Is it cheaper to plaster or render?

Internal plastering usually costs less per square metre than external rendering. Rendering involves more materials and preparation work which pushes the price higher. The scope of the job makes a big difference too.

Do plasterers do render?

Yes — an experienced plasterer works on both internal and external surfaces. Our team covers everything from interior skimming to full K Rend silicone rendering systems on outside walls.

Does rendering reduce house value?

No — quality rendering improves kerb appeal and protects the structure, both of which buyers respond positively to. It is failing or poorly applied render that causes problems at valuation.

How much does rendering usually cost?

It depends on property size, the system used, and the condition of the existing surface. We provide a free written quote after every site visit with no hidden costs involved.

Does render make a house damp?

It can if it is non-breathable or badly applied. Silicone systems like K Rend are designed to let moisture vapour escape while keeping rainwater out. Done correctly render prevents damp rather than causing it.

Why are plaster walls not used anymore?

Boarding and skimming over plasterboard is quicker and more cost effective for most modern builds. Lime plaster is still used on older and heritage properties where breathability really matters.

Understanding K Rend

First things first, what exactly is K Rend? Simply put, it’s a popular polymer-modified render designed to protect your home, while also giving it a clean, finished look. If you’d like the full breakdown of what K-Rend is made of, its history, and its different finishes, see our comprehensive guide to K-Rend.

Benefits of K Rend:

Weather resistant: Keeps your property safe against harsh elements.
Breathable: Reduces moisture build-up, protecting your walls for years to come.

However, even this durable material needs a refresh after a while. That’s where painting comes in!

Can You Paint K Rend?

Yes, you can paint K Rend — but it depends on its condition.

Factors to Consider:

Surface Age & Condition: Is the render older and showing signs of wear? It might be the perfect time for a facelift.
Cleaning Needs: Dirt or algae must be thoroughly removed for proper paint adhesion.
Structural Integrity: Check for cracks or loose render — these need fixing first!

If the render is clean and damage-free, painting can give your home a rejuvenated look with added protection.

Benefits of Painting K Rend

Painting K Rend doesn’t just improve your property’s appearance — it unlocks some serious advantages:

A Fresh Look: Choose colours that match your vibe or completely switch up your property’s style.
Added Protection: Paint acts as a shield, further enhancing the render’s weather resistance.
Cost Efficiency: Painting your existing render is budget-friendly compared to a total replacement.

Challenges of Painting K Rend

Painting K Rend isn’t without its challenges, but with the right prep work (and mindset!), you’ll be set for success:

Risk of Peeling or Cracking: This mostly happens if the surface isn’t prepped correctly, so don’t skip steps like cleaning and priming.
Choosing the Right Paint: Make sure to use breathable masonry paint specifically formulated for rendered surfaces.

Focus on doing it right the first time to avoid headaches down the road!

How to Stop K-Rend Turning Green (Algae & Mould)

One of the most common issues homeowners face with K-Rend — painted or unpainted — is green algae staining, particularly on north-facing walls or areas shaded from direct sunlight. This happens when moisture sits on the render’s surface for extended periods, allowing algae spores to take hold.

Prevention tips:

Check guttering and drainage regularly — overflowing gutters are one of the most common causes of algae staining, as they keep specific areas of the wall consistently damp.
Trim back nearby vegetation that shades walls or restricts airflow, since shaded, poorly ventilated areas are far more prone to algae growth.
Use a silicone-based masonry paint when repainting, as these formulations are more resistant to algae and dirt pickup than standard acrylic paints.
Clean affected areas promptly with a suitable render/masonry cleaner or a soft-bristle brush and water — avoid harsh pressure washing, which can damage the render’s surface texture.

If green staining keeps returning to the same area despite cleaning, it’s usually a sign of an underlying moisture issue (such as a leaking gutter or poor drainage) that needs addressing at the source, rather than repeatedly cleaning or repainting the symptom.

Preparation Tips for Painting K Rend

Are you ready to make your render shine? Follow these steps before painting:

1. Inspect the Surface Ensure the wall is properly cured (if new), clean, and dry.

2. Clean Thoroughly Remove dirt, stains, and algae with a soft brush or pressure washer. Eco-friendly cleaners are a great option here!

3. Repair Damage Fill any cracks or imperfections with appropriate filler and allow it to dry.

4. Prime the Surface Priming ensures your paint sticks well and lasts longer. Use a primer specifically made for K Rend or masonry surfaces for the best results.

Choosing the Right Paint for K Rend

Not all paint is created equal when it comes to rendering!

Use Breathable Masonry Paint: This prevents moisture buildup while protecting your render.
Weatherproof and UV-resistant: Look for paints that can withstand the elements for years.
Eco-Friendly Options: Choose paints with low VOCs to stay sustainable while achieving a vibrant finish.

Pro tip? Opt for trusted brands known for quality masonry paint to guarantee great results — and where possible, a silicone-based masonry paint rather than standard acrylic, since silicone formulations resist algae and dirt pickup significantly better over time.

Step-by-Step Guide to Painting K Rend

Here’s your roadmap to a smooth painting process:

Gather Your Tools: Paint, primer, roller, brushes, paint tray, and a ladder (if needed).
Apply Primer: Begin with an even coat of primer and allow it to dry completely.
Start Painting: Use a roller for large surfaces and a brush for edges or detailing.
Even Coverage: Apply paint in thin, even layers to avoid drips or streaks.
Add Coats Wisely: Two coats usually provide a solid finish. Allow proper drying time between layers.

Cleaning & Maintaining Painted K-Rend

Your hard work deserves to stand the test of time! A little routine maintenance goes a long way toward keeping painted K-Rend looking fresh for years.

Routine Cleaning: Gently clean painted surfaces once or twice a year to reduce dirt build-up and algae growth — a soft brush and water is usually sufficient.
Surface Checks: Inspect for cracks or peeling annually, particularly after winter, and touch up as needed before small issues develop into bigger repair jobs.
Weather Watch: Protect your render against harsh weather with timely touch-ups using high-quality, matching masonry paint.
Touch-Up Paint Tips: Keep a small amount of your original paint colour and batch number stored safely — this makes touch-up work far easier and ensures a consistent colour match, since paint batches can vary slightly over time.
Minor Crack Repair: Small hairline cracks can typically be filled with a flexible exterior filler before touching up with paint. Larger cracks, or render that sounds hollow when tapped, should be assessed by a professional, as this can indicate the render has debonded from the wall beneath.
