We begin by listing 10 more frequent and erroneous beliefs and try to explain why they are counterproductive or harmful.
In the end even we discover the solution that will solve the problem seriously.
1) A little’ Mold has never killed anyone…
In fact there may seem harmless even some speck of mold scattered here and there on the walls, but actually a plague of leprosy is just the beginning of a proliferation that can get to become serious and alarming.
The spore the microorganism circulates the environment needed for its reproduction and for its expansion and is part of the more volatile particulates and existing light (PM 10) they are very easily inhaled through breathing and cause many allergies borne of our respiratory system. Some of the most common symptoms are: fatigue, my eZee, watery eyes, runny nose, cough, bronchial asthma, irritability, nausea, etc.
2) The mold will go away in the summer season, then just a painting.
And’ an absolutely incorrect and false statement, even though many finishers construction will be convinced (Perhaps self-interest). The truth is that mold is a fungus that thrives through spores that circulate freely in the air and settle anywhere. When they find a 'ground’ rapidamemente favorable they start to grow and to generate additional spores to procreate and colonize new areas. Being a fungus, prefers wetlands, hot and sheltered from direct sunlight, a wet wall is usually the best ally for these microorganisms because it provides enough water and food coming from the organic component of painting.
In warmer weather the fungus tends to remain stationary for unfavorable environmental conditions but does not die, It starts its life activity, however, from September to March when the environments are more moist and less bright.
Repaint every spring without deeply eradicate the fungus means to give back new life into the host providing it with organic material and moisture.
3) We remove the mold with vinegar, bleach or other gadgets
The traditional remedies such as vinegar, baking, alcohol, essential oils, etc. produce absolutely no benefit to the fight against mold, however, we certainly a very welcome addition to the food fungus that propagate stronger than before after a few days of treatment 'tonic'.
Not even the bleach or products containing chlorine or hydrogen peroxide can do nothing against this intruder; although at the beginning such treatment would seem resolutive, really just we whiten the stain, There intossichiamo the streets respiratoie and provide a more stable substrate moisture and water. The reason is that the former are chlorinated high salt content and, As such, We help the wall to retain additional surface moisture to the benefit for the fungus.
Some crazy use herbicides agricultural substances to fight against mold, needless to say they are absolutely toxic and remain dispersed in the walls for years. Maybe then we can say goodbye to the mold… but also to our loved ones!
4) Now that we have cleaned and bleached we can be assured
As we said, molds take root in our homes only in the most favorable points and constantly wet. Since it is impossible to avoid their spores because they are numerous, read and circulate freely in the air like dust and pollen, It serves restore the environmental condition and our walls. We must understand that the molds are not hostile to us, but we prefer because we offer a sufficiently hospitable home to them.
Fighting thermal issues related to condensation and air exchange are, for example, the first remedies against mold.
5) Increase the heat to dry a little’ i muri
Increase the ambient temperature in the cold season on areas that tend to rot is the safest way to make the situation worse. Knowing that the amount of air retained vapor is much greater as it is hot, it goes without saying that to understand a lot more water contains a unit volume and the more likely an event condensation.
In cases of high environmental temperature, since you do not mind spending, It is always convenient to also activate an air dehumidifier to avoid excesses of steam. We consider that the state igrostatico recommended for a good permanence in a closed environment would be by 30% al 55% humidity & agrave; relative. The higher the temperature, however, and most would be advised to keep the relative humidity towards the minimum (but we know that it is precisely when a humid environment is that it tends to have colder and thus increase the temperature of the heating).
6) In winter heating homes and avoid air exchange
Limiting the air changes the environment is among the most common mistakes that you tend to do when it is cold or when we spent a fortune on fixtures or for a top class home. Yet we must always remember that they are tenants to produce an excess of humidity, if the house is unoccupied and the heating off, the humidity is much reduced as the probability of having mold and condensation on thermal bridges.
In ordinary life it produces moisture with all our forms of human activity, from breathing emit about 2 liters of water per day per person in the form of steam, but then there sweating, then the hygiene, the kitchen, the laundry dries, the animals, green plants, washing floors, etc. A steam sea that can be summed moisture external media and concentrating in our environments, why you always need to vigorously aerate by opening all windows together for at least 10 minutes a day, preferably in the morning when it's cooler; just when the moisture content by volume is proportionally much smaller.
7) In summer, however, everything is different
In principle it may be fine to constantly open in the summer as long as you have not buried perticolarmente cold environments. The summer vapor content is in fact much higher and you are likely to carry a large amount of moisture inside our environments by generating condensation and mold poliferazione unexpected.
8) The window flap is a compromise…
For our environment, including the bathrooms, windows in vasistass can become a condemnation because this method of opening offers a very little exchange of air from the inside out, but in return, get very cold in winter and in summer a lot steam.
Better then, when possible and after every shower, to throw open 10 minutes and then reclose totally.
9) I have a new home is not possible to obtain the mold
It seems a contradiction but it is very common to have more in new homes of mold problems in buildings dating.
The reasons are in part already been explained previously. Excessive need to isolate and seal each spiffero substantially reduces the natural exchange of vapor with the fixtures.
The thermal insulation along the walls (usually non-breathable) reduce the microassorbimento and the exchange of vapor with the outside by means of capillarity.
These limitations needed to bring the building into thermal distribution rules, actually creates a watertight and waterproof system which leads to steam to saturate the environment inhabited by creating many clear condensation points and consequently dangerous mold outbreaks.
10) I did make a false-now disappear mold
Although highly recommended by experienced construction, create a false wall where you can not solve a mold problem (or humidity) equivalent to hide the dirt under the carpet.
The fact work, apparently decisive, It tends to degrade within a few years, burned money and a musty smell and cellar that invades us the house day and night, summer and winter.
The reasons are simple: creating a jacket between two walls it begins to intensify the steam in its interior and to establish immediately a few colonies of mold. As time goes by, the lack of light, the constantly high humidity, the colony begins to grow out of proportion and create filaments (or roots) always longer which they tend to bind with the settlements of the opposite side, also by transporting water on the side that would have to remain dry and isolated.
At the end of the unbearable smell of mold and humidity returned will persuade even the most tenacious to remove this membrane deciding to heal a time for all the wall now invaded from every form and species of fungus.
Knowing that you mentioned problems are extremely common, we aim to remember that it is the masonry the real environmental regulator. And’ the wall that, as well as an effective barrier and thermal regulation, also it provides an interface for the disposal of steam towards the outside. Similarly to a membrane, the wall is the best ally for the environmental health as long as it is kept dry and free to breathe.
Just for restoring health, breathability and efficiency to the walls that we recommend the use of igrodry; excellent against molds in the environment and to solve the walls subject to rising damp problems.
