How to Repair Parging

Parging is the process of applying a thin coat of mortar or cement mixture to the exterior surface of a masonry wall, typically to improve its appearance and provide protection against the elements. If you need to fix or repair parging, here are the general steps to follow:

1. Clean the surface: Start by removing any loose or damaged parging from the wall. Use a wire brush, scraper, or chisel to carefully chip away the damaged areas and create a clean surface for the new parging.
2. Prepare the mixture: Mix a batch of parging material according to the manufacturer’s instructions. Typically, this involves combining cement, sand, and water in the proper ratios. You can also add bonding agents or acrylic fortifiers to improve adhesion and durability.
3. Wet the surface: Before applying the new parging, dampen the wall surface with water. This helps create a better bond between the existing wall and the new parging material.
4. Apply the parging: Use a trowel to spread the parging mixture onto the wall. Start from the bottom and work your way up, applying a thin, even layer. If needed, you can build up additional layers to achieve the desired thickness. Make sure to press the parging firmly into the wall to ensure good adhesion.
5. Smooth and texture: Once the parging is applied, use a trowel or a parging float to smooth the surface and create the desired texture. You can match the existing texture of the wall or create a new texture depending on your preference.
6. Cure and protect: Allow the parging to cure according to the manufacturer’s instructions. This usually involves keeping it damp for a few days and protecting it from extreme weather conditions. Covering the parging with a plastic sheet or using a curing compound can help retain moisture during the curing process.
