Joint Seal

RamSeal FL-100

Two-component 100% solids zero VOC polyurea joint sealant

Overview

RamSeal FL-100 is a two-component, 100% solids, zero VOC, elastomeric polyurea sealing system designed to act as a crack filler for use with small to large cracks in concrete, masonry, and other cementitious substrates. It provides exceptional adhesion, fast cure times, high chemical resistance, and remains thermally stable from -26°F to 250°F. It may be used under traditional floor coatings or any Ram Urethanes top-coating material.

Key Features

Zero VOC / 100% Solids

Fully solids polyurea formulation with zero VOC — safe for use in occupied spaces including food-processing plants, cold storage, and interior warehouse environments.

Fast Return to Service

Gel time of 3–5 minutes and return to service in just 15–20 minutes under normal conditions, minimizing downtime in high-traffic industrial and commercial floors.

High Elongation & Flexibility

500% ±50% elongation (ASTM D412) and 1/8" mandrel flexibility (ASTM D1737) allow the sealant to accommodate joint movement and thermal cycling without cracking.

Chemical & Abrasion Resistance

Highly chemical resistant and abrasion resistant with Shore A 85 ±5 hardness — suitable for heavy traffic warehouse floors, refrigeration floors, and chemical spill-prone environments.

Typical Applications

  • Concrete crack filling and expansion joints
  • Heavy traffic warehouse and industrial floors
  • Refrigeration and cold storage floors
  • Airports, bridges, and parking decks
  • Food-processing plants and naval decks
  • Walkways, balconies, and pothole road repair
