Cuprinol Woodworm Killer (WB) is a clear water-based low odour formulation that kills all types of woodworm. Its deep penetration prevents re-infestation and ensures effective protection for years to come. Do not use on beehives or bee keeping equipment.
Coverage can vary depending on application method and the condition and nature of the surface.
Treat bare wood by flooding the surfaces with 2 or 3 brush coats. Pay particular attention to end grain, corners, joints, crevices, etc. Re-treat any surfaces cut after treatment and all replacement timber. To treat existing attacks of wet or dry rot use Cuprinol 5 Star Complete Wood Treatment(WB)*. This product may cause darkening of some timbers. If colour is critical, apply a test area first and allow to dry fully to ensure final appearance is acceptable. Most decorative finishes such as solvent based or water based paints, woodstains, varnishes, polishes etc can be applied after the fluid has dried. Rough sawn timber will absorb up to twice as much as planed wood. Eradication of insect attack including House Longhorn Beetle: Brush 2-3 uniform coats. Use a minimum of 1 litre per 3.5-5 sq. metres of timber. Replacement timbers liable to House Longhorn and woodworm attack: Dip for at least 3 minutes or brush 2-3 uniform flood coats. Use a minimum of 1 litre per 3.5-5 sq. metres of timber. Ensure timber is fully dry (allow 3 days) before laying plastic floor tiles, foam or rubber backed carpet, underlay, insulation in lofts, etc. After full drying, most glues, fillers and knotting solutions can be used as normal.
Treatment is usually dry within 1 - 3 days. Drying time may be extended in confined areas such as under floors and in roof spaces.
Do not use or store in extremes of temperature or wet conditions.
