If you have rendered painted walls, you know how beautiful they can be. But you also know that they can be a bit of a challenge to keep clean. Render is a type of exterior wall finish that is made from a mixture of cement, sand, and lime. When it’s painted, it adds a touch of elegance and sophistication to your property. However, the paint on rendered walls can be more delicate and susceptible to damage than the render itself.

That’s why it’s important to use the right cleaning products and equipment when cleaning painted rendered walls. Using wrong products or techniques can damage the paint, leaving your walls looking dull and dingy. In this blog post, we’ll show you how to clean rendered painted walls safely and effectively, without damaging the paint.

Preparing Painted Rendered Walls for Cleaning

Before you begin cleaning, it’s important to take a few steps to prepare the area and protect your surfaces. Here are some tips for it:

• Protect nearby surfaces: Cover nearby surfaces, such as windows, doors, and plants, with plastic sheeting or tarps to protect them from the cleaning solution.
• Remove loose dirt & debris: Use a soft brush or broom to gently remove any loose dirt and debris from the walls. This will make it easier to clean the walls and help prevent the cleaning solution from becoming too dirty.
• Check for any damage: Inspect the walls for any signs of damage, such as cracks or chips in the paint. If you find any damage, it’s best to repair it before cleaning the walls.
• Choose the right cleaning products & equipment: Make sure you have the right cleaning products and equipment for the job. A mild detergent and a soft brush or sponge are usually sufficient for cleaning painted rendered walls. Avoid using harsh chemicals or abrasive tools, as these can damage the paint.

Cleaning Painted Rendered Walls

Now that you’ve prepared your external rendered walls for cleaning, it’s time to get started. Here are some step-by-step instructions:

• Apply the cleaning solution: Mix a mild detergent with water to create a cleaning solution. Apply the solution to the walls using a soft brush or sponge. Be sure to follow the manufacturer’s instructions for the detergent.
• Scrub gently: Use the brush or sponge to gently scrub the walls, working in small sections. Avoid using too much pressure, as this can damage the paint.
• Rinse thoroughly: After you’ve scrubbed the walls, rinse them thoroughly with clean water. Be sure to remove all of the cleaning solution from the walls.

If you’re not comfortable cleaning your painted rendered walls yourself, or if you don’t have the time or equipment to do it properly, consider hiring a professional render cleaning service contractor.

Tips for Avoiding Damage to the Paint

When cleaning painted rendered walls, it’s important to take care not to damage the paint. Here are some tips for avoiding damage to the paint during cleaning:

• Use the right cleaning products: Avoid using harsh chemicals or abrasive cleaners, as these can damage the paint. Instead, use a mild detergent and a soft brush or sponge.
• Use a soft wash system: A soft wash system uses low pressure and a mild cleaning solution to clean surfaces. This is a gentle and effective way to clean painted rendered walls without damaging the paint.
• Avoid high-pressure washing: as mentioned above high-pressure washing can damage the paint and render. It’s best to avoid it.
• Never use abrasive tools: Do not use abrasive tools, such as steel wool or wire brushes, as these can scratch and damage the paint.
• Be gentle: When scrubbing the walls, be gentle and use light pressure. Avoid scrubbing too hard, as this can damage the paint.

Test the cleaning solution on a small, inconspicuous area before using it on the entire wall. This will help you ensure that the solution won’t damage the paint.

Use a sealant to protect the paint. A sealant can help protect the paint from dirt, grime, and other contaminants, making it easier to clean and less susceptible to damage.

Repair any damage to the paint as soon as possible. If the paint is chipped or cracked, it’s more susceptible to damage. Repairing the damage as soon as possible will help prevent further damage and keep the paint looking its best.

Parting Words

Allowing layers of dirt to build up on exterior rendered walls not only looks unsightly but can allow deeper damage if left unchecked. Thankfully, with the right cleaning methods and solutions, you can strip away grime to restore painted renders to like-new condition again.
