Фарбування пластикових деталей автомобіля своїми руками
Щоб якісно провести фарбування пластмасових деталей автомобільного салону, потрібно дотримуватися певного алгоритму дій, і перш за все, правильно виконати підготовку поверхні під фарбування. This is necessary:
- Зняти деталь і, перш ніж знежирити, ретельно промити її, оглянувши на наявність тріщин і інших дефектів.
- За допомогою розчинника або уайт-спіриту прибрати жирні і масляні плями, а також інші забруднення.
- Обробити поверхню антистатиком, щоб статичну електрику не притягають пил.
- Якщо є дефекти, потрібно усунути їх спеціальної шпаклівкою для пластмаси, і дати поверхні час на просушку.
- Затерти всі нерівності наждачним папером. При цьому шліфувати потрібно «по мокрому», застосовуючи абразив Р300 або Р400.
- Rinse, ретельно висушити і знову знежирити виріб.

- Нанести тонкий шар адгезійного ґрунту і 1-2 шари акрилової грунтовки з інтервалом 10-15 хвилин на висихання кожного шару. При бажанні отримати структурну поверхню, в останньому шарі використовується текстурная грунтовка.
- Після висихання грунту зачистити ґрунтовку абразивної шкіркою Р400-Р500.
Поверхня повністю готова до фарбування. At home, якщо немає фарбопульта, можна скористатися балончиком з фарбою у вигляді аерозолі або звичайної пензликом. Фарбу наносять в 2-3 шари з інтервалом 15-25 minutes, і дають деталі добре просохнути. Тільки після цього можна покрити поверхню лаком і відполірувати спеціальною пастою.
