momokote variability?


I've just used some maroon monokote I bought from a LHS. This stuff was terrible to cover with, it does not shrink nearly as much as other colors I've used ( red, white, black ). Is this common? Do different colors shrink at varying amounts? Did I get an old roll? Very frustrating.

sigh, so frustrated I guess that I mistyped the thread header... erg.

Monokote has gone through some changes over the years. Stuff I used 10 years ago was absolute crap. These days it's not too bad keeping some things in mind. Order it straight from Tower to get fresh rolls. It needs to have that chemical smell to it. Don't expect it to shrink much and get the wood completely dust free before application, it does not stick as well as it used to.

I haven't done it but it makes sense to me.... Some are using a normal prep including removing all the sanding dust. Then either spray with hairspray or very thin lacquer is sprayed on. Another light sanding and dust removal before covering. This supposedly gives a slightly better surface for the Monokote to bond to. You could also use Balsarite as an adhesion promoter. Balsarite only needs to be applied to those areas you want/need the Monokote to bond to.

I do not know this for sure, but I suspect that it the ability to shrink has to do with the quality of the batch that is manufactured and not the color. The quality control where it is manufactures is probably not very consistent. I have purchased a color of monokote that worked shrank well when applied. I then purchased the same color a little later for a different build and it hardly shrank at all.

I agree with several of the above posts: It's mostly a quality-control problem, not a problem with particular colors, and it's better now (unless you get an old roll). It seems to be true that they changed the formula a while back, but the only difference I see is that it doesn't shrink as much, which isn't really a prolbem if you're careful.
