Surface Profiling Benefits

Wednesday, February 18th, 2015

What is the benefit of surface profiling prior to installing any new coating, marking or overlay material?

Smooth, non-porous surfaces prevent new coatings, overlay or repair materials to mechanically bond to the underlying substrate surface. Surface profiling opens the substrate pore structure to allow more of the new materials to be absorbed into the surface, promoting a lasting physical bond.surface profiling

Surface profiling is an intensive process, and will NOT be accomplished without clearly written specifications that detail the acceptable “surface profiling” to a specific SP range. Just writing “surface preparation” will only result in a simple surface cleaning of dirt and debris by broom, pressure washer, or blower.

Surface profiling is defined as the creation of a specific surface profile pattern, confirmed by profile number (1-10), using select abrasive equipment outfitted with the proper cutter tools, dependent upon the surface type and the coating, overlay or repair material to be applied. Confirmation that the desired profile has been achieved is done by visually comparing the surface to the profiles depicted by a profile chart, replica profile tiles, replica putty, replica tape, or SP photos.

surface profiling

The profile chart is a visual representation of the desired surface textures, roughness, and general appearance created on concrete and asphalt surfaces. The texture and appearance of the profile will vary, depending upon the concrete/asphalt strength, composition, aggregate and finish. It can be confirmed by profile number, ranging from SP1 (nearly flat) smooth surface, to SP10 (extremely rough) with amplitude greater than 1/4”. On sound surfaces, the range of variation can be controlled to represent these standards, however, as removal depth increases, the profile of the prepared substrate will be increasingly dominant by the type and size of the coarse aggregate.

This video demonstrates the proper selection of the right cutter assembly, array and rotation to achieve the desired SP1 to SP10 surface profile; best for erasing, grooving or prepping concrete or asphalt surfaces. Proper surface preparation modifies the surface by opening up of the pore structure to establish the right profile, suitable for getting any new pavement markings, repair materials or overlays to physically bond with the surface.
Now unless surface preparation is properly defined in the work you do, it will not be performed, and all that should be expected on the job will be surface cleaning with a broom, blower, brush or water.
Using the right orbital or drum-rotating equipment will produce different surface patterns. An orbital rotation offers less surface depth penetration, ideal for removing markings without surface marks or grooving patterns. A drum style provides sharp-edge grooving and deeper surface penetration, ideal for prepping or grooving applications.

 

Depending upon the conditions of the surface and/or the selection of the new overlay material, one or more surface profiling steps may be required, since one style of machine with one cutter style cannot accomplish every job, material type and surface profile pattern. Selection of the right removal equipment should NOT be required by contract, but by the installer’s ability to correctly prepare the surface and/or remove the existing coating overlay, while leaving the required SP1 – SP10 surface profile range necessary for the new material.

When removing and relocating markings to a new location, the profiling process must permanently remove the prior marking material. That means no pavement scars or traces of removed markings that may conflict with the new markings, regardless of weather and light conditions, for its entire service life.

The equipment selection and use must take into consideration any impact loads that may weaken or fracture the substrate, called “micro-cracking,” which makes surfaces unstable and unsound. Unsound surfaces shall be immediately repaired prior to the the next step. After the sound, profiled surface is confirmed, the surface should be dry and cleaned prior to installing the new coating or overlay material.

SMITH SR25 Sulky Driver

Thursday, February 5th, 2015

Why you need to dump your line driver and lazy driver to get the SMITH SR25 Sulky Driver now!

For those of you who thought they found an easier way to get their employees to push a paint striper across a parking lot or roadway learned otherwise at the 2015 National Pavement Expo in Nashville. At the NPE exhibit hall, stripers were lined up to see just how easy the new SMITH SR25 is to control the speed of painting stripes or removing lines.

The drivers they currently own use a dual pedal system, where the operator has to point their toe or flex their heel unnaturally to control forward or reverse speeds. Therefore, the consistency of any sprayed marking material or removed stripe will not be maintained over short or long distances.

Because the operator has to apply an unnatural foot stretch for long periods of time – often with cramping muscles – it is impossible to assure the stripe applied at the beginning of the job at the right thickness, or removed at the right depth, can be maintained throughout. Ballerinas have to train for years to be able to get on point for a 2-hour performance, but how do you prepare your muscles to stay on a line pointer throughout an 8- hour day at exactly 2.2mph with a perfect 62 degree pitch? That’s really stretching your foot, ankle and calf muscles to the breaking point.

Not easy!

The SMITH SR25 simple-pedal system performs naturally with simple heel pressure at rest, much like driving a car. So, striping or removal speed is set without any effort, and can remain effortless all day long. This translates into happy employees who actually enjoy the work, and happy customers who get the stripe you promised, and happy estimators with numbers that can be delivered time and again. The pedals alone make it a winner, but there is so much more that make up the SMITH SR25 that you really can’t afford not to own it now.

An operator can work all day long without profusely sweating with a sunshade protection, and go all night with dual LED directional lights to help you see exactly what you’re doing and where you are going without blind spots.

If you need to reach a worker on the job, their phones will always be charged in the handy cellphone charger. What’s more, any other electrical component, such as a counter or laser pointer, can be plugged into the front control center, neatly protected under the seat inside the convenient protected storage box.

SMITH thought of every operator convenience, including an LED rear flashing light, a safety kill seat switch, and electric key start within easy reach. The seat is supportive and supple, and can be adjusted back and forth for any size operator. Attaching any walk-behind striper or grinder with handles to the adjustable ball hitch is a snap.  And if the driver gets thirsty, dual cup holders on both sides of the seat hold the largest soft-drink cups – even Big Gulps – right where they need to be.

A rear tow bar can pull any supplies within payload capacities, and is positioned to prevent tip-backs.    Working on the machine is also a snap, with all components built in-line with an outer chassis that can lift off to work on the hydraulic drive components. A 7HP engine sits sideways conveniently behind the seat for easy access for any required maintenance or re-fueling, and is protected by the tow bar frame for transport. Because the engine cleverly sits sideways, it saves 6” on your pickups or trailers for carrying even more job supplies.

But that is not the only reason to dump your existing driver for the SMITH SR25. The clever designers at SMITH made the SR25 in heavy-duty stainless steel, so it will look just as sharp in 10 years as it does the day you receive it (notwithstanding a few errant paint sprays from jobs) with no rust.

How much does it cost to own the latest and greatest SMITH SR25? A lot less than you think. However, not owning one now may cost you more than you realize after your competitor gets their hands on one before you do!

For more details on the SMITH SR25, please contact your authorized SMITH Representative today.
