Microballoons ?
I need to fair large deck surfaces in prep for paint. The repair thus far
has been all polyester, can I use microballons to create a polyester fairing compound? John |
It's highly recommended to follow the paint manufactures recommendation for
fairing. Depending on the density of the Microballons they may be too soft to sustain long time use, causing cracks. Dave "John Cassara" wrote in message ...

Welcome to the world of 'fillers'.
See: http://www.fiberglasssupply.com/Prod...s/fillers.html for a pretty good basic introduction. MW Los Angeles |
Gee, I can't guess where i might find them at lower cost and with the
specific gravity data I so desperately need. Anybody got an idea? "Paul Oman" wrote in message ... wrote: Welcome to the world of 'fillers'.

MW Los Angeles ---------- wow! they are expensive at that site and they don't even tell you the specific gravity of the microspheres (yes, microspheres come in different sizes).

A quart is not going to go very far when refairing a deck. Fiberglass Supply sell a pound which is a a little more than a gallon of 3M K-15 microballoons for $10.58. As far as specific gravity goes, yours is the only site that touts it. OK, so yours is .5. That is more than a bit on the heavy side. 3M Scotchlite bubbles comes in specific gravities from .125 to .6. Fiberglass Supply sells K-15 which has a specific gravity of .15 which makes a much lighter putty. The crush strength of the bare balloons is 300 PSI which is plenty for deck repair when mixed in a resin putty. For a rundown on the 3M Scotchlite product line see: (you may have to cut and paste the link)http://products3.3m.com/catalog/us/e...dustry/paint_c oatings/node_SQ4MWCTNSLge/root_GST1T4S9TCgv/vroot_Q0SJ3LJK63ge/theme_us_pain tcoatings_3_0/command_AbcPageHandler/output_html As for me I will stick with the brands that I know like 3M and Q-cell depending on the application and buy in quantities that make sense. After all microballoons don't go bad on the shelf as long as you keep them dry and bake out pretty well if they do. Fiberglass Supply always has the best prices for less than full roll fabric but the best selection and prices I have found for fillers is usable quantities are from Fiberglass Coatings Inc. http://www.fgci.com/cgi-bin/dpsmart/...typ e_0207_01 -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

When you have a price at least 10% below my current supplier, $19 & change for a 30 lb bag, on my dock in Los Angeles, get back to me. Lew |
How about diatomaceous earth as a filler.
It is the skeletons made of silica of microscopic creatures from long ago. Has anyone tried this as a filler? I would think it would be good and cheap. "John Cassara" wrote in message ...

What for? Diatomaceous earth would make it heavy and harder to sand without
adding any real strength. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

Would it really not add strength, I would think the opposite.
Yes it would be tough to sand "Glenn Ashmore" wrote in message news:tX%Xd.60176$SF.48249@lakeread08... What for?
