When confronted with uneven or rough floors, an excellent option is a self-leveling underlayment. Contractors find self-leveling underlayment to be relatively easy to work with and products that don’t require lots of expensive tools to use. But you need to be aware of the quality levels of the underlayment products that you choose. If you want a product with unquestioned quality integrity, you want to consider Sika’s brand of underlayment. Here are two that we carry.
