• Some preservative may migrate from thetreated wood into soil/water or may dislodgefrom the treated wood surface upon contactwith skin.Wash exposed skin areasthoroughly.
• The red colour is a pigment not apreservative.This is fixed to the timber anddoes not wash off. Some surface deposits ofpigment may rub off.This is easily washed off.
• All sawdust and construction debris should becleaned up and disposed of after construction.
• Wash work clothes separately from otherhousehold clothing before re-use.
• Preserved wood should not be used where itmay come into direct contact or indirectcontact with drinking water, except for usesinvolving incidental contact such as fresh waterdocks and bridges.
• Do not use preserved wood undercircumstances where the preservative maybecome a component of food, animal feed,or beehives.
• Do not use preserved wood for mulch.
• Only preserved wood that is visibly clean andfree of surface residue should be used.
• Use fixings, hardware or any metal productsas recommended by their manufacturer.
• If wood is to be used in an interior applicationand becomes wet during construction, itshould be allowed to dry before beingcovered or enclosed.
• Disposal Recommendations: Preserved woodmay be disposed of in landfills or burned incommercial or industrial incinerators orboilers in accordance with National andRegional regulations.
• If you want to apply a finish to yourpreservative treated wood, we recommend useof oil-based penetrating finishes that are
transparent or semi-transparent. Some clearwater repellents and semi-transparent stains can be applied to treated wood soon afterconstruction.We do not recommend usingpaint or other film-forming finishes becauselong term maintenance of these finishes canbe problematic.Whatever finish you use,always check the label of the finishing product and follow the manufacturer’sinstructions.Apply the finishing product to asmall exposed test area of your projectbefore finishing the entire project to ensure it provides the intended result beforeproceeding.
• Use fixings and other hardware which are incompliance with building regulations for theintended use.
• Mould growth can and does occur on thesurface of many products, including treated oruntreated wood, during prolonged surfaceexposure to excessive moisture conditions.To remove mould from treated wood surfaces,wood should be allowed to dry.Typically, mildsoap and water can be used to removesurface mould.
• Cross cut battens ends: It is recommended thatcut batten ends at the verge should betreated with a suitable preservative approvedfor this purpose.The most practical and safeway of meeting this is to rotate the battenalong its length so that the cut end is insidethe roof and the fully treated end is at theverge.This negates the need to carry up andpaint /dip batten with a preservative whilston the roof. Cut batten ends within the roofdo not require further treatment
• If cutting cannot be avoided, then precautionsshould be taken to keep airbourne dustlevels below Occupational ExposureStandards for wood dust. In particular, avoidinhalation of dust when using high speedcross-cut saws or mechanical sanders.
