Is it worth re-rendering a house?

Yes, re-rendering a house is often worth it as it can significantly improve the appearance and weather protection of the property. It helps address cracks, damp issues, and worn finishes that may compromise the building’s integrity. Additionally, a fresh render can modernise the exterior and increase market appeal.

Can I render my house myself?

You can render your house yourself, but it’s a skilled job that requires the right materials, tools, and technique. Poor application can lead to cracks, moisture problems, or an uneven finish that may need to be redone professionally. Unless you have experience, hiring a renderer is usually the better option.

Does re-rendering a house add value?

Re-rendering can add value by improving curb appeal and protecting the structure from the elements. Buyers are often more attracted to homes that look well-maintained and modern. It also gives the impression that the property has been cared for, which can influence sale price.

How often should a house be re-rendered?

A quality render can last anywhere from 15 to 25 years depending on the materials used and exposure to weather. Regular inspections can help identify early signs of wear or damage before they become major issues. Re-rendering sooner may be necessary if there are cracks, damp patches, or flaking.

Do you need to remove old render before re-rendering?

Yes, if the existing render is damaged, cracked, or loose, it should be removed before applying new render. Rendering over an unstable surface can lead to adhesion problems and early failure. If the old render is sound and well-bonded, it may be possible to apply a new coat over it with proper preparation.

Choosing The Best Paint For Rendered Homes

Rendered homes are a popular choice across Australia thanks to their modern appearance, durability, and versatility. However, choosing the best paint for rendered homes is just as important as the rendering itself. The right paint protects your exterior from harsh sun, heavy rain, and temperature changes while enhancing the overall finish.

If you have recently completed a rendering project or are planning to refresh your exterior, here is what you need to know before selecting paint.

Why Paint Selection Matters for Rendered Surfaces

Rendered walls are porous. Without the correct coating, moisture can penetrate the surface, leading to cracking, bubbling, mould growth, or premature deterioration.

High quality paint does more than improve appearance. It acts as a protective barrier against:

UV damage
• Rain and moisture
• Mould and mildew
• Efflorescence
• Cracking from expansion and contraction

Choosing the best paint ensures your rendered home maintains a clean, professional finish for years.

Types of Paint Suitable for Rendered Homes

Acrylic Exterior Paint

Acrylic paint is one of the most popular options for rendered surfaces. It is flexible, breathable, and resistant to cracking.

Benefits include:
• Excellent adhesion to render
• UV resistance
• Flexibility to handle movement
• Long lasting colour retention

For most Australian homes, high quality acrylic exterior paint is a reliable and cost effective solution.

Elastomeric Paint

Elastomeric paint is thicker and more flexible than standard acrylic paint. It can bridge hairline cracks and provide superior waterproofing.

This type of paint is ideal if your render has minor surface cracking or if your property is exposed to heavy rain and coastal conditions.

Mineral or Silicate Paint

Mineral paints chemically bond with the render surface, making them highly breathable and durable. They are often used on lime based renders and heritage style homes.

These paints allow moisture to escape while still protecting the wall.

Factors to Consider When Choosing Paint

Climate Conditions

In Australia, exterior surfaces are exposed to intense UV radiation and sudden weather changes. Choose UV resistant paint designed specifically for exterior masonry and render.

Breathability

Render needs to breathe. Paint that traps moisture can lead to bubbling and peeling. Always choose breathable masonry paint suitable for rendered walls.

Surface Preparation

Fresh render must cure properly before painting. Cement render typically requires several weeks of curing time. Painting too early can cause adhesion problems and moisture issues.

Proper preparation includes:
• Cleaning the surface
• Repairing cracks
• Applying suitable primer or sealer

Colour Choice

Lighter colours reflect heat and are often recommended for rendered homes in hot climates. Dark colours absorb more heat, which may increase surface movement and stress.

Professional advice can help you balance aesthetics with long term durability.

The Importance of Quality Application

Even the best paint for rendered homes will fail if applied incorrectly. Surface preparation, primer selection, and correct application methods all affect the final outcome.

At Zaks Render, we understand how rendering and painting work together. A high quality render finish combined with the right paint system ensures a smooth, durable exterior that enhances your property’s value and street appeal.

When to Repaint a Rendered Home

You may need to repaint if you notice:
• Fading colour
• Hairline cracking
• Peeling or bubbling
• Water staining
• Chalky residue on the surface

Regular maintenance and timely repainting can extend the life of your render and prevent costly repairs.

Final Thoughts

Choosing the best paint for rendered homes is about more than colour. It is about protection, breathability, and long term performance. The right paint enhances your home’s appearance while safeguarding the render underneath.
