![]() ![]() Avoiding excess clearcoatĪlways avoid excess clearcoat on the part, and try to apply it evenly. Note that when applying the clearcoat, a larger cloud of atomised product is produced than when applying colour, because more pressure is exercised. The spray gun must be regulated in such a way that the product flows in fan pattern, in order to generate thin, even and extended coats. The same data sheet will indicate the values required for a correct application. The spray gun must be set with a pressure and nozzle opening based on the technical data sheet of the clearcoat to be used. Take as a reference a range of 20✬ – 23✬, as ideal temperatures for applying the clearcoat. This is why it is advisable to acclimate the booth through the different means available (heaters, rays, etc.). Extreme room temperatures, whether very low or very high (as it can occur when painting a vehicle in summer), may lead to subsequent paint defects, such as blooming, popping or spraying, among others. In addition to controlling the product’s temperature, the room temperature will also have a direct influence on the finish results. However, this will vary depending on the type of clearcoat and the manufacturer’s indications. Under standard conditions, the clearcoat should always be at room temperature, around 20-25✬. ![]() Clearcoat temperature and application temperatureĬontrolling the clearcoat temperature before applying it, and also that of hardeners and solvents, is a differentiating factor. for every two parts of clearcoat add one part of hardener and between 0% and 5% of thinner (depending on the dilution requirements). To get the exact mixing ratio, use the precision weighing scale and other bodywork attachments such as regulated containers with different mixing ratios.Īn example of a mixing ratio would be 2:1 + 0%-5%, i.e. This should be part of the natural process of preparing the mixture, and it will increase the performance of the clearcoat in terms of drying time, product flow and final finish. This mixing ratio will always be indicated on the manufacturer’s technical data sheet, so always following the instructions is essential.
