Dry the ipe out of full sun for at least 48 hours before you intend to use it. Ipe dries quickly and will warp if dried too quickly at higher temperatures. Drying can also cause small splits, known as checking, in the ends of the ipe.
Sand gently with fine grit sandpapers, 150-grit or higher. Ipe's grain lends itself to a smoother than usual surface that does not require much sanding. Remove only what is needed to provide a quality finish, as sanding too deep can remove the natural oils that reside just under the surface contributing to drying.
Brush on a coat of boiled linseed oil to help prepare and soften the wood slightly. Apply the oil 8 to 10 hours before cutting for best results.
Use only carbide or diamond tipped blades and bits. Make cuts without forcing, which causes additional friction, contributing to dulling. Use finer tooth hardwood blades for best results.
Pre-drill all nail and screw holes to prevent breaking fasteners and splitting the wood. A 1/8-inch thick bit works well.
Wear dust masks and eye protection to keep the harsh and irritating dust from sensitive tissue. It can cause respiratory irritation and eye inflammation.
Stain your ipe once a year with an oil penetrating stain to maintain constant color. Brush or roll on a stain rated for outdoor use. Reapply as soon as weathering is noticed.
Clean ipe with a pressure washer, if not stained, to remove graying from the surface and restore the color. Do not use harsh brighteners and bleaches, as these contribute to the already dry nature of ipe.
Oil your deck with boiled linseed oil if drying, checking or splintering occur. Apply the oil with a roller or lamb's wool applicator. Linseed is a natural plant oil and can be applied as often as you like.
