For cracks or separation of seams that don’t disappear and you want to get rid of or for splits in the wood, you can do the same that the teak factories and we also do at our warehouse…….use a good wood glue and fill them in. The teak factories recommend either Gorilla Glue or TiteBond Premium glue…..our preference is the TiteBond because when it sets up in 8-12 hours… it expands the least and dries clear. A business card or paper clip can be helpful sometimes in pushing the glue in small cracks. Sometimes a clamp can be used in this process depending on where the crack/separation/split is….A little sanding with fine sand paper (150 grit) may be needed afterwards to sand away the excess glue that set up and expanded. After this process, that part of your teak furniture will actually be the strongest part of the furniture piece.
