If the mastic is thick enough and it is gooey, you can freeze it with carbon dioxide and it will make it brittle and it will scrape right up.    <br><br><div class="gmail_quote">On Fri, Oct 5, 2012 at 8:47 AM, Georgia <span dir="ltr">&lt;<a target="_top" href="mailto:georgia@stonebuff.com" target="_blank">georgia@stonebuff.com</a>&gt;</span> wrote:<br>

Client removed old cork flooring. Mastic was left. I had the concrete and mastic tested for asbestos and it is negative. We need to remove this mastic. We dry ground with 50&#39;s but it was barely cutting it.  So we grabbed some mastic stripper and saw it was helping a bit.  It ended up spreading all over and making a more sticky mess.  Does anybody have any tips on how I can remove this 50 year old mastic?<br clear="all">
