Product Description

Owatrol H4 Wood protects new timber as it ages and becomes a natural grey colour.

Owatrol H4 Wood has been formulated to protect your exterior timber surfaces as it ages and becomes a natural grey colour without causing damage to the timber. H4 Wood contains a blend of ingredients that dramatically reduce water absorption into the timber. This hydrophobic treatment will help increase the life of the timber by stabilising the internal structure of the wood, preventing it from splitting and cracking. Owatrol H4 Wood will protect softwood and hardwood, vertical and horizontal timber surfaces.

Owatrol H4 Wood is an easy to apply wood protector and is highly compatible to other wood products available. It also prevents the growth of moss and dirt. H4 Wood is a completely colourless product and will not affect the colour or change the appearance of the timber.

Best Uses

Owatrol H4 Wood is suitable for use on exotic hardwoods and for untreated and pressure treated softwoods, on both vertical and horizontal surfaces. Owatrol H4 Wood can be used on wood that has already greyed naturally, maintaining and protecting it from environmental attack from UV rays and damage from weathering. Use Owatrol H4 Wood as a protective base coat before applying a wood finish coat on cladding, garden furniture, sheds, garden rooms, gazebos, etc.

Application

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

Owatrol H4 Wood and Stone can only be applied to bare wood surfaces or weathered surfaces previously finished with Owatrol H4 Wood and Stone. H4 may also be applied to surfaces previously finished with Owatrol penetrating products Owatrol Textrol, Owatrol Aquadecks without the need for stripping. Contact us for additional information and advice before proceeding. ALL other finishes MUST be completely and thoroughly removed. If necessary sand (80 grit or coarser depending on wood species) surface after cleaning and/or stripping. Thoroughly dust off.

New wood:
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 water is not absorbed then proceed as follows: Treat wood with Owatrol Aquanett or Owatrol Prepdeck, neutralise with Owatrol Net-Trol, alternatively mechanically or manually abrade surface with 80 grit paper or coarser depending on wood species. Clean and dust off to remove all loose wood particles.

Weathered wood surfaces (untreated):
1 – To keep the grey look of the wood clean with Owatrol Soapclean.
2 – To restore the colour of the wood clean with undiluted Owatrol Net-Trol to remove all loose wood fibres, dirt and other surface contamination.

Previously treated surfaces (oiled, paint, stain, varnish….):
All previous finishes must be completely and thoroughly removed.

Oils and sealers: Strip with Owatrol Aquanett or Owatrol Prepdeck, neutralise with Owatrol Net-Trol.
Solvent (oil or alkyd based finishes): Strip with Owatrol Dilunett, neutralise with Owatrol Net-Trol.
Acrylic finishes (Water-based): Strip with Owatrol Prepdeck, neutralise with Owatrol Net-Trol.
Other finishes e.g. 2 pack epoxies, urethanes...: Strip with Owatrol DSP800, neutralise surface with a suitable solvent – Acetone, White Spirits, Methylated Spirits.

Note: Hardwoods inc. exotic hardwoods and woods rich in tannins i.e. Cedar, Douglas Fir, Teak, Ipe, Iroko…. may darken with Owatrol AquanettOwatrol Prepdeck and Owatrol Dilunett, neutralising with Owatrol Net-Trol immediately after rinsing will lighten and restore the wood's colour.

New Stone:
Clean with Owatrol Soapclean to remove any dust, dirt and other surface contamination. Allow to dry 24 hours.

Heavily Soiled and Dirty Stone:
