Breathable exterior wood sealer for all external softwood and hardwood surfaces

Exterior Wood Sealer is a subsurface sealer & preserver for exterior wood. Suitable for use to seal sheds, fences, tables, chairs, workshops & decking with an invisible protective seal.

This natural wood sealer creates a powerful water repellent surface, it is highly resistant to UV light & moisture penetration. The application of this product extends the lifespan of exterior wood by inhibiting the growth and staining of moulds & algae.

Invisible Wood Sealer

Highly suited when sealing surfaces located in damp climates and shaded areas. Can be applied to softwood or hardwood to resist rotting and warping. Apply to Oak, Beech, Pine, Red Cedar, Douglas Fir & more. Up to 10 years protection from the elements.

Apply via low pressure pump-up garden sprayer or brush, work the product into the surface with a brush (if required). After each application any run off can be worked back into the surface with brush. The sealer will penetrate the surface of the wood creating a water repelling barrier. This in turns inhibits the growth of organic contaminants such as green algae & also acts as a barrier against damp.

This sealer is an invisible sealer which does not alter the appearance of the wood. Perfect for protecting exterior wood without altering its natural appearance.

Available in 5 litre, 10 litre, 15 litre & 20 litre container with free economy shipping and express delivery shipping options. Samples are available via the select size button.
