Email Q&A: Need Silica Sand?
Question:Hi! I made several holds but they seem to be weak, some of them broke. Besides, their surface is glossy, shiny, even though they have a nice texture. I wanted to know if the silica sand is the missing ingredient. I think that would make them stronger and improve the texture. Is that right? Im using poliester resin (the only one I can get here, in Argentina, but is almost the same you use) and plain sand… Your page is really useful!!! Thank you very much… Jessica Answer: Jessica,it does help to have silica sand because the smaller size grain adds a better media to support the resin. Another suggestion for you is to get some sawdust and mix a little of that in. I’d suggest trying about half support media and half resin/harnder mix. Of the support media, make about a fifth of it sawdust and the rest play sand (or silica if you can get it!). If your holds are not flexing and are too brittle, add less hardner and give it more time to cure. For an extremely realistic texture on
