Feather Edging Capability: You can featheredge it without worrying about chipping or spalling. Application: Surface Preparation: First, clean the surface by removing dirt, grease, oil, asphalt, paint, curing compounds, and loose materials. For concrete surfaces, profile it to a minimum CSP#3, and shot blasting is the best. Then, prime the surface with SpecPrime at 100 - 150 sq. ft. per gallon using a brush or broom (not a roller) for even coverage. Porous surfaces may need a second application. Let SpecPrime dry completely before using SpecFlow. Mixing and Application: Start by putting 4 quarts of water in a mixing container, then add one 50 - pound bag of SpecFlow. Use a blending paddle attached to a heavy - duty drill (650 rpm) and mix for 2 to 3 minutes until it's smooth and lump - free. For larger applications, add 25 pounds of clean 3/8 - inch pea gravel per 50 pounds of SpecFlow during the last minute of mixing. For interior floors, pour SpecFlow over the primed substrate. You can spread it with a long - handled spreader or pump it for bigger areas. It self - levels and doesn't need troweling. It can be applied from a feather edge up to 2 inches thick, and up to 5 inches with pea gravel. Usually, it can support foot traffic in 2 to 4 hours, depending on the conditions. Finishing/Curing: SpecFlow self - levels and gives a smooth finish without grinding or sanding. It's self - curing under most conditions. Packaging: It comes in 50 lb. bags, covering about 24 sq. ft. at 1/4 inch thickness. Shelf Life: Store it in a cool, dry place, and it has a 12 - month shelf life. Test Data: At 70°F, it has an initial set time of 50 minutes and a final set time of 80 minutes. It reaches 3000 psi in 1 day, and the strength goes up to 5500 psi by 28 days.
