**Test data shown are based on averages subject to normal variation on individual tests, and therefore should not be assumed to be maximum or minimum specifications.
***Application by alternative method may produce somewhat different results.
Measures are approximate and may vary. For mixing partial units, contact Stellar Materials for specific wet-to-dry ratios. See Installation Guide for more detailed information.
To assure you are getting the latest data, see our online data sheets at tds.thermbond.com.
Due to the unique nature of the Stellar binder system, test procedures vary slightly from ASTM.
