We do waterproofing in Montcada i Reixac. We visit the property, assess the job, give you a clear price, and start. Homes on the frontline of the sea have specific problems requiring extra treatment. Saltpetre deposits on the wall and, with moisture, migrates into the substrate. When you paint over it, the salts continue their path and peel the new paint within months. The solution is washing with specific chemicals before painting, neutralisation, and application of a siloxane-type paint that allows the wall to breathe without letting water in.

How we work

The first step is substrate diagnosis. If the existing paint is well-adhered, we cover it. If it's flaking, 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 re-cracking. If there are saltpetre stains or white efflorescence, we remove them with a specific chemical product and neutralise before painting. The second step is priming. We apply a specific sealing primer that penetrates the substrate and creates a uniform adhesion base for the final paint. Without the correct primer, the final paint may not adhere well to the substrate and peel off soon. This is the step most often skipped in quick repaints, but it has the biggest impact on durability. The third step is applying the final paint. For large facades, we use airless sprayers for a fast, uniform finish. For terraces and detail areas, we use good quality rollers. We always apply two cross coats (the first vertical, the second horizontal) to ensure even coverage without marks.

When to call for waterproofing in Montcada i Reixac

Damp from 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, chemical barrier injection is needed. Painting over without treating the source is always a waste of money. A full tiling of a 6 m² bathroom with medium-range materials, 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 frontline of the sea, penetrates exterior walls. The white efflorescence you see under the render are salts rising with moisture. Painting over without treating the source wastes time and money; the new paint will peel off in 6-8 months. The correct process is de-crusting, neutralising the salts with specific chemicals, and only then applying the paint system.

Materials and brands

Procolor Termik, Tollens Aquastop, Bruguer Sol. Specific for exterior with UV filter. Official manufacturer warranty 8-10 years. 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. You need to invest in specific exterior paint with acrylic or silicone-based resins, a quality UV filter, and impact resistance. The cost difference per litre between the cheap and professional option is relatively small. The difference in years of durability far outweighs it. We check the facade's condition and choose the appropriate paint system for the material and exposure.

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, plaster smoothing, 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 specialised 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 without treating the moisture will never work; it always returns.
Do you do small full renovations?
Yes, for bathrooms and kitchens up to 15 m² we do them completely: demolition, plumbing, electricity, tiling, sanitary ware, and painting. For larger renovations, we refer you to a specialised construction partner.
Do you cover and protect the house before painting?
Of course. We cover floors with hardboard or thick plastic, protect sockets and skirting boards with tape, and move light furniture. Bulky items are moved from the centre of the room.
Is the quote free?
Yes, free and without obligation. A prior visit to measure and check wall condition. Detailed quote by item within 24-48 hours.
