Garage floor mats are incredibly easy to install, as it is just a matter of rolling them out over a clean and dry hard floor. They usually come with a non-slip backing, which means they will stay in place once laid, but you can secure them with tape if you want extra security. If you need to get the mats into unusual corners, they are easy to cut, so even a DIY job can look like a professional installation. Anyone should be able to install these mats themselves.
