What should I use to seal a bamboo floor?

I am surprised that this flooring type is not already treated. However it would be best sealed first with one coat of good qiality floor sealer such as Bona Prime. Followed once dry by minimum two coats of Bona Traffic. These are water born polymers which are easy to apply by brush or roller. They are quick drying usually 2 hours between coats. They are also odourless.Tip male sure your gloor is thoroughly clear of dust and other contaminates before hand. Hope this is useful. Regards Heartwood
