Futone0.5 Gallon Hand Held Garden Sprayer Water Pump Pressure Sprayers for Lawn and Garden - (2.0L White)

Q: What distance well it spray in stream setting

Distance of spray? Depends on how well the bottle is pumped up. 22 pumps on a full bottle goes 3 to 4 feet. As the pressure goes down, the distance goes down. It's a good bottle for close-in spraying. Pump it up until the release valve begins to sputter. That tells you it's the max pressure obtainable. Don't expect it to carry further than 3 to 4 feet. :-)

Q: Can you use with waterproofing products

NO -- unless you use it for that single use. Waterproofing products are corrosives to plastics and I suspect the nozzle will be destroyed in the process.
