Step 1: Cleaning the surface Before you start, make sure that the wall surface is clean and free of dirt, mold or residue of old mortar. Use a hard brush and detergent to clean the wall thoroughly. Allow the surface to dry out before proceeding to the next step.
Step 2: Preparation of the mortar Prepare water-repellent or anti-moisture mortar following the manufacturer's instructions. Be sure to wear protective gloves during this stage to avoid skin irritation. Mix the mortar until it obtains a homogeneous and lump-free consistency.
Step 3: Application of mortar Using the spatula, smoothly spread the mortar on the surface of the affected wall by the rising humidity. Make sure you completely cover the affected areas, creating a protective layer that prevents the water from penetrating through the pores of the wall.
Step 4: Finish Once the mortar is applied, use the brush to smooth the surface and eliminate any irregularities. Allow the mortar to dry completely according to the manufacturer's instructions, which usually ranges from 24 to 48 hours.
Step 5: Monitoring Once the mortar is completely dry, check the wall periodically to make sure that the rising moisture has been effectively blocked. If you notice the reappearance of moist spots or mold marks, you may need to repeat the process or consider other solutions.
This DIY method can help significantly reduce the rising moisture on the walls, but it is important to understand that further interventions may be needed, especially if the problem is particularly serious or if the structural conditions of the house require it.
If you’re not sure how to deal with the problem or if the humidity persists despite your efforts, it’s advisable to consult an experienced practitioner in issues related to humidity and construction.
Paying attention and intervening early can help preserve the integrity of your home and maintain a healthy and safe environment for you and your family.
