Five top tips on weatherproofing your cladding this winter

As winter approaches, many homeowners are busy thinking about Christmas, winter holidays and other seasonal activities. Yet, the change in season and the unpredictability of the weather can cause havoc on external wooden surfaces – snow, ice and rain can cause all kinds of cosmetic damage.

Steve Grimwood, Managing Director of Osmo UK, reveals his five top tips for weatherproofing your external cladding this winter.

1. Preparation

Before you consider applying a wood finish, it’s essential to ensure that your cladding is fit for purpose. Fix any loose boards and make sure that there are no gaps or areas needing urgent maintenance and repair. By ensuring that the cladding is appropriately prepared, you can minimise the risk of structural damage in the event of a storm.

2. Invest in a good base

I would recommend using a base coat before applying any protective and cosmetic finishes to the cladding. A good base coat will penetrate the surface of the wood, which not only provides extra protection but will also help to prevent rot, stain and other damage. Base coats can be easily applied with a roller or flat brush, to ensure even distribution and coverage.

3. Make sure it’s water repellent

When choosing an appropriate finish, the first thing you should do is look at what that product can offer. You are going to want to look for a finish that is water-resistant – this will help to protect against wintery weather conditions, including heavy rainfall. Many finishes available on the market now contain active ingredients – these work to slow the growth of mildew, algae and fungi. This will ensure professional results that do not crack, flake, peel or blister.

4. UV protection

It may be cold outside, but winter UV rays can still cause a considerable amount of damage on external wooden surfaces. As all wooden surfaces will inevitably start to grey over time, it’s important to invest in a finish that aims to slow the process down. Investing in a finish that provides UV protection will help to maintain the appearance of the wooden cladding for many years to come.

5. Care and maintenance

Ensuring the longevity of your cladding should be a regular part of your care and maintenance routine. Frequent cleaning of external surfaces will moisturise the wood’s surface, helping to maintain its freshness whilst removing any debris or dirt.
