Surface preparation

General Directions:

Surfaces must be 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 surface and allow to stand for 10-15 minutes; rinse thoroughly.
After cleaning, allow wood to dry 2-3 good drying days or until it has reached a moisture content of 18% or less before applying D.1 PRO.
D.1 PRO may only be applied to bare wood surfaces or a weathered wood surface that was previously finished with D.1 PRO.
ALL other finishes must be completely and thoroughly removed. If necessary sand surface after cleaning and/or stripping (80 grit paper).

New wood surfaces:

New wood surfaces have a hard shiny surface called mill-glaze that prevents maximum penetration and adhesion of any finish, this should be removed to ensure maximum performance the finish.
Treat with Aquanett or Prepdeck and neutralise with Net-trol.

Weathered wood surfaces (untreated):

Wood that has weathered longer than 12 months or turned grey should be cleaned with Net-trol to remove all loose wood fibres, dirt and other surface contaminants. If wood is severely contaminated, clean with Prepdeck or Aquanett and neutralise with Net-Trol.

Previously oiled surfaces:

All other oils or sealers must be completely and thoroughly removed with Aquanett or Prepdeck and the stripped surface neutralised with Net-trol.

Previously coated surfaces (paint, stain, varnish etc):

All previous coatings must be completely and thoroughly removed with Dilunett, Prepdeck or DSP 800.
Solvent (oil or alkyd based finishes): Strip with Dilunett neutralise with Net-trol.
Acrylic finishes – Water-based: Strip with Prepdeck neutralise with Net-trol.
Other finishes i.e. 2 pack epoxies, urethanes etc Strip with DSP 800.

Note: Hardwoods including exotic hardwoods and woods rich in tannins i.e. Oak, Chestnut, Teak, Ipe, Bangkarai etc may darken
with Aquanett, Prepdeck or Dilunett, neutralising with Net-trol immediately after rinsing will lighten and restore the wood’s colour.


Thoroughly remove any existing coatings with DSP 800 or by mechanical abrasion.
Sand surface with 80 or 100 grit paper to open the woods’ pores.
Dust off and wash with Methylated Spirits (Denatured Alcohol), Acetone or similar (NOT White Spirit) to degrease the surface.
Allow to dry.


Shake or stir can well before use.
Start by applying a 1st liberal application of D.1 PRO to an area that can be treated in 15 minutes and allow to penetrate (normally 15-30 minutes).
Apply a 2nd application as soon as the first has penetrated and allow to penetrate.
Continue this “wet-on-wet” application of D.1 PRO until wood is saturated i.e. will accept no more oil.
Leave final application 20-30 minutes then brush out or wipe up excess product that has not penetrated to avoid shiny spots.
Do not allow D.1 PRO to become Touch Dry or Dry between applications.

D.1 PRO is not a surface coating, it’s place is in the wood not on the surface. D.1 PRO protects by penetrating the wood, providing a rich matt finish.

Clean up

Clean all tools and equipment with white spirit whilst still wet. If allowed to dry remove with paint stripper.
Any rags etc soaked in D.1 PRO may spontaneously catch fire if improperly discarded. Rags etc must be saturated with water or placed in a sealed water-filled container and disposed of according to local regulations.


D.1 PRO will gradually lighten over time due to exposure to the sun and UV rays.
Maintenance is due when the finish has severely faded. Surfaces with harsh exposure to the sun, weather and foot traffic will show wear more quickly than other areas.
Areas retaining good colour do not need re-treating.
Clean surface with Net-trol.
Re-apply D.1 PRO as directed under “Application”.

Things to remember

Cover everything you do not wish to coat.
Apply between 5°C and 35°C. Do not apply in direct sunlight or hot surfaces. Wood surfaces in direct sunlight can reach temperatures of 60°C even when the air temperature is 35°C.
Do not apply if cold and/ or wet weather is expected within 24 hours.
Always work the entire length of a board or piece of wood to a logical break. Never stop application in the middle of a board or piece of wood.
Vertical cladding should be coated from top to bottom.
After spray application, always back-brush or back-roll to improve penetration and uniformity of coverage.
Ensure wood is dry – max 18% moisture content.
Do not allow to dry between coats – apply D.1 PRO wet-on-wet.


The tannins and natural oils in wood such as Iroko, Azobe, Padouk impede the penetration and drying of finishes. These wood species should be thoroughly prepared or allowed to weather for 12 months before applying D.1 PRO.

    Had Iroko gates fitted 3 years ago and told to use Tung oil on them to maintain them – This left them black and looking awful.
    Just finished using Aquanett, Net-Trol and D1 pro, on them and they now look as new. Really good products that really work. Could not recommend them enough.
