CONDENSATE HUMIDITY AND LIFTINGMOISTURE: WHEN IS  THERMAL PAINT NEEDED?

Rising damp is present in old houses on the ground floor: it consists of the capillary rise of water on the walls through the foundations not isolated from the ground. Many people ask us for "easy" solutions, in particular they would like to cover the damaged masonry with panels, sheets or plasters in order to eliminate the problem. One of the solutions to the problem of rising damp is not to coat but to replace the old deteriorated plaster with a specific plaster: macroporous to easily disperse humidity and resistant to the passage of humidity.

Condensation humidity, on the other hand, is a much more widespread phenomenon because it concerns many homes, even recently built, the causes that favor the condensation of water on the walls and the consequent molds are essentially three:
Lack of thermal insulation of the perimeter walls: due to the lack of thermal insulation of the masonry, in the cold period, the water vapor inside the house comes into contact with the cold wall, condenses and constantly wets the wall creating the appropriate conditions at the onset of mold. By improving the thermal insulation of the masonry the phenomenon decreases or disappears completely permanently.
Indoor low temperature: at low temperatures the water vapor condenses more aggravating the phenomenon. Improved thermal insulation facilitates the increase in ambient temperature and allows humidity to remain in the state
of water vapor, without condensing on the walls.
Poor ventilation in the interior: it is no coincidence that the phenomenon of condensation and mold is favored by the poor air circulation in the rooms, behind the cabinets, in the closets or more widely in the corners. The lack of air exchange is now aggravated by the new windows that are much more "tight" than the old models of the past.

Lack of thermal insulation of the perimeter walls together with the poor ventilation of the rooms creates the worst conditions, more favorable to the onset of mold and the unpleasant odors that derive from it.
Once the houses were more lived, the families more numerous and very often the elderly "guarded" the house and could open the windows in the best moments of the day to favor the exchange of stale and damp air. This role is now entrusted to "controlled mechanical ventilation systems".
In any case, the most effective and permanent way to solve the problem of condensation mold is to improve the thermal insulation of cold walls with an anti-mold thermal paint that raises the internal surface temperature of the masonry and facilitates reaching a higher room temperature . The anti-condensation thermal paint is not a "chemical" solution against mold, which inevitably decays over time, but a permanent thermal insulation over time.
If the phenomenon is very serious, however, we recommend applying cork insulating sheets or panels to radically reduce thermal dispersion towards the outside with considerable energy and economic savings.

HOW TO PROCEED IN STRUCTURE OF CORK AND LIME THERMAL PAINTING?

products to use:

1-Anti-mold curative: if the wall is affected by mold, it passes TOGLIMUFFA all over the wall or only on the parts concerned if these constitute a minor part of the surface. The next day it removes mold with a rag and / or sandpaper.       
 
 
2-Bonding primer: apply with a short-haired roller over the entire surface. Bonding primer has a triple function: to consolidate the masonry, it creates a precise roughness of the wall and gives the right degree of absorbency to the wall.
 
 
3-Bioart-Painting / Plaster Thermal of cork and lime: the next day apply the thermal paint / plaster. Our advice is to apply the product with stainless steel SPATULA with rounded corners: in this way you get a nice smooth and regular surface.
WARNING: if you extend with a brush you will have to pass two hands and you will get a less regular rustic effect.

WHAT DOES THE THERMAL PAINTING PACKAGE CONTAIN?

Bioart-Thermal Painting / Cork and lime plaster is a product to be mixed just before use, the bucket contains a bag of thermal powder, a jar of natural resins and the instructions for use sheet. The applicator mixes everything with the correct amount of water and with a possible natural dye (the natural colorless version is gray, while a white dye is added to obtain the white thermal paint) The adhesion primer, always recommended, is to be buy separately

WHY CHOOSE A NATURAL THERMAL PAINTING / PLASTER?

Many thermal paints are available on the market that promise to solve the problem of condensation moisture and eliminate mold from the walls like Artimestieri's Bioart-Painting / Thermal plaster: why choose Artimestieri?
Because it is not only important to "solve the problem" but it is equally important to use healthy and natural products in our homes that do not contain petroleum derivatives, solvents and other hidden components: conventional thermal insulating paints are generally composed of ceramic microspheres in an acrylic resin derived from petroleum . Conventional thermal paint at best solves the mold problem but, due to its synthetic composition, it can compromise indoor air quality and limit the breathability and absorbency of the treated walls.
Bioart-Thermal Painting of Cork and Lime is an all-natural thermal paint for interiors composed of fine particles of cork and lime, while the Fissante contains: water, Tung oil, linseed oil, calcium resinate, borates, Turkish oil, casein, soy lecithin. Free from acrylic, vinyl, alkyd resins of petroleum origin, polyurethanes, isoaliphates and toxic substances in general.

THE BIOEDILE QUALITIES OF THERMAL PAINTING OF CORK AND LIME

 
1. Breathability of the heat-insulating paint important in order not to worsen the slow exchange of air that occurs also through the perimeter walls.

2. Absorbing power of the thermal paint which further limits the possibility of surface condensation which preferably takes place on waterproof walls: a typical example is the bathroom mirror which immediately condenses water vapor. Anti-condensation paint is such also thanks to the macroporous nature of the natural materials that compose it. If you find it difficult to choose among the countless bathroom paints: our advice is Artimestieri's Bioart-Painting / Intonachino Thermico for its remarkable ability to absorb water vapor.

3. Pleasantness to the sight and to the touch of natural thermal paint: a characteristic common to all bio-building materials. 

TO CARRY OUT THERMAL PERFORMANCES OF GREATER PERFORMANCE:

Thermal coating with thin cork sheets:
applying cork sheets to cold walls we obtain an excellent anti-condensation and anti-mold effect, thicknesses of 1/2/3/5/6/10 mm of supercompressed cork are available. Cork can be left exposed or covered with THERMOFINE thermal paint or plaster / skim coat. The use of TERMOFINE Bioart-adhesive / skim coat increases the thermal insulation power of the layering thanks to its cork content. Ready-to-use acrylic adhesives are also available for thinner thicknesses of 1 or 2 millimeters.

Thermal coat with blond cork panels:
from 1 to 10 cm thick: with the blond cork panels you make internal / external coats starting from 1cm thick. With these panels you can adapt the old (or new) houses to the current regulations on the thermal insulation of homes. To apply the panels, use Bioart-adhesive / cork smoothing, with plugs and anti-cracking mesh. The surface finish can be done with the same Bioart-adhesive / skim plaster in hydraulic lime, with Bioart-Rasatura Media / Fine. Outdoors we recommend Bioart-Rasatura Media colored with color on request, to obtain a colored, protective and breathable finish.

Thermal coat with brown cork:
from 5 to 30 cm thick: for insulation with even greater performance, we recommend the use of brown expanded cork that reaches thicknesses up to 30cm one-piece (the one-piece is always recommended for external cladding). The toasted cork panel is stable, robust and of high thermal insulation value. It is applied with Bioart-Adesivo / Rasante for cork, dowels and plaster mesh like the blonde cork panel.
