  • Designed as a low VOC, high performing alternative to traditional decking oils with superior performance.
  • Deeply penetrates into the wood to enhance resistance to water swelling that can cause wood cracking and warping.
  • The stain leaves a natural surface appearance and leaves a coating that will not crack, flake or blister.
  • Long lasting and durable, Timbashield Decking Protector maintains a high level of water resistance on horizontal surfaces that are prone to extended contact with water.
Directions for Use

Surface Preparation

Shake / mix well before use and frequently during application (thorough mixing is needed to ensure a consistent colour throughout the treatment).

New Bare Decking Boards: Ensure the surface is clean, dry and free from contamination.

Previously Coated Decking Boards: Decking Protector has been designed to be used on bare, uncoated decking boards so it can soak deeply into the wood fibres and give optimum performance. Any old, loose or peeling coatings should be sanded back and the quality of the sanding will influence the finished result. If previous coatings are not entirely removed the product may not be fully absorbed, potentially causing patchiness.

Surfaces already coated with Timbashield Decking Protector should be allowed to naturally weather for at least a year and do not need the additional sanding step and just need to be thoroughly cleaned before reapplication.

Old Decking Boards: Panels that have decayed or become damaged should be removed and replaced. Brush with a stiff brush to remove any dirt that has become ingrained. Mould, algae and fungi must be removed and treated with a suitable wood cleaner.

Please note that the condition of the decking boards will influence the final colour and appearance. A test patch is always recommended.


Only apply the product onto wood that is fully dry. Ensure the temperature is between 5 and 25 degrees Celsius and there is no imminent rain forecast. Do not apply in damp or humid conditions. Failure to meet these requirements may adversely affect the drying and durability of the finish.

Brush: Start in the furthest corner and using a good quality brush, apply along the length of the board in the direction of the grain.

Brush out thoroughly and do not leave pooling or any areas flooded or this may lead to patchiness.

Apply a second coat within 4-6 hours.

The second coat may be slightly more difficult to apply due to the water repellent nature of the first coat. Brush back and forth to work the product into the coating below and allow the second coat to be deposited.

Due to the uneven surface of decking, two coats is required to ensure full coverage and optimum performance.

Allow 24 hours until walking on the surface and replacing furniture. Hard abrasion should be avoided, and heavy furniture should not be places on the decking for a week after application.

Low temperatures, increased humidity and ingredients of some wood types may increase drying time.


During application, remove any excess with a clean cloth. Any spillages should be cleaned up as quickly as possible.

Although a water based product, brushes must be washed with white spirit due to the high content of hydrophobic oils and wax. Washing with water is not suitable. If wax builds up on the brush mid-application, wash with white spirit before continuing to will improve the ease of application.

Storage and Shelf Life

The product should be stored in frost- free conditions. Recommended shelf life is 12 months from date of manufacture. If you wish to use the product after this time, stir well and trial before use.

Product Details & Features

Decking Protector is low odour, non flammable and contains low levels of VOCs.

Available in a range of natural colours that brighten, re-colour and enriches the natural appearance with UV absorbing pigments that help to prevent further aging.

Timbashield Decking Protector also extends the lifespan of the wood by adding a film that is resistant to fungal growth.

Note: The finished surface is influenced by several factors including wood species, previous treatments that may have been used, and the condition of the wood, therefore a trial application is always required.

Waterproofing Technology

Timbashield Decking Protector contains a blend of oils and wax that impregnate the wood, soaking into the pores and providing protection from within, rather than just at the surface.
Oils penetrate deeply into the wood whilst wax works on the upper layers to give double action protection against the effects of prolonged water contact that can occur on horizontal surfaces.

Can I use this product on decking that has been treated in the past?

Yes, but only if the decking is prepared properly first. If a paint has been used it must be fully removed and sanded back. If a stain has been used it must be allowed to weather naturally before treating. If these steps are not followed the coating will sit on the surface and give a patchy finish and reduced performance.

Why do I need to wash brushes with white spirit when this is a water-based product?

Although water-based, the product contains a lot of oils and wax to give the best water-resistant protection. These are soluble in white spirit, rather than water alone, and so this must be used to remove residues from the brush.

Can I lighten a darker stain by adding a lighter one on top?

No, even a light stain, when applied to a dark base, will deposit more colour and give a darker finish.

How often will my decking need restaining?

This depends on how exposed the decking is and the amount of heavy footfall. We recommend redecoration every 1-2 years as required.

How long do I have to wait before walking on my decking?

We recommend waiting 24 hours until walking on the treated surface, although longer if possible before replacing heavy furniture.
