Rained exactly 3 hours later. No leaking
Used to patch up stucko damaged caused by woodpeckers who had penetrated the waterproof barrier underneath. Painted much better than traditional stucko patch. This product is self leveling, therefore when applying to walls, need to watch for dripping. I simple ran a paper towel over the drips to smooth product into stucko. Lastly it set as advertised and withstood rain with in just 3 hours of application for over 8 hours.
Garage floor, whole again using DAP 3.0.
Grabbed a caulking gun, punctured the foil after cutting an angle in the tip then went to work on my 25+ year garage floor. This worked quite well and quickly. Final drying color is lighter than the advertised color, but close enough. Seems sturdy and worth the efforts.
Great, high quality product and easy to use
Used this to seal medium sized cracks in concrete and between concrete slabs. Very easy to use because it is self leveling and adheres well to the concrete, forming a uniform seal. It also cured rather quickly as it said it would on the packaging and as it also says on the packaging, only use a high quality latex paint if painting.
