FlexRock should be at room temperature when ready to use We recommend Part A be stored at room temperature. No less than 32°F (0°C).

The Part A bucket should be stored upside down for ease of mixing when used. Turn bucket upside (minimum, at least one day) before use.

We recommended Part B be stored at temperatures between 75° to 105°F (24° to 41°C).

Products must be kept free of moisture. Keep the containers closed because the product absorbs moisture from the air over time. Moisture in the product causes it to produce CO2 gas which may cause pressure build-up inside a sealed container.

One FlexRock 5-Gal Kit Covers Aprox 150-250 Sq ft of flat smooth surfaces. We recommend a minimum of 32 mills of coverage. Sq. Ft/Kit 32 ml @ 250 ft.².

Flexible Rock Coating is super versatile it can be applied extra thick for added Roof Coating protection. By applying more than the minimum, you simply add more protection and extend the lifespan even further. This thicker system is perfect for filling cracks and imperfections. A chemical bond is formed between FlexRock and the roof, creating a waterproof casement.

*Coverage rates can vary depending on the type of roof substrate, surface condition and application technique.

1. You will only have 30 to 40 minutes (See curing estimates chart) to apply your coating material (after Part A and Part B are mixed together) to coat your surfaces before the coating material starts to harden.

2. In order to begin coating, the substrate must be dry which is generally not achievable without having the dew point temperature being at least 5°C or 10°F below the substrate temperature.
