How to Treat Your Fence

28-April-2016
Whether you’ve put in a new fence that needs some protection or you’re looking to re-treat a fence that is looking a little worse for wear following the winter months, the longer, brighter days we’re getting means now is an excellent time to apply a protective treatment to your garden fencing. There are a number of stains and treatments available that can help prolong the life of your fence panels and ensure they last as long as possible. If you’re going to spend the time and care to maintain your fencing, you’re going to want it to look as good as possible too. As well as providing a level of waterproofing to stop wet rot and decay, a number of the protective treatments we have include a UV filter to prevent the colour from fading.

Cleaning and Preparation

Cleaning your fence will make sure the treatment you apply works properly and is as effective as possible. As they’re constantly exposed to the elements, fence panels in shady areas provide an excellent environment for mould and moss to grow in and it is important to get rid of this completely before you start applying any paint, stain or treatment to your fencing.

    1. Before you begin, cover any delicate plants or bushes with upturned buckets or sheets of tarpaulin to stop them being damaged.
    2. With the pressure sprayer on a low setting, or using a hose with a spray gun or misting nozzle on the end of it, gently rinse away any loose debris from your fencing. Be careful not to concentrate the water in the same area for too long.
    3. Any areas with marks, mould or moss left on will need to be scrubbed by hand. Using a stiff bristled brush, scrub the fence panels to loosen tougher dirt and unwanted spores.
    4. Lightly sand the surface of your fence to help the treatment work effectively. This is especially important for new fences as well as fences that have been treated or stained previously.
    5. Rinse the fencing again to wash away anything that may have been loosened in steps 3 and 4.
    6. Uncover any plants, shrubs or bushes you covered up to protect in step 1.
When you have finished, you’ll need to wait for your fence to be totally dry before moving on to the next step…

Treating Your Fence

Applying your fence treatment

When your fence panels are clean and dry, you are ready to treat your fencing. It is best to choose a clear, dry day to treat your fence, as it will need to dry thoroughly once it has been treated. Wind can pick up small debris and blow it into wet fence panels. If you want to use a pressure sprayer to treat your fencing, be aware that wind can carry the particles a reasonable distance. Making sure there is as little wind as possible for either type of application is a great idea and you may also want to speak to your neighbours if you’re looking to use a pressure sprayer!
  1. Cover any plants shrubs or bushes that cannot be moved away from your fence. This is especially important if you are using a pressure sprayer to treat your panels. This can again be done with upturned buckets or tarpaulin.
  2. Lay a sheet on the ground below your fence to catch any drips and protect the surface below. If you’re using a pressure sprayer you may want to cover up a larger area as it will have a bigger range.
  3. Make sure that the treatment or stain you have chosen is suitable for use with your application method. Some treatments will only be suitable for application with a brush and others will only be suitable for application with a pressure sprayer and others can be used either way so it is important that you check before you start.
  4. Follow the instructions on the back of your treatment to apply it. These will vary for different types of treatment and they may not work properly if these are not followed.

Treating your fence regularly can help extend its life and keep it looking as good as possible all year round. How frequently you need to do this will depend on the type of treatment applied. For a low maintenance option, Ronseal’s 5 Year Fence Life should only need topping up once every 5 years. If you’d like to get the job done quickly, Ronseal’s One Coat Fence Life can dry in as little as 1 – 2 hours, leaving you more time to enjoy the sunshine. There are a range of colours available, so if you’re looking to stand out or blend in we should have just the thing.
