Larch wood is a popular cladding choice as it does not need be treated and can be left to weather naturally. However, the weathered look does not suit all properties and there are different finishes available for larch wood to avoid weathering over time. However, these will need to be maintained to keep them looking good and to avoid damage to the timber.
Unfortunately clear finishes that preserve the exact colour of the timber are an impractical choice. UV rays will quickly damage any clear coatings meaning that at best you will be patching up your work every 18 months or so. Without any pigment in the finish it will soon start to crack and flake.
This means that if you wish to maintain the natural warm hues of larch wood then you need to choose a finish with a pigment in that will emphasise the colours. You may want to wait until you have the wood to see exactly what would work best with the wood that you have before purchasing enough product to cover all the cladding.
There are many pigmented finishes on the market, so choose one that is suitable for larch and is guaranteed to last a long time. Having to apply more coats regularly is a big commitment and once you have coated the wood it is important that it is maintained to keep it looking good.
For a more traditional property or a barn conversion you could consider painting the cladding black. This is traditionally a popular choice, but would not suit a modern property. Again, there are a lot of different products on the market, so do your research and find one that is suitable for larch wood and will provide all the necessary protection with a long life span.
White is another popular choice for timber cladding. It is popular for cladding red brick residential properties to break up the harshness of the brick work.
For commercial or public projects that involve larch wood cladding you may be required to treat the timber with a fire retardant. There are a number of different ones available. Some need to be applied in an industrial setting and some take a while to fully protect the wood after it has been treated. The end finish of the wood will depend on the treatment you opt for. Look out for whether or not the product will react with fixtures and fittings and react to other coatings and finishes and whether or not you can still leave the wood unfinished.
Larch wood cladding is perfect if you want to have a natural look, but is also very adaptable if you want to apply a different finish to the cladding.
