1 00:00:00,000 --> 00:00:29,980 Thank you very much. 2 00:00:30,000 --> 00:00:59,980 Thank you. 3 00:01:00,000 --> 00:01:08,000 When a painting process is carried out by a vehicle in the workshop, it is about reproducing the layers applied during the manufacturing phase. 4 00:01:08,000 --> 00:01:25,000 To show the painter his characteristics , the painter must observe some standards established and collected by the painters in their technical sheets 5 00:01:25,000 --> 00:01:31,000 in terms of mixing proportions, viscosity, evaporation times and drying, among other factors. 6 00:01:35,000 --> 00:01:41,000 After the painting process, it is usual to achieve a quality work both in the background and in the finish. 7 00:01:41,000 --> 00:01:49,000 However, defects may appear due to very diverse causes that could only influence the visual aspect of the paint layer 8 00:01:49,000 --> 00:01:59,000 or even affect their functions and properties and that lead to an important deterioration of the system or of the support itself if they are not corrected or eliminated quickly. 9 00:02:10,000 --> 00:02:14,000 Defects can appear unpredictably due to climatic factors, 10 00:02:14,000 --> 00:02:18,400 although the vast majority of them arise from causes that are not alien to the painter, 11 00:02:18,400 --> 00:02:22,199 such as the cleaning in the process, the preparation of the surface, 12 00:02:22,199 --> 00:02:27,199 the preparation, application and drying of the product and the maintenance of the equipment. 13 00:02:33,199 --> 00:02:39,199 There is no doubt that the best way to solve a paint defect is to prevent it from being produced. 14 00:02:39,200 --> 00:02:44,200 For this purpose, the painter must be properly trained and have the necessary means. 15 00:02:44,200 --> 00:02:46,200 Equipment in optimal conditions, 16 00:02:46,200 --> 00:02:49,200 products suitable to temperatures, 17 00:02:49,200 --> 00:02:51,200 proportions of correct mixtures, 18 00:02:51,200 --> 00:02:54,200 proper evaporation and drying times, 19 00:02:54,200 --> 00:02:56,200 meticulous cleaning. 20 00:03:02,200 --> 00:03:06,200 It is important to know and recognize in which layer of paint the defect has been generated, 21 00:03:06,200 --> 00:03:12,520 where it is located and the cause that has originated it, then the causes or phases of the 22 00:03:12,520 --> 00:03:16,040 process are analyzed in which different paint defects originate 23 00:03:20,920 --> 00:03:27,200 surface cleaning the cleaning of the painting area is essential it must be done immediately 24 00:03:27,200 --> 00:03:31,960 after sanding and always before applying a product on the 25 00:03:31,960 --> 00:03:36,760 support the absence of cleaning a insufficient cleaning can cause 26 00:03:36,760 --> 00:03:42,420 defects such as lack of adherence and dust spots on the finish layer 27 00:03:47,400 --> 00:03:52,040 preparation of the paint area the appropriate preparation of the surface and 28 00:03:52,040 --> 00:03:55,580 of the layers that will serve as a support to the finish paint avoids 29 00:03:55,580 --> 00:04:01,140 irregularities on the surface marks of sanding and smudging 30 00:04:01,960 --> 00:04:24,060 The preparation of the product, the improper use of diluting and additive catalysts and its incorrect preparation, ignoring the manufacturer's technical recommendations, can cause blockages, bleeding, sluggishness in drying, among other defects. 31 00:04:24,060 --> 00:04:37,959 application of the product the incorrect application of paint products is one of the main causes 32 00:04:37,959 --> 00:04:46,379 of defects especially in the layers of finished hanging orange peel pulverized formation 33 00:04:46,379 --> 00:04:51,920 of shadows, etc. 34 00:04:51,920 --> 00:04:56,000 From the point of view of the application, special attention must be paid to the number 35 00:04:56,000 --> 00:05:00,579 of hands, the slap, if it is wet or dry. 36 00:05:00,579 --> 00:05:05,740 As for the technique, the distance, the spray and the pressure of application will be monitored 37 00:05:05,740 --> 00:05:06,740 . 38 00:05:06,740 --> 00:05:12,439 Finally, the setting of the gun and the evaporation times between the hands must be controlled. 39 00:05:16,379 --> 00:05:35,639 Drying of the paint. An inadequate adjustment of the equipment, the temperature or the drying time can cause, among other inconveniences, loss of brightness, veiled and boiled. 40 00:05:35,639 --> 00:05:47,639 Climatological factors such as high humidity can prolong the drying time of the products 41 00:05:47,639 --> 00:05:51,199 and cause stains and bubbles in the finish layer. 42 00:05:51,199 --> 00:05:56,539 On the other hand, high temperatures increase the appearance of defects such as orange peel, 43 00:05:56,539 --> 00:06:00,099 loss of brightness, sprays and splashes. 44 00:06:00,100 --> 00:06:05,100 it is necessary to choose the right diluents and catalysts for the right temperature. 45 00:06:13,100 --> 00:06:16,100 The defect must be taken into account in the area where the defect has occurred, 46 00:06:16,100 --> 00:06:22,100 since in very visible parts, such as hoods, fins and doors, its existence is of great importance. 47 00:06:22,100 --> 00:06:29,100 But this same defect may have less transcendence in pillars, strips, door sills or none, 48 00:06:29,100 --> 00:06:34,980 are interior pieces or areas painted and covered with varnishes on those occasions 49 00:06:34,980 --> 00:06:40,340 when a defect arises before making the decision to repaint the piece, the solution can be to 50 00:06:40,340 --> 00:06:47,460 eliminate it by means of fine sanding, polishing and polishing operations, this can be 51 00:06:47,460 --> 00:06:52,700 done both in small and large areas and preferably with well-treated paint, 52 00:06:52,700 --> 00:06:57,960 always carrying out the correct process and with the right products for each case 53 00:06:59,100 --> 00:07:29,080 We'll be right back. 54 00:07:29,100 --> 00:07:46,060 We'll see you next time.
