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

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

Step 3: Applying the mortar Using the trowel, spread the mortar evenly over 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 grout is applied, use the brush to smooth the surface and remove any irregularities. Allow the grout to dry completely according to the manufacturer’s instructions, which usually range from 24 to 48 hours.

Step 5: Monitoring Once the mortar is completely dry, periodically check the wall to ensure that the rising damp has been effectively stopped. If you notice the reappearance of damp spots or signs of mold, you may need to repeat the process or consider other solutions.

This DIY method can help significantly reduce rising damp in walls , but it is important to understand that further interventions may be necessary, especially if the problem is particularly severe or if the structural conditions of the home require it.

If you are unsure how to address the problem or if the damp persists despite your best efforts, it is advisable to consult a professional with experience in damp and building issues.

Paying attention and taking timely action can help preserve the integrity of your home and maintain a healthy and safe environment for you and your family.
