Purpose-built polyester filler for travertine holes and voids. Tenax Travertine Filler is a semi-solid polyester filler specifically developed for filling the natural holes, pits, and voids in travertine and similar porous natural stones — a job that standard knife-grade polyester is too stiff for and flowing polyester is too thin for. The semi-solid consistency flows into voids of all sizes without running out, holds its fill level, and cures to a polishable finish that blends with the surrounding travertine surface. Designed primarily for horizontal applications (floors, countertops, and flat surfaces). Accepts color paste for tone matching. Interior use only; not suitable for temperatures below 32°F. 12-month shelf life.
