Preparing surfaces for painting.

Before painting the surface should be well dried, expansion cracks, grease them and zashpatlevat and then Primary coated, sanded and proolifit. In contrast to the primers used for distempers, oil primer is prepared on the basis of 50 g gustotertoy oil paint on 1 kg of linseed oil. To apply the putty composition, which includes linseed oil (500 g), drier (25 g), solvent (turpentine or varnish kerosene - 125 g), 10% solution of animal glue (100 g), soap (10 g) and chalk (2,5-3 kg). Most simple filler can be prepared from 1 liter of linseed oil and 1 liter of 10% glue solution, which was dissolved in a mixture of chalk. It dries in a day. Proolifku recommended before Filling (per day or two) with a continuous layer with no gaps. Large surface prooliflivayut primaries, brush and small - brushes, towels. Varnish type at hand, which is slightly squeezed. On the surface it is applied a thin layer of undulating movement of the wrist and shade in the transverse direction. Putty same surface before painting is better not to varnish, and primed with liquid paint (in 1 liter of varnish to add from 0.6 to 1 kg gustotertoy oil paint). The primer is good because it soaking in the filler leaves on its surface, albeit loose, coat of paint. This allows you to apply paint instead of just one or two instead of three - twice. Surfaces previously painted with oil paints, before re-painting should be well rinsed 2-5% solution of soda ash or warm water and soap. Without pre-washing the new paint will not adhere tenaciously to the old one. Not recommended for use with a solution of caustic soda, as it corrodes the paint. Weakened and falls behind the paint scraped from the entire surface with a spatula. Clean surface with a damp cloth, smooth out skin sanding, Coy, and again rub. If the paint is removed with difficulty, you can use a chemical process. To do this, use a paste prepared from 500 g sifted chalk and 500 grams of plaster of 20% solution of caustic soda. Soda solution take so much, that acquired the density of filler paste. Instead of plaster for making pasta, you can use the same amount of lime paste. Paste applied to the painted surface. After 30-90 minutes the paint is softened, and her clean off with a scraper or steel trowel. To remove oil paint on the floors, you can use 20% solution of caustic soda. Remove oil paint from the wooden floor can be a different way. The board is wetted with water and poured on top a thick layer of soda or caustic soda. After that, the floor is closed wet burlap, from time to time moisturizing it. And you can lay on top of burlap polyethylene film, then the burlap will not need extra moisturizing. A couple of hours the paint swell, and it can be easily removed with a knife or a loop. Work carried out in rubber gloves. Remove the old oil paint by using a blowtorch, heating and cleaning mellowed layer with a spatula. If you can not work with an open flame, then soften the paint in small areas can be electric irons, proglazhivaya it through the foil. Peeled paint surfaces thoroughly washed with water and neutralize any acid, eg 1 - 2% solution of acetic acid. Then again washed with water, dry rub, grind the abrasive cloth, close up the cracks and covered with drying oil. Cracks in the floor up to 5 mm obscure the mastic of the five parts by weight of cement, 14 parts water and two pieces of wood glue. Clay boiled in water until it is completely dissolved. Then adds cement, sawdust, dry paints in the color and mix all thoroughly. Mastic putty in cracks in the floor with a spatula, carefully leveled it and then dry sanded sanded. Apply paste to the warm day cooking. To paste does not get cold, put it in a bowl with hot water and maintain low temperatures. Filling one time, usually not enough. If after the second time left a small crack, it's not scary. But if you have floors covered with lacquer, but not painted, they can and the third time proshpatlevat cracks. Metal surfaces are cleaned with a wire brush the rust and dirt. All metal, plaster and wood surfaces to be covered with oil paint, must be pre-Primary coated with drying oil. This increases the adhesion between the surface and paint. Rusty spots on the plaster and soot washed off vitriolic composition (per 1 liter of boiling water take from 50 to 100 g of copper sulfate), and grease stains - hot with a 2% soda solution. If the spots the plaster is not removed with a solution of vitriol, they should paint the zinc white. Stains on walls and ceilings were washed with 1 or 2 times, preventing splashing of the solution.
