WALL RESTORATION

RISING HUMIDITY?

THE SOLUTION IS THE PETER COX® BARRIER SYSTEM !

The problem of rising damp in the walls is a constant presence in old or ancient buildings and can also occur in recent constructions.

At the root of this problem there are always two factors: the presence of water in the subsoil and the capillarity of the building material. All building materials and their binders have a dense network of microscopic channels inside which can absorb and transport water by capillarity, making it rise up into the walls. Another contributing factor to the phenomenon is the presence of dissolved salts in the water: if it reaches the surface and evaporates, the salts crystallize and form the classic white beards; if instead it occurs between the wall and the plaster, the pressure of the salts generates cracks, swelling and crumbling of the plaster.

Furthermore, the presence of humidity in the rooms gives rise to hygienic-environmental situations that are harmful to the people who work or live there, it worsens the microclimate by creating problems of thermal insulation, the formation of mold and greater energy consumption, moreover it is unpleasant from the point of aesthetic view.

THE PRINCIPLE FOR ELIMINATING RISING HUMIDITY

The Peter Cox System consists of the formation of a continuous chemical barrier at the base of the wall which, by reversing the wetting angle of the capillaries, stops the rising damp.
The products used, based on water-based formulations, are placed in the wall with slow diffusion through special transfusors, in such a way as to impregnate the entire section affected by the intervention, creating a stable hydrophobic treatment over time.

HOW TO ELIMINATE THE RISING HUMIDITY

The intervention must be carried out on still plastered walls, taking into account the height of the floors and always intervening 20 cm above the level of the highest altitude.

Following the intervention, the walls must be plastered up to a height of 50 cm above the existing stains, to facilitate the evaporation of the moisture they contain.

Once dried, it must be plastered again using transpiring macroporous plaster(MACROCOX), after applying an anti-salt impregnating agent (WATERPROOF/S).

PRODUCTS AGAINST RISING HUMIDITY

MACROCOX

Dehumidifying plaster based on natural hydraulic lime

DESCRIPTION
Premixed powder plaster based on natural hydraulic lime with additives that significantly increase the porous surface, thus allowing rapid and continuous evaporation of moisture.

USE
Its properties make it particularly suitable for the restoration of historic buildingsthat have walls damaged by the presence of residual humidity, saline efflorescence and condensation. Despite having good water repellency, Macrocox is not suitable for use on masonry in contact with the ground where there is a risk of lateral infiltration of water, unless the walls have been previously waterproofed with Coxosmotic osmotic cement.

COXOSMOTIC

Waterproofing cementitious grout

DESCRIPTION
Ready-to-use cement-based premix which, when mixed with water and Acrylcox, forms a grout. Applied to damp walls, it eliminates water infiltration, making both masonry and concrete surfaces waterproof.

USE
It is suitable for waterproofing any type of underground and non-underground construction, applicable both indoors and outdoors. Ideal for waterproofing concrete works and for containing water, such as tubs or reservoirs.

WATERPROOF/S

Impregnating agent for the treatment of masonry with saline outcrops

DESCRIPTION
Single-component liquid product which, together with the application of dehumidifying plaster, facilitates the evaporation of the moisture contained in the wall.
In this way, a hydrophobic layer is created on the walls that prevents the salts dissolved in the water from rising to the surface, maintaining the natural breathability of the supports.

USE
On surfaces previously plastered to the surface, or in any case without friable parts, Waterpoof / S will be applied in at least two coats, wet on wet.
The application can be done on a panel or with low pressure Airless, preferably on a dry substrate.

ACRYLCOX

Additive for osmotic mortars and slurries

DESCRIPTION
An emulsion of an acrylic polymer suitable for modifying the mechanical properties of mortars based on hydraulic binders. Mortars with Acrylcox additives improve resistance to compression, bending, traction and abrasion.
Acrylcox gives mortars excellent adhesion to the most common substrates; in addition, the acrylic nature gives it greater chemical inertness with good resistance to the aggressive action of solvents and color changes due to sun exposure.
Acrylcox is great for thin mortar applications, making it ideal for repair or patch work.

USE
It can be used as a casting grout, as a smoothing mortar and as an additive for osmotic mortars and grouts.
It is recommended to mix Acrylcox and water first and then add it all to the dry mix.
