surface adhesion problem with glaze

_strider | Posted in Finishing on November 3, 2004 12:42pm

ok, here’s the lowdown on what i’ve done before i get to the problem
all products m.l. campbell

1 coat clawlock
sand 220
2nd coat clawlock
sand 320
1 coat tinted resistant
sand 320

My topcoats, after glazing are just peeling up with light pressure applied to the end of a fingernail.

ok on my test pieces i gave the client a light glaze and they approved that… but of course after they saw it on some cabinets they changed their minds and wanted a heavier glaze… so i said ok. now i am having some serious adhesion problems. this is what i have tried to no avail to solve this situation.

combo1: vinyl sealer, glaze, vinyl sealer, top coat with magnalac

combo2: vinyl sealer, glaze, vinyl sealer, topcoat with krystal

combo3: glaze, 2 topcoats magnalac

combo4: glaze, 2 topcoats krystal

combos 3 and 4 have given me almost liveable results but these cabinets are goin in a kitchen and i know i will be gettin a call back on this

please anyone with some experience using heavy m.l. cambpell glaze give me a hand. I will be on here to answer any questions that might shed some more light on the subject.

Thanks in advance,

Lee

Lee,

If you allowed the finish to cure long enough before testing the adhesion then it sounds like the glaze is too thick. Applying the glaze in two coats with a seal coat between them is a work around to the problem as long as you don't exceed maximum dry film thickness.

What effect are you going for with the glaze? Are you using WoodSong or Amazing Glaze? Have a picture?

thanks for the quick reply,

i am using woodsong no vinyl glaze but i have gone as far as to try samples using the procedures layed out by m.l campbell for the regular woodsong glaze. (no vinyl glaze is just the regular glaze thinned with mineral spirits, apparently)

i have allowed 48 hours for some of the glaze samples to dry with the same problem. the glaze is thick. it has a brush stroke look to it and where the glaze is heavy is where the problem is. i talked to the m.l. campbell reps and they say that it cannot be done without adhesion problems and that all of their glazes will cause poor adhesion. one rep even told me that all of their glazes under any top coat will fail a grid adhesion test......

i see factory finishes with heavy glaze, brush strokes, how can i achieve that look with durability? or can i? thanks again for the help.

Wiped off just to highlight the grain, I've let the WoodSong glaze cure for a week before topcoating and still had problems in the corners where there was a little excess. Try the Chemcraft or Valspar glazes; they have a tougher binder. Chemcraft works with all topcoats and Valspar has a glaze for post-cat topcoats.

Let the glaze flash off (dull) and then lock it in with a coat of sealer. Use a catalyzed sealer if you use the CV topcoat.

Just my opinion, but I like the finishes from Chemcraft better than Campbell. I do like a few of the WoodSong stains that Campbell has as well as the amazing glaze (check this link for typical use - http://www.furniturefinishwizard.com/sprayglaze.htm ).
