Concrete Finishes Types
Concrete Finishes Los AngelesThe most common form of concrete finishes is the smooth surface. This is achieved using screeds and towels. Once the concrete has been poured on forms, the technicians use a screen to even out the concrete surface. Screeds are composed of long pieces of wood or metal, which are then pushed and pulled across the surface. This technique removes excess concrete while filling in gaps on the surface.
Troweling or floating
They then push and pull it across the surface of the concrete. Power trowels are also available, although they are mainly used on large industrial and commercial applications, where hand trowels would be too tedious. When it comes to power trowels, you can either use the riding version or the walk behind version.
Broom finish concrete
A broom finish is applied to make the surface slip resistant. Once placement, leveling and concrete troweling are done, broom finish follows. After creating a smooth surface, the concrete installer drags a broom across the concrete surface.
This creates small ridges, which enhance traction and grip, especially when the surface. Surfaces that don’t have a broom finish are quite slippery and dangerous, especially when liquids are present.
Exposed aggregate concrete
The resulting surface is slip-resistant and attractive.
Apart from using normal concrete materials, you can also add other materials into the mix. The result is a unique look. Some of the materials that can be added into the mix include limestone, rose quartz, black or dark grey basalt, blue or red granite, sea shells and colored glass.
When adding these materials, avoid anything that contains iron, since it might stain the concrete. You should also seal the surface after curing to protect it from wear and tear.
Pigment coloring gives you a wide range of color choices, from browns, tans, greens, grays and blues. Once pigment coloring has been applied, keep the surface sealed throughout its lifetime to prevent water infiltration, which might lead to fading.
Concrete stain and Sealer
Similar to the application of concrete pigments, you can only obtain relatively subtle or non-bright color tones.
Water-based, commonly known as acrylic staining, gives a wider range of colors. However, water-based staining is prone to fading.
With acrylic staining, you can even obtain black and white colors. However, it does not stick on the concrete for long, and therefore, requires re-touching. Stains can be applied on any concrete, regardless of the age.
However, the colors tend to be more vibrant, when the staining is applied immediately after placing the concrete. Stain application is followed by concrete sealing to protect the surface.
Polished Concrete Los Angeles
The process of concrete polishing is done using concrete grinders. These grinders are usually outfitted with diamond abrasives. The grade of the abrasive will determine the result. During the polishing process, the surface is first stripped of any existing treatment, such as coatings or sealers. After that, all visible cracks are repaired. The polishing process then follows, using either a fine or coarse grade.
Chemical hardeners are also applied somewhere during the process, to provide a future shield against water infiltration. Finer abrasives are then applied, until the preferred finish is achieved. The final step in the polishing process involves sealing, to protect the surface from chemicals, oil, moisture and staining.
