What is profiled concrete substrate?

Mechanical scarifying, also known as profiling, is the perfect profiling technique for removing vegetable oils, sealers, petroleum-based products, and coatings from the surface of the concrete. Concrete prep procedures can help minimize any dirt or debris that may inhibit bonding of the concrete with the bonding agent.

What does CSP mean in flooring?

A Concrete Surface profile (or a CSP for short) is simply a standard measure used to determine the profile (some say roughness) of the surface of your concrete floor.

How is concrete roughness measured?

The surface profile of prepared concrete surfaces can be assessed qualitatively using ICRI Concrete Surface Profile (CSP) chips (with or without a replica disc created using a proprietary epoxy putty), and can be assessed quantitatively by using a specially designed micrometer that measures the peaks valleys of the …

How do you roughen concrete surfaces?

Water jetting – It is used to roughen concrete using jets of high pressure and ultra high pressure water, typically 5,000 – 40,000 psi. An experienced water jet technician can produce a surface profile as low as a CSP 3 and high as a CSP 10. Water jetting is a dust free alternate to sandblasting.

What does a concrete scarifier do?

Scarifiers, also known as surface planers or milling machines, cut or scar the surface of concrete with the use of cutting tools that rotate around a drum. Scarifiers remove concrete faster and more aggressively than grinders due to the pummeling action of the cutting wheels that rotate at very high speeds.

What does CSP stand for in concrete?

But what is a concrete surface profile? A concrete surface profile, known as a CSP, is a standardized measure for the ‘roughness’ of a surface that is defined by the International Concrete Repair Institute (ICRI). A very rough surface will have a high CSP number, such as CSP 9.

What is concrete Laitance?

Laitance is the weak, milky or powdery layer of cement dust, lime and sand fines that appear on the surface of concrete. These fines rise to the surface of concrete that was over-watered, or allowed to dry prematurely in the absence of curing membranes or other good curing practices.

What is standard roughness?

Surface roughness, often shortened to roughness, is a component of surface texture. It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. Roughness plays an important role in determining how a real object will interact with its environment.

Can you rough up concrete?

Concrete driveways have their own set of texture problems. Driveways that are too smooth are also difficult to drive on. When finishing your concrete driveway, a grinder can be used to roughen the surface to make it safer.

How much concrete can a scarifier remove?

Scarifiers are also versatile — many models offer adjustable cutting depths, and some can remove up to 1/4″ of concrete in one pass. The typical production rate for a concrete scarifier is 350 to 1,500 square feet per hour.

What do you need to know about concrete surface profile?

For proper bonding of overlays and coatings, it is important that a concrete surface have the correct Concrete Surface Profile or CSP. A CSP rating is a standardized rating that allows you to visually determine the concrete surface roughness.

What is the roughness of a concrete surface?

A concrete surface profile, known as a CSP, is a standardized measure for the ‘roughness’ of a surface that is defined by the International Concrete Repair Institute (ICRI). A very rough surface will have a high CSP number, such as CSP 9.

What does the CSP stand for in concrete?

Which is the best definition of a concrete slab?

A concrete slab is the foundation of a house or building in construction, made using concrete. This is a foundation that is flat, uniform, at ground level, and is not segmented. Without a solid concrete slab, the entire home could become unstable and its use could be problematic.

What do you mean by concrete surface profile?

In the case of concrete, the concrete surface profile (CSP) is used to describe the concrete’s outer surface texture. Concrete may need to be prepared for repairs and overlays, or to clean and/or roughen the surface for the application of a subsequent protective coating.

What kind of profiling is used for concrete?

Large or difficult surfaces will usually be mechanically profiled. Mechanical profiling is the method of choice.

What is the ICRI guideline for concrete surface profiles?

The International Concrete Repair Institute (ICRI) designates the CSPs in the ICRI Guideline No. 310.2R-1997, Selecting and Specifying Concrete Surface Preparation for Sealers, Coatings, Polymer Overlays and Concrete Repair. ICRI produces a set of CSP coupons that replicate each of the 9 profiles, which we use to train and measure.
