Aquadecks is a non-film forming, water-based wood finish that provides a long-lasting, rich, matt finish for all woods, including exotic hardwoods.

Aquadecks saturates and stabilises wood which means it has minimal cracking, warping, and other damage caused by UV rays and moisture.

Where to Use Aquadecks

Aquadecks is ideal for garden decks, fences, garden furniture, or cladding. 

Surface Preparation

Surfaces must be thoroughly clean, dry and free of dirt, grease, grime, mildew and previous coatings.

Treat mildew with a 50/50 bleach/water solution. Scrub solution on to the surface and allow to stand for 10-15 minutes; rinse thoroughly.

After stripping and cleaning, allow the wood to dry for at least 2-3 days, or until it has reached a moisture content of 18% or less, before applying the finish.

Aquadecks can only be applied to bare wood surfaces or a weathered wood surface that was previously finished with Aquadecks.

ALL other finishes MUST be completely and thoroughly removed.

If necessary sand surface after stripping and cleaning (80 grit paper).

For Application Onto New Wood Surfaces

New wood surfaces have a hard shiny surface called mill glaze that prevents maximum penetration and bonding of any finish; this should be removed prior to application in order to ensure maximum performance of the finish.

Treat the surface with Owatrol Aquanett and then neutralise with Net-Trol. Alternatively, mechanically or manually abrade surface with 80 grit paper.

Clean off all loose wood particles.

Test wood for absorbency by sprinkling water on the surface. If water is absorbed rapidly, the surface is ready for finishing.

For Application Onto Untreated Weathered Woods

Untreated wood surfaces that have weathered longer than 6 months should be thoroughly cleaned with undiluted Net-Trol to ensure that all loose wood fibres, dirt, and other surface contaminants are removed prior to application of Aquadecks.

For Application Onto Previously Treated Surfaces (Oiled)

All oils or sealers must be completely and thoroughly removed with Aquanett and the stripped surface neutralised with Net-Trol before applying Aquadecks.

For Application Onto Previously Treated Surfaces (Paint, Stain, Varnish, Waterproofers Etc)

All previous coatings must be completely and thoroughly removed with Dilunett and the stripped surface neutralised with Net-trol before applying Aquadecks.

Note: Hardwoods including exotic hardwoods and woods rich in tannins i.e. Cedar, Douglas Fir, Teak, Ipe etc may darken with Aquanett and Dilunett but neutralising with Net-Trol immediately after rinsing will lighten and restore the wood's colour.


Apply 2 even coats of Aquadeck. The first coat of Aquadecks should be applied liberally and allowed to penetrate into the wood. The second coat should be applied as soon as the wet look of the 1st application has disappeared (normally 15- 20 minutes). For very porous surfaces a 3rd application may be needed.

Brush out any puddles within 20 minutes of applying the final coat to avoid Aquadecks drying as shiny spots on the surface.

Do not allow Aquadecks to become Touch Dry or Dry between applications. It must be applied 'wet on wet'.

Aquadecks is a penetrating finish and should not create a film on the surface as this will affect the coating's performance.


Maintenance is required once the treated wood appears faded or has a weathered grey appearance.

Clean surface thoroughly with undiluted Net-Trol before applying a maintenance application of Aquadecks.

Surfaces that are regularly exposed to the sun, weather or foot traffic will show wear more quickly than other areas. These areas can be cleaned with undiluted Net-Trol and Aquadecks can then be reapplied to the affected areas. The solution should be blended into areas which still have good colour.

For very porous or badly weathered surfaces a 2nd application may be required; this should be applied as directed under “Application” instructions above.

Areas that have maintained good colour do not need re-treating.

Decks and Other Horizontal Surfaces

Most decks and horizontal surfaces do not need re-treating every year.

A single application of Aquadeks every second year will be sufficient to refresh the natural beauty of the deck/horizontal surface and maintain protection.

Cleaning with Net-Trol once a year between treatments to remove dirt and contamination will renew the appearance of the wood.

For general re-treating follow directions under “Surface Preparation” and “Application”.

Cladding and Other Vertical Surfaces

Cladding and vertical surfaces do not require annual maintenance.

When Aquadecks shows signs of wear and weathering (turning grey) then a maintenance application is required.

Clean surface with undiluted Net-Trol and re-treat with a single application of Aquadecks according to “Application” instructions above, to replace material that has weathered out.

Clean Up

Aquadecks is a water-based product so tools can easily be cleaned using only soap and water.
