Mixing MLC Resistant and Krystal

10/26/21       
Geoff

I need to repaint a few cabinet door fronts and have just a little bit of resistant left. I have almost enough to make it but want to stretch it just a bit if I can. Is it possible to cut it with some Krystal or something else to make it go a little further so I do not have to buy another gallon?

Thanks

I wouldn't.

No!!!!! These are 2very different animals, 2 different resin systems. You have no choice at all but to ante up for like with like, i.e., shell out the shrinking kings for another gallon. If you add 20% or even 25% reducer, you can do that, unless you have a finish that's too translucent to be useful as a pigmented topcoat. But you better have nothing more coarse than an 800 grit scratch/scuff pattern or else you'll be looking at your sand scratches telegraphing into your topcoat.

What is your topcoat?

Geoff,

Ask your area's tech rep. If He/she does not know for sure, ask the rep to contact a Cambell chemist with your interesting question. Both products, I believe, use the same catalyst, same % of catalyst and reducers.

Read my answer above. It's definitive. You can spray on product over the other cured product, Resisrant over Krystal or Krystal over Resistant. You cannot mix the two liquids together and end up with a decent topcoat. What will happen if you do mix them? You may end up with a topcoat that curdles. You may end up with a topcoat that doesn't level nicely. You may end up with a topcoat that lacks the durability and/or the performance that you sold to your customer. Or combinations of those maladies, or something unseen amd unpredictable. What you won't end up with is a solution to your problem. Buy more Resistant or add in more lacquer thinner to what you catalyze on hand. Period.

Geoff,

Still doesn't hurt to ask and receive a Cambell chemist's definitive response.

We know the answer. The chemist isn't even going to try to figure it out. He's going to say buy another gallon.

Well Leo G, I can't say I disagree re getting another gallon; yet I suspect the sales rep would say that whereas the chemist may well know, if not off the top of his/her head, pdq. And I would wager he/she would be inclined to speak the facts at any rate.

And, I am sure, a new batch of paint will exactly match the old. Not holding my breath on that one. Not knowing the client let alone where the fronts fit in the scheme of things...

All that being said, I would still ask a professional - i.e. a Cambell chemist. Knowledge is a wonderful thing, and one can't know until one asks as me mum often said. In fact I think I will.

Geoff,

Oh boy, just had another thought.

Get a gallon of resistant neutral. Good to have around anyway. As I recall, Cambell has one for resistant and turino as well. If your rep is well stocked, they should have it; I wouldn't add more than 10% - 15% at most anyway.

then call the chemist!

Resistant, Turino, and Stealth are available in both pigmented and also clear stain bases. Without any colorant added, the gallon cans are shorted so that you have room to add in pigmented or dye colorants.

The pigmented bases are used to make whites, pastels, and light colors. Dark or bold colors go into the clear base.

Why use a clear base instead of Krystal? Krystal will tolerate up to 6% of the IC800 series colorant, as will the clear bases.Holding the added colorant in suspension, the clear bases do a better job of this than will Krystal.

These three catalyzed varnish systems each have their own resin systems. You can't pour one into the other. Resistant

Years ago I did this sort of thing, using Stealth and "KlearVar". I was running out of the pigmented but needed 1 more coat on maybe 3 items, so I mixed it and it turned out fine, since both products were the same sheen and the same catalyst and catalyst ratios.

YOUR mileage may vary. I tried this once with Sherwin Williams stuff (clear and paint, same catalyst but different catalyst ratios) and the final product looked like Rustoleum Hammered look, so I don't do that with that particular SW product.

Geoff, et. al.,

Well I did it.
And the response from the Cambell Chemist: One can add krystal to turino as well as resistant with the following caveats:
1) adding too great a percentage of clear to the paint may create a color shift ( I say anything over 15% mixed into undiluted base paint may be pushing it)
2) adding too great a percentage of appropriate neutral... same potentially negative result.
3) add appropriate thinner, again mind the percentage!
4) buy enough paint to begin with!!
And then he laughed. Thought he was funny.
Of course he's right. And shit happens. So it's good to have a wee bit more knowledge, I say.
Cheers and may all your projects be as smooth as silk.

Well if paint was $30/gal that wouldn't be an issue. But at $60-$120/gal you start to try to not have extra around at the end of the job.

Polarion plus the catalyst is pushing $120/gal these days.

The MLC tech support has always been excellent. I respect people when the tell you the truth that you can do something even when you should not. At the very least, they give you the permission to ruin your work at your own behest.

Yeah Leo,
That's why so many of us have the need to stretch pigmented product with thinner, neutral, and/or clear. Scrambling to stretch product got old at least 30 years ago. I would rather have a limited stock of paint kicking around to use as base for a one off job, such as a vanity, and add colorants to "match" provided sample. Also, if the cost of a gallon is gonna mean winner v loser for a job, maybe you need to review your pricing evaluations

And Adam, I just don't seem to understand to what you are referencing - there are oodles of ways to ruin a project. Not as many to save a project me thinks.

I stand corrected with regard to mixing one finish with another. That said don't add anything to Stealth other than Care Catalyst and Care Reducer. Stealth doesn't tolerate our attempts at alchemy.

Chemistry Daniel, not alchemy silly boy.

It's alchemy. None of us are chemical engineers, silly or not.

    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).
