About Product Overview

Geocel's ELASTMERC SLNT CLR 10.3 is a tripolymer elastomeric sealant made for roofing and exterior repairs where a clean, invisible seal matters. Applied crystal clear, it stays permanently flexible so it moves with the substrate instead of cracking, and it's paintable if you decide to cover it later. Use it on asphalt shingles, modified bitumen, Kynar 500-coated steel, concrete, vinyl, and other common building materials for sealing seams, flashing, and small gaps that need to shed water without showing.

  • 10.3 oz cartridge, covers approximately 8.7-24.8 linear feet depending on bead size
  • Crystal clear finish, paintable once cured
  • Permanently flexible, moisture and mildew resistant for outdoor use
  • Clean up with mineral spirits; made in the USA

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
