Bona Retarder

Prolongs Bona's waterborne varnishes, both primer and topcoat.

Bona Retarder is an additive that improves the levelling and prolongs the open time of Bona waterborne varnishes, both primers and top coats. It is designed to be used when the indoor humidity is low and/or the temperature of the room is higher than normal.

Using Bona Retarder will reduce the risk of the finish drying too quickly and leaving roller marks in the dried coat. Can also be added to Bona Sportive Paint for lower viscosity and improved levelling.

  • Facilitates application in dry and/or warm climatic conditions
  • Prolongs the open time
  • Reduces the risk of overlapping and discolouration
