For this type of situation, we're going to use Crossover�. As with all chemicals, you want to make sure you're wearing your proper PPE, as in gloves and glasses. To make sure you're achieving the results that you want, start by testing a small area off to the side. With Crossover�, you want to dilute the product five to one with water. And depending on the size of the area that you're working on, there's three different applications. First, we can put it in a bucket and use a bucket and a brush. We use a small hand pump sprayer or we can actually put the product through an injector into a pressure washer and apply it to the surface that we're working on. When it's a small area that you're working on with a bucket and a brush, you want to take your brush and kind of work with it like a pencil and agitate the affected area and then wipe off with a damp cloth. When you're working in a larger area and you're applying the product with a hand-held pump sprayer, start from the top in a sweeping motion, left to right, and apply the product, so it's in a cascade waterfall effect coming down the surface, use a soft bristle brush, agitate the surface and then use a damp cloth, or you can even use a pressure washer and rinse off the surface. In a larger area, when you're using an injector in a pressure washer, you won't need to dilute the product. The product will be diluted as you're pressure washing. Once you apply the product to the injector and the pressure washer, again, take a soft bristle deck brush, agitate the surface a little bit, turn off the injector and then pressure wash the surface off with just water.
