Waterproof The Porch with Rainguard by Erin Spain.

Erin wrote this very helpful blog review a while back about Advanced Waterproofer. Below is an excerpt with the link to her article. The attached sprayer has been discontinued since this article was written. She decided to Waterproof The Porch.
Waterproof The Porch
We’ve actually been getting quite a bit of rain here in Georgia recently, so the timing was perfect to try out a new product called Rainguard. Rainguard is a waterproofing product designed to protect against the damaging effects of water, salt and weathering. It is designed for driveways, sidewalks, pavers, porches, patios, decks, fences and unpainted exterior walls, but it can also be used on smaller projects like flowerpots or birdhouses. I decided to give it a try on our front porch since we do see a lot of water collect there in certain spots. Our porch is made of brick, and we definitely want to protect it to the best of our ability.
