Coverage
Apply the mixed material onto the prepared surface by brush or roller. This should be in two coats at a target thickness of 10 mil (250 microns) per coat using a practical coverage rate of 37 sq. ft. (3.5 sq meters) per liter per coat. On rough concrete surfaces the coverage rate of the first layer in particular will be significantly reduced.
For spray application sufficient passes should be used to achieve a minimum thickness of 20 mil (500 microns), checking the film thickness regularly with a wet film thickness gauge and brushing out the test marks. As a guide, 1 liter of material should be sufficient to cover 17 sq. ft. (1.6 sq meters) allowing for wastage.
Cure Times
At 68°F (20°C) the applied materials should be allowed to harden for the times indicated below before being subjected to the conditions indicated. These times will be extended at lower temperatures and reduced at higher temperatures:
- Movement without load or immersion – 6 hours
- Light loading – 12 hours
- Full loading/water immersion – 4 days
- Chemical Contact – 7 days
NOTE: PES-CHEM 512 UCEN 194 has been formulated to optimize resistance to mineral acids up to 194°F (90°C) immersion temperature. Expoure to mineral acids will result in the formation of black protective lacquer. In addition, after an initial curing period of at least 12 hours at 68°F (20°C), raising the cure temperature progressively to 140°F-176°F (60 – 80°C) for up to 8 hours will result in improved mechanical, thermal and chemical resistant properties.
Storage Life
If unopened and stored in normal, dry conditions of 59°86°F (30°C), storage life is 5 years.
