Floor tiles can give your home a classy feel, but they can also pose a threat to you and others. If the tile has a slippery surface, you can suffer a severe fall. This doesn't mean you should oust the tile in favor of carpeting or any other form of flooring, though. With the proper floor treatment and caution, you can help prevent many household disasters while you keep your tile flooring in top shape.
Sand the surface of the floor with 180-grit sandpaper. Lightly sanding the floor with fine grit sandpaper will not damage your floor, but it adds essential traction to the flooring. Sand by hand if you have a small tiled area but use an electric sander if you have a large tiled area.
Wash your floor with a strong degreaser (not strong enough to strip the tile, though). If oils form on the surface of the tile, it can create some treacherous footing. Cleaning the floor regularly with a degreasing agent will help it maintain a safe amount of traction.
Paint the flooring with sturdy traction paint. This will still show the overall shape of the tiles, making it apparent that you still have a tile floor without the risk of a slippery floor. Clean the floor thoroughly before you paint it and let it dry thoroughly before you attempt to walk on it.
Lay down area rugs on parts of the floor that are especially slippery or prone to wetness. It may cover up a small portion of your tiled floor, but it can also drastically cut down the chances of sustaining a serious injury if you fall. The rug will also keep your feet warmer as you walk across the tile.
