Surface retarder
A concrete contractor defines surface retarder as a colorant used to create construction joints and to provide a smoother surface. Some of these agents are more effective than others and offer unique features, such as being color-coded and retaining etch at temperatures of up to 110 degrees Fahrenheit. Other surface retarders include Master Finish HC, HV, QD 200, and UC. A concrete contractor can use one of these products in a variety of applications to enhance the overall look and feel of concrete.
The market for concrete surface retarders is growing in many applications, including sidewalks, curbs, and bridge decks. Additionally, concrete surface retarders are used in the construction of concrete segment joints and facade cladding. Government regulations and increasing public and private investments in infrastructure development in Asia Pacific countries have bolstered the demand for concrete surface retarders. In addition to this, emerging economies such as China and India are making the most of these products to meet their growing environmental and energy efficiency goals.
Margin trowel
A margin trowel is a flat steel tool that has a handle. These tools are often used to smooth newly-placed concrete, and they have a wide range of different applications. Some types are used for specific tasks, such as filling a crevice in a concrete floor or applying a Stamped Concrete Columbia SC coating to a new wall. Still others are used to work with grout or fill small spaces. Concrete contractors have many different types of trowels, and knowing the difference between them is important.
A marbleized surface is created by putting different colors and finishes on the surface of the concrete. This finish is created by applying a thin layer of colored material on top of the concrete. A margin trowel is a tool with a short handle and a small blade. It is often used to scrape or apply patching materials to a concrete surface. Masking is another common application for a margin trowel. It involves covering a concrete surface with a mask, which is usually a clear plastic membrane.
Licensing requirements
There are various state-specific requirements for becoming a licensed concrete contractor. Typically, you must be over eighteen years old, have at least two to four years of concrete experience, pass a written exam, and have financial statements showing that you’re financially sound. Additionally, you may need to pass a criminal check and post a bond. Once licensed, you must renew your license each year. Below are some of the requirements for becoming a licensed concrete contractor.
First-time offenses for contracting without a license are typically a misdemeanor, and carries a fine between $200 and $15,000 as well as up to six months in jail. Subsequent violations carry a greater penalty: a second-time conviction can carry up to a 20 percent fine, $4,500 fine, and 90 days in jail. However, most states have minimum contract requirements for contractors, so make sure to check out these requirements before starting any work.
