We have compiled the below information in relation to the care and maintenance of your garden timber products – we hope you find this guide helpful
First of all congratulations on the purchase of your garden timber product! We would love for you to be able to enjoy your garden timber for many years to come. Below you will find useful information and links on how to care for your product in the years to come.
It is important to note that timber is a natural product and will respond as such to environmental changes. Timber is highly susceptible to relative humidity and weather conditions and will undergo expansion and contraction over time.
Useful Links for Understanding Timber Products
Below you will see 2 x links with images to what to expect from your timber product in the years to come
If you have read all the below information and are still unsure then please feel free to contact us at firstname.lastname@example.org If you already have a timber product then please be sure to include images within your email so that we can advise fully.
Different types of Timber:
Most timber used for garden product is kiln dried (except in the case of certain hard wood furniture type products). In general it is not seasoned. BOTH processes result in resin coming to the surface, splits and cracks as wood will always respond to its environment regardless of how “Free Moisture” has been removed.
Presure Treated Timber
It should be borne in mind that Pressure Treated (using any branded product ie Tanalize, Tanalith, Wolmanit etc) whilst offering a very long life span to timber garden products actually exacerbates the effect of the natural environment on a timber product hence splits and cracks in pressure treated products are VERY common, they can be deep and can appear quickly however again they do not affect the structural integrity of a product and will often open and close again with the changing of the seasons.
Another common feature of pressure treated timber is that as the wood slowly dries, and consequently contracts there is frequently a residue that appears on the surface of the wood. This residue can be mistaken for mould as it is green / blue in colour but it is not mould and is not a fault. The residue can be wiped off, dusted off with a stiff brush or simply left as it will weather away over time.
Both Pressure Treated and Factory Dipped products can appear to be unevenly treated owing to the uneven capacity of wood across its surface to absorb treatment. Please be assured that both processes involve completely immersing the wood in wood treatment hence it is not possible that the wood may be unevenly treated - it is simply how the wood actually appears after treating.
More Timber Information
All Timber will expand and contract according to its environment. As a result of this expansion and contraction – it is very common to see resin rising to the surface of the wood (resin is present in all woods but particularly so in soft wood species including pine, spruce and certain cedars), splits and cracks developing in the wood. These can sometimes be significant however they do not affect the integrity of the product and will usually close over time (but not always). Splits are extremely common during the spring and summer as the wood begins to dry out and consequently to contract on its outer surfaces before the core of the wood dries hence the outer surfaces contract over a still expanded core of the wood. The result of this is that splits and cracks appear along the grain of the wood. These splits are not a fault, and as a result are not covered by any warranty, and do not affect the structural integrity of a product that has been correctly assembled but are simply a part of the how timber products respond to their environment.
All timber will feature knots. This is part of the appeal of timber product and is in no way a fault.
Timber and the Effects of Hot Weather Conditions
During the summer of 2018 when we experienced an unprecedented heat wave, this unusually hot spell wreaked havoc within the timber industry. Timber product reacted to this environmental change and instances of shrinkage and warping were at an all time high. The advice within the timber industry was to water the timber to help with moisture content and to wait for the higher temperatures to pass so that the wood could be allowed time to settle back. By the Autumn of 2018 instances of shrinkage and warping of timber had subsided and this excessive effect within the industry returned back to a normal level.
Please Note: warping, splits, cracks and gaps that appear in timber are all part of the regularisation of timber and are not covered by any warranty / guarantee as this is not a fault. These will not affect structural integrity, they will not have a detrimental affect on your product and will usually by itself resolve with the changing of the seasons. If you require remedial action then the best thing to do is to water your garden timber to help restore some of its moisture content.
