Nowadays, wood is practically no longer treated, so one of the problems you have to face
after painting the facade is the release of resin in the places of the branches. If the tone is darker, then the resin is released more intensively. In order to qualitatively prepare the timber before painting, Paint Eco has developed a Shellac solution for the branches, which forms a lacquer layer and limits the release of resin. Shellac is a natural wood preservative historically used for furniture polishing and restoration work that protects the surface and adds shine. Shellac is traditionally applied in a thin layer with a brush, but in the past, the shellac polishing method was also used for furniture, which gives the surface a depth effect. For polishing, a woolen sponge soaked in shellac was used and with which the lacquer was rubbed into the surface in circular motions. Polishing requires skill.
Shellac has excellent compatibility with oil coatings and linseed oil paint.
Application. External works and internal works. In outdoor works under linseed oil paint.
Treatment of branch sites.
Surface preparation. Before applying shellac, the area of the branches must be cleaned.
Dry resin parts are cleaned mechanically. Sticky resin residue can be dissolved with turpentine and wiped off with a piece of cloth. The surface must be dry.
Work progress. Shellac is applied with a brush in a thin layer. For larger areas of branches, it is recommended to apply shellac in 2 layers. When the shellac layer is dry, it is lightly sanded with fine sandpaper. Shellac dries in about 15 minutes, but painting should be done the next day. Shellac is applied before painting the surface with linseed oil paint. After the branches have been treated, the surface is lubricated with Paint Eco linseed oil primer. We recommend adding approximately 10% of the selected color tone to the primer. The primer will form the base for the linseed oil paint to cover with an even shine. Next, two thin layers of paint are applied, allowing each layer to dry.
Restoration of a previously painted surface. If you spread the resin on a surface previously painted with linseed oil, then proceed in the same way as in the section Preparation of the surface and applying two layers of shellac to the area of the branches. In this case, the surface is not primed, but a restorative layer of linseed oil paint is applied.
Restoration works. Shellac is used in window restoration to treat a glass groove
impregnated with pernitsa. Such treatment ensures that when applying linseed oil putty, the wood does not take linseed oil from it and the putty remains flexible and does not crack.
Clean brushes with alcohol.
