Good afternoon,
Thank you for your question.
Before application of wood preservatives it is recommended to first remove the source of the moisture and any rotten timbers should be removed and replaced.
ProBor® 10.1 Wood Preservative Liquid is intended for application to unpainted, unvarnished timber. Remove all coatings such as varnish and paint before application and all surfaces should be cleaned of dust as far as practically possible.
The ProBor range is for professional use only. Please get in touch directly for further information and trade pricing.
I hope this helps.
Kind regards,
