Abatron Products are Professional Wood Fillers that can be used to repair window sills, wood trim and small log sections rather than replacing the full wood section. These products are professional grade epoxy and resins design for durability. Liquid Wood is an epoxy coating designed to seal the wood, after all rotten wood is removed and before Wood Epoxy, wood filler is applied. We also recommend treating the areas where rotten wood was removed with a borate solution before Liquid Wood or Wood Epox is applied. Please give I Wood Care a call for more details.
