Frequently Asked Questions

What is Mould?

What is mould? Or often more specifically, what is black mould? These are questions that are frequently asked of us. Well, mould is a fungal organism belonging to the same family as mushrooms, yeasts and other fungi. Mould spores are present all around us but it is only under persistently damp conditions that they really thrive and become visibly apparent. It is mould which "grows a beard" on that tomato lost at the back of the fridge, or on autumn leaves in our gardens. Moulds can aggravate allergies and cause respiratory and other related health problems including asthma. However, not all moulds are bad, "penicillin" is a mould derived medicine responsible for saving thousands of lives.

Why have I got mould in my home?

Black mould covering walls and ceiling

Mould does not discriminate according to the size, age or even necessarily the general condition of a property. It will just grow where the conditions are right and the right conditions are where there is both moisture and a nutrient source. (e.g. wood, plaster or even paint.)

Some typical moisture sources include:

  • Condensation
  • Leaking plumbing
  • Penetrating dampness
  • Rising Damp
  • Roof leaks
  • Showering/ Cooking / Drying wet clothes

Until a few decades ago black spot mould growth was commonplace in buildings, often caused by rising damp or structural defects. But as building techniques improved and remedial damp proofing methods became more sophisticated the problem became less prevalent. However, in recent years the drive for energy efficiency has given black spot mould the chance to make a comeback. In trying to retain heat within a building we often retain moisture as well (from kitchens, bathrooms and every day living) and it is excess trapped moisture which provides a breeding ground for black spot mould growth. The advent of neat fitting, energy efficient, double glazed windows and doors together with improved insulation removes the "natural" draughts which provided unseen ventilation in years gone by. This coupled with our love for central heating creates a warm, cosy, damp environment for mould to thrive in.

What is Anti Mould Paint and how does it work?

Anti-Mould paint covers mould staining and prevents future growth

If your wall is suffering from unsightly black spot mould growth, our Anti-Mould Paint is the answer. Containing an active film fungicide, Anti-Mould Paint (in conjunction with improved ventilation) will prevent the future growth of black mould, mildew or algae usually associated with condensation and high humidity. Anti-Mould Fungicidal Paint is compatible with conventional emulsion.

Kingfisher ANTI-MOULD PAINT is a high quality acrylic based emulsion paint which when applied, provides a rich satin finish. The paint is specially formulated and contains an active film fungicide which will prevent any future growth of moulds or algae.

The fungicide is highly active against black spot mould growth (Asperillus Niger) usually associated with condensation and high humidity environments. The coating is effective for both internal and external surface applications and the fungicide will not leach out, even when wiped.

Kingfisher ANTI-MOULD PAINT can be used in any situation where mould or algae growth has been a problem. The surface is fully washable so dirt and grime can be easily and simply wiped away.


Scrape off any loose paint and brush down to remove dust and flake. Apply a solution of Kingfisher Bio-cleaner with a sponge or brush and allow to dry. This will kill off any presence of mould.

Kingfisher ANTI-MOULD PAINT is simply applied with brush or roller.

What is Anti Mould Paint Additive and how does it work?

Just add 120 g of Anti-Mould Paint Additive to 10 litres of any ordinary emulsion or water based masonry paint to make your own fungicidal paint. Anti-Mould Paint Additive creates an effective fungicidal paint which gives similar mould inhibiting properties to our ready to use Anti-mould paint described above. Eliminates the re-growth of unsightly black mould.

We recommend that you pre-treat any existing mould with Kingfisher Mould Cure to sanitise the surface for painting.

Our additive is a neutral colour so it can be added to paint of any colour without altering the final finish of the paint.

What is Thermapaint Insulating Emulsion and how does it work?

Thermapaint insulating emulsion paint is the ideal solution for warming up cold rooms and improving the thermal efficiency of your home.

  • Easy to use; DIY or Professional
  • Reduce thermal transfer by up to 20%
  • Big savings on your heating bills
  • Lower your carbon footprint
  • Reduces or eliminates condensation
  • Domestic or Industrial use

How Thermapaint works

Thermapaint catches heat in vacuum microspheres and reflects it back into the room, reducing heat loss.

Conventional insulation works by SLOWING the rate of thermal transfer through walls and ceilings but Thermapaint's microspheres PREVENT heat from transmitting to the cold wall in the first place. Thermapaint is manufactured using millions of tiny hollow ceramic spheres, each of which is an individual vacuum. The significance of this is simply that heat cannot pass through a vacuum (think of a Thermos flask). The microspheres in Thermapaint are therefore non-conductive so the heat has nowhere to go except back into the room!

Note: Turning your thermostat down by 1 degree saves around 50 / year on your heating bills. For more information, contact the "Energy Saving Trust" (EST).

What is Thermapaint Anti Mould and how does it work?

  • Kill Mould & Reduce Energy Costs - In one!
  • Reduce or Eliminate Condensation
  • Ideal for Bathrooms & Showers
Thermapaint Anti Mould coats surfaces with an active fungicidal film, inhibiting mould re-growth.

Thermapaint anti-mould paint is a unique product combining Thermapaint's ceramic microsphere technology with our latest anti-mould paint chemistry. This DUAL action paint robs Black spot mould of the moisture it needs to grow by warming the wall surface to lower condensation by up to 96% and then forms an active-film fungicide to deter further black spot mould growth.

Thermapaint anti-mould paint has the same energy saving properties as our Thermapaint insulating emulsion.

Note: Before applying, you must treat existing black spots with Kingfisher Mould Cure to ensure maximum effectiveness.

What is Thermapaint Liquid Membrane and how does it work?

  • Damp Storage Cellars
  • Garages/ Outbuildings suffering from damp and condensation
  • Exposed brick or stone internal walls
'Damp Proof Membrane' Holds back damp & Microspheres, creating warmer surface and reducing condensation.

Thermapaint liquid membrane is a revolutionary hybrid damp proof paint, combining advanced latex polymer technology with"Thermapaint's insulating properties to create an outstanding insulating and structural waterproofing product.

Thermapaint Liquid Membrane applied to masonry forms a highly effective barrier against penetrating damp even where the external wall may be partially or even totally below ground. In addition Thermapaint Liquid Membrane raises the internal surface temperature, reducing or eliminating the incidence of condensation.

Note: Before applying to brickwork etc, it is essential to apply Kingfisher anti-sulphate solution to neutralise groundwater salts.

What is DampGuard Liquid Membrane and how does it work?

Damp Guard Liquid Membrane.

This amazing product is a little known trade secret which can be applied to concrete, brick, renders & more. To protect against dampness/ water ingress by formimg a Damp Proof Membrane. Damp Guard is also ideal as a vapour barrier under plaster or render, for balcony repairs or as a concrete surface coating.

Neutral formulation means it can be used as Damp Proofing Membrane for fish ponds and portable water storage. Damp Guard can be used in storage cellars where it is highly effective at keeping out seeping water. Providing a bright fresh decorative finish which can be over painted if required.
