spray bottle

The first application was done by spray bottle. This did not give the desired coverage. I ordered another quart and applied this in a pump up sprayer. The results were much better. I still have two small areas on my 15′ by 17′ patio cover that allow rain to drip thru. It might be that the cover is 10 years old. Still I had good results. I would suggest that in he future all applications be made with a pump up sprayer. The product did not damage the sprayer.
