No advantage, it was just an experiment that worked well. Honestly I just forgot about the tube.

Wrinkles are a problem whenever you use carbon. It's always stiff on the bias. I have only used the multi-layer method on simple forms.

I was watching some guys glass with epoxy last weekend at Sacred Craft/Boardroom and they were cutting the wet cloth with scissors. I should have watched what they did with the scissors after but assume they dumped them in a container of acetone.


Then clean up easy with a rag and orange goop. Forget the acetone.

Magenta, I know those guys from e-tech. I'll reach out but like DW says no acetone.

It's not been covered here a lot but acetone can cause the sensitivity to epoxy that people warn about. Denatured alcohol or as DW says (better) orange cleaner will lower the chance of skin reactions.

That's great to know that Orange Goop works for cleaning hands and tools! Have you tried vinegar?

Is there a better way than using acetone to clean brushes so you can reuse them?

For ding repair I clean brushes with denatured alcohol and get a few uses.

New brushes only for epoxy hot coats!

I'm conflicted as to the impact of cleaning chemicals vs tossing the wood chip brushes. for poly resin and acetone there's no comparison, it's cleaner to toss. board building is far from eco friendly no matter how you slice it.

I buy cheap disposable brushes and toss them when I done. The bristles start falling out of them during the first use, and I end up having to back track and pull them out of my hot coat. That pisses me off. I develop a short term hatred towards that stupid brush, and take joy in seeing it's end of service into the trash can >:(
I wear disposable gloves too, so the clean-up is pretty much cleanser and or solvent free.

Try these from Home Depot. Fantastic. Worth the extra cost. You can cut in half and do 2 hotcoats with one pad.

DW - I saw those pads at Home Depot yesterday. Besides not having to deal with loose brush bristles, what other advantages are there for using them? Can you totally omit the use of a brush for doing hot coats with those pads...even around the rails?

BTW, does anyone know where I can locate DW's video that shows him using the wet out table? I did a search and found nothing.

The wet out table is easy. I use a 4x8 sheet of 1/2" plywood laying on a saw horses near my board. I cover it with a sheet of thin plastic that I staple to the under side of the plywood. You put a layer of plastic, then the length of fabric over it. Then another layer of plastic stapled under, and a length of fabric. Repeat for each layer. Mix your epoxy and spread it evenly over the top layer of fabric. Use your squeegee to spread it till the entire length of fabric is wet. You can collect the excess back into your mixing bucket for the next layer. Then roll the top layer of fabric up  on to a piece of pipe. I use a 3" by about 42" long piece of white yard drain pipe. I cut a 2 lengths out of a 10' pipe. Use the second piece of pipe for the next layer.
Take the rolled fabric and line it up so it rolls out straight on to your board. Just roll it out a couple of feet at a time, so you keep it straight. Squeegee it down as you go. Clock is ticking, you got 20 minutes give or take depending on conditions. (BTW, you'll have a lot of epoxy left on the plastic. That's saved weight right there:) )
Get it rolled out, pull the plastic off the wet out table to expose the next layer of fabric. Wet it out, roll it up with the other clean pipe, and get it on to your board. This is how I do it. There are variations on layering. Just stay committed, you have enough time. Don't drag your feet, or you'll have a mess.

Ran across a great deal on brushes at Ace Harware of all places...they have a bin of inexpensive brushes for $1.29 each...and I'm not talking about those cheap typical throwaway brushes...these are more like full body paint brushes. I bought 20 of the 3". I haven't used them yet but these look like they would shed a lot less than the typical throw away. As long as they continue to sell at that price they are going to be my new "throw always". Love it when a store has a "loss leader" that I can actually use.

On another note for loose bristles you can always run a small line of catalyzed resin (let it cure) the day before using them...tight to the heel of the brush to help bond bristels from falling out as easily.

Thanks for the great explanation! Two questions please.

1) How do you deal with cloth that's over 8' long? Use a 10' sheet of plywood?

2) Would you do the deckpatch at the same time too?

1. I just fold the extra back over itself and wet it folded. When you roll it on to the pipe and unfold it as you roll it on.

2. I'd say maybe do it separate seeing it's your first time. You'd have to move pretty efficiently to do a third layer at the same time, unless you have help. I'll try to post a video I did a few years ago. I'll have to do a little editing first.

When I have pre-wet cloth I do it on a shorter piece of plastic.  Use a piece maybe 3 feet long.  Wet out the 3 feet (or a bit less to avoid the edge), roll it onto the pipe, then pull the next section onto the plastic sheet and wet it out and keep going.  Less epoxy wasted on the plastic, and when the cloth gets put over top of wet plastic it starts to wet out from the bottom too so it wets out nice and fast.  The only issue I can think of is if you had warm temperatures and wanted to get the resin out of the pot and spread out as fast as possible, keeping the resin in the pot for longer rather than dumping it all at once could be an issue if things start to heat up and cure fast.  I suppose dumping all the resin and squeeging over long strokes might be a bit faster, but the rolling time and unrolling time and working time on the board is all the same.

edit:  I should add, to answer an earlier question, that fully and perfectly wetting out the cloth is usually not an issue if you roll it up after.  It is in contact with wet stuff on both sides when rolled.  Don't get too sloppy, but don't obsess about the perfect amount on the entire sheet of cloth, because it gets averaged out once it is on the roll.

I use the slow stuff when I'm doing wet out on a table. Drives me nuts, but I don't have to race. I also pour the epoxy into a shallow pan to keep the catalytic heat from kicking the pot prematurely.

I'll add that for cloth longer than 8' I fold the excess under. That way when wetting out I don't start getting strings as I'm pulling the resin around. And I use the fast set epoxy without problems.
