Numerous property owners believe applying fence treatment is straightforward, but minor errors can result in peeling, decay and patchy finishes. Even the most robust fencing can become susceptible if it isn't correctly prepared and treated.
With the proper method, your garden timber can remain durable, attractive and shielded from the elements for years to come. To assist homeowners in achieving success, Jack Reading from exterior paint specialists Emperor Paint has revealed the most frequent errors made when treating fences.
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."
Neglecting to clear away grime
Overlooking this crucial preparation phase can stop your fence treatment from adequately penetrating the timber, diminishing its performance. Garden timber frequently accumulates dirt, moss and organic matter, which must be eliminated before applying any treatment.
Substantial dirt can be cleared using a pressure washer; for less dirty fencing, warm soapy water and a gentle brush will be adequate. On aged wood, light sanding with 180-grit sandpaper assists in revealing the timber's original surface.
Omitting fungicidal cleaner application
Mould, algae and mildew can linger on your fence if not treated, risking dark patches beneath your waterproofer. Utilising a fungicidal cleaner ensures any organic growth is eradicated before applying your treatment, especially on timber that's been exposed to the elements for over a year. Apply this using a brush, roller or sprayer, and let it dry for at least two hours.
Neglecting to safeguard the surrounding areas
Overspray or drips can harm patios, plants and garden furniture. Shield nearby surfaces by laying down dust sheets and using masking tape on edges like fence posts.
Bypassing a test area
Every timber surface is slightly different, and some treatments may change the wood's appearance more than anticipated. Testing a small, discreet area first ensures you achieve the desired finish.
Applying treatment when the timber is damp or rain is imminent
Wood must be entirely dry before applying any treatment, as moisture in the timber or incoming rain can hinder absorption and compromise the finish. Always check the moisture content of your fence and the local weather forecast before starting.
Using the wrong tools
Using a small brush can make even coverage challenging and slow the process. For optimal results, use a 3" brush, medium-pile roller or hand-pump sprayer for applying waterproofer.
Overapplying or underapplying
Insufficient treatment leaves timber vulnerable, while excessive application can result in an uneven finish. For instance, Emperor Exterior Wood Waterproofer only necessitates a single coat at 5m2 per litre for optimal protection.
Overlooking long-term upkeep
Numerous wood treatments require re-application every two to three years. Investing in a top-quality waterproofer guarantees protection for a minimum of 25 years without maintenance, minimising long-term inconvenience.
