method produces a result very similar to that
achieved with the use of stamping mats on freshly
A thin coat of high strength polymerized concrete
is laid over an existing concrete surface that
is in good condition and is then textured with
mats. The mats used are of a lighter and smaller
construction than those used for stamping.
The steps in this process are similar to those
used for stenciling over existing concrete. However
instead of the 1-3mm thickness of concrete laid
over the existing concrete for stenciling, it
is applied by trowel to a depth of 5-20mm. This
allows a sufficient thickness of concrete for
textures of a reasonable depth to be applied.
The same thorough cleaning by pressure hose and
acid etching are required before starting work.
Once cleaned a primer coat is applied to provide
a strong bond between the existing concrete and
the new overlay.
The overlay concrete mixture which may be coloured
is mixed with just sufficient water to provide
a workable smooth consistency and trowelled or
floated onto the primed surface to the required
level for applying texture with the chosen texture
The concrete overlay can be left smooth, textured
with a broom, texture roller or texture mat.
