Hi. We have been working with a bullnose in a terrazzo step. In order to get the curvature of the bullnose correct with less grinding, we have been experimenting with creating a mould. We successfully created a mould from the bullnose made of plaster reinforced with burlap. We then sprayed the mould with silicone and then filled with a combination of stones and terroxy. Unfortunately the terroxy attached to the plaster and is almost impossible to get off. I didn&#39;t think it would be so hard to remove. Wondering what material I can use between the plaster and terroxy that would create an easy separation. <div>On another note, I mixed the terroxy as prescribed (5-1) and added the aggregate but some of it came out gummy. Maybe not enough mixing? Although I thought we mixed it pretty well. I have had this happen sporadically before. Any thoughts on the above?  Much appreciate it. </div><div>Baird</div><br><br>-- <br><div dir="ltr"><br>________________________________________<br>From the desk of<br>Baird Standish<br>Managing Partner<br>Facility Specialists, LLC<br>15 West Highland Ave.<br>Suite E<br>Philadelphia, PA 19118<br>Phone: 215-732-7505<br>Fax: 215-546-9160<br><a target="_top" href="http://www.facspecs.com" target="_blank">www.facspecs.com</a><br></div><br>
