Damp Walls, Wet Walls, Mould, Mildew: Problem Solved!
Whichever variation or combination of the above you may have… damp or wet walls, with or without ugly mould or mildew spots, it is an unpleasant environment to live in. It is now a well established fact that mould in your home is a health risk, especially if you have any respitory problems.
I hope to assist you here by approaching your problem by a broader understanding of the causes of condensation and mould to enable you make an informed choice as to the proper solution.
The 2 Main Reasons Why Walls Become Wet and Mouldy?
To clarify, we are dealing here with walls inside the home.
1. Condensation – by far the most common, or…
1 Condensation on walls… frequently described as damp walls, is caused when air moisture comes into contact with a cold surface – like breathing on to a cold mirror...turns 'foggy'' which, if continued, turns into water droplets. This moisture comes from various sources, wet or damp clothes left on a radiator to dry, a boiling kettle, and of course one of the main sources... the exhaled breath of the room's occupants.
Some people ask, where does this moisture go if it does not form as wetness on the wall? The best way to explain this is go back to our simple analogy above re mirror... if you breathe on to your own hand... being relatively warm, the air does not turn into moistue on your hand... it stays in the vicinity in the air.
Inadequate or no ventilation in the room will add significantly to that problem. Air moisture collects on the coldest surface within the room (usually windows & inside of external walls) where it then appears as wet or damp.
Apart from window glass, uninsulated or poorly insulated walls are usually the first places condensation will occur.
2 Water coming in from the outside… also called water ingress, is much less likely to be the cause of your inside walls being wet or damp. This can be caused by a crack in the outer wall, a badly fitting sill, damaged water down pipe, roof leak or even a porous wall affected by wind driven rain. We do not offer any product or service to fix this problem, but we suggest you first eliminate the most likely cause of the problem… condensation (above) as being the cause of your wet / damp walls.
One other problem worthy of mention under this heading is Rising Damp… i.e. moisture on the wall down at ground floor level (only) which usually shows on a wall behind and up a little over the skirting boards. This can occur on any wall, external or internal & occurs mostly in older homes where the use of a damp proofing membrane was not used during construction and therefore wetness from the soil soaks up & into the wall to a certain distance only. In the unlikely event that damp / wetness on your walls is coming in or up, the products we offer here will not fix the problem. However my suggestion is as follows…if it appears likely that the problem is Condensation as described above –our products(s) will be your most reliable & cheapest way of solving the problem.
Mould / mildew is a toxic living fungus that inevitably comes ‘to live’ on damp walls or wet walls because it is a suitable environment for it to grow on. Good for them - bad for you! Mould in bathrooms, mould on ceiling all comes from condensation on walls etc. Note re bathrooms... given the fact that a huge amount of moisture from the steam is present, during showers especially, you should ensure that an adequate extractor is fitted to remove the bulk of that steam / moise air. If you don't have a proper extractor, at the very least open the window.
We offer two solutions for mould prevention.
Option No 1.
Removing Mould / How to Remove Mould from Walls.
Next… to "mould proof" the wall, apply three coats of Thermilate Warmcoat Advanced Insulating Paint allowing enough drying times between coats. Although Thermilate is a water based low odour coating, please ensure proper ventilation and reasonable room temperature to dry the Thermilate Warmcoat between coats. You will find a roller better than a brush but you’ll need a brush for tight corners etc. If possible apply between radiator and wall also for obvious reasons. Thermilate Warmcoat is easy to apply; it goes on like any good quality interior emulsion.
Generally speaking and based on extensive feedback from customers, the Thermilate Warmcoat Advanced Insulating paint / process above will usually get rid of dampness and mould reappearing on your walls.
Note: In extreme conditions, or where you don’t mind paying a few more £ / € for some additional anti mould ‘insurance’ add some Mould Stop additive into the Warmcoat or into the final chosen paint / colour if using your Warmcoat as an undercoat only. This combination offers you the best possible solution to prevent mould.
My Recommendation: For best results, budget allowing, apply three coats of Warmcoat to all the walls and ceiling also because it will make that room a lot cosier, easier to heat and saves on heating bills due to less need for costly heating. If you are trying to keep costs to minimum, I suggest you apply three coats to inside of external walls and apply one or better still, two coats to all remaining walls and ceiling.
Coverage: 5 Litres of Thermilate Warmcoat Advanced Insulating Paint will cover all the walls and ceiling (two coats) in an average 12 x 9 sq ft box bedroom.

Option No 2.
The cheapest solution for mould on walls etc is Mould Stop. A powerful fungicidal anti mould additive developed for extreme Tropical conditions that can be mixed into any paint or even grout and it works by creating an environment on the wall etc which mould spores cannot tolerate and accordingly ‘decide not move in’!
Mould Stop is an excellent anti-mould product, but, unlike Option 1 above, it will not help to rectify damp / wet walls or heat retention in the room. If you are minding the pennies, Mould Stop, used in conjunction with any ordinary paint (indoor or outdoor) will keep mould away. Add some into the grout if you are having tiles fitted, keeps grout looking like new for years.
Mould Stop is suitable for indoor or outdoor use.Excellent in external masonry paint to keep walls mould free, especially in the vicinity of trees and shrubbery. Also wooden buildings, log cabins etc. Note: Mould Stop is not a mould remover. Make sure you kill all condensation mould properly first before re-painting. Mould Stop keeps mould away – it does notget rid of existing mould.
Coverage: One 50ml bottle of Mould Stop is enough to treat up to 10 litres of paint.
An increasingly popular solution for damp walls +/- mould is our Warmcoat Advanced Insulating Paint – a brush / roll on, easy to apply, super high tech paint which insulates & cuts the coldness on your walls, resulting in a big reduction or total elimination of wetness forming on the wall in the first place. This paint does not seal the pores in the wall. On the contrary, it allows the wall to breathe, a very important and necessary point, especially in older solid wall homes. Thermilate Warmcoat Advanced Insulating Paint is perfect for solid wall / old period homes where you are restricted as regards modification etc.
