Product Details

Interlux Seam Compound is available in two versions; one for above the waterline (white), and one for below waterline (brown) applications. Seam compound Brown 30 is specifically designed to the fill seams of wooden boat bottoms and to fill keel joints that flex. Brown 30 is a tried and proven performer that remains durable and flexible after immersion to absorb expansion and contraction of planks.

White 31 compound is a tight sealing material used to fill wooden boat hull seams above the waterline. It too remains pliable to allow plank contraction and expansion. Easy to apply with a putty knife. Do not use White seam compound below the waterline. Both compounds exhibit excellent adhesive qualities when applied over properly primed surfaces.
