Well I had the boards in a 90 degree room for about 4 days and it’s definitely better but such an absolute pain to sand that I have given up sand these boards past the 150 grit. I’m just going to put one of those finishes people have suggested before. The behr deck sealer that people have suggested most likely. I’m not positive what it was called, I’ll have to search the archives but these things just will not sand without immediately clogging the paper. It’s like I’m sanding a poly lamination.
Clean your board with water + soap and a scotch brit, may be your resin blush while curing only way to eliminate it is water cleaning. Water sand it with, start120 grit if you can then go to dry papier, if it still clog there was a problem with your mix, to much hardener let resin gummy.
Mix by weight, not volume. Less mixing error, more precise.
It was mixed with a scale. I did 8oz of epoxy on top and 8oz on the bottom. I don’t think the mixing ratios were an issue. On the hot coat I had added the accelerator and sanding it was not an issue. Didn’t use the accelerator on the gloss coat.
Next time you glass with epoxy make sure your work area is at minimum 70 degrees and stays that way until the board is fully cured. I wouldn’t subject a freshly epoxy glassed board to temps in the 40s or 50s for at least several days.
Years ago when I was working with epoxy I glassed a board that I was particularly proud of. A day after finishing sanding and polishing a friend stopped by and I brought the board outside to show him. The temperature was near freezing. Within moments the surface of the board took on a milky appearance from the reaction to the cold and changed feel to the touch. It was as if the resin was sweating or something. Lesson learned. I did one more epoxy board after that and switched back over to poly resin.
Yeah I’m just done trying to get this to look any better. It’s decent right now and is smooth to the touch. Just doesn’t have a finished looked to it. Anyone think it would be fine to do a behr low luster after only 150 grit? Or should I wet sand by hand 220-320-400?
Lots of ways to do this as shown above. My preference is to sand to 180 ish and then wipe on Behr cement sealer. You can get it in gloss but never tried that. If you do go with gloss, wipe the board with a strip of tape to get every little bit of dust off (after you have washed it with soap and water). You can do this. Good luck.
Make sure to post cure.
Just to avoid more experimentation and get this thing in the water I’m just going with the low luster. No need for a gloss finish at this point. I’ll try that on a board thats cured properly. Thanks.
Do you mean for future boards or were you saying also to post cure the behr sealer?
After this issue I plan to build a cure box. Just have to figure out my design/ board capacity wanted.
