Prolonging the life span of a timber building is very easy if you flow a few simple steps
Air flow is one of the most important things a timber building needs. The air needs to be able to circulate around the building to let it dry from any rain fall. A building no matter what treatment you put on to it will rot if it’s not able to dry out.
What kind of treatment do you need?
There are many different oil or water based treatments on the market to choose from to give you the look that you desire. When buying the treatment always look on the labels, particularly the cheaper brands to see if they are microporous. Being microporous is essential, as it allows the wood to breath, otherwise the wood will rot from inside to out.
Water base treatments
With the current trends water base treatments are a popular way to treat your building, because they come in a wide rage of colours, unlike oil base treatments. Also they are not flammable nor do not give off hazardous odours. Paint brushes can also be washed in water with this type of treatment.
Water base treatment need to be applied every year for a minimum of 2-3 years then every other year following that although, if you want to maintain a polished and modern look your building may need to be treated annually.
Knots are coming thought the paint work?
Most timber buildings are made from pine which always has a considerable amount of knots. When timber building manufacturers buy in wood, it comes to them with a moisture content of under 18%. Buying wood with a moisture content below this would cost the timber industry millions and would therefore have an impact on the price of the cost of the buildings making them unaffordable.
Knots leek resin for a few years after the wood has been cut, while it dries out. By choosing to use an oil base treatment knots are less noticeable due to the treatment being more of a wood stain which already shows the knots thought the treatment. Water base treatments, have a opaque finish to them which hides the knots, when the resin leaks knots show themselves as brown marks on the paint having an impact on the finish of the treatment.
Some buildings may never get any problems with this, although if the building is in direct sunlight its more than likely you will. This is quite easily solved by going over the knots with a rag and methylated spirits to wipe away the sap, then just retreat the area. Often people choose to retreat the whole building at the same time due to the water based treatments being quick and easy to apply.
Oil base treatments
If you are looking for a treatment which you have to apply less often, but is also very hard wearing oil base treatments are the way to go. There isn’t such an extensive range of colours as there are with water base treatments because they are more of a wood stain rather than paint. When timber buildings are being positioned against walls and fences it is advisable to treat with oil base treatments, applying two coats giving it the best change of not decaying.
Oil base treatments are harder to apply and harder to “touch up” and brushes will need to be cleaned with white spirit. Retreating a building using an oil base treatment would need to have two good coats in the first year then once very 3 years after.
How long will my building last?
It is impossible to give an exact time frame on how long your timber building will last due to it being manufactured using a natural product, but keeping debris off the roof of your building, keeping up with treatment, oiling hinges and make sure your building has a good air flow around it there is no reason why it shouldn’t last 30 years plus.
