ACS Woodbead Water Repellent for Wood
£18.00 – £33.00
+ VAT & delivery
ACS Hydrobar® Woodbead is a single-pack, waterborne impregnating water repellent for exterior softwood joinery. Once completely cured, the product has high water-shedding properties and a long-lasting, pronounced beading effect.
Woodbead is suitable for applications on to bare softwoods and hardwoods*.
Laboratory testing has shown marked reduced levels of water uptake, even after 4000 hours QUV (approximately 10+years). Noticeable beading on field trial product, even after 17 years exposure in an Alpine environment.
*The life expectancy on less porous hardwoods may be reduced.
- Imparts water and dirt resistance to exterior timber joinery such as cladding, sheds, fences, decking and seats.
- Protects timber from moisture but allows the joinery to age naturally. Woodbead contains no fungicides or UV controlling pigments but will inhibit organic growth through its water repellent properties.
- Improves the life expectancy of timber species vulnerable to decay, such as pine and lower grade softwoods.
- Woodbead can be used with the ACS Timber Treat (see separate data sheet) if control of sap stain and wood decay fungi is required. Apply the Timber Treat one to two days prior to application of the Woodbead to allow time for it to be absorbed by the timber and begin its work.
After application, Woodbead leaves little or no visible signs of application, except areas treated with
Woodbead will not darken when wet.
Ensure all surfaces are clean, dry and free of oil, grease and loose or flaking material such as bark. Remove all organic growth such as mosses, lichens, moulds and fungi.
Lightly abrade glossy surfaces of prepared timber (PAR) with wire wool or medium grade Aluminium Oxide paper to reduce surface tension and increase porosity.
Rub down old, ‘silvered’ timber should to remove degraded material to expose new wood. Mask off any glazing and cover plants. If spraying, do not allow spray-drift to come into contact with sensitive surfaces, such as vehicles.
A single-pack, ready-to-use aqueous solution, of functional silicone resin.
Does not significantly alter the essential colour and tone once dry.
Colour: Milky white (dries clear).
Touch dry @ 20°C: 1-2 hours.
Surface dry @ 20°C: 2-3 hours.
Shower proof @ 20°C: After approximately 24 hours depending on drying conditions.
Full Protection: Up to 4 weeks after application.
Clean up: Water. Remove as much material from application equipment as possible prior to cleaning.
Shelf-life: Approximately 12 months in unopened containers.
Theoretical Coverage: 4-8 m²/litre depending on porosity of timber.
Woodbead is suitable for application to bare timber. Any paints, stains or varnish must be completely removed prior to application.
Product may settle during storage and transport, so shake the contents before and periodically during use.
Apply by brush, deep pile roller or conventional garden sprayer.
Apply an initial coat, starting from the top of the area, working down the surface and allowing excess liquid to run down. Once the whole surface has been treated, but before the initial coat has dried, apply a second coat (wet-on-wet application). Once completely dry, further applications may not be adsorbed.
Limitations of Use
Do not apply if there is a likelihood or rain, fog or frost before the coating has completely dried.
Do not apply if the surface is wet or if within 3°C of the dew point.
Surfaces treated with Woodbead will not accept waterborne or solvent-based paints until several months of weathering has taken place.
Remove splashes from glass and plant life immediately or cover prior to application.
