A sand-float finish is a type of plaster finish that features a slightly grainy, textured surface achieved using sand and a float tool. It is widely used in both residential and commercial buildings due to its durability and aesthetic versatility.
The texture can vary from fine to coarse, depending on the size of the sand particles used and the technique applied during installation. This finish is particularly valued for its ability to conceal minor imperfections and provide a uniform, visually appealing surface. Click “different types of plastering” for more info.
What Is A Sand-Float Finish?
Definition And Characteristics
A sand-float finish is a stucco or plaster finish that is created by adding sand to the plaster mixture and applying it with a float tool. The result is a slightly rough yet consistent texture, which enhances both durability and appearance.
- Textured Surface – The finish has a slightly rough, sand-like feel.
- Versatile Appearance – It can be adjusted for a fine, medium, or coarse texture.
- Durability – Provides resistance to weathering and surface damage.
- Customisable Colour – Can be tinted or painted to match different aesthetics.
This finish is commonly used to enhance exterior and interior surfaces, providing a refined yet durable option for construction projects.
Materials Used In A Sand-Float Finish
A sand-float finish is made from a combination of:
- Cement-based or gypsum plaster – Acts as the primary binding agent.
- Sand – Determines the texture and contributes to the finish’s grainy appearance.
- Water – Ensures proper consistency for application.
- Lime – Improves workability and reduces cracking.
- Pigments (optional) – Added for custom colours.
The ratio of these materials influences the final texture, ensuring flexibility in design and application.
Application Process
The sand-float finish is applied using a series of steps:
- Surface Preparation: The surface must be cleaned, moistened, and primed to ensure good adhesion.
- Base Coat Application: A rough coat of stucco or plaster is applied.
- Texture Formation: A float tool is used to spread and create the desired texture.
- Curing: The finish is allowed to dry and harden properly to prevent cracking.
- Final Touches: The surface may be painted or sealed for added protection.
Each step is crucial in ensuring a long-lasting and visually appealing sand-float finish.

Frequently Asked Questions
What Is The Difference Between A Sand-Float Finish And A Smooth Finish?
A sand-float finish has a textured, grainy appearance created using sand and a float tool, while a smooth finish is polished and free from texture. The sand-float finish is preferred for its durability and ability to hide imperfections, whereas a smooth finish offers a sleek, modern look but requires more maintenance.
Can A Sand-Float Finish Be Applied To Any Surface?
A sand-float finish is commonly applied to stucco, plaster, and concrete surfaces. It may not adhere well to glossy or non-porous surfaces without proper preparation. For best results, a bonding agent or primer should be used on surfaces like drywall or metal.
How Long Does A Sand-Float Finish Last?
With proper application and maintenance, a sand-float finish can last 20–30 years or more. Its longevity depends on factors such as weather exposure, surface preparation, and the quality of materials used. Regular cleaning and occasional touch-ups can extend its lifespan further.
