Key Take Aways

  • Choose coatings that combine aesthetics with performance – colour variety matters, but the best products also offer durability, UV resistance, and long-lasting finish.

  • Silicone‑enhanced products offer superior weather resistance, effectively repelling rain while maintaining surface integrity and opacity.

  • Breathability is essential – microporous coatings allow internal moisture to escape, preventing damp and mould build‑up within walls.

  • Quick‑drying formulations minimise weather‑related application issues, reducing the risk of cracking or failed cures in fluctuating London conditions.

  • Experienced applicators are key – skilled professionals ensure proper surface prep, application technique, and guarantee fulfilment.

  • Look for long guarantees (up to 25 years) – reputable firms like All Weather Coating offer extended warranties backed by testing and strong customer reviews.

Deciding to repaint your home’s exterior is the easy part. Deciding what kind of materials to use to repaint your home is far trickier.

Given the amount of time and money involved, you are going to want to be certain that you are equipped with the best materials possible with which to complete the job. The sheer volume of information online can be overwhelming and sifting through it all to find a kernel of truth is time-consuming.

To shorten this process and to help you make the right decision about your home’s exterior, we have put together this post that illuminates exactly the kind of things you should be looking for in an exterior wall coating product.

Appearance

Covering the entirety of your home’s exterior in a product that isn’t aesthetically pleasing is the worst thing you could do. Practical features like durability are of course important but they are redundant if the appearance of the wall coatings isn’t up to scratch. Available in a broad range of colours, our wall coatings are designed to fit every exterior and you are sure to find one that is perfect for your home. Regardless of the tone you pick, you can be certain that you will be delighted with the end result.

Weather resistance

Weather resistance is one of the most important qualities to look for in an exterior wall coating. Being able to fend off everything the weather has to throw at your home is integral to maintaining your home long-term. Given the temperamental nature of the British weather, your exterior wall coatings should possess the ability to properly protect your home in a variety of different conditions. Our weatherproof coatings for example, are imbued with silicone, which acts as a water repellent – making your home’s exterior impervious to rain.

Breathability

Breathability is both an underrated and overlooked quality in wall coatings. While it seemingly goes against conventional thinking to make a product that is meant to keep the elements out breathable, it is actually essential. An impassable covering will prevent water vapour that accumulates within your home from escaping – leading to damp problems. A breathable wall coating then, not only keeps water out of your home, it prevents water from causing issues within the home too.

Quick-drying

The application process needs to be conducted in precisely the right conditions if your new home exterior is to stand the test of time. The obvious culprits – rain, wind and snow are all capable of derailing the application process but subtle changes in temperature can be equally culpable. If the temperature is too low, too much moisture will be retained. Conversely, if the temperature is too high, the wall coating will dry too quickly – increasing the likelihood of cracks developing at a later stage. With a quick-drying product, the risks of weather impeding its progress are dramatically reduced.

You also need an experienced and knowledgeable team carrying out the application process

Equally as important as the exterior wall coating product itself, are the people applying it. At All Weather Coating, we have an abundance of experience applying wall coatings to buildings throughout London and the Home Counties.

Over the years, we have perfected our application process and in just a matter of days, you can rejuvenate your home’s appearance and keep it protected for decades.
