Black Spot Mould
Specialists - mold treatments and condensation advice
to stop Black Mold Growth in the home.
1. Apply Surface
Cleanser to the wall with a sponge - allow to dry
2. Apply one or two coats
of Stain and Damp Primer,
to prevent show through of residual stain markings.
3. Add the AntiMould
Paint Additive to your chosen paint and apply as usual
4. Use a Condensation Monitor
called a Home Humidity
Meter to measure the moisture in the air in your house. Keep
the moisture reading between 55% and 65% to avoid Condensation. Ask
us for help in using this simple tool to keep your decorations and health
in good order.
Severe Black Mould - it only
growths in the pure water condensing from the air.
Less severe Black Mould -
patterns of mould indicate the surface temperature differences.
to stop Condensation in the home
1. Buy our Dehumidifier -
it has the running costs of a Fridge and as well as removing moisture
it provides some background warmth.
2. Fit our Trickle
Vents to your Double Glazed window frames.
3. Or for Houses, consider
a Loft Mounted Fan, known as
a Positive Pressure ventilation system
4. Or for Flats, consider
a Heat Recovery Fan, which
has a ceramic heat exchanger, to minimise energy loss.
4. Then use a Home
Condensation Monitor to measure the moisture in the air in your
house. Keep the moisture reading between 55% and 65% to avoid Condensation.

Test the walls of the building
with our Condensation Test Kit and look for evidence of mold - usually
'black spot' - this indicates that you have Condensation forming on
the coldest surfaces in the room. Unless you can increase ventilation
and heating, consider using our Anti-Mold Paint Additive or Anti-Mould
Emulsion Paint - guaranteed for 5 years!
If necessary, treat all plaster
with the anti-mold treatment supplied with the paint and then redecorate.
the amount of Moisture in the Air
Use our Hygrometer
to monitor the conditions in each affected room and use the Memory function
to check the exact conditions overnight, the time when temperature falls
and condensation is most likely. This meter helps you to control the
conditions that cause condensation and to monitor the use of your heating,
ventilation and dehumidification.
Available in standard and
large display versions

to test damp walls and timbers
forms on the coldest parts of your walls, floors and ceilings. If damp
is entering from the outside or from a water leak it will make the damp
areas colder and more prone to condensation, hence mould growth.
Firstly, check the outside
of the building for rainwater penetration - if the walls are absorbing
moisture apply a water repellent - Dampseal - check your downpipes and

of 'relative' dampness. Always use Meters to compare like materials,
never to give absolute moisture readings.

- Battery powered
- Direct visual reading
Can also be used to test
damp floors and new concrete floors.

Summary of mold
or mould facts
Mould growth is caused by
Condensation forming on the surface or inside the building material
Condensation is caused by
high levels of moisture in the air condensing on the coldest surfaces
in the room, often at night when the temperature falls
Surfaces will be colder if
they are damp - rising and penetrating dampness, blocked wall
cavities or lack of them, can all increase dampness
Dampness can be caused by
common defects, like blocked gutters overflowing, poor pointing,
cracked external render.
