I have now tried to use the SW conversion Varnish 3 times. Actually I have had other’s who tried it and all have had the same issue as I did. It has a re-coat window of unknown time length, meaning it will lift. Which looks like a curdled up prune and the finish separates from the surface. Their data sheets do not address this in any way , but It has never failed.We have tried to do 3 coats in one day , wait 24 hours between, 8 hours , and 48 hours, irrespective it will lift in spots. In all cases we have had to strip and use another finish

I now have 2 9’ x 6’ sections of a conference table we wil have to strip and start over, the guy has already stripped it 2 x times and tried to get it, he brought it to me to spray a final coat, it had set for over 48 hours, one coat and it lifted.

In My professional opinion, the product should be avoided .I will also state we had the SW rep out, and what we got was an amazing song and dance. They had no clue and offered no assistance.

Not a rant .. just a heads up .

What a pain having to strip off new finish by no falt of your own.Thanks for the heads-up Charles,if you can’t make it work it can’t be a good product.It’s ashamed a company like Sherwin Williams has a product out there like this.

Well they sure have my attention, same thing with Gemini, used to use their products all the time, no issue, but not any more, its the conversion varnishes . I suspect they have been reformulated due to VOC regs.

Wait . . . Charles, you’re supposed to post the fix when other people say that can’t get a finish to work.

I’m so confused.

Charles , YOUR confused, how you think I feel .. I have tried everything in the book, .......Wait, I wrote the book.

Seriously, the products have issues, avoid them, but again, its just the Conversion Varnishes, something has changed.

That’s weird, I used this product on a bar (approx. 3 years ago) and it was fine. Used 3 coats as directed.
Something must have changed. It’s not the first time products have changed.
Remember when Mar-Lak went to Mac-Laq? (nitrocellulose lacquer) I’m positive they changed it.
It never was the same.

Here’s some photos Charles sent me of what happen.

Here’s what it looked like after being shot with the 3rd coat

and 5 minutes later

Then then feathering it out for the repair

Now Charles gets to fix it by spending a day sanding it all off. This all came about trying to do someone a favor.
Charles is always helping folks out I doubt that will change. All this because SW makes a bad product and sells it knowing it has problems.

heres my deal, I can handle this, but finish manufactures need to be held accountable, and I damn sure will . Had enough , they reformulate products, then when they fail they tell you , especially the hobby folks who really dont know, “its your fault”.. That puts me in orbit.

I love to get one their reps in my shop or on the phone, its usually let me get a supervisor to help you,.... never seen one or talked to one. Go figure !

I think you have contamination somewhere, used it two weeks ago and no problems.

Mr. Neil is right about that. If that happened to me I’d figure it was a problem on my end, not the product!

Upinflames I’m sure Charles appreciates your input but in case you’re not aware Charles teaches woodworking and finishing and has many videos and has even written a couple books on finishing .

Im glad it worked for you I have 2——$150,000 .00 down draft spray booths , with 1 m BTU furnaces, I have medical approved air , contamination , I don’t think so. I have had no issues with any other finish. Again Im glad it worked for you . I have a 24×60 dedicated building that is just for finishing.

I couldn’t give a rats behind how many books, how expensive your equipment is or how big of a building you have “just for finishing”. I do this for a living, not a weekend wannabe, looking at the pictures that another had to post, two or three spots tells me contamination. It DOES NOT have to be in your equipment, low and behold, it could be in the wood…..but, since you two are the “experts” I’ll leave it to ya…..hope you figure out how to use the stuff.

I would venture to say he isn’t a weekend wanna be. Quick being a dick. Edit: someone gets butthurt easily.

up in flames take a chill ..

I have 3 different folks, me included, who have had the same result , the other 2 are also professionals,
I only mentioned my facility, to let you know , I cant possibility see any way of a contamination , especially in sporadic locations,.

the other 2 live 125 miles away and 75 miles away, so ya think we all have the same contamination, im sorry but , I have no issues with this problem other than the SW and Gemini conversion varnish.

if it works for you , by all means continue. . Just saying

Oh yea . Google the issue, Im not the only one having the issue, . Just saying .
