Breathecoat Smooth with AF, WR & Stretch 3.4kg
Breathecoat Smooth with Anti-Fungal is
a functional coating system with the specific purpose to allow water vapour to
evaporate from the substrate, but not allowing any water penetrating the
substrate from the exterior. It presents the capability of killing the presence
of fungi and disallowing any further fungal growth. It is available in a range of colours.
• To allow damp saturated walls to breathe vapour
out, without the paint peeling, through the application of membrane
• To kill and counter fungal growth in humid and
damp areas where ventilation is limited.
• Breathecoat Smooth with Anti-Fungal
is also environmentally friendly, containing no VOC’s and do not leave an
unpleasant smell, once applied.
• Wall substrate only needs to be touch-dry.
• Wall substrate must be sound, oil and fat free.
In the case of brittle or less firm substrates,
dilute the first coat of Breathecoat Smooth with Anti-Fungal,
using an extra 0.5L of water, on top of the required 3L of water. This
specifically applies to straw bale houses ensuring depth penetration, to
stabilize the substrate.
• Walls infested with fungal growth to be washed
with a white vinegar solution of 10% white vinegar in water and thoroughly
rinsed with water afterwards. In areas where fungal growth is harsh, scrubbing
with a stiff hair brush and the white vinegar solution might be required.
• On hot and windy days, pre-damp the substrate
before application on exterior surfaces. No excessive water on the substrate.
• When applied to already painted surfaces, all
loose and flaking material must be removed. If the painted substrate presents a
smooth or glossy sheen, the surface must be sanded using a 200 grit sandpaper
to ensure a profile for good bonding. One the substrate has been sanded; all
dust must be removed before commencing with painting.
• In areas where damp issues occur, such as
rising damp or other, causing the existing paint to peel, flake or blister, at
least 80% of the existing paint needs to be removed up to a distance of 800mm
from the infected area. All gypsum based skimming compounds such as Cretestone
or Rhinolite, must be completely removed to the bare plaster.
• No primer is required.
Decant 3L of water in a suitable container.
Gradually add the 3.4kg of powder, while mechanically stirring. Mechanically
mix for 3 minutes after the last powder is added and allow standing for 30
minutes. The mixture will yield a volume of 5L
• Apply, using a “Hamiltons Classic” roller and
brush. First saturated the roller in the paint on a paint tray and complete a
“V” shape on the wall. This is to ensure that the paint is evenly distributed
on the roller. Cut in corners, using a brush, and apply the paint from corner
to corner or joint to joint, without a stoppage. Keep a wet edge and do not
touch up after the paint has dried. The latter applies for dark colours.
• If the mixed paint in the bucket is thickening
up, while painting, do NOT add extra water. Just stir again to repair the

• Coverage: 20m² to 35m² per 5L per coat,
depending on the substrate profile.
• When the substrate change in structure, a mesh
strip, soaked in the Breathecoat Smooth with Anti-Fungal
paint, must be placed over the interphase, overlapping 50mm on each side. Once
the strip is touch dry, apply the Breathecoat Smooth with Anti-Fungal
as per specification above.
Do not apply as an external application, should
it rain within 72 hours.
The coating can be post-cured the next day, using
a fine mist spray from the bottom to the top.
• Pot Life:
• Coverage: 20m² to 35 m² per 5L mix
per coat, depending on the
• Dry Film Thickness: 80μm – 100μm per coat.
• Tensile Adhesion: 0.89N/mm² on cured concrete.

Breathecoat Smooth with Anti-Fungal is
cementitiousand if applied on
exterior surfaces, specifically the darker colours, rain might cause
efflorescence (a white powdery residue, due to the water washing the
non-soluble salts from the paint layer, noticeable on the darker colours ).
Efflorescence might take 6 months to 9 months to wash out completely before it
will start fading away. Four weeks after application, if efflorescence occurs,
a 10% solution of white vinegar can be used to wash it or clean it.
To avoid efflorescence:
- Apply a thin mist spray onto
the newly painted surface, spraying from bottom
to top, a day after paint application. Repeat one day later. This will cure
the paint quicker.
- Apply Breathecoat Acrylic
take 28 days to reach full cure. After 28 days it will reach maximum strengths
and wash ability.

variation. Substrates must be thoroughly prepared.
