What is Parging and How does it work?

What is Parging?

Parging is a cement coating applied to the foundation or exterior wall of a structure. It is used to create a smooth, uniform surface, which protects the underlying material from weather and other environmental damage. The process of parging includes the application of a mixture of sand, Portland cement, and water over the existing surface. This mixture is troweled onto the wall in even layers and allowed to dry before any additional wall treatment. It is an important part of building maintenance because it helps protect against water seepage and deterioration caused by extreme temperature changes, as well as providing aesthetic value.

Is it Necessary to Parge your Masonry?

Parging is an important part of maintaining the exterior of your home. But it may not be mandatory to parge your masonry. Yet, it is highly recommended because it protects the most vulnerable areas of your home’s exterior from weather damage and deterioration.

What are the Benefits?

Parged masonry structures can offer many benefits including:

Increased Protection

One benefit to parging is increased protection against water damage. It works by creating a barrier between the foundation wall and weather elements. This prevents water from seeping in and causing damage to the structure underneath, which can become a costly repair. It also provides extra insulation against cold temperatures, protecting your home’s interior climate and structural integrity during winter months.

Decorative Appeal

Parging can add decorative appeal to your home without costing a lot of money for renovations and repairs. Once you parge the wall, you may add paint or waterproofing for extra protection and curb appeal.

Improved Structural Integrity

One of the most important benefits is structural integrity. Parging helps to cover up any exposed mortar joints and cracks in the wall. This will help to strengthen the structure and keep it from deteriorating further.

Which Surfaces should be Parged?

You may parge a number of surfaces and some of them are:

Block Foundation Wall

Cement block foundation walls are recommended to receive a coating of cement over the exterior portion for additional protection against water intrusion and damage. Cement coatings on foundation walls will help keep them in good condition, preventing water seepage, cracking, and other types of wear and tear.

Retaining Walls

Parging is also ideal for use on old retaining walls. These walls are often exposed to harsh weather conditions due to their outdoor location. Parging is a relatively simple and cost-effective option, making it an attractive option for anyone looking to upgrade their retaining wall without spending too much money. The process starts by removing any loose material from the wall’s surface and filling any cracks or holes with mortar or patching compound.

Chimney

Smoke chamber parging is one very important task that should be an integral part of chimney safety. This process cleans, seals, and reinforces the smoke chamber in your brick chimney, which helps to ensure safe operation. When done correctly, it can help prevent smoking problems as well as other issues like water leaks or hazardous creosote build-up.

Is Parging Repairable?

Yes, parging repair is possible. Over time, the material may start pulling away from the wall due to the expansion and contraction of moisture levels in its environment. Fortunately, these damages can be repaired. A skilled mason with experience in this particular type of work can fix these issues.

The mason will use specific techniques and materials, filling in any gaps and securing loose material back onto the wall. The process usually involves chipping away any loose material, cleaning and patching any cracks, and then applying a new layer of parging mix. It’s important to use quality material that will withstand the elements and resist damage in cold weather.

Let the Professionals Handle the Parging

Parging is a specialized skill and should not be attempted by the homeowner. It is best to leave this job to a skilled mason with expertise in applying it correctly. Applying parge incorrectly can trap moisture between the parge and the wall, causing further damage and costly repairs. A qualified mason can ensure that your walls are properly sealed against moisture, preventing future problems. So, trust your local masonry company to handle your project for optimal results. Remember, not all surfaces will require parging, so it’s important to have a professional inspect the area first before any work is done.
