A brief overview of LifeWood CCA, NatureWood ACQ and MicroPro Sienna timber treatments.

CCA (Copper Chrome Arsenate) has been used as a wood preservative since the 1930’s and has been used in a myriad of applications including landscaping, utility poles and decks and wharfs. It is suitable all Hazard Class situations (the "H" level marked on the timber) although in recent years its use has been restricted so it may not be used in childrens playgrounds, deck boards, hand railings and picnic tables.

ACQ (Alkaline Copper Quaternary) is one of a number of later generation preservative formulations and relies on copper as a fungicide and a co-biocide being an organic quaternary compound. ACQ can be used in H1 to H5 Hazard Classes and can be used in all situations including those restricted for CCA.

MicroPro Sienna is the most exciting development in outdoor timber products for many years.You can now buy coloured preservative treated timber in an attractive hardwood colour that will complement your landscaping project. MicroPro Sienna uses the latest generation timber preservative and "micronized" pigments that are pressure treated into the wood to give longer lasting colour that is not just "skin deep" Micropro Sienna has received many environmental certifications and is Greenguard Gold certified for low chemical emissions.
