We carry out waterproofing in Vilanova i la Geltrú. We visit the property, assess the work, give you a clear price, and start. Homes on the seafront have specific problems requiring extra treatment. Saltpetre settles on the wall and, with humidity, migrates inwards. When we paint over it, the salts continue their path and peel the new paint within months. The solution is washing with specific chemicals before painting, neutralization, and applying a siloxane-type paint that allows the wall to breathe without letting water in.

How we work

The second step is priming. We apply a specific sealing primer that penetrates the substrate and creates a uniform base for the final paint to adhere to. Without correct priming, the final paint may not adhere well and peel off quickly. This is the step most often skipped in quick repaints but has the biggest impact on durability. The third step is applying the final paint. For large facades, we use airless spray guns for a fast, uniform finish. For terraces and detailed areas, a good quality roller. We always apply two cross coats (the first vertical, the second horizontal) to ensure even coverage without brush marks. The first step is substrate diagnosis. If the existing paint is well adhered, we cover it. If it is peeling, we remove it completely with a spatula and sander, leaving the substrate clean. If there are structural cracks (not superficial), we treat them with elastic filler that accommodates minor building movements without cracking again. If there are saltpetre stains or white efflorescence, we remove them with specific chemicals and neutralize before painting.

When to call for waterproofing in Vilanova i la Geltrú

Damp due to leaks requires extra treatment. If water is entering from the roof, the roof must be repaired first. If it's rising damp from the ground, it requires chemical barrier injection. Painting over without treating the source is always a waste of money. Damp treatment is a separate issue. The Costa Blanca has serious problems with rising damp in ground floors and leaks in flat roofs. We apply waterproofing mortars, barrier injections against rising damp, and breathable coatings that let the wall breathe without the paint flaking. Matt and satin emulsion paint for interiors, synthetic enamel for doors and skirting boards, textured finishes on old ceilings if the client wishes to keep them, single-coat paint for exteriors and facades, and elastic coatings for walls with structural cracks. We work with professional brands like Procolor, Tollens, Bruguer, and Titan, depending on the surface type.

Materials and brands

Official manufacturer warranty for the paint plus our coverage on labour. Have you bought a property in the area and the facade or terrace has yellowish, peeling paint or whitish stains? It's not due to poor quality of the original paint. It's due to the harsh exposure conditions of the area. The Costa Blanca combines four factors that destroy standard exterior paints: Intense and constant sun, more than 300 days a year of direct UV radiation. Sea saltpetre that deposits on surfaces near the coast. Rare but torrential rains that wash away layers. And Sahara dust that embeds itself between the pigments. An economical white paint resistant to UV will last three summers in these conditions. A specific paint for coastal climates with enhanced UV filter will last 8-10 years with a good appearance. We check the facade's condition and choose the appropriate painting system for the material and exposure.

Indicative price

The price for waterproofing in Vilanova i la Geltrú typically ranges between €170 and €5000. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. The most common mistake is repainting a facade with interior paint or cheap, large-surface exterior paint. It works the first year but visibly degrades by the second. Investment in specific exterior paint with acrylic or silicone resins, quality UV filter, and impact resistance is necessary. The price difference per litre between economical and professional paint is relatively small. The difference in years of durability more than compensates.

Frequently asked questions

How long does it take to paint a whole home?
An 80-100 m² home with a crew of 2 people takes 3-4 days to paint with two coats. If walls need repair, smoothing of textured finishes, or damp treatment beforehand, add 2-3 days.
Do you paint exterior facades at height?
Yes, up to the second floor with our own lifting platforms. For taller buildings, we work with specialized companies with vertical work permits.
Do you treat rising damp?
Yes, using chemical barrier injection methods and waterproofing mortars. We guarantee the treatment for 5 years. Painting over untreated damp will never work, it always returns.

Yes, bathrooms and kitchens up to 15 m² we do fully: demolition, plumbing, electricity, tiling, sanitaryware, and painting. For larger renovations, we refer to a specialized construction partner.
