Decorative finishes for concrete floors of prefabricated metal buildings provide durable, economical and stylish flooring options. Any one of techniques involved including chemical staining, scoring, coloring, stamping, etc. can be applied to new or existing concrete floors of prefabricated metal buildings, allowing for limitless designs and colors.
The last post talked about chemical staining. This post dwells on the other different methods of achieving color, scoring and stamping concrete.
Scoring concrete floors of prefabricated metal buildings involves making shallow cuts, which is no more than 1/8” deep, to convey tile gout lines or to create geometric designs and patterns. This can be done in conjunction with the other coloring methods.
Stamping concrete floors of prefabricated metal buildings is the option of those who want their floors to look like materials other than concrete. The technique involves imprinting the outline and textures of stone, brick, tile, wood planks, leather, slate, etc. into the freshly cast concrete surface to achieve the look of these natural paving materials.
Concrete floors of prefabricated metal buildings can be colored in different ways. Integral colorants can be added during the mixing process to produce uniform tinting throughout the whole slab. In addition, the method ensures that consistent color is produced for every batch. When coloring is done prior to stamping, a more variegated natural look is achieved by using integral colorants as a base tone then modified by color hardeners and release agents.
Sprinkling color hardeners for freshly placed concrete floors of prefabricated metal buildings achieves more intense hues than those produced by integrally colored concrete. Using color hardeners prior to stamping improves surface durability. On the other hand, when combined with chemical staining, brighter or deeper finished colors for concrete floors of prefabricated metal buildings, is achieved.
Another coloring method is through the use of pigmented powder or liquid agents, which is usually combined with pattern stamps. This way the friction is reduced and allows for easier removal from fresh concrete surfaces. Owners of prefabricated metal buildings opt for this technique, together with color hardeners to produce a more “antique” look for their concrete floors.
To color existing concrete floors of prefabricated metal buildings, applying surface overlay materials is one option. Thin layers of cementitious material is applied to the concrete surface to flatten it or to prepare it for stamping.
Of course, concrete floors of prefabricated metal buildings must be sealed and waterproofed and colored materials for such processes are available. Choices range from buffing waxes to clear coatings to industrial sealers, depending on the use of the metal structure.
