Why High-Quality Parging Materials Matter in Edmonton
Parging is an essential protective and aesthetic finish for exterior foundations, especially in a climate like Edmonton’s, where extreme temperature changes can cause structural damage. At J and J Coatings, we focus on using high-quality materials and expert techniques to ensure long-lasting results. This guide explains the materials we use, how they work, and why they matter.

What Are the Best Parging Materials for Long-Lasting Results?
Enhanced Portland Cement-Based Mortar: The Key to Strong Parging
To achieve durability and a smooth finish, we use a specially formulated Portland cement-based mortar that includes:
- Portland Cement – The backbone of the mix, providing strength and durability.
- Sand – Provides structure and enhances compressive strength.
- Lime – Increases workability and flexibility to withstand minor movements and temperature changes without cracking.
How Edmonton’s Climate Affects Parging Durability
Edmonton’s freeze-thaw cycles can cause parging to crack and deteriorate if not applied correctly. Choosing the right materials and techniques ensures that parging can withstand harsh winters without breaking down.
How We Prevent Cracking & Improve Parging Longevity
The Role of Specialized Additives in Parging
To combat environmental stress, we integrate specific additives into our parging mix:
Flexural Strength Enhancers
- Fibers – Reinforce the mortar, reducing the likelihood of cracking under stress or movement.
- Acrylic Modifiers – Improve flexibility while maintaining the integrity of the cementitious mix.
Shrinkage Reduction
- Shrinkage-Reducing Admixtures (SRAs) – Minimize drying shrinkage, reducing crack formation during curing.
- Water Reducers – Lower the water-to-cement ratio while preserving workability, improving strength and durability.
Weather Resistance
- Waterproofing Agents – Enhance resistance to moisture penetration, crucial for Edmonton’s snowy and rainy seasons.
- Air Entrainment Agents – Introduce tiny air bubbles into the mix to improve freeze-thaw resistance and minimize spalling and cracking.
Step-by-Step Guide to Proper Parging Application
Even the best materials won’t last if they’re not applied correctly. Here’s how J and J Coatings ensures high-quality results:
1. Surface Preparation
- Thorough Cleaning – The base wall is meticulously cleaned to remove all dirt, debris, and loose material. Older walls may require pressure washing or hand scraping.
- Priming – A bonding agent is applied to ensure a strong bond between the existing surface and the new parging layer.
A bonding agent is applied to ensure strong adhesion before parging.
2. Mixing the Mortar
- Consistent Ratios – Carefully measured mortar mix ensures uniform texture and performance.
- Additive Integration – Special additives are evenly mixed to enhance durability and workability.
3. Applying the Parging
- Graduated Layering Method – Applying mortar in layers helps build thickness without compromising adhesion or causing sagging.
- Expert Troweling Technique – Skilled artisans compact the mortar properly, eliminating air pockets and ensuring a uniform texture.
- Edge Crafting – Meticulous attention to edges and corners ensures clean, sharp lines, enhancing both the aesthetics and integrity of the work.

Common Parging Issues and How to Avoid Them
Why Does Parging Crack?
Parging can crack due to:
- Poor material formulation
- Improper application techniques
- Exposure to extreme weather conditions
To prevent this, we use high-quality materials, professional application methods, and reinforcement additives.
Can Parging Be Applied in Cold Weather?
Yes, but special measures must be taken:
- Using cold-weather additives to help curing in low temperatures
- Applying a thicker first coat to prevent premature drying
- Ensuring temperature control during application
How Can Homeowners Maintain Their Parging?
To keep your parging looking great and lasting longer:
- Inspect Annually – Look for cracks or damage and address them early.
- Keep It Dry – Ensure proper drainage around the foundation.
- Avoid Pressure Washing – Use a soft brush and mild detergent for cleaning.
