Wood cleaning: Before any protection or maintenance action, the supports should be well prepared. Indeed, a finish cannot be applied if the surface has only been briefly sanded or vaguely cleaned with a water jet. The wood must be healthy, free of stains or residues, otherwise they will be accentuated once the finish has been applied or even damage it.
If the wood is covered with an old film-forming finish, it must be completely rid of it, the only effective action is then stripping.
Owatrol's Dilunett stripper allows you to find a support like new by eliminating any old film-forming finish.
Dilunett or how to strip up to 8 layers of paint or stain: the gel formulation of Dilunett and its extreme wetting power allow it to remove all old layers (up to 8) of stain paint or varnish and to remove stubborn tasks.
The plus: solvent-free, Dilunett does not dry out and remains active for a long time, which guarantees the total elimination of the various coatings.
NB: you must always neutralize a support after using Dilunett, The Net-Trol 200 of Owatrol makes it possible to carry out this operation.
