We carry out plastering and rendering in Cerdanyola del Vallès. We visit the property, assess the work, give you a clear price, and start. Specific to homes on the front line of the sea. Saltpetre deposits on external walls, penetrating with moisture. It emerges when evaporating, forming white or bluish stains that peel paint from the inside. The treatment involves washing with specific chemicals, neutralising remaining salts with anti-efflorescence products. Application of a siloxane-type paint system that allows the wall to breathe without letting water in.
It depends on the linear metres of wall affected. We provide a fixed quote after a diagnostic visit, with no obligation.

Chemical injection, exterior waterproofing, breathable render, or ventilation depending on the diagnosis.
Yes, specific paint system for damp walls: salt-blocking primer, breathable microporous paint that allows the wall to breathe. There are four types of damp we commonly see on the Costa Blanca, each with a different cause, diagnosis, and treatment. Confusing them inevitably leads to ineffective treatments and wasted money. That's why we always start with a technical diagnostic visit before quoting anything. The difference between treating damp correctly or poorly changes the durability of the result between five years and six months. This is damp that rises from the ground through the walls due to the capillary action of porous materials. It appears as a damp stain on the ground floor up to a height of one metre from the floor, often with white efflorescence (salts that crystallise as the water evaporates). It's typical in old ground-floor properties, especially in areas with a high water table near the sea.

Penetrating damp: stain descends from the ceiling or high corners, coincides with rain. The treatment involves adequate ventilation combined with interior thermal insulation. Installation of bathroom and kitchen extractors with the correct flow rate, cross-ventilation of rooms. In serious cases of very cold walls, application of interior insulation with projected cork or sandwich panels. Without solving the cause (vapour that cannot escape), any applied paint will blacken again.
