as knockdown, Venetian plaster, or skip trowel. The finish is often more intricate and can be customized by varying the pressure, angle, and movement.
- **Technique**: Using a trowel involves spreading the compound in layers, often requiring multiple passes to achieve the desired effect. It allows for more control over the texture's depth and pattern.
- **Skill Level**: Troweling is generally more labor-intensive and requires experience to master, making it suitable for more detailed and artistic finishes.
**Roller:**
- **Application**: A roller is a cylindrical tool with a textured cover that is rolled over the wall to apply texture. It is typically used with pre-mixed texture compounds.
- **Finish**: Rollers produce more uniform and consistent textures, such as orange peel or stipple. The texture depends on the roller cover's design and material.
- **Technique**: Rolling is faster and easier, involving dipping the roller in the compound and applying it in a consistent motion. It is ideal for covering large areas quickly.
- **Skill Level**: Using a roller is more straightforward and requires less skill, making it accessible for DIY projects and beginners.
In summary, trowels offer more customization and intricate textures, while rollers provide speed and uniformity, suitable for large-scale applications.
