Rated 5 out of 5 by 2 reviewers.
Rated 5 out of 5 by Use with custom mortar thinset 50lbs gray. Created a much more solid bond than using just plain mortar. Don't be cheap, buy both parts. November 12, 2014
Rated 5 out of 5 by Great additive I am a mosaic artst and using this additive in my slurry mix really makes the grade. It makes your final project more resistant to water and let likely to damage when bumped or moved. Also seems to hold up through time and bad elements. I live in a high wind and cold climate in the winters and all I do is cover my projects with plastic tto avoid high blowing sand in spring. I would recommend it to anyone in this artistic area or anyone who does concrete sculpture as a top coat additive. March 5, 2009
