Parging is the process of applying a masonry-based mortar to the interior or exterior walls made of block, brick or stone. In some cases, parging is done simply to give a finished look to the structure. For example, concrete blocks and poured concrete walls often have a rough texture and may need parging to provide a smoother appearance. In other cases, this method protects a building and keeps mortar from failing. While parging is not a waterproofing agent, it can help keep water out of your house or business. This process is an economical solution with several benefits. If done incorrectly, parging can trap water between the exterior and the parge coat, which is why it is important to book an experienced contractor.

Along with giving your concrete floors a nice and smooth surface finish, parging offers the following benefits:

  • Insulation
    Parging can give your home additional protection and insulation for your foundation against the cold winter. A coat of parging will also keep the integrity of your foundation’s structure as it prevents water from freezing in the cracks and holes, which can lead to a host of other issues.

  • Protects against insects and critters
    Holes and cracks in your concrete invite tiny bugs, critters and other insects and rodents, such as mice, allowing them to enter through holes in your walls. While such pest infestation can be tough to eliminate and cause severe damage, parging is a cost-effective solution to avoid the situation.

  • Improves structural integrity
    Unaddressed cracks and holes in your foundation can quickly become big problems, leading to expensive repairs and unnecessary stress. Parging adds an extra layer of structural integrity by covering any existing cracks on the walls, preventing water from freezing in these holes.

  • Improves energy efficiency
    Parging your walls will make them stronger and reduce your energy usage by adding a layer of insulation. Covering small cracks in your exterior walls stabilizes indoor temperatures, improves your carbon footprint, and saves money on heating or air-conditioning bills.

  • Increases curb appeal
    Proper construction, maintenance and care can make your home the haven it needs to be for years to come. It will also make it more valuable whenever you decide to sell it. Protecting your home with a layer of parging can prevent damage from elements through the seasons and allow you to sell your home at a higher estimated value.

The parging process is as follows:


  • First, the area to be covered is thoroughly cleaned. Loose mortar, soot or any other dirt is scrubbed off using detergent. This is done to ensure that parging sticks well to the chimney.

  • The walls are rinsed, and deeply eroded bricks are chiselled and replaced. This is done to ensure that you don’t face problems in the future.

  • The walls are kept moist while applying a thick layer of mortar. It is crucial to be vigilant at this stage because if the mortar is not applied correctly on the damp walls and kept moist throughout the process, the mortar mix will spread unevenly and likely break.

  • The wall needs to dry for a day before the second coat is applied, which not be more than 3/8-inch thick. Skip the second coat if you are satisfied with the wall after only one coat.
