Timber Cladding Maintenance Guide
Keep your timber cladding looking its best with our simple maintenance guide.
General Maintenance
Here are four essential maintenance tips to help protect your cladding from the elements, preserve its appearance, and extend its lifespan.
Osmo Protective Finishes
We recommend Osmo products to all our customers, as they are specially formulated to protect timber while enhancing its natural beauty. Unlike standard coatings, Osmo penetrates the surface rather than sitting on top, allowing the wood to breathe and reducing the risk of cracking or peeling. It’s easy to apply, maintain, and re-coat over time, making it a reliable choice for both softwood and hardwood cladding.
How to Apply:
1. Clean the cladding thoroughly and ensure it is dry.
2. Apply the UV-protective finish evenly using a brush or roller, ensuring full coverage.
3. Let the finish dry completely before exposure to sunlight.
Reapply the UV treatment every 6-12 months, depending on the exposure of the cladding to direct sunlight.
Seasonal Maintenance
Seasonal inspections are key to spotting minor issues before they become bigger problems. Early maintenance helps extend the life of your cladding and keeps it looking its best year-round.
What to look out for:
- Cracks and splits: These can allow moisture to seep in, potentially causing damage to the underlying structure. If you notice any, fill them with a suitable wood filler or sealant.
- Loose or damaged panels: Check for loose cladding boards, nails, or fasteners and secure or replace them as needed.
- Mould and mildew growth: Treat any areas affected by mould or mildew with a wood-safe cleaner or fungicide to prevent the issue from spreading.
Cladding FAQ's
How long does timber cladding last?
With proper care and maintenance, timber cladding can last anywhere from 15 to 30 years+, depending on the type of wood used and the exposure to weather conditions.
Do I need to treat timber cladding?
While it is optional, treating timber cladding with a preservative helps to protect it from weathering, UV damage, rot, and insects. Regular maintenance treatments are recommended to prolong the wood's lifespan.
Will timber cladding turn grey over time?
Yes – all timber naturally weathers to a silvery-grey tone when exposed to UV light and moisture. If you want to maintain the original colour, use a UV-protective oil or stain regularly.
Can I pressure wash timber cladding?
It’s best to avoid high-pressure washing, as it can damage the wood surface and force water into the grain. Instead, use a soft brush or low-pressure hose with a mild wood cleaner.
