<div>Densifier just makes makes concrete harder. (densifying silicate plus c hydroxide = more csh gel)<br><br></div>
<div>It&#39;s ok to do more. The more the better. It will reject the densifier when it&#39;s had enough.( just like a sealer).</div>

<div>not sure there is a way to test for a densifer without taken a core. However with that said you should be able to densify over it.

Looking at a terrazzo floor from the 1960s that has already been polished before, but is obviously now showing signs of wear and abuse, mainly in the traffic areas. It has a  nice sheen in some areas but not a lot of clarity.<br>
<br>So how does one test for pre-existing densifier? Is it bad to densify again?<br><br>Thanks in advance for the replies.<br><br>J<br><br>Sent from my BlackBerry® smartphone with Nextel Direct Connect<br><font color="#888888">--<br>
