The microcrack has been completely re - crystallized by KF-G.
is a liquid spray on a concrete for rehabilitation of degraded rheology
KF-G represents a new concept in concrete rehabilitation technology and became highly recognized by its
effective performance and simplicity of application. In most cases, after KF-G is applied to the damaged area
there is no need for it to be covered with any additional layer. Concrete surface looks the same, but strength,
corrosion resistance and impermeability to the liquids responds to features of High Performance Concrete.
APPLICATION OF KF-G FOR CRACKS < 2 mm wide
It is a common knowledge that cracks less than 2 mm in width are not repairable at all. The total volume occupied by micro-cracks is much larger than the total volume of repairable cracks. KF-G actually heals these micro-cracks and
increases compressive strength by 30% to 50% after 28 days.
APPLICATION OF KF-G FOR CRACKS > 2 mm wide
If it is required that the concrete be uniformly cured, must be relined in accordance with Application FOR CRACKS
APPLICATION OF KF-G AS A REBAR CORROSION INHIBITOR
As a Corrosion Inhibitor meeting the requirements of ASTM C1582, which is sprayed onto the concrete. It chemically inhibits the corrosive action of chlorides on reinforcing steel and prestressed strands in concrete.
The self-healing process is visual just after KF-G spray.
The crack is completely healed. Seen is superficial slight white trace. After 4 days that white trace disappeared.
Deformational crack with width at 3 mm.

INJECTIONS OR SPRAY?
IT IS NOT A QUESTION,
Re-calcination of concrete by KF-G results in“sewing” of any voids including of microcracks with density increasing, measurable in at 4 to 72 hours depending on initial density loss.
Pour or spray KALMATRON® KF-G as a water solution
and distribute it evenly by the brash as shown at right.
Treated concrete become waterproofed and strengthened
by resistance to compression, abrasion and rupture.
For the most of projects it is enough to accept project as
accomplished especially when resurfacing is not needed.
