The saltpeter: causes and effects

The saltpeter is one of the problems that can affect the masonry and coatings of a house. This problem results from accumulation of soluble salts on the surface of the walls which are transported by the ascending moisture to move to the outside.

When saltpeter  appears on the walls of a house is one of the most difficult diseases to solve. The saltpeter usually appears at the base of the walls and is characterized by a white spot and the swelling and disintegration of the coatings.

Why does saltpeter appear

The saltpeter is the result of deposition of the dissolved salts by moisture when the water evaporates from the wall leaving the solid matter entrained in the wall surface.

Somehow being the walls permeable to moisture it can exist from the ground or other location the dissolved salts are dragged to the point where it checks saltpeter.

Generally they are salts from soil or from the sands which have been used in the construction of the building containing the saltpeter (unwashed sand or river sand) and are always the result of the displacement of the moisture to the outside of the wall.

Effects of saltpeter

Although the immediate effect of saltpeter may appear to be unestetic  by unsightly stains on the walls, the reality is that the saltpeter can cause serious problems in the construction and significant reduction of its durability.

The effect of saltpeter walls may be visible with efflorescence "deposition of salts on the surface of the wall", but can also be invisible to Crypto efflorescence "deposition of salts on the inner walls."
Consider that these effects may be responsible for the structural deterioration, loss of decorative coatings, and changing living conditions and comfort. The most common of these effects are blistering and loss of wall coverings.

  • When I need always contact the paintor Jacinto. He is already part of the family, Jacintos father painted the house of my mother and grandmother. Later at the age Jacintos father left the paintings and was Jacinto who took his place. I can not be more pleased, because whenever I made paintings in my home and family I never got anything for pointing.

  • What really made me satisfactorily admired was the on-time arrival and the appearance of the team of painters. The team was duly identified and neither seemed to be painters since the uniform was spotless. After leaves for work we do not know what happened... When we came home everything was impeccable.
