Rising damp treatment in Matosinhos
Matosinhos coastal damp differs from inland rising damp: salt crystals on sea-facing walls can read "wet" on a meter while the moisture source is atmospheric hygroscopicity, not groundwater. After the November–March storm cycle, we treat dozens of harbour-front units where owners painted over chloride efflorescence — paint failure returns within weeks. Damp proofing Matosinhos properties within 500 m of Praia de Matosinhos often pairs DPC injection (where capillary rise is real) with silane exterior treatment to cut salt uptake. Perafita and Guifões inland blocks revert to standard rising-damp physics without marine overlay. Leça da Palmeira shares our coastal protocol; see also our dedicated Leça page for marina-adjacent stock. We stock marine-grade replaster specs rated for BS 8102 salt exposure categories.
