Al of Ask the Pool Guy is an installer of ecoFinish. He shares his thoughts and insights about the product and the company because he is truly excited about this product, and the people behind it. ecoFinish is an amazing product. There is a key to it being installed correctly – it needs to be done by an installer that is approved by ecoFinish and who knows what they are doing. Prep of the pool surface is critical, as well as following the ecoFinish protocol to achieve a chemical bond AND a mechanical bond or there could be issues. ecoFinish recommends the epoxy mix be put on with the purdy white paint rollers.
