Interlux Interstain Brown Mahogany Penetrating Wood Stain, Pint (Y42/PT) for Marine Brightwork, Interior and Exterior Timber

Interstain Brown Mahogany is a penetrating marine wood stain formulated to enrich and restore color to brightwork and faded timber above and below deck. Its deep-penetrating formula soaks into the grain to deliver a warm mahogany tone that resists fading, making it a reliable choice for both interior joinery and exterior trim.

Because it can be intermixed with one-pack varnishes, Interstain lets you build a darker, custom finish while keeping the natural beauty of the wood visible. Use it as a stand-alone stain on bare or sanded timber, or blend it into your varnish system to fine-tune the depth of color.
