Building a Deck – Things to Check if Using Softwood Species

 


Article by: Malcolm Kay

Whilst hardwood is generally the preferred lumber species for exterior decking due to its hardness, resistance to wear and attractive colour, , Managing the Hobby Greenhouse softwood species are commonly used, particularly where cost is an important factor. But the drawback of most softwoods is that they are not naturally durable so are unsuitable for use in areas fully exposed to the weather , Wrought Iron Garden Benches unless the wood , Manage Algae is properly treated with a recognized wood , The Garden Beckons preservative or completely sealed with an impervious surface coating. So when selecting a softwood species, one of the most important considerations is that these species used should be either a recognised naturally durable species such as Western Red Cedar, some species of cypress, larch or pine, or that it has been treated with an appropriate and good quality preservative.

For more than 70 years, the most commonly accepted wood , Forest Tent Caterpillars preservative treatment chemical has been CCA (copper chrome arsenic), which gained popularity due to its effectiveness and relatively low cost. (CCA treated lumber can normally be distinguished by the greenish tone it imparts to the wood). However in recent years, many national organisations and authorities have announced either bans or restrictions on the use of lumber treated with CCA. For example, in Australia from March 2006, CCA treated timber , Choosing the Right Sprinkler System will no longer be permitted for use as handrails, decking boards, picnic tables, or children's playground equipment in new installations. And in Japan, CCA treated lumber is generally not permitted any longer for public use in major cities for municipal projects.

Although there is apparently no firm scientific proof to support the contention that CCA timber , Garden Delights For Midsummer is harmful to health provided it is handled correctly, such cautions or bans have been instituted as a precautionary measure. Nevertheless it is always best to err on the side of safety, , Spring Wild Flowers so it is recommended that when working with CCA treated lumber, to apply protective clothing including goggles, face mask and gloves. CCA treated lumber also should never be burnt in an open fire , Sampler of Rare Fruits for Fun or Profit but must be disposed of according to local regulations. , Turn Your Patio Into A Voluminous Vegetable Garden
