8.2.1.8. Shpaklevaniye and coloring
The set of types of body hard putties is issued, however, it is necessary to notice that the spackling paste attached to sets for repair of body panels with a hardener best of all is suitable for this type of works. To reach smoothness and correctness of a contour of the puttied surface, paste has to be applied with the flexible plastic or nylon pallet. Strictly following instructions of the producer of hard putty (violation can lead to the wrong hardening of spackling weight), involve insignificant amount of hard putty on a pure wooden or cardboard surface (carefully use a hardener).
Apply with the pallet hard putty on previously prepared surface of the damaged site of the body panel. For achievement of a desirable contour of a surface and level of hard putty each dab the pallet has to pass through all repaired surface. As soon as the contour of the puttied surface becomes close to demanded, immediately stop applying hard putty as it, stiffening, will begin to podlipat to the pallet, forming lumps and leaving vyryva on the processed surface. Continue to put paste layers with intervals about 20 миндо that time until the level of the puttied surface begins to act slightly over surrounding metal of the panel.
After hard putty hardening, remove its surplus with a file. Further the stage of a zashkurivaniye and grinding of the puttied surface begins. Best of all the waterproof emery paper is suitable for this purpose. Fill from coarse-grained paper No. 180 and further, consistently reducing granularity, finish No. 600. To reach adequate planeness of the processed surface, previously wrap up paper around whetstone from dense rubber (a tree or polyfoam) or paste on it. In processing regularly and often moisten paper with water. Such technology allows to reach absolute smoothness and flatness of the processed surface at the final stage.
As a result the processed surface has to be surrounded with a ring of pure metal. Wash out the processed surface clear water, washout about it everything formed dust during grinding.
From an aerosol barrel apply with a thin layer on the processed surface light primer, a so-called pro-attendance layer. It will allow to reveal all defects allowed during grinding which can be eliminated by drawing a new layer of hard putty. Repeat a zashkurivaniye and grinding. Repeat a shpaklevaniye, processing and primer of a surface before receiving satisfactory (on quality of the received surface) result. At the end wash out the processed surface water and dry up it.
Now the surface is ready to coloring. You apply paint from an aerosol barrel in dry rooms. If circumstances force to carry out coloring of a body in the open air, it is necessary to take the choice of suitable weather conditions seriously. If coloring of one panel of a body of the car is made, cover the intact panels surrounding it. This precautionary measure will allow to minimize effect of insignificant difference in tones of old and new paints. Such elements of finishing as the chromeplated decorative strips, door handles, etc., it is also necessary to cover (and it is better – to remove absolutely). For protection of the surfaces which are not subject to coloring use a special adhesive tape (painting "adhesive tape") and the old newspapers laid in several layers.
Before starting coloring from an aerosol barrel, carefully stir up it, then apply paint on a trial surface, fulfilling technology of coloring. Cover the surface prepared for coloring with primer in several stages. Without feeling sorry for water, a moisture resistant emery paper No. 600 process the grounded surface, trying to obtain its absolute smoothness. Before starting final coloring, let's primer dry out completely.
Put a paint coat, again trying to obtain the required thickness due to its repeated drawing. Begin coloring from the center of the repaired site, making a hand with a barrel roundabouts. Increase their radius, moving on a spiral until it is covered all damaged area and a part of an old paint and varnish covering on width about five centimeters. 10–15 min. later (not later not to damage the edge of the fresh paint beginning to stiffen) after drawing the last paint coat separate the covering surrounding panels of a body of the newspaper and an adhesive tape. Paint will finally be polymerized within about two weeks then, for smoothing of transition from fresh paint to put earlier, process the restored surface the thinnest grinding paste. In conclusion apply on the panel a layer of the protectant with wax.
