How Can You Apply Polyurethane With A Roller?

  • Prepare rubber gloves and masks to protect yourself from contacting toxic substances and inhaling fumes in polyurethane.

Fill a paint pot with some mineral spirits. Place another paint pot closer to the flat and beside the pot you just prepared. Fill it with a polyurethane formula.

  • Soak a clean rag in mineral spirits and wipe the flat down. By doing this, you can remove almost all dust from the flat. Then wait a few minutes for the substance to evaporate, and you can start the work.

  • Put the nap roller gradually into the pot that contains the mineral spirits and thoroughly humidify its surface. 

Shake off excess mineral turpentines to ensure that they don’t fall in small drops. To properly stick polyurethane, we need a clean, humid paint roller.

  • Then, you put the same roller inside the polyurethane pot and let it soak.
  • Roll a sparse layer of the compound over the wooden floor surface that you want to cover. Roll quickly until the roller no longer has polyurethane.
  • Wait until the compound gets dry. The drying process differs according to ambient temperature, but generally, a new polyurethane coat can be added after three hours.
  • Prepare high sandpaper. After finishing the first layer, you need to sand the flat where you are working to enhance its stability before taking the second one. 

Then soak a clean rag in mineral spirits, remove excess and wipe the flat to clear any dust before moving to the next layer of polyurethane.

  • Repeat the above process until you have added two or three polyurethane layers.
