Wherever possible dip timber in fluid for at least 3 minutes. Otherwise apply uniformly to wooden ends and joints with at least two coats. Apply the second coat after the previous coat has soaked in but before it is dry. Re-treat any surfaces cut after treatment. Note: The application of this product may cause darkening of some timbers. If colour is critical, try a test area first and allow to dry fully to ensure final appearance is acceptable.
After fully dry, glues, fillers and knotting can be used as normal. Bitumen, rubber and some plastic based materials may soften or swell on contact with fluid or solvent vapour. Ensure timber is fully dry (allow 6-8 weeks) or use a vapour barrier such as heavy duty polythene sheets (as used for damp proof membrane) before laying plastic floor tiles, foam or rubber-backed carpet, underlay or hanging vinyl wallpaper. Do not spill on tar, bitumen, bitumen felt, asphalt or mastics. When treating roof joists, first remove insulation and do not relay for at least 36 hours until treatment is dry.
2 to 5 days under average temperature and with good ventilation, but longer under less favourable conditions. 6 to 8 weeks before laying certain types of floor covering.
Clean equipment with white spirit. Remove as much preserver as possible from brushes before cleaning. For best results use Polycell Brush Cleaner. Do not use or store in extremes of temperature.
