Primary bonding vs. secondary bonding
2 Replies

Hello boatbuilders,I am going to coat the interior of the hull panels of my Melanesia. Do you recommend using the wet on wet technique (when the previous coat is sticky, apply the next one)? That way…Continue

What is the best way to get rid of the dust after sanding wood and before coating?
7 Replies

Hi!Just brushing the surface doesn't seem to get the fine dust out. I was going to use a rag with alcohol or thinner. I just read, however, in the Gougeon's book, "we do not recommend using rags for…Continue

"Didn't know that.... In the shop they recommended the tack cloth... I'll be careful about it"

Omar M. Rashash replied to Christian Linder's discussion What is the best way to get rid of the dust after sanding wood and before coating?
"A tack cloth can be a really bad idea when working with epoxy. Whatever it is impregnated with may interfere with the ability of the epoxy to cure. If you're going to wipe it down, either use a wet cloth or a cloth saturated with acetone or…"

"Ok, thanks for the tips! I also found in the shop a tack cloth which is pretty efficient."

"I use, brush, and after use rag with a little alcool, works ok, no problem. Don't aply solvents. "

"I used a shop vac with brush attachment after using the exhaust function to blow all the dust out first. "

"In the instructions manual they recommend allowing to cure the first coat. However, the West Systems video tutorials on Youtube say that you can coat wet on tacky (without sanding) and the Gougeon Book does as well. I am going to try the wet on…"

"Thanks Budget Boater,  I don't have the compressed air... all the other steps I'm going to follow!"

"If you are using West System, follow their recommendations. We use a non-blushing epoxy and coat wet over tacky."

"Brush, followed by compressed air, followed by clean water using lint free rags."

Robert Hughes replied to Christian Linder's discussion Sticky Epoxy
"That sounds like epoxy that's not fully cured, rather than amine blush.  Amine usually washes off fairly easily, rather like a very thin coat of honey would.  Whatever it is you do need to get back to a hard surface.  The…"

Christian Linder replied to Christian Linder's discussion Sticky Epoxy
"Another interesting point: I used the same mix of resin and hardener, after coating, to glue some parts by thickening it with microfibres. Now, the epoxy that was mixed with microfibres got rock hard... of course it was not applyed as a fine coat…"

"Hi guys! I think I didn't get the ratio right because I mixed by volume although it was by weight. However, I just checked, doing the mix by volume again and weighting it and it's pretty much the same amount by volume as by…"

Edward Wolfe replied to Christian Linder's discussion Sticky Epoxy
"Be aware also that some epoxy ratios are by volume and some by weight. I use Raka (USA FL company)for one reason because it's 2:1 by volume and very easy to get the mix correct. I doubt if I've ever been within 1%, but never have had to…"

Robert Hughes replied to Christian Linder's discussion Sticky Epoxy
"It's possible that your epoxy has set ok, and the stickyness is actually amine blush.  This can form with many types of epoxy, where the surface is exposed to the air as it sets. If it is amine blush it should wash off easily with warm…"

Allen Bosely replied to Christian Linder's discussion Sticky Epoxy
"I'm not expert here, but from what I've read, you need to scrape all the unhardened epoxy off, wash it down with white vinegar to remove all the unhardened epoxy residue then reapply new epoxy. Also, don't forget you need to coat all…"
