What is a Cement Renderer?

A Cement Renderer is a tradesperson who applies a traditional sand-cement render mix over masonry surfaces such as brickwork or blockwork. This type of render creates a durable, smooth or textured base layer ready for painting or final coatings.



Cement rendering is a key step after the external structure is complete and before painting or acrylic finishes.

What does a Cement Renderer do?

Your Cement Renderer will complete works according to your agreed scope of works.


Typically, a Cement Renderer will:

  • Clean and prepare surfaces (e.g., brickwork, blockwork) to ensure proper adhesion
  • Apply a scratch coat (base layer) and one or more top coats of cement render
  • Finish the surface with your requested texture: smooth, sponge finish, bagged, or trowelled
  • Control jointing to manage cracking risks
  • Protect adjacent surfaces such as windows and doors during rendering
  • Advise on curing and drying times before final painting

Barry's Toolbox

Always ask your renderer whether their price includes expansion joints and corner beads — these are critical for a long-lasting render job but are often left out of basic quotes.

What to look for in a Cement Renderer

When reviewing quotes, look for:

  • Experience with cement render: Different techniques compared to acrylic or textured renders
  • Preparation quality: Good surface prep and correct mix ratio is crucial for longevity
  • Attention to weather: Cement render must cure properly — avoid rush jobs during hot or rainy periods
  • Crack control practices: Control joints and mesh where needed
  • Clear warranty terms: Especially around workmanship and cracking

Before You Begin: What You’ll Need Ready

To get quotes from Cement Renderers, you’ll need:

  • Your external wall type (e.g., brick veneer, blockwork)
  • Estimated total m² of wall area
  • Preferred surface finish style (smooth, bagged, textured)
  • Access and scaffold details if applicable
  • Project schedule for rendering start

Average Timeframe

For this task, Pros typically provide quotes within 7-10 business days.

When Can I Expect Quotes?

Timeframes often vary based on demand and the type of Pro you're engaging (e.g. a plumber). If additional communication or clarification is needed is needed, the quoting process may take longer.

 

Don't be alarmed if you don't receive quotes or communication from any Build Buddy Pros straight away. Some work is more complex and the Pro may need time to comprehend your documents or scope of work. Depending on the job, there may even be some work required by the Pro before they are able to quote (e.g. a site visit might be required).

 

If the average timeframe indicated here has passed, and you have not received any messages or quotes, please feel free to contact the Build Buddy Expert Guidance and Support team for an update on quoting for this task.

Frequently Asked Questions

  • Is cement render painted after?

    Yes — cement render needs to cure fully, then it’s sealed and painted with an external membrane paint.

  • Can I apply cement render to lightweight cladding?

    No — cement render is designed for masonry surfaces. Lightweight panels usually require acrylic systems instead.

  • How long does cement render take to dry?

    Initial set in 24 hours, but full curing can take 7–10 days depending on thickness and weather.
