Water–repellent agents “Неогард” for wood: application manual
Water-repellent agent “Неогард” for wood” is supplied in the form of two solutions. Before using the solution №2 is poured into the solution №1 followed by good mixing (shaking), after this the composition is ready to use. The mixed composition may be stored for several weeks in the closed (but not hermetically) container.
The application and drying works should be held in the well aired rooms or at the open air. The compositions are applied in one layer by brush, applicator roll, sponge or sprayer in amount enough to wet the surface but without runs. The composition surplus should be removed. The treated articles should be conditioned for several hours (at room temperature), after this they are ready for use. At lower temperatures the conditioning time increases.
Composition application should be held in protective glasses and gloves, when sprayer is used respirator is needed. Before final curing the composition is flammable.
The surface treated should be clean and dry (in case of humid wood the penetration depth decreases drastically). Any treatment with nonfilm forming compositions (mordants, fire retardants, antiseptics) should be held before waterproof treatment. It is not recommended to be used for the article treated before with drying oil, lacquers, paints or another film forming compositions.
For painting of wood articles treated by water-repellent agent “Неогард” for wood alkyd based paint should be used.
Consumption is 0.1 – 0.15 l/m2. The increasing of the applied composition does not improve the water-repellent properties but lead to formation of rubberlike film at the wood surface.
During composition storage the influence of increased temperatures (over +35°C) and direct sunlight should be excluded. Low temperatures and frost are not dangerous for the composition.
