We recommend you to get a qualified tradesman to
apply your
spray-on flowcoat concrete surface. It is important that it 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 creating spray-on flowcoat 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. Flowcoat
patterning requires high quality materials, so we recommend you only use
genuine Hunter Press Crete products for your job to ensure the best
possible results.
If you are having
trouble with an existing spray-on flowcoat surface, see our
FAQ page or contact us.

How
do you apply
spray-on
Flowcoat?
The Formula
To make spray-on Hunter Press Crete
Flowcoat, simply mix 1 bag of Flowcoat colour to 4 litres of activator.
This mixture is applied with a hopper gun, which is
powered by an air compressor at a pressure of 30-40
psi
How do you apply Flowcoat?
Please Note: Flowcoat is a polymer based
concrete product. It is strongly advised that it is NOT applied where the
air temperature exceeds 33°C.
1.
The concrete surface must be thoroughly clean. Cleaning is usually done by
scrubbing the surface or high pressure water blasting and then washing it
with a solution of 8 parts water to 1 part hydrochloric acid (nb: this
solution may be further diluted to suit particular surfaces, such as
coloured concrete)
2. Wash again with water
3. After surface is dry, apply a solution
of 1 part activator to
5 parts water. This solution acts as a primer
4. Lay the stencil pattern on the concrete
surface. The stencil is held in place using blu-tack. Wood can also be
used to further secure the stencil to the surface
5. Mix the flowcoat (ie. 1 bag of flowcoat
to 4 litres activator)
6. If required, activator may be diluted prior to adding to mixture
to a MAXIMUM ratio of 3:1 (3 parts activator to 1 part water)
7. During seasonal perieods where temperatures generally exceed 25
degrees (c) it is recommended that you add 75ml (1 bottle) of retarder
per 4 litres of activator. This will slow the hardening process and give
you more time to spray the mix onto the concrete surface.
8. Pour the flowcoat into the hopper gun (nb.
only half fill hopper gun or mixture may be too heavy to use and
also may harden prematurely)
9. Spray flowcoat directly onto the
concrete surface (nb. one bag of flowcoat should cover approximately 18-20
square metres. Spraying the product achieved a textured finish
10. If you wish to achieve a smooth
surface, you can do so by TROWELLING the Flowcoat into the surface (if you
wish to do this, disregard steps 6 & 7)
11. When dry, remove stencil
12. Clean flowcoat residue using an air broom or
normal broom
13. Apply Hunter Press Crete high gloss sealer
after two days
