Respond to: Your builder is true about merbau leaching a brown tannin stain when it's new. Nevertheless, the method ceases following a number of months (determined by rainfall) and is just a concern Should the timber is adjacent to a delicate substance, eg. sandstone More about the author pavers beneath, pop over to these guys or mild-coloured render along with, exactly where the brown stain may well depart marks. In the event the deck is suspended over bare earth, the tannin will only wash off into the ground. If staining of adjacent surfaces is not likely you may want to rethink merbau.
