We recommend you to get a qualified tradesman to lay your stencil concrete
surface. It is important that your decorative concrete is properly
constructed to ensure a long, hassle free lifespan. We have a number of
recommended quality tradesmen in the Newcastle and Hunter regions. Please
contact us for details.
The directions for stencil patterning below are to be used as a guide
only. There are different circumstances that may require different
techniques to produce the best possible decorative surface. We also
recommend you use genuine Hunter Press Crete products for your job to
ensure the best possible results.
If you are having
trouble with an existing stencil pattern surface, see our
FAQ page or contact us.

How
do you make Stencil Pattern Concrete?
1.
Form
up the area to be concreted at a depth of 100mm. We advise that you place
and additional 50 – 100mm of compacted sand under the proposed area to be
concreted
2.
Put your reinforcing steel in
place. Be sure to use bar chairs and that they have adequate lap for
reinforcing steel
3.
Pour concrete and screed it
smooth. Then use a bullfloat to complete the effect
4.
If you wish to have
cracker-joint construction joints, place them into the concrete now. If
you wish to have saw-cut construction joints, wait until after the job is
completed
5.
Unroll the stencil and place
it squarely onto the concrete (stencil can also be applied at a 45°
angle) and cut it to size. After placing the stencil onto the concrete
surface it must be rolled or trowelled into the surface. Do not apply the
stencil when the concrete is too wet or the stencil will sink into the
concrete too far and will result in broken edges when removed
6.
Now you have to apply the
colour. Put your concrete colour into a bucket and throw the colour onto
the concrete surface using a turning motion (like ‘feeding the chooks’).
Be sure to distribute colour evenly over the surface
7.
Trowel the colour into the
surface using a float of your choice. Then repeat step 5 and trowel the
colour in again to suit the finish you want
8.
When the concrete if firm
enough (but not completely dry – usually 3-4 hours after laying the
stencil), gently pull the stencil off the surface
9.
An air broom is generally
used to clean the concrete surface, but sweeping it the next day with a
normal broom will also be sufficient
Use saw cuts to allow expansion of the concrete. Jointex is not
recommended as the concrete sealer melts it and this will result in
staining of the surface
10.
Apply a concrete sealer about
four days after the job is completed. Ensure that the surface is
completely dry and if possible avoid humid or overcast conditions. If you
want to apply the sealer the same day, or if you wish to apply it in wet
or very humid conditions, use “wet sealer”. This will avoid the surface
turning ‘milky’
