DAMTITE Concrete Water Repellent Clear Shield, Safe, Odorless & Clear, Protects Against Water, Ice & Salt Damage, Interior/Exterior Use (1 Gallon)

I only am giving it a 2 star because one of the gallons I ordered had all these chunks and black stuff in it. I first stirred it as directed then put it in my sprayer only to then dump it out cause whatever the black chunks were and made it chunky started to clog my sprayer. It was completely useless. I even tried dumping it in a 5 gallon bucket and using a power stir to hopefully reduce the chunks, but no luck. It was a complete waste. I didn't see the point in asking for a replacement when I supposedly ordered the last 3 in stock. Should have looked elsewhere
