How to Treat Rising Damp with PROSEAL Damp Treatment Solutions – A Nigerian Success Story A few years ago, PROSEAL stepped into the Nigerian construction industry with a clear mission: to make reliable, high-quality waterproofing solutions accessible and affordable for everyone. Back then, waterproofing was seen as a luxury, reserved for the wealthy due to the high costs of imported products and the lack of technical knowledge locally. We launched with just two products—PROSEAL Super Add and PROSEAL Damp Cure—and slowly began changing the narrative around waterproofing in Nigeria. Today, PROSEAL is a household name in the Nigerian construction sector, offering a comprehensive range of damp treatment solutions tailored to address the unique challenges we face here—whether it’s poor drainage systems, failed damp proof courses (DPC), substandard materials, or bad workmanship. Understanding Rising Damp in Nigeria Rising damp is a common problem in many Nigerian homes, especially during the rainy season when groundwater levels rise. This occurs when water from the ground travels upwards through the pores of masonry walls via capillary action. As this moisture evaporates, it leaves behind hygroscopic salts (nitrates and chlorides), which attract even more moisture from the air, worsening the damp problem over time. Buildings without a proper Damp Proof Course (DPC), or where the DPC has failed due to poor installation or materials, are especially vulnerable. While quick fixes like improving drainage might help temporarily, they don't offer lasting protection. That’s where PROSEAL steps in. The PROSEAL Damp Treatment Range To effectively combat rising damp, PROSEAL offers four specialized damp treatment products, each designed for different construction needs and scenarios: 1. PROSEAL DPM Liquid Membrane Unlike traditional sheet membranes, PROSEAL DPM Liquid Membrane is applied directly at the DPC stage to create a seamless, durable barrier against rising damp. In Nigeria, where the lack of proper installation training and knowledge often leads to poorly installed sheet membranes, the liquid membrane offers a more reliable, easier-to-apply solution. It ensures that your foundation stays protected from day one. 2. Two-Component Admixtures (Liquid & Powder) This powerful combination penetrates deeply into the masonry, lining capillary pores to form a robust, long-lasting chemical DPC. Ideal for severe damp issues where moisture has infiltrated deeply into walls, the kit includes 10L of liquid and 15kg of powder, covering extensive wall areas with ease. 3. Single-Component Powder (PROSEAL Damp Cure) For less severe damp problems or routine maintenance, PROSEAL Damp Cure offers a simple yet highly effective solution. This 20kg powder is easy to apply and delivers strong, lasting protection against rising damp—perfect for both professionals and DIY enthusiasts. 4. PROSEAL Damp Fix Skim Plaster After treating the damp, you'll want to restore your walls to a clean, smooth finish. PROSEAL Damp Fix Skim Plaster not only provides that professional look but also prevents salt migration during the drying process, ensuring that damp doesn’t return. It’s the final step for a flawless, damp-free wall. How to Use PROSEAL Damp Treatment Products 1. Identify the Source of Damp Inspect your building for failed DPCs, high ground levels, or poor drainage systems that may be causing rising damp. 2. Apply the PROSEAL DPM Liquid Membrane at the DPC Stage For new constructions, apply PROSEAL DPM Liquid Membrane to create a seamless protective barrier that prevents rising damp from the start. 3. Treat Existing Damp with Two-Component Admixtures or Single-Component Powder For existing structures, use the two-component admixtures for severe damp or the single-component powder for moderate cases. 4. Re-Plaster with PROSEAL Damp Fix Skim Plaster After treating the walls, apply PROSEAL Damp Fix Skim Plaster to achieve a smooth, long-lasting, and salt-resistant finish.
