Krystal over resistant ?

I've tried Krystal over resistant with better results than 2 coats of resistant. Has anyone else used clear over pigmented finish? How did it turn out? Any advise would be great.

We often put a clear coat over our pigmented cv. Adds depth and makes touchups easier.

Dan - what problems are you having with the Resistant? It may be possible to work out the problems and avoid the additional labor and materials of applying another coat.

Hi Dan,

I've been using MLC Resistant Pigmented top coating for long time now and have been having more and more mixed results with the finish quality. Regardless of my in shop temp and humidity I'm routinely adding a little Care Retarder C161. Starting this year I'll likely change more product to MLC Stealth Post-Cat. Suggest you try the C1621 Care Reducer along with the standard C16036 reducer.
My neighbor routinely clear coats over her pigmented coatings but its got a look thats to my liking. When I get a good result with the MLC Resistant its very good.

Sounds like Richard is having the same problems.

I was faced with the same situation before. I tried a number of things to get the finish to work well including various thinners in various ratios as well as changes to the spray equipment and spray technique. In the end, I had to switch to a different product to get the results I wanted and was very happy with the results.

Maybe someone here has overcome the problems you're seeing and can offer some advice. If not, consider testing some other products. Anytime you add steps or additional products to your finishes you are cutting into your profits (unless you adjust your pricing).

Richard. I used the reducer and it helped and thinned it more. I usually only use the retarder when it extremely hot out.

I gave up on Resistant and switched over to Stealth. Took a while to figure out how to get it to work consistently.

Use a mixture of Reducer and Flow Enhancer #2. I usually make a 50oz mixture of the concoction, 20oz #2 and 30oz Reducer.

I'll mix up 20oz of Stealth and put 4oz of the mixture in it (20%). In the Kremlin I use 35psi liquid and 17psi air (trigger pulled).

As for putting Krystal over Resistant, why not. Only thing is Krystal will impart a very slight green hue to a white.

As Leo said, there can be a slight color change on light colors esp. I found out the hard way. If you're matching something closely, do some samples to check.

if we intend to clear over the pigmented, we do so in the sample submittal stage. That way the customer has reviewed and signed off on the final appearance.

But as both above posters have mentioned, clear definitely changes the color and look.

A typical scenario where i find it beneficial to topcoat over pigmented is on the high gloss. You get a much more brilliant gloss when you apply a clear over the pigmented.

Ya know I just asked my MLC rep that the other day , because we are spraying some really dark resistant , but my rep said Krystal over resistant would do no good . Though we have done it with some of there pre-cats.

I'm sure Leo's reduction flows out really well, but I always experiment in how fast I can get it to cure with an acceptable appearance, and with Stealth I am consistently reducing 20% with acetone and getting great results.

I struggled with Resistant years ago, especially dark colors. Orange peal city. I even gave up on black all together opting for an extra coat of Clawlock with a clear coat.

  • 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.

  • 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.

    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.
