The Concrete Profiler (TCP) and TCP Deluxe
In the building and other associated arts it is common to coat or overlay surfaces of various structures for protection and/or aesthetic purposes. Concrete is the most coated building material in the world and questionably the most prone to coating failures. There is now new specific test procedures or methods developed that provide a permanent replica test for determining concrete profiles. Unlike steel, concrete is very porous, which may have been the rationale for not developing a permanent replica test method for determining concrete profile. A new ASTM standard D7682 utilizes the TCP in both Method A (visual) and Method B (quantifiably measuring) surface profile..
One of the most important characteristics for a coating or overlayment bonding is the texture or "profile" of the concrete. The upper portion of a slab surface is often called the anchor profile or surface profile and is a measure of the surface roughness. However, in the past, the concrete surface preparation industry has not generally "measured" the profile or roughness. On steel surfaces, for example, a permanent replica tape is used to quantify the profile. Amid today's cost for surface preparation and high performance coatings and the preponderance for coating failure, permanent replication along with precise quantitative analysis ensures achieved surface roughness and can be used as proof for later edict. The TCP is the only product able to provide a permanent record of anchor profile of concrete/steel surfaces. The TCP was developed by O.T.B Technologies Inc. Scottsdale AZ.

The Concrete Profiler Deluxe (TCP Deluxe)
With the TCP Deluxe kit the hardened TCP replica can be both visually compared to the supplied ICRI CSP coupons, or placed onto the specially built micrometer bottom anvil and tested at various spots and recorded (suggest at least 10 spots - highest to lowest). The lowest reading is subtracted from the highest reading to determine the profile range for that sampled concrete spot.
The profile range can then be numerically compared to the ICRI CSP coupon range. The use of the Deluxe TCP kit allows the owner, contractor or inspector to quantitatively determine the concrete surface profile that removes "guess work" while at the same time obtaining a permanent replicaof the prepared concrete surface profile.( ASTM D7682 Method B)
ICRI CSP Profile Range
ICRI #1 = 27mils +/- 5 mils (686 microns +/- 127)
ICRI #2 = 32mils +/- 5 mils (813 microns +/- 127)
ICRI #3 = 38mils +/- 5 mils (965 microns +/- 127)
ICRI #4 = 50mils +/- 5 mils (1270 microns +/- 127)
ICRI #5 = 66mils +/- 5 mils (1676 microns +/- 127)
ICRI #6 = 124mils +/- 5 mils (3150 microns +/- 127)
ICRI #7 = 175mils +/- 10 mils (4445 microns +/- 254)
ICRI #8 = 210mils +/- 10 mils (5334 microns +/- 254)
ICRI #9 = 214mils +/- 10 mils (5436 microns +/- 254)
Notice: for these profile ranges to be filled (DFT), it will require the contractor to purchase ~1/2 the profile range in 100% solids by volume material. Ex. CSP #4- 50 mils = 25 mils. Material amounts should be based on solids by volume percentages.
