See Product Data Sheet for full details on all products. Directions Prior to starting, test Jac Jay cleaning products on the surrounding surfaces of the area to be cleaned (e.g. paint work, aluminium, tiles, etc.) to check for colourfastness and reactions of these surfaces. Do not use on unprotected lead. You will obtain better results by cleaning timber when it is cool to the touch and out of direct sunlight.  Never let products dry on the surface. Cleaning by section is recommended, i.e. along the length of each piece of timber fully, rather than across various sections simultaneously. Prior to starting, hose down all areas that do not require cleaning and keep wet during the cleaning process. Apply Jac Jay Timber Revitaliser by spray bottle, applying to the area that is to be cleaned only. Leave Jac Jay Timber Revitaliser on for 3–5 minutes to soak in. Re-apply Jac Jay Timber Revitaliser by spray bottle, ensuring the timber is well wet with the product prior to scrubbing. Scrub firmly taking care not to damage the timber.  Always scrub along the grain and never across.  Scrubbing brush should be of a medium stiffness as you do not want to scratch or damage the timber. To remove all residue, thoroughly hose down with light pressure using fresh clean water.  Do not water blast as this will strip low density parts of your timber out and lapping marks will show when recoated.  Hose down all surrounding areas which have come in contact with the cleaning products. Leave timber to stand for 3 minutes to allow surface water to run off before proceeding with the following stage. Because of the natural tannins which occur in Western Red Cedar, Redwood, Kwila and some other timbers, they will appear darkened at this stage of the cleaning process.  On some timbers that do not darken, Jac Jay Oxalic Acid will not be required or will have a limited effect. After timber has been left to stand for 3 minutes, and is still damp, apply Jac Jay Oxalic Acid to the area being cleaned.  Apply wet on wet with a soft brush, gently working on to the timber surface. Leave Jac Jay Oxalic Acid on the timber surface for 10-20 minutes and then thoroughly hose off with clean fresh water.  Hose down all areas that have come in contact with the cleaning product. Take care to apply cleaners to the timber only.  When washing down, use generous quantities of water to dilute cleaners and wash all areas that the cleaners have come in contact with. Leave for 5–6 days to dry in ideal drying conditions, longer may be required. Dispose of all materials safely.  Do not dispose any material down stormwater systems.  Contact your local council for correct disposal methods. When doing any work always follow good trade, health and safety practices. Follow all good coating practices. Recoating See Recoating of Previously Coated Surfaces section of the Product and Application Guide. Please Note  When coating timber previously coated with migrating oils, the last application should have been a minimum of 18 months prior to the restoration process.  This is to allow a reasonable time period for the oils to leach out from the timber.  When recoating timber that has previously been coated with migrating oils there is a small risk that, if there is still a high oil content in the timber, it may lift the new coating.   Every care is taken to ensure that the information provided in this data sheet is accurate.  Jac Jay Limited is unable to guarantee results as it has no control over the conditions under which products are applied, the substrate or the application.  The customer has to determine the suitability of the delivered products or information for its intended purpose.
