Net-Trol is a powerful wood cleaner and brightener which restores grayed and weathered wood to its natural color without damaging the wood’s fibers. It effortlessly removes both surface and ground in dirt leaving the wood looking bright and vibrant. Net-Trol is fast acting and can restore the original color of your wood surface in as little as 15 minutes with no laborious and backbreaking sanding!

It is safe to use on all exterior wood types and is also an excellent degreaser for use on tropical hardwoods to allow finishes like Deks Olje D1 to penetrate. Net-Trol can remove stains caused by tannin bleed and will remove all traces of weathering caused by mildew, pollution and UV rays. It will also neutralize wood surfaces which have been stripped with a stripping product such as Owatrol’s Aquanett or Prepdeck, leaving the surface ready for applying your chosen finish.

Net-Trol is not only for use on wood surfaces though – you can also use it to restore the luster to faded plastics dulled by weathering and UV rays. It can also be used to remove rust stains and to clean discolored stone and cement. Net-Trol is biodegradable and does not contain solvents or bleach. It’s not harmful to plants and shrubs so it’s safe to use in the garden!

Applying Net-Trol to wood, stone, concrete

First wet the surface with fresh, clean water. Then apply Net-Trol with a synthetic brush or roller (medium or long pile). Scrub the surface with a stiff nylon/synthetic brush. Leave it to stand for approx 10-20 minutes. If the surface starts to dry, dampen it with a mist application of water. Scrub the surface whilst rinsing with water or use a pressure washer (max. 60 bar). If required, repeat the procedure. If applying to wood, allow it to dry for 48 hours before using your chosen finish. If applying to stone or concrete allow it to dry until it meets the moisture content required by any chosen finish or sealer if appropriate.
