Rising damp is a common problem in many homes, especially in older or poorly built ones. It occurs when ground water rises through walls, causing stains, mold and structural damage over time.

Fortunately, there are some DIY methods that can help solve this annoying problem without having to resort to expensive professional interventions. In this guide, we will show you the easiest and fastest method to eliminate rising damp from walls .

Materials needed:

Water-repellent mortar or anti-humidity mortar
Spatula
Brush
Protective gloves
Dust mask (optional, but recommended for safety)

Step 1: Surface Cleaning Before you begin, make sure the wall surface is clean and free of dirt, mold or old mortar residue. Use a stiff brush and cleaner to thoroughly clean the wall. Let the surface dry completely before proceeding to the next step.

Step 2: Preparing the mortar Prepare the water-repellent or moisture-proof mortar following the manufacturer’s instructions. Be sure to wear protective gloves during this step to avoid skin irritation. Mix the mortar until you obtain a smooth, lump-free consistency.

Step 3: Applying the mortar Using the trowel, spread the mortar evenly on the surface of the wall affected by rising damp. Make sure to completely cover the affected areas, creating a protective layer that prevents water from penetrating through the pores of the wall.

Step 4: Finishing Once the mortar has been applied, use the brush to smooth the surface and eliminate any irregularities. Allow the grout to dry completely according to the manufacturer’s directions, which usually range from 24 to 48 hours.
