Many homeowners believe treating a fence is a simple task, yet small mistakes can lead to peeling, rot and uneven finishes. Even the sturdiest fencing can become vulnerable if it is not properly prepared and maintained.
With the right approach, your garden timber can stay strong, attractive and protected against the elements for many years. To help homeowners get it right, Jack Reading from exterior paint specialists Emperor Paint has shared the most common mistakes people make when treating their fences.
Speaking this time last year, Jack said: “I would urge Brits to act now to protect any untreated fences with a waterproofer. This will help to prevent your fences from being damaged by the wetter autumn and winter weather.”
What to avoid when treating a fence
Failing to remove dirt and debris
Skipping this vital preparation stage can prevent your fence treatment from properly penetrating the wood, reducing its effectiveness. Garden timber regularly collects dirt, moss and organic matter, all of which must be removed before any treatment is applied.

Heavy soiling can be tackled with a pressure washer; for less grimy fencing, warm soapy water and a soft brush will suffice. On older wood, light sanding with 180-grit sandpaper helps to expose the timber’s natural surface.
Skipping the application of fungicidal cleaner
Mould, algae and mildew can take hold on your fence if left untreated, creating dark patches beneath your waterproofer. Using a fungicidal cleaner guarantees any organic growth is eliminated prior to applying your treatment, particularly on timber that has been exposed to the elements for more than a year.
Apply this with a brush, roller or sprayer, and allow it to dry for a minimum of two hours.
Failing to protect the surrounding areas
Overspray or drips can damage patios, plants and garden furniture. Cover nearby surfaces by laying down dust sheets and applying masking tape to edges such as fence posts.
Every timber surface differs slightly, and certain treatments may alter the wood’s appearance more than expected. Testing a small, inconspicuous area beforehand ensures you get the finish you are looking for.
Applying treatment when the timber is wet or rain is forecast
Wood must be completely dry before any treatment is applied, as moisture within the timber or approaching rainfall can impede absorption and undermine the finish. Always check the moisture levels of your fence and the local weather forecast before getting started.
Using a small brush can make achieving even coverage difficult and slow the whole process down. For the best results, opt for a 3″ brush, medium-pile roller or hand-pump sprayer when applying waterproofer.
Overapplying or underapplying
Inadequate treatment renders timber susceptible to damage, while over-application can lead to an irregular finish. For example, Emperor Exterior Wood Waterproofer requires just a single coat at 5m2 per litre for maximum protection.
Neglecting long-term maintenance
Many wood treatments demand re-application every two to three years. Purchasing a premium-quality waterproofer ensures protection for at least 25 years without maintenance, reducing long-term hassle.
