TotalBoat Silica Thickener is an extremely fine powder used to create a smooth, non-sagging, high-strength mixture for structural bonding, filleting, and filling. It can be used alone or in conjunction with Milled Glass Fibers or Phenolic or Glass Microballoons.
To prepare, first mix together the amount of resin/hardener that your project requires. Then add any fiber fillers or bulking agents and mix well. Add silica thickener to the mixture last. Remember to ALWAYS stir bottom to top.

This product worked as expected. It is very light and tends to blow around if there is any wind when it is mixed.

Thickener to make it stick
Added in sufficient amounts to thicken the TotalBoat epoxy so it would stay put against the underside of the deck long enough to insert the G10 reinforcement into the repair opening. Blended well once enough was added to get the right consistency.
