product information

Details

H4 Wood is a colourless, waterproof protection for wood which allows it to age naturally and turn grey without damage from water, pollution, moss and dirt.

Perfect if you like the natural look of wood as it turns grey but are anxious to prevent damage such as splitting and cracking which will happen if wood is left untreated.

H4 Wood is hydrophobic and therefore water repellent, it is completely clear and will have no effect on the colour or appearance of the wood being treated.

It is silicone free and helps to prevent environmental attack including from mould and water.

preparation

Details

Before Using Owatrol H4

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

Treat any mildew with a 50/50 bleach/water solution.

Scrub the solution on to the surface and allow it to stand for 10- 15 minutes before rinsing thoroughly.

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

H4 Wood can only be applied to bare wood surfaces or weathered surfaces previously finished with H4 Wood.

H4 Wood may also be applied to surfaces previously finished with Owatrol penetrating products including Textrokl and Aquadecks without the need for stripping.

 ALL other finishes MUST be completely and thoroughly removed.

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

New wood surfaces

Test wood for absorbency by sprinkling water on the surface. If water is absorbed quickly, the grain is sufficiently ‘open’ and the surface is ready for finishing, proceed to Application. If the water is not absorbed then proceed as follows:

  • Treat wood with Aquanett or dilute Prepdeck
  • Then neutralise with Net-Troll

Alternatively mechanically or manually abrade surface with 80 grit paper and then clean and dust off to remove all loose wood particles.

Weathered wood surfaces (untreated)

To keep the grey look of the wood clean with a light detergent. 

To restore colour of wood clean with undiluted Net-Trol to remove all loose wood fibres, dirt and other surface contamination.

Previously coated surfaces

All previous coatings must be completely and thoroughly removed.

  • Oils and sealers: Strip with Aquanett or Prepdeck then neutralise with Net-Trol
  • Solvent (oil or alkyd based finishes): Strip with Dilunett then neutralise with Net-Trol
  • Acrylic finishes (Water-based): Strip with  then neutralise with Net-Trol
  • Other finishes i.e. 2 pack epoxies, urethanes… Strip with DSP 800then clean the surface to remove residual paraffin

Note: Hardwoods and woods rich in tannins e.g. Oak, Chestnut, Douglas Fir, Cedar, etc. may darken with Aquanett, Prepdeck and Dilunett neutralising with Net-Trol immediately after rinsing will lighten and restore the woods colour.
