Rising humidity: The simple and cost-effective DIY method for permanent wall repair
Step 1: Clean the Surface Before you begin, ensure the wall surface is clean and free of dirt, mold, or old mortar residue. Thoroughly clean the wall with a stiff brush and cleaning agent. Allow the surface to dry completely before proceeding to the next step.
Step 2: Prepare the Mortar Prepare the water-resistant or moisture-resistant mortar according to the manufacturer’s instructions. Be sure to wear protective gloves during this step to avoid skin irritation. Mix the mortar until smooth and lump-free.
Step 3: Applying the mortar. Use a trowel to spread the mortar evenly over the wall surface affected by rising damp. Make sure to completely cover the affected areas to create a protective layer that prevents water from penetrating through the wall’s pores.
Step 4: Finishing Once the grout is applied, smooth the surface with a brush and remove any unevenness. Allow the grout to dry completely according to the manufacturer’s instructions, usually between 24 and 48 hours.
