  • For the dilution, it is of paramount importance to use Thinner 9800 for nitrocellulose Lacquer;
  • Contact with humidity may highlight the bleaching of the surface due to the feature of a  product with a nitrocellulose base;
  • Removers and resins can cause problems of drying and finishing in the coatings applied after the removal. If you use removers, clean the wood effectively to minimize the  occurrence of these problems;
  • Contaminations on the surface can delay the drying of the product. In these cases, we suggest bathing them successively with Eucatex Thinner until the complete decontamination of the wood;
  • The practical yield can vary due to the method of application, geometry of the structure, rugosity and absorption of the surface, thickness of the product layer deposited, atmospheric conditions and application technique.

According to ABNT NBR 13.245.

  • Preparation: the surface must be firm, cohesive, clean, dry, without dust, fatty materials, and mould.
  • Surfaces with gloss: they should be sanded until the complete removal of the previous finishing before starting to apply the sealer.
  • Surfaces with fatty stains: they should be washed with a solution of water and neutral detergent. Then, rinse them well, wait for them to dry and apply the product.
  • New woods not dry: they must receive successive applications of Thinner until the complete elimination of the natural resin of the wood, which can damage the paint.
  • New dry woods: sand the surface to eliminate splinters, remove the residue and clean with Eucatex Thinner.
  • Repainting: remove loose flakes, sand to remove the gloss and make a new application.
