\"AwlgipFirst Identify the paint that is there. Is it compatible?<\/p>\n

If yes \u2013 Sand, Primer, Paint<\/p>\n

If no \u2013 the previous coating needs to be taken down. Sand with 80 grit paper until the coating is gone. Sand blasting is not recommended because it takes away the aluminum itself.<\/p>\n

How do you know if previous paint is compatible with Awlgrip? Perform this test:<\/p>\n

    \n
  1. Need a rag and some Lacquer thinner<\/li>\n
  2. Sand the surface with 80 grit sand paper<\/li>\n
  3. Apply lacquer thinner to the rag and hold it on the sanded area.<\/li>\n
  4. Put a piece of plastic on to to hold the rag so the Lacquer thinner doesn\u2019t evaporate.<\/li>\n
  5. Hold rag for 35-45 min.<\/li>\n
  6. Remove rag slowly. Is surface bubbling or lifting? If no, scrape surface with the blade of a knife. If the paint comes off with the blade or the paint feels rubbery you have identified an acrylic based paint. Awlgrip may be applied on top of it. If the surface was bubbling or lifting, the paint is not compatible and must be removed.<\/li>\n<\/ol>\n

    \"D6600II.\u00a0Apply Awl-Wash Primer CF (Mix Part A<\/a> and Part B<\/a>) within 4 hours of cleaning the surface. This provides excellent adhesion to the aluminum surface. Awl-Wash CF can be overcoated with primers after 1 hour of application. Maximum recoat time without sanding is 6 months.<\/p>\n

    III. Apply a Primer to the Awl-Wash Primer CF. There are 2 main choices.<\/p>\n

      \n
    1. 545 Epoxy Primer<\/a> \u2013 Thin, building primer. Usually applied when there is no need to fill scrapes or gouges.<\/li>\n
    2. Awlquick \u2013 a medium build, primer\/surfacer. Applied to a surface that needs to be filled where there are scrapes or gouges. Awlquick Base<\/a> + Converter<\/a>.<\/li>\n<\/ol>\n

      IV. \u00a0Apply a topcoat.<\/p>\n

        \n
      1. Awlgrip<\/a> \u2013 may be brush rolled or sprayed \u2013 usually lasts 7-10 years.<\/li>\n
      2. Awlcraft<\/a> \u2013 must be sprayed only \u2013 usually lasts 4-6 years.<\/li>\n<\/ol>\n
