![]() We recommend using solvent-based wood preservers on treated wood as this will benefit all types of timber, regardless of the treatment method that was previously used. It is advisable to apply preserver to previously treated timber, as this will improve your timbers protection and help prevent cracking. Applying preserver to wet wood is a futile exercise as both oil-based and solvent-based preservers - due to their oil content - will be rejected, whilst water-based preservers will not be absorbed by the already saturated wood, resulting in unprotected wood and wasted product.ĭo you need to apply a wood preserver if using treated wood? We would not recommend using it any later than this as exterior wood becomes progressively wetter during the autumn and winter months. If you find yourself running out of summer months do not panic at a stretch wood preserver could be applied up till October. The summer months are therefore an ideal time to get outside and commit some time to exterior wood protection.īut as we well know, DIY and restoration does not always adhere to carefully plotted timetables. Wood preservers are best absorbed and most easily accepted when wood is warm and dry. What is the best time of year to apply wood preservers? However, in certain circumstances - such as when treating wood in poorly ventilated areas - water-based products should be used as they are non-toxic and carry minimal odours.īarrettine Wood Protective Treatment (5L)īarrettine Premier Universal Preserver (5L)Įverbuild Lumberjack Triple Action Wood Treatment (5L)īarrettine Log Cabin & Complete Decking Treatment (5L) This is because solvent-based preservers are absorbed deeper into the wood, resulting in stronger and longer lasting protection. The answer to this question depends on a number of factors, but generally the best wood preservers are solvent-based, such as Barrettine’s Premier Wood Preserver. When applying preservers to larger surfaces such as fences, we recommend using a paint sprayer as this will save you a considerable amount of time. You should use a brush to apply your wood preserver to smaller or more intricate pieces of timber. It is important to note that all types of wood preserver are best applied to raw, bare wood, be it freshly sawn or sanded down. All these preservers can be applied via two methods with a suitable brush or an airless paint sprayer. There are three types of wood preservers: water-based wood preservers, oil-based wood preservers, and solvent-based wood preservers. When applied, preservers stabilise the wood’s moisture levels and protect it from decay by acting as a protective barrier, repelling water and preventing invasive organisms from entering. As little as one application per year can extend the lifespan of your wood dramatically, meaning you can rest easy no matter what nature throws your way. Wood preservers offer the most efficient and cost effective means of protecting against all the previously mentioned processes. As such, it is absolutely vital to invest in some form of exterior wood protection, lest wood start decaying before your eyes. Wood boring insects, such as the dreaded woodworm, also pose a risk to unprotected timber and can rapidly decimate exterior wood. Prolonged and intense exposure to the sun’s UV rays also damages wood fibres and can cause planks, beams, and frames to warp and crack. Water, most commonly in the form of rain, poses a frequent and potentially damaging threat to wood as increased moisture can cause wood to swell, mould, and eventually rot, whilst unprotected wood left in dark damp conditions will turn an unattractive green due to the growth of algae. ![]() The frustratingly changeable nature of Britain’s weather ensures that exterior wood is at risk of suffering from a number of damaging processes over short time periods. For wood that is left exposed to the elements, such as garden furniture, sheds, and fences the process of degradation will occur much more rapidly than wood that is under shelter or indoors. ![]() Applying wood preservers is a fundamental step you can take that will protect exterior wood from damage, degradation, and disintegration.Īs an organic material, wood is naturally prone to degrading over time.
