Although you can never rule out 100%, seldom is the curing the result of defective product yet it is first to be blamed when something goes wrong. Most of the time it is the result of the conditions at the time of application and/or the mixing of the material. Too often, the data sheet is consulted after the problem exists.
The conditions that effect cure are as follows but are not limited to:
- Air and surface temperatures
- Moisture content of the concrete is too high for product recommendation.
- Conditions effecting cure due to improper mixing and/or application but not limited to:
- Not mixing each of the components separately before mixing together.
- Not mixing the components together or leaving one of the components out.
- Not mixing the correct product together.
- Not allowing proper induction or sweat times (if applicable).
- Coating film is too thick.
- Stir sticking vs. mechanically mixing.
- Turning the mixing bucket upside down near the end of the coating to let all the product drip out.
- Old product that has been stored. Is the product within its shelf life and how has it been stored if not newly purchased? Don’t mix old material with new if over 6 months old and/or it has been through a freeze.
Consult the Product Data Sheet on the materials being used prior to the application. Knowledge is everything.
