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 the correct primer, the final paint may not grip the substrate well and will 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 quick, uniform finish. For terraces and detailed areas, we use a good quality roller. We always apply two cross coats (the first vertically, the second horizontally) to ensure uniform coverage without brush marks. The first step is substrate diagnosis. If the existing paint is well-adhered, we cover it. If it's peeling, we remove it completely with a scraper and sander, leaving the substrate clean. If there are structural cracks (not superficial), we treat them with elastic filler that accommodates small building movements without re-cracking. If there are saltpetre stains or white efflorescence, we remove them with specific chemicals and neutralise before painting.

Dampness from leaks requires extra treatment. If water is coming in 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 always wastes money. A full tiling of a 6 m² bathroom with mid-range materials costs between €1,800 including labour. Treatment of rising damp on a 4-metre wall, between €600 and €1,500. A 12 m² room with a plasterboard false ceiling and LED spotlights, between €700 and €1,200. Saltpetre, especially on the seafront, penetrates exterior walls. The white efflorescence you see under the render are salts rising with moisture. Painting over without treating the source is a waste of time and money; the new paint will peel off in 6-8 months. The correct process is to remove the salt, neutralise it with specific chemicals, and only then apply the paint system.

Procolor Termik, Tollens Aquastop, Bruguer Sol. Specific for exteriors with UV filter. Official manufacturer warranty 8-10 years. The most common mistake is repainting a facade with interior paint or inexpensive large-surface exterior paint. It works the first year but looks visibly degraded by the second. It's essential to invest in specific exterior paint with acrylic or silicone resins, a quality UV filter, and impact resistance. The difference in cost per litre between the inexpensive and professional options is relatively small. The difference in years of durability more than compensates. Official manufacturer warranty for the paint plus our coverage on labour.
