Your property’s walls take a beating every year. The UK weather, especially in Leicester, means constant rain, frost, and high humidity. Regular paint just can’t cope with this stress. It cracks, fades, and lets damp soak right into your brickwork or concrete. This leads to costly internal problems. You need a permanent solution that stops water damage from the cold.
Choosing the right exterior wall coating in Leicester is crucial. This specialist process creates a permanent, waterproof shield. We will guide you through the process, explain why it lasts so long, and show you the massive benefits for your commercial building.
The Threat of Damp on Your Building Fabric
Your walls are porous, meaning they absorb water like a sponge. When water gets in, it causes huge damage, especially during winter frosts. The water freezes, expands, and pushes the brick or render apart. This creates small cracks that allow even more water in. It is a constant cycle of decay.
This persistent damp is bad news for the structure and the interior. It ruins insulation, pushing your heating costs up. It also causes mold and mildew inside the building. You must stop water at the source. This is why a specialist exterior wall coating in Leicester is necessary, as it protects the core structure, not just the surface.
Specific Threats to Unprotected Walls
- Spalling and Cracks: Water freezing in the brickwork causes the surface to flake off. This is structural damage that is expensive to fix.
- Insulation Failure: Damp walls lose heat incredibly fast. Your heating system must work harder, wasting vast amounts of energy.
- Mold and Mildew: Internal damp air creates the perfect breeding ground for mold. This is a health hazard and requires costly professional remediation.
The Failure of Standard Paint
Standard masonry paint is decorative. It is not fully waterproof. It develops tiny hairline cracks quickly. These cracks let water seep in, trapping the moisture inside the wall. The paint then peels off, and the damp problem returns immediately.
Why Industrial Coatings Offer Superior Protection
Industrial wall coatings are fundamentally different from retail paint. They are much thicker. They use advanced resins, often silicone or polymer-based. These coatings form a breathable but fully waterproof membrane over the wall surface. This combination is essential for a long life.
The coatings are flexible. They move slightly with the building as it heats and cools. This flexibility prevents the hairline cracks that ruin standard paint jobs. Choosing the correct exterior wall coating in Leicester guarantees a waterproof seal for many years. It is an investment in your building’s future integrity.
Here are some Exterior Wall/House Coatings Contractors you can choose:
Key Differences in Wall Coatings
| Thickness | Very Thin (Low Solids Content) | 10 to 20 times thicker than paint. |
| Waterproofing | Water-Repellent (Will fail under pressure) | Fully Waterproof Membrane (Prevents water absorption). |
| Lifespan | 3 – 5 years | 15 – 20 years (Guaranteed). |
Breathability is Crucial
You might think a thick coating stops all moisture. True professional coatings are ‘micro-porous.’ This means they stop rain from coming in but allow moisture from inside the wall to evaporate out. This breathability prevents the damp from getting trapped inside the structure, which is vital for building health.
How Professionals Apply Wall Coating for Durability
The product itself is only half the story. The way the coating is applied is everything. You cannot just spray industrial coatings onto an old, dirty wall. The professional process is systematic. It is designed to prepare the wall for maximum adhesion and lifespan.
Specialists start with intensive cleaning and repair. They use powerful pressure washing to remove all biological growth, like moss and algae. Then, they repair all the cracks in the render or mortar. Only once the walls are structurally sound is the exterior wall coating applied.
What preparation is needed before an exterior wall coating?
Answer: Before applying an exterior wall coating in Leicester, the preparation must include high-pressure washing to clean the surface, treating any moss or fungus with a biocide wash, and filling all visible cracks and voids with a specialized flexible filler to ensure a perfect base.
The Spray Application Method
Professional application uses heavy-duty spray equipment. This is not like a small household sprayer. Industrial pumps apply the coating incredibly fast and evenly. This ensures the correct, guaranteed thickness across the entire wall. Rolling cannot achieve the same uniformity or speed.
The Importance of a Primer Coat
The first stage of application is always a special stabilizing primer. This primer seals the porous wall surface. It prepares the wall to accept the thick top coating. This step is essential for guaranteeing the long warranty period on the finished work.
Guaranteeing Protection, Value, and Appearance
The outcome of using a professional wall coating is a building that looks new and is protected for decades. The clean, modern look immediately increases your property’s value and curb appeal. You instantly remove the problem of recurring damp.
This long-lasting protection gives you peace of mind. You eliminate maintenance cycles for the next 15 to 20 years. This saves you significant money and time. Choosing the right exterior wall coating in Leicester is the final step in securing this valuable, long-term asset protection.
Long-Term Financial Benefits
Here are the key financial payoffs of professional wall coating:
- Zero Painting Costs: You avoid repainting for up to 20 years. This is a massive saving compared to painting every 3-5 years.
- Reduced Energy Bills: The dry, sealed walls insulate better. Your building holds heat more effectively, cutting your heating costs.
- Increased Asset Value: A 15-year guaranteed coating is a major selling point for any commercial property.
How long should an exterior wall coating in Leicester last?
A properly applied exterior wall coating using high-grade industrial materials should last and be guaranteed for a minimum of 15 to 20 years. This lifespan is much longer than the 3 to 5 years you get from standard exterior masonry paint.
Vetting Your Contractor
Always ask for proof of industrial spraying experience. Check their warranty carefully; it must cover both the material and the labor for the full 15 years. Choose a local specialist who understands the weather conditions specific to Leicester.
Conclusion
Protecting your property with a specialized exterior wall coating in Leicester is the smartest decision for long-term maintenance. You gain a durable, waterproof membrane that stops dampness, prevents structural decay, and dramatically cuts your energy bills.
This process is complex, requiring specific cleaning, repair, and industrial spray techniques. Do not rely on cheap paint that will fail quickly. Invest in a professional coating solution today. Secure your building’s integrity and appearance for the next two decades.
