I used a gray pigmented water based Lacquer to prime under white-based, pigmented white water based lacquer.
I'm using SW Kem Aqua.
I've used the product 6 times so far , always with a beautiful, opaque finish.
On this project, after 6 coats of white, I still have gray shadows.
I'm spraying with an Apollo hvlp rig that I really enjoy using.
And its only inside the cases. All the flatwork is opaque.
All the pieces are the same material.
Obviously, I've done, or am doing, something wrong.
I've used the product in the same way on previous jobs with great results.
None of the other projects were white top coats. They were darker colors.
I'd love to be schooled. Thank you for sharing your thoughts.
Use a white primer. They have a product called a WB surfacer. Use that and then one more coat of Kem Aqua.
Either your coats are very,very thin, you aren't getting a full coat or the lighting is playing tricks on you. 6 coats would either cover everything or nothing. Not sure how else you would get what you described.
Once again for clarity- you self primed with gray Kem Aqua and then you sprayed 6 coats of white Kem Aqua over that?
i use shellac-based primer under the kem-aqua pigmented. you should need no more than two coats of the KA to achieve a good finish. FWIW, i find that warming the finish and substrate helps a great deal with KA.
Thanks everyone for the posts.
I'm headed back to SW for more material and I'll ask about the surfacer product.
I used the gray because I had over bought it on a kitchen that was all gray (don't ask me, that's what they wanted.)
It worked great on a green TV wall and a blue bench....but it is sucking on a white bookcase.
And I'll never do it again.
And I've never gotten good coverage with one or two coats of pigmented lacquer - am I being to scared of drips and runs and spraying too light? Speaking of light, my booth has flourescent lighting, and there's like 6 different shadows everywhere.
Suboptimal when doing a reflective coating.
The Kem Aqua does hold well to vertical surfaces, but I feel like it's better to apply another coat than sand mistakes off.
My bad, and I'm moving forward.
To Denny G - I'm using the SW product because of the solid color.
I usually use either a general finishes product or Hydrocote resisthane for clear coating.
I'd love to find a product like the Hydrocote with 60 g/l of voc's that I can tint a solid color. People seem to want colors right now.
FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards(return to top)
WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
A valid email return address must be included with each message.
Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
Subject lines may be edited for length and clarity.
"Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.
Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).
Libel: Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.
Improper Decorum: Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).
Advertising: The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).
Repeated Forum Abuse:
Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.
There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
