Directions For Use
TWA CLEARWATER REPELLANT is intended to protect and enhance the beauty of any exterior timber surface. It is suitable for decking, fencing, cladding, furniture, lattice, windows, pergolas and any other similar timber surface. It is the ideal complement for CCA, Tanalith-E, ACQ & LOSP treated timbers.
Many hardwoods particularly when new may be difficult for the TWA CLEARWATER REPELLANT to penetrate, this may cause drying and surface problems. In these cases, it is recommended to allow the timber to season for a period of 3-6 months until satisfactory penetration and drying can occur. An alternative is to apply a diluted solution of TWA CLEARWATER REPELLANT (50:50% Mineral Turps), wipe off any excess after 24 hours, leave for 3-6 months and then apply another full-strength coat of CLEARWATER REPELLANT. Always test brush in a small area or on off-cuts before doing the full area.
Mix thoroughly before use to ensure solids and pigments are evenly distributed. A pigment may be settled and compacted after extended shelf storage. Thinning is not normally required. However, if the product does not readily absorb, (to new dressed timber, hardwoods or during cold weather), thinning with mineral turps may assist penetration. Normally 1 or 2 parts of turps to 10 parts of the product will be sufficient. The total number of coats may need to be adjusted to achieve the desired properties.
New timber should be dry and free from dirt, sawdust etc. Old or weathered timber should be treated with TWA WOODBRITE prior to CLEARWATER REPELLANT for best results. Even new timber that is watermarked and dirty will benefit from treatment with TWA WOODBRITE. (Please ensure that the timber has thoroughly dried after this). In order to work properly, CLEARWATER REPELLANT must penetrate, therefore the timber surface should be reasonably dry before application. A drop of water should absorb readily. If not, the timber is not dry enough and should be left for a few more days. (this step is irrelevant for additional coats.)
TWA CLEARWATER REPELLANT can be applied by brush, roller or dip methods. (Ensure adequate ventilation during use and avoid proximity to heat sources or open flame.) Dipping application may require back brushing for an even appearance. Do not use the product if rain is expected
within 24 hours of application. Work it into the timber grain with only a moderately full brush. To get maximum penetration and benefit DO NOT apply CLEARWATER REPELLANT in direct sunlight or onto a hot surface. Similarly, do not apply in very cold weather (>15oC) or very hot weather – above 25oC. Decant into small containers for use rather than leave the main container open for long periods. Stir occasionally during use. Coverage will depend greatly on the timber type and its condition but will generally be in the range of 4 to 8 square metres per litre. Coverage will improve with second and third coats. The surface will be touch dry after 2 hours, however, leave for 24 hours between coats and before use. If possible with new timber wait for one week before applying additional coats. Clean up with mineral turpentine or paint thinner.
Result of Application
TWA CLEARWATER REPELLANT will enhance the grain and colour and may darken some timbers (eg Western Red Cedar). On treated pine, in particular, the effect will be a warmer golden hue that may darken with exposure.
Recommendations and Re-Application
Two coats at least should be applied to exterior timbers. For best protection and results all surfaces (including the underside of decks), should be coated before joining and after cutting or machining. Obviously this will not be possible in many cases. However where possible give special attention to end grain joints and interfaces.
