In Response To: Epoxy: how to prevent sagging (Michael)

: HELP please:

: I am assembling a clc cradle kit and following the directions for
: sealing the hull I got nice sags decorating the hull. Yuck.

: I tried using a brush as the epoxy cured to prevent sagging. I
: think it sagged after the surface was hard enough not to respond
: to the brush.

: I'm certain I applied it too thick. But how do you prevent this? I
: tried using a squegee, credit card, on a flat surface and it
: seemed to turn the epoxy milky. Was this fine dust or something
: else?

: The hull finish will be paint, but the blemishes will show thru
: this. I am inclined to use 80 grit in the jitterbug and get
: aggressive with the surface. I am also inclined to let it go and
: just accept the surface 'irregularities'. 'Cause eliminating
: them might exhaust my time budget. I want a good looking job,
: but I'm not after the 30 hand-rubbed coats effect.

: I am tempted to just paint the interior and skip the epoxy steps.
: After all, it's an indoor piece of furniture.

: So I have two problems.

: 1. How to make the most effective and least time consuming exterior
: adjustments for an acceptable finish.

: 2. How to prevent the same problem on the inside.

: Thanks in advance for whatever info you might have.

: Michael

Hi Michael,
Use a carbide scraper instead of sandpaper, less dust and easier to control how much you take off.

I only once got a milky look applying epoxy, I was using a card/squegee as well but the milkiness disappeared after a short while. I think it was moisture that was my problem rather than dust. Micro air bubbles could be another cause, maybe. Moving the card quickly might bring in those bubbles.
