Keeping render safe from the weather

One of the biggest obstacles in our industry is the unpredictable UK weather. This is something everyone knows about. It can influence a property’s render in all kinds of ways. We want to explore how you can safeguard it from the weather and what you need to be aware of. Then, if you want help from the top plasterers in Sheffield, you can speak to us.

The impact of weather

Cement reacts with water because of the silicates in it. However, the reaction can change depending on the temperature. Thus, you need to understand what you can do to stop issues developing with the render. Most render products need applying between temperatures of 5ºC and 30ºC. Applying over or under these temperatures risks unintentional harm as the render sets. Cracking is an example.

Render is also a porous, natural material. So, it is vulnerable to damage from UV exposure, temperature extremes, moisture, and other environmental factors. Saying this, there are things you can do to protect your render and keep it looking great. This will be the case even in changing or harsh weather conditions.

Humidity and moisture

Plasterers SheffieldLet’s talk about how the weather affects render, starting with humidity and moisture. Humid or damp conditions can foster the growth of algae, mildew, and mould on the surface. This happens a lot in tropical or warm climates. To halt the problems, you must promptly dry the surface. It will ensure you don’t trap moisture.

If algae, mildew, or mould develop on the render thanks to moisture, you need to clean it using water and bleach. Or, you can use a commercial mildew/mould remover. Thoroughly rinse the area once you’re done and let it dry properly.

For continuing protection, utilise a fungicidal render sealant. It will help stop mildew, mould, and fungi growth. Re-applying the sealant is something you should do periodically. This is especially important after cleaning mildew or mould from the render. Contact us if you need help from the greatest plasterers Sheffield has to offer.

Cold and freezing temperatures

In colder climates, the constant freezing and thawing of render can result in it crumbling or cracking. To stay safe from such damage, you could install insulation behind it. Or, you can apply a weather-resistant sealant. Such a sealant works to stabilise the render’s temperature. It also minimises the expansion and contraction that causes cracks.

If cracks do show up because of the freeze/thaw cycle, you must repair them ASAP. Use a render patching compound to do so. Apply the patch once temperatures rise above freezing. The material won’t crack this way.

Sun and heat

Lastly, prolonged sun exposure can cause the chalking, fading, and faster deterioration of render. To protect against sun damage, apply a UV-blocking render sealant. It is best to use an acrylic or silicone one especially for external render. Re-applying the sealant every few years will help keep the protection up.

Furthermore, think about restricting sunlight exposure. Do so by installing trellises, overhangs, or similar shading structures over your render. Light-colour renders that contain titanium dioxide or other UV-resistant substances are a great choice. In addition, renders possessing more solid, smoother exteriors are less vulnerable to UV degradation. If you have render that is already suffering from sun damage, cleaning and re-sealing can aid in restoring the appearance. You can also defend it from further harm.
