4 WAYS to ELIMINATE MOLD ON WALLS in a scientific way
In the previous video we introduced the problem of domestic humidity, previously responsible for the formation of mold in the home.
We have seen how as the temperature increases, the amount of water vapor present in the environment also increases and how, by reducing the temperature, this water vapor condenses.
And where condensation forms mold...
So let's go and scientifically analyze which are the 4 most effective ways to eliminate mold from walls.
But let's go in order.
There are 2 types of moulds: the mold caused by the infiltration of water inside the wall, or rising water, and the mold that arises due to the internal condensation that we mentioned above.
In the case of rising damp or infiltration, we are faced with a white mold that hides together with the layers of paint and plaster that detach from the wall.
To eliminate this scourge it is first of all necessary to limit the cause of the infiltration and, in the event of rising damp, it is necessary to use a transpiring plaster capable of "venting" the humidity from the wall without however suffering aesthetic damage.
If, on the other hand, we have a house infested with black mold, it means that we have internal humidity problems.
This dark mold usually forms behind the furniture, in the corners of the rooms, in the kitchen, and is caused by the surface condensation of the humidity present in the house.
As described in the first video, humidity tends to condense only if it finds areas with a temperature lower than its "dew point temperature".
We therefore have two ways to solve the problem of internal mold:
1. INCREASE THE SURFACE TEMPERATURE.
If our walls have a higher temperature than the dew point, domestic humidity does not condense and, consequently, does not generate that dark mold behind the furniture.
To raise the temperature of the walls we have two different possibilities: I can HEAT the environment more, an expensive practice, or I can improve the domestic INSULATION, so as to keep the internal surfaces "warm".
2. REDUCE INDOOR HUMIDITY.
By lowering the humidity, i.e. the amount of water vapour, the dew point temperature also decreases.
In doing so, the low humidity will not condense on the cold spots in your home.
It seems like a repetition, but even in this case we have 2 ways to reduce internal humidity: DEHUMIDIFY, using mechanical systems, such as the classic dehumidifier (chemical salts can only be used in wardrobes), or I carry out an AIR EXCHANGE.
Thanks to the mixing of colder and therefore drier external air with internal air, I decrease the ambient humidity.
However, ventilation must be done in an intelligent way, in order to avoid "throwing out the window" of the money spent on heating the house.
The most effective solution is certainly controlled mechanical ventilation (VMC) which manages to guarantee a constant exchange of air without cooling the house.
