Where to use
Ultra Tough Decking Stain is formulated for use on new or existing wooden decks. For maximum performance Ultra Tough Decking Stain should be applied to all sides of wood including the undersides prior to laying decking.

How much is needed
A 2.5L tin is normally sufficient for: Bare & previously stained wood: 20m² with 2 coats. Absorbent wood, sawn wood and grooved decking will reduce coverage.

Preparing the job
Timber specifically sold as decking is normally pretreated with wood preserver to prevent decay. Ensure timber used in ground contact has been pre-treated or sold specifically for use as decking. Surfaces should be clean, dry and free from algae and mould. For best results brush to remove dirt and debris and then clean the surface with Cuprinol Decking Cleaner. Rinse well and allow to dry. Resinous or oily wood may affect performance.

New wood: Wipe with white spirit to remove any natural oils/resins.
Weathered wood: Completely remove all grey wood by sanding back or using Cuprinol Decking Restorer.
Painted or varnished wood: Sand off or chemically strip existing coatings then treat as bare wood.
Previously treated wood: Wash with Cuprinol Decking Cleaner and water to remove dirt and grease and allow to dry.

How to apply
Stir thoroughly before use. Final colour will depend upon wood type, previous treatment and the number of coats applied. Apply 2-3 coats evenly along the grain, avoiding overlaps. When applying subsequent coats, allow each coat to dry fully before recoating. Avoid heavy wear and tear for a few days after application. On previously stained decking, touch up bare areas and allow to dry before finishing with further coats. Do not apply in temperatures below 5C, in damp conditions or if rain is likely before the product has dried. If using more than one can it is advisable to mix them together in a larger container or finish in a corner before starting a new can.

Drying time
2-6 hours. Drying times can vary depending on the nature of the surface and the weather conditions.

Cleaning and storage
Remove as much stain as possible from brushes and rollers before cleaning with water. Do not use or store in extremes of temperature or wet conditions.
