TotalBoat Glass Microballoons make for a great low-cost, low-density filler. They are white, hollow, and made of sodium borosilicate. To prevent sagging, Silica Thickener may also be combined with the microballoons.
To prepare for use, start by thoroughly mixing your resin/hardener. Then add in TotalBoat Glass Microballoons and your bulking agent. Blend well. TotalBoat Silica Thickener may then be added if applicable. ALWAYS remember to stir from the bottom to the top.

Can the cured microballoons be painted right over, w/o resin coating, as is specified on the MAS microballoon page?
Yes, once cured washed with water in case there is an amine blush on the surface, you can sand smooth, prime and paint.

I used it for a small underwater leak around a fitting.
It works really well
Good price, worked well
Worked good, a bit hard to mix, adding epoxy on top of the product helps, mix from bottom.
