Give your UK garage a makeover! Learn to paint pebbledash for a beautiful, lasting finish. Tips & FAQs included. 🇬🇧

Pebbledash, a popular exterior finish in the UK, known for its durability and unique texture, can present a challenge when it comes to painting. This guide aims to demystify the process, providing step-by-step instructions and expert tips to achieve a professional-looking finish on your pebbledash garage. Whether you're looking to refresh the existing colour or embark on a complete transformation, follow these essential steps.

Understanding Pebbledash

What is Pebbledash?

Pebbledash is a type of wall covering typically used on the exterior of homes. It consists of small pebbles or stones ('dashing') thrown onto a wet layer of render, creating a textured finish. This method offers weather resistance and durability, making it a favoured choice in variable climates like the UK's.

Benefits of Painting Pebbledash

  • Aesthetic Appeal: Painting pebbledash can significantly improve the appearance of your garage, enhancing curb appeal.
  • Protection: A fresh coat of paint adds an extra layer of protection against the elements, extending the life of the pebbledash.

Preparing to Paint Pebbledash

Choosing the Right Paint

Select a paint specifically designed for exterior use on pebbledash surfaces. Masonry paint is ideal, offering durability and adherence to textured surfaces. Opt for a breathable formula to prevent moisture from getting trapped within the pebbledash.

Tools and Materials Needed

  • Masonry paint
  • Primer (if necessary)
  • Stiff-bristled brush
  • Roller with a long nap
  • Extension pole
  • Paintbrushes for touch-ups
  • Ladder
  • Pressure washer or hose

Preparing the Surface

  1. Clean the Surface: Use a pressure washer or hose to remove dirt, algae and loose pebbles. Allow the surface to dry completely.
  2. Repair Any Damage: Fill in cracks or gaps with a suitable exterior filler. Let it cure as per the manufacturer's instructions.
  3. Prime if Necessary: Apply a primer designed for masonry if the pebbledash is highly porous or if significant repairs were made.

Applying the Paint

  • Start with a Test Patch: Before fully committing, apply paint to a small, inconspicuous area to ensure good adhesion and colour satisfaction.
  • Use a Roller for Large Areas: A long-nap roller is effective for covering the textured surface. Use an extension pole to reach higher areas safely.
  • Brush for Edges and Details: Use a paintbrush for precision around doors, windows and corners.
  • Apply Multiple Thin Coats: Rather than one thick coat, apply two or more thin coats, allowing adequate drying time between applications.

Tips for a Professional Finish

  • Paint in mild, dry weather to ensure proper drying.
  • Avoid painting in direct sunlight, which can cause the paint to dry too quickly and unevenly.
  • Ensure consistent coverage by working in small sections.

Maintenance and Care

Once painted, your pebbledash garage will require minimal maintenance. Regularly check for and repair any cracks or peeling to maintain the integrity of the paint and pebbledash underneath. Cleaning the surface annually with a gentle wash will keep it looking fresh and vibrant.


Painting a pebbledash garage can rejuvenate the exterior of your home, adding both aesthetic and protective benefits. With the right preparation, materials and techniques, you can achieve a professional-quality finish that will last for years to come.

FAQ: Painting Your Pebbledash Garage

Pebbledash painting can refresh your garage's appearance and improve its weather resistance. However, it requires more effort and maintenance compared to smooth surfaces. Consider your DIY skills and desired outcome before starting.

With proper application and quality materials, painted pebbledash can last 5-7 years before requiring a repaint.

Use a high-quality, micro-porous masonry paint specifically designed for exterior use. Avoid standard paints as they might not adhere well.

Yes, using a masonry primer designed for pebbledash is highly recommended. It improves paint adhesion and ensures a more even finish.

Due to the textured surface, expect to apply at least two, possibly three, thin coats of paint for complete coverage.

While technically possible, using a spray gun for pebbledash is not generally recommended. It can be difficult to achieve even coverage and can lead to overspray and drips. A brush and roller offer more control and ensure proper paint penetration into the nooks and crannies.
