Choosing a render colour is one of the biggest decisions in any external rendering project, since it will define how your home looks for years to come. Here are the main things to think about before you decide.
Through-Colour vs Painted Finishes
Modern systems such as K-Rend use through-colour technology, meaning the pigment runs through the entire thickness of the render rather than sitting on the surface as paint does. This means minor scuffs or chips don’t reveal a different colour underneath, and the finish won’t need repainting to keep its colour over time, unlike a painted...
If you’re planning an external render project, timing can make a real difference to how smoothly the job goes and how quickly your new render cures properly. Here’s what to consider when scheduling your rendering work.
Why Weather Matters During Application
Render needs stable, mild conditions to cure properly. Application in freezing temperatures can cause the render to crack or fail to bond correctly, while extremely hot, dry weather can cause it to dry too quickly, leading to shrinkage cracks. Persistent heavy rain during application can also wash out the finish before it’s...
Penetrating damp is one of the most frustrating problems facing UK homeowners, particularly those in exposed locations where driving rain batters external walls season after season. A question we hear regularly at SM Rendering is whether applying external render will put a stop to it for good.
The short answer is yes — when the correct render system is chosen and applied properly, rendering creates a continuous waterproof barrier across your external walls, preventing rainwater from working its way into the brickwork and through deteriorating mortar joints.
That said, rendering is not a universal...
Cracks in plaster are something almost every homeowner will encounter at some point, and reactions to them range from mild annoyance to genuine concern. While some cracking is a completely normal part of a building’s life, certain types of cracks are a warning sign of something that needs attention. Understanding why plaster cracks — and being able to tell the difference between harmless surface movement and a more serious structural issue — can save you time, money, and unnecessary worry.
Why Plaster Cracks: The Main Causes
Plaster is not a particularly flexible material. Once it has...
Not every crack in your render means something has gone seriously wrong, but it can be hard to tell the difference between a cosmetic issue and a sign of genuine render failure. Here’s how to tell them apart, and what to do about each.
What Counts as Normal Cracking?
Fine, hairline cracks that follow no particular pattern are extremely common, especially in traditional sand and cement render, and are usually caused by natural shrinkage as the render cures or by minor building movement. These cracks rarely let in significant amounts of water and can often be monitored or filled as part...
