How long before you can walk on polyurethane stairs

By Mego Kimani •  Updated: 06/17/23 •  3 min read

The length of time you should wait before walking on your newly polyurethane stairs depends on several factors. key among them is the type of polyurethane, the weather conditions during application, and the thickness of the coat. In most cases, it will be safe to work on the stairs after 24hrs. here is more on what you need to know about drying times of polyurethane.

Factors That Affect Drying Times

The drying time of polyurethane coatings can be influenced by a variety of factors, including:

  1. Temperature and humidity: High humidity levels and low temperatures can prolong drying times, while warmer temperatures and lower humidity can speed up the drying process.
  2. The thickness of the coating: Thicker coatings require more time to dry and cure than thinner coatings.
  3. Type of polyurethane: Some types of polyurethane coatings, such as oil-based and water-based, have different drying times and curing processes.
  4. Ventilation: Proper ventilation is important to allow moisture to escape and to ensure that the coating dries evenly.

Water-based vs oil-based polyurethane drying time compared

Water-based vs. oil-based polyurethane drying time is an important consideration when choosing a coating for your stairs. If time is a factor and you need to get the job done quickly, we recommend using a water-based polyurethane.

Water-based polyurethane has a faster drying time compared to oil-based polyurethane, with some brands drying in as little as two hours. However, it is important to note that drying time should not be confused with curing time, which is the time it takes for the coating to fully harden and reach its maximum durability. Water-based polyurethane typically has a shorter curing time as well, making it an ideal choice for those who need their stairs back in use quickly.

On the other hand, oil-based polyurethane takes longer to dry and cure, requiring more patience and time before the stairs can be used.

How to make your polyurethane dry faster on stairs

There are a number of recommended ways that would work well and give you faster drying times.

  1. Increase ventilation: increasing ventilation allows more airflow that can increase the drying time of your polyurethane coat.
  2. Choosing a water-based polyurethane: Choosing water-based poly over oil is already a step towards a quicker drying time.
  3. Thinner coats: applying thinner coats will help your poly dry faster. but remember that you may have to apply more subsequent layers to build thickness in the long run for added protection and durability.
  4. Space heater: A space heater can be placed in the hallway to heat the air in the room leading to the poly drying much quicker. please note that if you are using oil-based poly the solvents are highly flammable and extra precautions should be observed to avoid fire breakouts.


Polyurethane stairs can be a beautiful and durable addition to any home, but proper care and attention are required to ensure that the coating remains in good condition. It is important to follow the manufacturer’s instructions for drying times and to take care to protect the coating from damage once it is fully cured. With the proper care, your polyurethane stairs will provide years of beauty and functionality to your home.
