How to Repair Cracked Render

Cracked Render Repair Services

Starting out as nothing more than a tiny fracture on your home’s exterior, cracked render may seem like a non-issue, but left unattended, it can easily spiral into a major structural issue (not to mention an aesthetic one). Damp can very easily become part of the furniture of your home, making it essential to address any cracks and crevices the instant they appear. The good news is that repairs can be swift and painless – close to two decades of restoring render in UK homes have taught us that.

If you have noticed a crack in your home’s external render, here’s how you can go about repairing it and ensuring that it never becomes an issue again.

What causes render to crack?

Low quality and ill-protected render will always be exposed in testing weather conditions. More often than not though, the way in which the render is applied is just as important as its quality, which serves to highlight the importance of hiring a cracked render repair service rather than taking matters into your own hands.

Applied in the wrong weather conditions, render will fail to last. If the temperature is too low (below 5°C), the curing process will stagnate, causing moisture to be trapped within the render. Too high, and the render will dry out too quickly, resulting in the formation of cracks.

Any form of precipitation is no ally of rendering either – rain, snow and sleet will adversely affect the moisture levels in the render, culminating in shrinkage cracks.

Why is it so important to repair render?

Cracked render is a route through which water can infiltrate your home. Water ingress will lead to perpetual damp in your home – rendering your home cold and damp – the opposite of what a home should be. Over time, continued damp will cause your home to deteriorate drastically; wallpaper will loosen and paints and plasters will decay.

Alongside the practical ramifications of living in a structurally unsound home, there is an array of associated health risks. Bacteria and dust mites flourish in damp conditions, allowing respiratory illnesses to run riot.

How to repair cracked render?

Firstly, we ensure that all areas not being treated are covered – paths and gardens with dust sheets and windows and doors with paper and tape. Small cracks are filled with epoxy resin while larger cracks are treated with special bonding primers before being filled with a sand and cement mixture.

After the render has been given ample time to dry and solidify – and a comprehensive cleaning process has been completed – it is time for the application of a silicon-based weatherproof wall coating. Mixed with an appropriately coloured final coating, the waterproof wall coating is applied using a pump that carefully regulates the ratio of coating to air, resulting in a perfect finish that will protect your home from damage for 25 years.
