I concur with Robin about pressing down into the waffle pattern
those ribs of comb drawn perpendicular to plastic frames or plastic
foundation.
The bees will clean up the honey and move the wax onto the walls of
the waffle pattern.
If the wax has exoskeletons coating the walls, imo it should go into
the wax melting operation.
Advice to paint extra wax onto plastic foundation is widely
distributed. The vendors and manufactures don't mention it because
they don't want to admit they don't put on enough wax.
"Generous" is mentioned, but what constitutes generous?
Here is one way to do it:
• Put an inch or two of water into a pot, and add a couple of pounds
of wax to the pot too. The water is a safety precaution!! Water
Boiling limits the max temperature.
• Turn the heat on LOW. You're aiming for the COVERED pot to go
from cold to a slow simmer in 30 minutes to an hour. Avoid violent
boiling.
• Dip one of those (disposable) quarter-inch thick by 2 inch wide
bristle trim paintbrush into the wax long enough to get the business
up to melting temperature of the wax.
• When the brush and wax are hot enough, use the brush to paint wax
onto the plastic waffle pattern; work the brush back and forth to
force the wax all the way into the divots.
You're aiming for half-filling to completely filling the waffle
pattern with wax which is mostly free of voids.
It sounds potentially messy but it doesn't have to be. Rest the
edge of the frame on the rim of the pot while doing the 'painting.'
The bees work the wax out of the divots into cell walls surrounding
each divot.
• when done coating foundation, put a cover on the pot, and let it
cool slowly. The wax will solidify and shrink back from the pot.
Easy to remove.
Look at the bottom of the puck. Sometimes solids suspended in the
wax settle into the space between the water and the wax.
Save the wax-loaded brush for next time.
Is the water tinted yellow or tan? The simmering extracted some of
the color and ionic compounds from the wax.
MAKE SURE YOU NEVER RUN OUT OF WATER IN THE BOTTOM OF THE POT. Same
for double-boiler heating method.
If you have a really tall pot (10 inches or more) you can arrange to
have the top of the molten wax layer 8-1/2 inches above the bottom
of the pot.
(the foundations are 17 inches wide.)
(an inch or so of wax on top of water works just fine. You don't
have to have a pot filled with molten wax.)
Once the bath is at or near boiling, you can dip the foundation briefly
into the bath. Wax will mostly fill the divots as you pull it out.
Wax will solidify onto the cold foundation, but it'll be too hot to
touch for a few minutes.
So Dip one end. Let the foundation cool for a few minutes, then dip
the other end.
(obviously you ONLY dip the foundation - Not the whole frame the
foundation is mounted in. i.e. pop the foundation out of the frame
before dipping it)
If the foundation gets to hot, it will warp. Don't dawdle.
This method doesn't have to be messy either. Wax doesn't generally
drip from the dipped foundation.
(To save time you can dip the ends of a foundation, and paint wax
onto the middle)
Estimating:
It takes about One ounce to an ounce-and-a-half of wax to coat ONE
side of a Medium foundation.
A pound of wax per medium 10 frame box is a little on the skimpy
side.
(a pound of wax is about 8 pounds of honey equivalent)
Visit Sal-Army or Good Will, and look there for pots you can
dedicate to wax processing.
Keep an eye open for a hot-plate too, so you can set up for dipping
on the patio. The process will probably attract interested bees.
If you method of honey harvesting honey on plastic foundations is
scrape-and-crush, you probably already realized you need to add
wax.
Fortunately the method harvests a lot of wax.
That's my 2¢
