[vc_row kd_background_overlay=”default” kd_background_image_position=”vc_row-bg-position-top”][vc_column][vc_column_text]Anyone who suddenly sees white, fluffy spots appearing on walls or ceilings is probably alarmed<\/strong>. Yet it’s a common phenomenon in Flemish homes. It looks like a type of mold that spreads rapidly and forms unsightly stains on the walls. <\/p>\n

But what many don’t know: that so-called “white mold” is actually not real mold, but a clear symptom of an underlying moisture problem.[\/vc_column_text][vc_empty_space][\/vc_column][\/vc_row][vc_row content_placement=”middle” kd_background_overlay=”gray-color” kd_background_image_position=”vc_row-bg-position-top” css=”.vc_custom_1719408216266{margin-bottom: 50px !important;border-bottom-width: 4px !important;padding-top: 25px !important;padding-right: 50px !important;padding-bottom: 25px !important;padding-left: 50px !important;background-color: #f7f7f7 !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;border-bottom-color: #8dc63f !important;border-bottom-style: solid !important;}”][vc_column]

What is that White, Fluffy Deposit Actually?<\/h2>\n

The white, hairy layer you see is not mold, but saltpeter.<\/strong> It’s a substance that forms through a chemical reaction between moisture in the wall and certain minerals in the building material.<\/p>\n

As soon as groundwater or rainwater moves through the walls, those salts dissolve in that water. When the moisture evaporates at the surface, the white crystals remain in the form of a powdery, hairy layer. <\/p>\n

Although saltpeter itself is not living mold<\/strong>, it does serve the same role as an alarm signal: your walls are dealing with moisture and that problem needs to be addressed.<\/p><\/blockquote>\n

How Do You Recognize White Saltpeter Deposits?<\/h2>\n

It’s important to distinguish saltpeter deposits from ordinary mold, so you know which treatment is needed.<\/p>\n
