Have you ever wondered why your pool pavers feel excessively slippery? Sure, pavers get slick when they are wet but sometimes they can get super slippery if they are dirty. When it rains, the most dangerous time to drive on the road is within the first half hour after it starts to rain because this is when the oil and grease in the road gets lifted up from the asphalt but has not yet been washed away by excessive rainfall.
The same goes for your pool pavers. When they get wet, the water lifts the oil and grease up to the surface. The difference between rain and pool water though is that rain may be constant – pool water may not eventually wash away this lifted oil and grease. A lot of people don’t think of pool paver cleaning as a safety measure but in this sense, it most certainly is.
