Wait up to week after receiving a shipment of ipe to allow it to become used to the climate and stabilize. If the weather is moist, let the wood dry before beginning construction.
Change from a standard wood saw blade to a carbide tipped one. Use brad point drill bits for drilling starter holes for any nails or screws.
Avoid allowing ipe sawdust to touch bare skin, or to breath it in. The wood itself is harmless, but the sawdust is toxic.
Immediately seal any cut in ipe with a quick-drying exterior polyurethane.This avoids any splitting.
Fasten ipe wood to joists with two #8 trim head screws per board.
Space the boards with 1/16-inch gaps to allow for drainage and wood movement.
