When to Clean Your Render and When to Paint It

Maintaining the appearance and integrity of your building’s render is essential for aesthetic and structural reasons. Deciding whether to clean or paint your render depends on various factors, including the condition of the render, the type of contaminants present, and your property’s long-term goals. Here’s a guide to help you make an informed decision.

When to Clean Your Render

Presence of Organic Growth:

Algae, Moss, and Lichen: If your render is covered with organic growth such as algae, moss, or lichen, cleaning is often the best solution. These contaminants not only mark the appearance of the building but can also cause damage if left untreated. Soft washing with biocides like Algoclear removes these growths and prevents their recurrence​.

Dirt and Pollution:

General Grime: Renders can accumulate dirt and pollution over time, especially in urban areas. Cleaning with soft or steam cleaning can restore the render’s original look without repainting. This is particularly effective for high-quality renders like KRend and Parex​​.

Cost-Effectiveness:

Maintenance: Regular cleaning is more cost-effective in the long run than repainting. It preserves the render’s texture and appearance, delaying the need for more extensive and expensive interventions​​.

Environmental Considerations:

Eco-Friendly: Cleaning, especially with biodegradable solutions, is generally more environmentally friendly than repainting, which involves more materials and potential waste​.

When to Paint Your Render

Aesthetic Change:

New Look: If you’re looking to change the colour or freshen up the appearance of your building significantly, painting is the way to go. It allows for a complete makeover and can update the building’s style to match current trends.

Surface Damage:

Cracks and Chips: If the render has sustained physical damage like cracks or chips that affect its structural integrity, these should be repaired, and painting over them can provide an added layer of protection and uniformity. However, ensure that repairs are thoroughly dried and treated before painting.

Old and Faded Render:

Fading: Over time, exposure to the elements can cause render colours to fade. Painting can rejuvenate the look of an old and tired render, making it look new.

Comprehensive Protection:

Weatherproofing: High-quality exterior paint can add extra protection against weather elements. This is particularly useful for older renders that need additional weatherproofing to extend their lifespan.

Combining Both Approaches

Initial Cleaning Before Painting:

Preparation: Before painting, it’s crucial to clean the render to remove any dirt, algae, or moss. This ensures that the paint adheres properly and lasts longer. Before applying paint, cleaning beforehand can reveal any hidden damages that must be repaired​.

Regular Maintenance:

Long-Term Strategy: Combining regular cleaning with occasional painting can be an effective long-term strategy. Regular cleaning keeps the render in good condition while painting every few years refreshes its appearance and adds protection. This approach maximises the lifespan of the render and maintains the building’s curb appeal​.

Conclusion

Choosing to clean or paint your render should be based on the specific condition of your building’s exterior and your long-term maintenance goals. Cleaning is typically the first step, especially when dealing with organic growth or general grime, and it helps maintain the render’s original texture and appearance. On the other hand, painting is suitable for making aesthetic changes, covering repairs, or providing additional protection to older renders.
