I have a treated wood front pourch we have tiled it. The tile pulls away from the risiers on the steps and cracks on the flat edges on some steps. What can I do to keep the tile from pulling away from the risiers and cracking on the steps as well. We have tried wire mesh ? Also is it because of wood has movement and the change in hot & very cold weather throughout the year ? Please help me out im also having grip issues in the winter thanks!!!:huh:
