I have a wood outside door finished with Bona graphite drifast stain. It needs a new staining, now dull and lightened. Can old stain be left on and a new coat of Bona be applied?
Thankyou

Hi,

The Bona Drifast stain is not an exterior product. It is also to be used in combination with Bona Varnishes.

For these reasons we are unable to assist you with this request.

Sorry,
