How to Install Carpet Padding on Stairs

Measure the steps by width, length and the number of steps to be padded. Remember that the carpet will be laid over the pad; carpet layers place tack strip on the stairs to hold the carpet in place. The pad must not cover the tack strip, so measurements must take this into account.

Cut the padding to size using carpet shears; a sharp utility knife can also be used. There are different types and qualities of carpet padding but all are easy to work with and cut.

Sweep and vacuum the stairs. Dust or other debris interferes with the glue's effectiveness, making it difficult to achieve a successful bond.

Spread the pad glue only on the areas that will come into contact with the pad. This glue is messy and permanent---you must be careful not to apply too much and avoid leaking. The bond formed by this glue lasts for years.

Let the glue dry and set for at least 48 hours before carpet installation to avoid slippage or puckering of the pad.
