Know Your Timber

Guide To Popular Timbers & Their Properties

Timber is affected by moisture, UV light and mould development over its surface and all these elements are known to deteriorate its life. Hence, an effective timber protection solution will defend the timber from these well-known elements. As a rule of thumb in an exterior DIY project involving timber the denser the timber the more weather resistant it is considered to be.

We live around many popular softwoods and hardwoods and it is advantageous to know their properties before we decide to treat them with stain or varnish. Natural characteristics of timber will impact the final finish and appearance especially if on staining or varnishing them. Some of the popular timbers we live around may have resins, tannin or oil in it which may also affect the aesthetics of your timber project.

 It is recommended to clean timber with Mineral Turps if you are using an oil-based product or Methylated spirits if you are using water-based product prior to staining. Allow these solvents to dry properly after you wipe off any excess with a clean rag.

Softwoods Vs Hardwoods

About 80% of the timber we use and see around us in our houses are softwoods. Most hardwoods are typically expensive as compared to softwoods.

Hardwoods are highly durable and typically more durable and denser as compared to softwoods. However, it may be noted that not all hardwoods are harder and denser than softwoods.

 Because of the open pores softwoods are easier to treat with stain as they absorb them with ease as compared to hardwoods. Hardwoods are typically used in high end furniture, decking and structural applications where long-lasting timber is required. Softwoods are used in construction of wide range of applications such as doors, windows, furniture etc. Soft timbers are also generally of lighter natural colours as compared to hardwoods.
