3-Step Process to
Achieving
Long-Lasting Protection

Step 1: Cleaning and Surface Preparation

Before any new coating can be applied, the surface of your home’s exterior must be thoroughly cleaned and prepared. This step is crucial because dirt, mould, and old paint can prevent the new coating from adhering properly to the walls, leading to premature failure or uneven application.
 
The Importance of Removing Dirt, Mould, and Old Paint:
Over time, your home’s exterior accumulates dirt, grime, and pollution particles, which can form a layer that interferes with the coating’s ability to bond with the wall. Additionally, mould and algae can grow in damp, shaded areas, weakening the surface and reducing its durability.
 
Old, peeling paint can also create an unstable surface that prevents the new coating from forming a strong, long-lasting bond. Removing these layers ensures that the protective coating can fully adhere to the clean, prepared wall surface.
 
Tools and Techniques Used:
Pressure Washing: One of the most effective methods for removing dirt, grime, and old paint is pressure washing. This high-powered water spray clears away loose debris and surface contaminants, leaving the walls clean and ready for the next steps.
Biocide Treatments: In areas where mould, mildew, or algae are present, professionals use biocide treatments to kill these harmful organisms. By applying biocides, the surface is sanitized, preventing future growth and ensuring that the new coating is applied to a mould-free surface.
Manual Scraping: For stubborn or peeling paint, manual scraping with wire brushes or scrapers may be required. This ensures that all loose material is removed, providing a stable foundation for the new coating.
 
Proper cleaning and surface preparation are essential for long-term results. Without this critical step, even the most advanced coatings will struggle to provide the protection and durability your home needs.

Step 2:
Restoration and Crack Repair

Once the surface is clean, the next step is to restore the integrity of the walls by addressing any cracks, imperfections, or damaged areas. Cracks, whether small or large, compromise your home’s defense against moisture and environmental damage, making it vital to repair them before applying the protective coating.

How to Address Cracks and Imperfections:
Small Hairline Cracks: These minor cracks can occur due to temperature changes, foundation settling, or normal wear and tear. They may seem insignificant, but if left untreated, they can widen over time and allow moisture to penetrate the walls.
Larger Cracks or Structural Damage: In cases where cracks are more severe, such as those caused by shifting foundations or extensive weather damage, more significant repair work may be required to restore the surface.

Filling and Repairing Techniques:
Polymer Resin Filling: For small to medium-sized cracks, professionals often use a high-quality polymer resin to fill and seal the gaps. This material is flexible, allowing it to expand and contract with the building’s natural movements, preventing future cracking.

Slush Coating: If there is significant damage to the surface, such as crumbling render or blown brickwork, a slush coating made of sand, cement, and latex is applied. This creates a smooth, even surface and restores the structural integrity of the wall.

Masking and Protection: During the restoration process, professionals carefully mask all windows, doors, and surrounding areas to protect them from dust, debris, and the coating application. Plants, lawns, and other landscaping are also covered with tarps to prevent any accidental damage.

By properly repairing cracks and imperfections, the wall is restored to a smooth, even surface that is ready for the protective coating. This step ensures that the coating will adhere evenly and last for many years.

Step 3: Applying the Protective Coating

With the walls cleaned and restored, the final step is to apply the protective coating. This stage is where the long-lasting benefits of professional-grade coatings truly come into play. The key to success here lies in the application process itself, ensuring that the coating adheres uniformly and forms a strong, durable bond with the surface.

Primer Importance:
Before the main coating is applied, a primer is essential for creating a solid base. The primer acts as a bonding agent between the wall surface and the final coating, ensuring that the top layer adheres properly and maintains its durability over time.

Uneven Porosity: Many exterior surfaces, especially older or previously painted walls, have areas with uneven porosity, meaning some parts absorb more paint than others. The primer helps to create a uniform surface, preventing uneven absorption and ensuring a consistent finish.

Strengthening the Bond: By applying a specially formulated primer, the bond between the wall and the protective coating is significantly strengthened, which is critical for long-term performance.

How Professional Application Ensures an Even, Durable Finish:
Spraying for Uniformity: Professional wall coatings are typically applied using high-pressure spraying equipment. This method ensures that the coating is evenly distributed across the surface, covering every inch of the wall with a smooth, consistent layer. Spraying also allows the coating to penetrate into small crevices and hard-to-reach areas, providing full coverage.

Multiple Layers: For maximum protection, the coating is often applied in multiple layers. The first layer acts as the base, while additional layers enhance durability, thickness, and resistance to environmental factors like UV rays, rain, and wind.

Final Inspection: After the coating is applied, professionals conduct a final inspection to ensure that the entire surface has been properly covered and that the finish is smooth and uniform. Any areas that need touch-ups or additional coating are addressed before completing the job.

The result of this meticulous process is a durable, weatherproof, and aesthetically pleasing exterior that can withstand harsh environmental conditions for 15 years or more. By following these three essential steps—cleaning and surface preparation, restoration and crack repair, and professional application—your home’s exterior will be protected against the elements, ensuring long-lasting beauty and protection.
